MCQmedium

During an SAP migration, the migration team needs to ensure that all SAP system IDs (SIDs) are unique across the AWS environment. Which AWS service can be used to centrally manage and enforce this uniqueness?

A.AWS Service Catalog

B.AWS Config

C.AWS Resource Access Manager

D.AWS CloudTrail

AnswerA

Service Catalog allows creating a product with constraints that enforce unique SIDs.

Why this answer

AWS Service Catalog can define product portfolios with constraints, including preventing duplicate SIDs. Option B is wrong because AWS Config audits resources but doesn't enforce uniqueness. Option C is wrong because AWS Resource Access Manager shares resources, not manages SIDs.

Option D is wrong because AWS CloudTrail logs API calls.

A company is migrating an on-premises SAP HANA database to AWS. They want to use AWS DMS for ongoing replication. Which TWO prerequisites must be met before starting the replication? (Choose TWO.)

Select 2 answers

A.The source database must be running on an EC2 instance.

B.The source database must have binary logging enabled (for CDC).

C.The source database must be accessible from the DMS replication instance.

D.The target database must be Amazon RDS for Oracle.

E.The schema must be converted using AWS SCT first.

AnswersB, C

Binary logging is required for change data capture.

Why this answer

For ongoing replication (CDC) with AWS DMS, binary logging must be enabled on the source database (Option B). Additionally, the source database must be accessible from the DMS replication instance (Option C). Option A is incorrect because the source does not need to be running on EC2; any supported database can be used.

Option D is incorrect because the target database in this migration scenario is SAP HANA on AWS, not Amazon RDS for Oracle. Option E is incorrect because AWS Schema Conversion Tool (SCT) is used for schema conversion, not a prerequisite for DMS replication.

MCQeasy

A company is migrating an SAP NetWeaver system from on-premises to AWS. They plan to use the same SAP SID and keep the same hostname. The migration will be performed using SAP Software Provisioning Manager (SWPM) with the option 'System Rename' set to 'No'. What must be configured in the AWS environment to ensure the system functions correctly?

A.Ensure the same private IP address is assigned to the Amazon EC2 instance

B.Update the DNS records to point to the new public IP

C.Change the SAP SID to a new value

D.Assign a different private IP address to avoid conflicts

AnswerA

Matching IP avoids reconfiguration of application and database connections.

Why this answer

The system uses the same hostname and SAP SID. To avoid reconfiguration, the Amazon EC2 instance must have the same private IP address as the on-premises hostname resolves to, or the hostname must be resolvable via DNS or /etc/hosts. Option B is incorrect because updating DNS records to point to a new public IP is unnecessary when the same private IP is used.

Option C is incorrect because the same SAP SID is allowed and does not need to be changed. Option D is incorrect because assigning a different private IP would require updating hostname resolution, which defeats the purpose of keeping the same hostname.

MCQmedium

An organization is migrating a legacy SAP ERP system to AWS. The current system runs on IBM AIX with Oracle Database. They plan to use SAP HANA on AWS. Which AWS service should they use to assess the source system's readiness and generate a migration plan?

A.AWS CloudEndure Migration

B.AWS Application Migration Service (AWS MGN)

C.AWS Database Migration Service (DMS)

D.AWS Schema Conversion Tool (SCT)

AnswerB

AWS MGN provides assessment, replication, and automated migration.

Why this answer

AWS Application Migration Service (AWS MGN) is the correct service for assessing source system readiness and generating a migration plan for SAP systems to AWS. It provides automated readiness checks and migration orchestration. Option A (AWS CloudEndure Migration) is a predecessor of AWS MGN and is now integrated; it is not the recommended current service.

Option C (AWS Database Migration Service - DMS) is for database migration only, not full system assessment. Option D (AWS Schema Conversion Tool - SCT) handles schema conversion, not assessment or migration planning.

A company is migrating a legacy application to AWS. The application requires a static IP address that must not change after migration. Which networking component should be used to ensure the application's public IP remains consistent?

A.Elastic IP address

B.Internet Gateway

C.VPC Peering

AnswerA

An Elastic IP address is a static public IPv4 address that can be associated with an EC2 instance or a Network Load Balancer, ensuring the application's public IP remains consistent.

Why this answer

An Elastic IP address is a static public IPv4 address that can be associated with an EC2 instance or a Network Load Balancer, ensuring the application's public IP remains consistent. Option B (Internet Gateway) is used for VPC internet access but does not provide a static IP. Option C (VPC Peering) is for connecting VPCs.

Option D (NAT Gateway) is for outbound traffic.

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. They need to minimize downtime and ensure data consistency. Which AWS service should be used for the initial data load?

A.AWS Database Migration Service (AWS DMS)

B.AWS Snowball Edge

C.AWS Schema Conversion Tool (AWS SCT)

D.AWS DataSync

AnswerA

AWS DMS supports full load and ongoing replication for minimal downtime.

Why this answer

AWS DMS can perform a full load and then ongoing replication to keep the target in sync, minimizing downtime. AWS SCT helps with schema conversion but not data transfer. AWS DataSync is for file data, not databases.

AWS Snowball is for large offline data transfer but not suitable for minimal downtime with replication.

MCQmedium

A company is migrating its SAP Business Suite system from on-premises to AWS. The system uses a Sybase ASE database. The migration team has limited Sybase expertise. They want to minimize the operational overhead after migration. Which database migration approach should they choose?

A.Use AWS MGN to replicate the entire Sybase server to EC2, then perform a system upgrade to SAP HANA.

B.Use SAP Software Update Manager (SUM) with Database Migration Option (DMO) to migrate the system to SAP HANA on EC2.

C.Use AWS DataSync to copy the Sybase data files to EBS and attach to an EC2 instance running Sybase.

D.Use AWS DMS to migrate the Sybase database to Amazon RDS for Sybase.

AnswerB

DMO allows migrating from Sybase to HANA as part of a system update, reducing overhead and leveraging SAP expertise.

Why this answer

Migrating from Sybase ASE to SAP HANA is a strategic move that reduces operational overhead because HANA is a modern in-memory database with better performance and simpler management. SAP Software Update Manager (SUM) with Database Migration Option (DMO) is the official SAP tool to perform this migration while also upgrading the SAP system. This approach minimizes manual effort and leverages SAP expertise.

Option A is incorrect because AWS Application Migration Service (MGN) would replicate the entire Sybase server, keeping Sybase and not reducing overhead. Option C is incorrect because AWS DataSync is designed for file-based transfers, not database replication. Option D is incorrect because AWS DMS does not support Sybase as a target database, and Amazon RDS does not support Sybase; Sybase on AWS would require self-managed EC2, increasing overhead.

A company is migrating a SAP database to Amazon RDS. The IAM policy shown in the exhibit is attached to a user. Which action is allowed by this policy?

A.Create a new RDS instance.

B.Modify the production SAP RDS instance.

C.Delete the production SAP RDS instance.

D.Only read RDS instances.

AnswerB

Modifying the production SAP RDS instance is allowed because ModifyDBInstance is covered by rds:* and is not denied for prod-sap-db.

Why this answer

The policy allows all RDS actions (rds:*) on all resources, with an explicit deny for DeleteDBInstance on the prod-sap-db resource. This means the user can perform any RDS operation except deleting the specific production SAP RDS instance. Therefore, the user is allowed to modify the production SAP RDS instance (ModifyDBInstance), making Option B the correct answer.

Creating a new RDS instance (CreateDBInstance) is generally allowed, but it is not the action directly related to the production instance in this scenario. Option C is denied explicitly. Option D is incorrect because the policy allows write operations.

A company is migrating an SAP ERP system to AWS. The SAP application runs on a Windows Server with an MSSQL database. The migration must be completed within a strict 4-hour downtime window. The current database is 500 GB. Which migration strategy should be used to meet the downtime requirement?

A.Use SAP SWPM export/import to migrate the database

B.Use an SAP-certified backup/restore tool (e.g., Commvault) to restore to Amazon EC2 with MSSQL

C.Use AWS DMS with ongoing replication, then cutover

D.Use AWS CloudEndure Migration to replicate the entire server

AnswerB

Backup/restore can be faster and is supported for MSSQL on EC2.

Why this answer

For migrating an SAP ERP system with MSSQL database to AWS within a 4-hour downtime window, using an SAP-certified backup/restore tool (e.g., Commvault) to restore to Amazon EC2 with MSSQL is the best approach. This method leverages native MSSQL backup and restore capabilities, which are optimized for large databases and can complete within the downtime window. Option A (SAP SWPM export/import) is typically slower and may exceed 4 hours.

Option C (AWS DMS with ongoing replication) is not ideal because DMS may not fully support SAP-specific schemas and could introduce compatibility issues, and the cutover may not be faster than backup/restore. Option D (AWS CloudEndure Migration) is designed for server-level replication, not database-optimized transfer, and may not meet the strict time constraint.

A company is migrating an SAP HANA database to AWS. Which TWO of the following are valid options for running SAP HANA on AWS? (Choose 2)

Select 2 answers

A.Amazon RDS for SAP HANA

B.Amazon EC2 instances with Amazon EBS storage

C.AWS Lambda

D.AWS Fargate

E.AWS HANA Large Instances (bare metal)

AnswersB, E

EC2 with EBS is a common deployment option.

Why this answer

SAP HANA can run on EC2 instances with EBS or on AWS HANA Large Instances. RDS for SAP HANA is not available. Lightsail is not suitable for HANA.

Fargate is for containers.

A company is planning to migrate a critical application to AWS using the 7 Rs migration strategy. The application is currently running on a large VMware VM. Which THREE strategies are appropriate for this migration? (Choose three.)

Select 3 answers

A.Rehost: Use AWS VM Import/Export to migrate the VM to EC2

B.Retire: Decommission the application as it is no longer needed

C.Refactor: Re-architect the application to use microservices

D.Replatform: Migrate to Amazon RDS for the database layer

E.Retain: Keep the application on-premises

AnswersA, C, D

Direct lift-and-shift of the VM.

Why this answer

Rehost (A) is appropriate because AWS VM Import/Export allows you to migrate VMware VMs directly to Amazon EC2 as AMIs, enabling a lift-and-shift migration with minimal changes. This is a core 7 Rs strategy for moving existing virtualized workloads to AWS.

Exam trap

The trap here is that candidates may confuse Retire with decommissioning an application that is still needed, or assume Retain is a valid migration strategy when the requirement is to move to AWS.

MCQmedium

An SAP system on AWS is experiencing performance issues. The system uses a shared file system (SAP transport directory) mounted from an NFS server. During migration, the team wants to improve performance and reduce complexity. Which AWS service should replace the NFS server?

A.Amazon S3 with S3FS

B.Amazon FSx for Windows File Server

C.AWS Storage Gateway (file gateway)

D.Amazon EFS

AnswerD

EFS provides a scalable, managed NFS file system that is ideal for SAP transport directories.

Why this answer

Amazon EFS provides a fully managed NFS file system that can be shared across multiple EC2 instances, making it an ideal replacement for the NFS server in SAP transport directory scenarios. Option A (Amazon S3 with S3FS) is incorrect because S3 is object storage and S3FS is a FUSE-based tool that adds complexity and can cause performance issues, not suitable for SAP transport. Option B (Amazon FSx for Windows File Server) is incorrect because it uses SMB protocol, while SAP transport directories typically require NFS and run on Linux instances.

Option C (AWS Storage Gateway file gateway) adds unnecessary complexity as it is designed for hybrid storage and caching, not as a direct NFS replacement for this use case.

A company is using AWS Database Migration Service (DMS) to migrate an SAP HANA database from on-premises to Amazon RDS for SAP HANA. The migration task fails with the error shown. Which step should the administrator take to resolve this?

A.Change the source database character set to ISO-8859-1.

B.Modify the DMS task to include character set conversion settings.

C.Create a new RDS instance with the correct character set.

D.Use AWS Server Migration Service (SMS) instead of DMS.

AnswerB

DMS supports character set conversion.

Why this answer

The error indicates a character set mismatch between the source and target databases. AWS DMS can handle character set conversion if configured correctly. By modifying the DMS task to include character set conversion settings, the administrator can resolve the mismatch without altering the source or creating a new instance.

Option A is incorrect because changing the source database character set is unnecessary and could impact other applications. Option C is incorrect because creating a new RDS instance is overkill; the issue lies in the DMS task configuration. Option D is incorrect because AWS Server Migration Service (SMS) is for server-level migration, not database migration.

MCQhard

A company is migrating a large SAP landscape to AWS. The migration plan includes using AWS CloudEndure Migration for the application servers. However, the SAP database requires a different approach. Which database migration method is recommended for an SAP HANA database?

A.Use AWS Schema Conversion Tool (SCT) to convert the HANA schema.

B.Use AWS CloudEndure Migration for both application and database servers.

C.Use AWS DMS with Oracle as a source and HANA as target.

D.Use SAP HANA System Replication (HSR).

AnswerD

HSR is the native HANA replication method.

Why this answer

The recommended method for migrating an SAP HANA database is SAP HANA System Replication (HSR). HSR provides a database-aware, block-level replication with near-zero downtime, making it ideal for SAP HANA migrations. Option A is incorrect because AWS Schema Conversion Tool (SCT) is used for converting schemas between different database engines (e.g., Oracle to Amazon RDS), not for HANA-to-HANA migration.

Option B is incorrect because AWS CloudEndure Migration performs host-level replication and lacks database consistency features required for SAP HANA. Option C is incorrect because AWS DMS does not support SAP HANA as a target database; it is used for heterogeneous migrations to AWS database services.

An organization is migrating their SAP ERP system to AWS and needs to set up a disaster recovery (DR) site in another AWS region. They want to use AWS Elastic Disaster Recovery (DRS) for SAP HANA. The source HANA system is running on-premises on a physical server. They have installed the DRS agent on the source server. During the initial replication, they notice that the data transfer is very slow. What should they do to improve replication speed?

A.Switch to asynchronous replication mode

B.Use Amazon RDS for HANA as the DR target instead of EC2

C.Increase the size of the staging area subnet

D.Increase the number of concurrent data streams in the DRS agent configuration

AnswerD

More streams can utilize available bandwidth better.

Why this answer

AWS Elastic Disaster Recovery (DRS) allows configuring multiple concurrent data streams to increase network throughput and improve replication speed. Option A is incorrect because DRS already uses asynchronous replication by default; switching to asynchronous does not change the current mode. Option B is incorrect because Amazon RDS for HANA is a managed database service, not a DR target for DRS; DRS replicates to EC2 instances.

Option C is incorrect because the staging area subnet size affects storage capacity, not replication speed.

During the migration of an SAP ERP system to AWS, the SAP application team reports that after migrating the database to Amazon RDS for SAP HANA, batch jobs that previously ran in 2 hours now take 5 hours. The system uses AWS Direct Connect with adequate bandwidth. Which action is most likely to resolve this performance issue?

A.Enable Multi-AZ deployment for RDS.

B.Increase the RDS instance size and storage IOPS.

C.Reduce the automated backup retention period.

D.Increase the Direct Connect bandwidth.

AnswerB

Larger instance provides more CPU and memory for HANA.

Why this answer

The performance degradation is likely due to insufficient compute or IOPS capacity on the RDS instance compared to the original on-premises HANA system. Increasing the instance size (more vCPUs and memory) and storage IOPS directly addresses the bottleneck. Multi-AZ (Option A) provides high availability but does not improve performance.

Reducing backup retention (Option C) has no impact on query execution. Since Direct Connect bandwidth is adequate (Option D), increasing it would not help. Therefore, Option B is the most effective action.

During an SAP migration, the team needs to transfer a large number of small files (SAP transport requests) from on-premises to AWS. Which AWS service is most cost-effective for this transfer?

A.AWS Transfer Family (SFTP)

B.AWS Snowmobile

C.AWS DataSync

D.AWS Snowcone

AnswerC

AWS DataSync is optimized for efficient transfer of millions of small files using parallel network transfers and is cost-effective for most volumes, making it the best choice here.

Why this answer

AWS DataSync is optimized for efficiently transferring millions of small files, such as SAP transport requests, over the network, and is cost-effective for most data volumes without network constraints. It uses parallel threading and metadata handling to accelerate small-file transfers. In contrast, option D (AWS Snowcone) incurs shipping costs and device rental fees, making it less cost-effective for this type of transfer.

MCQmedium

A company is migrating its SAP Business Warehouse (BW) system from on-premises to AWS. The system uses IBM DB2 as the database and is 2 TB in size. The company wants to use the SAP BW/4HANA version on AWS. The migration must be completed within a 72-hour window. The company has a 1 Gbps AWS Direct Connect connection. The migration team decides to use the SAP Software Update Manager (SUM) with the Database Migration Option (DMO) to migrate and upgrade to BW/4HANA. During the migration, they encounter an error that the source DB2 database has a tablespace that uses automatic storage and is larger than 2 TB. The SUM DMO tool stops with an error indicating insufficient space in the target SAP HANA database. The target SAP HANA system is provisioned with 1 TB of memory and 2 TB of disk storage. The team needs to proceed with the migration. Which action should the team take to resolve this issue?

A.Use AWS Database Migration Service (AWS DMS) to migrate the data directly to SAP HANA, bypassing SUM DMO.

B.Increase the disk storage of the SAP HANA instance to at least 2.5 TB to accommodate the migrated data.

C.Compress the DB2 database on the source side to reduce its size before migration.

D.Split the migration into two phases: migrate the data using AWS DMS first, then use SUM for the upgrade.

AnswerB

Increasing disk storage provides the necessary space for the migration.

Why this answer

The error occurs because the source DB2 database's tablespace using automatic storage exceeds the target SAP HANA's disk capacity of 2 TB. The SUM DMO tool requires enough space to store the migrated data during the conversion process. Increasing the disk storage of the SAP HANA instance to at least 2.5 TB (or larger to accommodate the full 2 TB source plus overhead) resolves the space issue and allows the migration to proceed.

Option A is incorrect because AWS DMS does not support SAP HANA as a target for direct migration. Option C is incorrect because DB2 compression reduces storage but does not address the automatic storage tablespace size limitation that causes the SUM error. Option D is incorrect because splitting the migration into DMS and SUM phases is not supported for DB2 to HANA; SUM DMO is the recommended tool for this combined migration and upgrade.

A.AWS OpsWorks

B.AWS CodeDeploy

C.AWS CloudFormation

D.AWS Elastic Beanstalk

AnswerC

CloudFormation allows you to define and provision AWS infrastructure declaratively.

Why this answer

AWS CloudFormation allows you to define infrastructure as code. OpsWorks is for configuration management. Elastic Beanstalk is for application deployment.

A.Create a separate sandbox environment that is isolated from production and uses mock endpoints for RFC calls.

B.Use the same RFC destinations as production but disable the external system.

C.Set up a VPN between the sandbox and the external system to test real connectivity.

D.Configure the sandbox to use the production RFC endpoints but with read-only access.

AnswerA

Isolation prevents unintended effects on production.

Why this answer

Using a sandbox environment disconnected from the production system prevents accidental data changes or impacts. Options B, C, D are incorrect because they either involve production connections or are not best practices.

A company is migrating an SAP Business Suite system to AWS. The system runs on AIX on IBM Power Systems. The company wants to rehost the system on AWS using a lift-and-shift approach. Which AWS service can replicate the AIX operating system to run on AWS?

A.AWS CloudEndure Migration

B.AWS Database Migration Service (AWS DMS)

C.AWS Server Migration Service (AWS SMS)

D.AWS Application Migration Service (AWS MGN)

AnswerD

AWS MGN supports AIX via the AWS Replication Agent for lift-and-shift.

Why this answer

AWS Application Migration Service (AWS MGN) supports agent-based migration for AIX via the AWS Replication Agent. Option A (AWS CloudEndure Migration) has been rebranded as AWS MGN. Option B (AWS SMS) does not support AIX.

Option C (AWS Database Migration Service) is for databases, not OS.

An IAM policy for a migration team is shown in the exhibit. The team is unable to start a DMS replication task. What is the most likely missing permission?

A.dms:CreateReplicationInstance and dms:CreateEndpoint

B.s3:ListBucket

C.kms:Decrypt

D.ec2:CreateNetworkInterface

AnswerD

Correct. DMS uses ec2:CreateNetworkInterface to create an elastic network interface in the VPC for the replication instance when starting a task. Without this permission, the task fails to start.

Why this answer

To start a DMS replication task, the IAM policy must include permissions for DMS to create network interfaces in the VPC. The ec2:CreateNetworkInterface permission is required because DMS dynamically creates an elastic network interface for the replication instance when the task starts. The other options are not the most likely missing permission: dms:CreateReplicationInstance and dms:CreateEndpoint are needed for creating resources, not for starting an existing task; s3:ListBucket is unrelated; kms:Decrypt is only needed if using encrypted endpoints, which is not indicated.

Exam trap

Candidates often confuse the permissions needed to create DMS resources with those needed to start a task. Starting a task requires dms:StartReplicationTask and ec2:CreateNetworkInterface, not the create actions for instances or endpoints.

MCQmedium

A company is using AWS DMS to migrate an SAP database. The full load is complete, but the CDC latency is high. Which step should the company take to reduce latency?

A.Increase the compute capacity of the DMS replication instance.

B.Increase the size of the target database instance.

C.Restart the DMS replication task.

D.Disable change data capture (CDC) on the source database.

AnswerA

A larger replication instance can process CDC faster.

Why this answer

Increasing the compute capacity of the DMS replication instance provides more resources to process CDC changes, reducing latency. Option B is incorrect because increasing the target database size does not directly affect DMS replication performance. Option C is incorrect because restarting the task does not address the underlying resource constraint and may cause temporary downtime.

Option D is incorrect because disabling CDC would stop replication entirely, not reduce latency.

MCQeasy

A company is migrating a SAP HANA database to AWS. Which storage configuration is recommended for SAP HANA to meet performance requirements?

A.Amazon EC2 instance store volumes

B.Amazon S3 as a block device

C.Amazon EBS gp2 volumes

D.Amazon EBS io2 Block Express volumes

AnswerD

io2 Block Express offers high IOPS and low latency.

Why this answer

Amazon EBS io2 Block Express volumes are the recommended storage configuration for SAP HANA on AWS because they provide up to 4,000 MB/s throughput per volume and 256,000 IOPS, with 99.999% durability. This meets the high-performance, low-latency requirements of SAP HANA, which demands consistent sub-millisecond latency for its columnar in-memory database operations. io2 Block Express volumes also support multi-attach for SAP HANA scale-out configurations and are the only EBS volume type validated by SAP for production HANA workloads.

Exam trap

The trap here is that candidates often choose gp2 volumes (Option C) because they are familiar with general-purpose workloads, but they fail to recognize that SAP HANA requires sustained high IOPS and low latency that only io2 Block Express volumes can guarantee, as gp2's burst model cannot maintain performance for production HANA databases.

How to eliminate wrong answers

Option A is wrong because Amazon EC2 instance store volumes are ephemeral and data is lost on instance stop or termination, making them unsuitable for persistent SAP HANA data and log storage. Option B is wrong because Amazon S3 is an object storage service, not a block device, and cannot be mounted as a filesystem or provide the low-latency block-level access required by SAP HANA. Option C is wrong because Amazon EBS gp2 volumes offer burstable performance with a baseline of 3 IOPS per GB and maximum 16,000 IOPS per volume, which is insufficient for the sustained high IOPS and throughput demands of production SAP HANA workloads.

Which TWO AWS services can be used to monitor the performance of an SAP HANA database on AWS? (Select TWO.)

Select 2 answers

A.AWS Trusted Advisor

B.Amazon CloudWatch

C.AWS X-Ray

D.Amazon RDS Performance Insights

E.AWS Config

AnswersB, D

Amazon CloudWatch can monitor SAP HANA metrics such as CPU, memory, and disk I/O, making it a valid choice.

Why this answer

Amazon CloudWatch (option B) can monitor SAP HANA metrics such as CPU, memory, and disk I/O via custom metrics or the SAP HANA plugin. Amazon RDS Performance Insights (option D) provides database-specific performance metrics and SQL-level analysis when SAP HANA is deployed on Amazon RDS. Option A is incorrect because AWS Trusted Advisor offers best-practice checks, not real-time performance monitoring.

Option C is wrong because AWS X-Ray traces application requests, not database performance. Option E is wrong because AWS Config audits configuration changes, not performance.

Exam trap

Candidates may mistakenly choose AWS Trusted Advisor (Option A) for monitoring, but it only provides recommendations, not performance metrics.

A company is migrating an SAP ERP system to AWS. The SAP application servers use a shared /sapmnt filesystem. Which AWS storage solution is most suitable for this shared filesystem with high availability?

A.Amazon S3 with a mount point

B.Amazon FSx for Windows File Server

C.Amazon EBS with Multi-Attach enabled

D.Amazon EFS

AnswerD

EFS provides a shared NFS filesystem with high availability.

Why this answer

(Amazon EFS) is correct because Amazon EFS is a managed NFS filesystem that provides high availability and can be shared across multiple EC2 instances, making it suitable for the shared /sapmnt filesystem required by SAP. Option A (Amazon S3) is wrong because S3 is object storage, not a POSIX-compliant filesystem, and cannot be mounted as a shared filesystem. Option B (Amazon FSx for Windows File Server) is incorrect because SAP typically runs on Linux, and FSx for Windows is designed for Windows workloads.

Option C (Amazon EBS with Multi-Attach) is not ideal because EBS Multi-Attach has limitations (max 16 instances, single Availability Zone) and is not as scalable or resilient as EFS for this use case.

Exam trap

The /sapmnt filesystem must be accessible from multiple application servers simultaneously. While EBS Multi-Attach can technically attach a volume to multiple instances, it is not recommended for SAP workloads due to limited concurrency and lack of managed high availability. EFS is the correct choice.

A company is migrating an SAP ERP system to AWS using an SAP-certified backup/restore method. After restoring the database to Amazon RDS for SAP ASE, the SAP application fails to start with an error 'database connection refused'. The security group allows inbound traffic from the application server. What is the most likely cause?

A.The RDS instance is in a 'stopped' state

B.The security group does not allow outbound traffic

C.The SAP application is using the wrong database hostname or port

D.The RDS instance is in a different VPC than the application server

AnswerC

After migration, the hostname/port may differ; need to update SAP profile.

Why this answer

After restoring the database to Amazon RDS, the database endpoint (hostname and port) changes. The SAP application likely still uses the old connection parameters, leading to a 'connection refused' error. Option A is incorrect because, although a stopped RDS instance would also cause this error, after a restore the instance is automatically started and running; a stopped state is unlikely.

Option B is incorrect because outbound traffic rules are not required for inbound connections; the inbound rule on the database security group is sufficient. Option D is incorrect because different VPCs would typically result in 'no route to host' or timeout errors, not 'connection refused'.

A company wants to migrate its SAP BusinessObjects system to AWS. The system includes a CMS database that runs on Microsoft SQL Server. The company wants to use AWS DMS to migrate the database with minimal downtime. Which migration method should they use?

A.Snapshot restore to Amazon RDS

B.Full load with one-time restore

C.Full load with ongoing replication (change data capture)

D.Full load only

AnswerC

Ongoing replication syncs changes, minimizing downtime.

Why this answer

Ongoing replication (change data capture) allows DMS to keep the target database in sync with the source, minimizing downtime. Options A, B, D are incorrect because full load only, one-time restore, or snapshot restore do not minimize downtime.

A company is migrating a SAP system to AWS and wants to use AWS Systems Manager for patching. Which TWO prerequisites are required to use AWS Systems Manager Patch Manager?

Select 2 answers

A.The EC2 instance must be in a public subnet.

B.The EC2 instance must be running Amazon Linux 2.

C.The AWS Systems Manager Agent (SSM Agent) must be installed on the EC2 instance.

D.An IAM role with permissions for Systems Manager must be attached to the EC2 instance.

E.A maintenance window must be configured with a reboot option.

AnswersC, D

Correct: The SSM Agent must be installed and running on the instance to enable patching via Patch Manager.

Why this answer

Correct options are C and D. The SSM Agent must be installed and running on the EC2 instances (C), and the instances must have an IAM role that grants Systems Manager permissions (D). Option A is incorrect because Patch Manager works with instances in private subnets as long as they have outbound internet access or a VPC endpoint.

Option B is incorrect because Patch Manager supports multiple operating systems, not just Amazon Linux 2. Option E is incorrect because a maintenance window is not strictly required for Patch Manager; patching can be done on demand.

A company is migrating its SAP application from on-premises to AWS. The SAP application uses a shared file system (NFS) for transport directories. Which AWS service should the company use to replace the on-premises NFS?

A.Amazon FSx for Windows File Server

B.Amazon S3

C.Amazon EBS

D.Amazon EFS

AnswerD

Amazon EFS supports NFS and can be shared across instances for SAP transport directories.

Why this answer

Amazon EFS provides a scalable NFS file system that can be shared across multiple EC2 instances, making it suitable for SAP transport directories. Option A is wrong because Amazon FSx for Windows File Server uses SMB protocol, not NFS. Option B is wrong because Amazon S3 is object storage, not a file system.

A company is migrating its SAP ERP system to AWS using the SAP S/4HANA migration approach. They need to replicate the source system continuously to the target before cutover. Which AWS service should be used for this continuous replication?

A.AWS Schema Conversion Tool (SCT)

B.AWS Server Migration Service (SMS)

C.AWS Database Migration Service (DMS)

D.AWS CloudEndure Migration

AnswerD

AWS CloudEndure Migration provides continuous block-level replication for entire servers, including SAP systems. It is the appropriate service for replicating the source system continuously to AWS before cutover in SAP S/4HANA migrations.

Why this answer

AWS CloudEndure Migration provides continuous block-level replication from on-premises servers to AWS, making it suitable for SAP S/4HANA migrations requiring ongoing replication before cutover. AWS SCT (A) is for schema conversion, not replication. AWS SMS (B) migrates entire servers but does not support continuous replication.

AWS DMS (C) can replicate databases but has limitations for SAP-specific workloads and is not the recommended service for SAP S/4HANA continuous replication. Therefore, AWS CloudEndure (D) is the correct choice.

B.Amazon S3

C.AWS Database Migration Service

D.AWS Backup

E.Amazon EFS

AnswersB, D

SAP HANA can back up directly to S3 using the S3 API.

Why this answer

Amazon S3 is correct because it can be used as a target for SAP HANA backup and recovery using the SAP HANA Backup to S3 feature, which allows direct backup of HANA databases to S3 buckets via the SAP HANA Studio or hdbsql commands. AWS Backup is correct because it provides a fully managed backup service that can automate and centralize backups of SAP HANA databases running on Amazon EC2 instances, using the AWS Backup console or API to create and manage backup policies.

Exam trap

A global company is migrating its SAP ERP system to AWS. The system runs SAP ECC on IBM AIX with Oracle Database. The company plans to move to SAP S/4HANA on AWS. The source system is 5 TB in size. The network bandwidth between the on-premises data center and AWS is 100 Mbps. The migration must be completed within a 2-week window with minimal downtime. The company has a SAP license that allows running S/4HANA on certified hardware. They have already used AWS SCT to convert the database schema to SAP HANA-compatible format. They now need to execute the data migration. The team is considering the following options: Option A: Use AWS DMS with ongoing replication from Oracle to HANA, then perform a final cutover. Option B: Use AWS Snowball Edge to transfer the Oracle backup files to AWS, then restore to HANA. Option C: Use AWS DataSync to copy the Oracle data files to Amazon EFS, then import into HANA. Option D: Use SAP HANA system replication from the source Oracle database to the target HANA database. Which option is the most feasible and efficient for this migration?

A.Use SAP HANA system replication from the source Oracle database to the target HANA database

B.Use AWS Snowball Edge to transfer the Oracle backup files to AWS, then restore to HANA

C.Use AWS DataSync to copy the Oracle data files to Amazon EFS, then import into HANA

D.Use AWS DMS with ongoing replication from Oracle to HANA, then perform a final cutover

AnswerD

DMS supports heterogeneous migrations and ongoing replication to minimize downtime.

Why this answer

The most feasible because AWS DMS supports heterogeneous migrations from Oracle to SAP HANA, and the ongoing replication capability minimizes downtime during the cutover. Option A (SAP HANA system replication) is incorrect because it requires the source database to already be SAP HANA, not Oracle. Option B (Snowball Edge) is inefficient for this scenario because restoring from backup files does not provide ongoing replication, and the 2-week window with minimal downtime would be difficult to achieve.

Option C (DataSync to EFS) is designed for file transfers, not database migration, and importing into HANA would require additional complex steps. The schema conversion has already been done with AWS SCT, so DMS can handle the data migration efficiently.

A company is migrating an SAP NetWeaver system to AWS using the AWS Application Migration Service (AWS MGN). The source server runs SUSE Linux Enterprise Server (SLES) 12 SP5. After the cutover, the SAP application fails to start with an error indicating that the hostname resolution fails. The target EC2 instance has the same hostname as the source. What is the most likely cause?

A.The network configuration file /etc/sysconfig/network was not replicated

B.The /etc/hosts file on the target instance still references the source server's old private IP address

C.The source server's operating system is not supported by AWS MGN

D.The target instance is not registered in Amazon Route 53 private hosted zone

AnswerB

After migration, the target instance gets a new IP; /etc/hosts must be updated to reflect the new IP.

Why this answer

AWS MGN replicates the entire disk, including the /etc/hosts file. After cutover, the target EC2 instance gets a new private IP address, but the /etc/hosts file still contains the source server's old private IP. This causes hostname resolution to fail because the SAP application tries to resolve the hostname to the old IP.

Option A is incorrect because /etc/sysconfig/network is not directly related to hostname resolution failure. Option C is incorrect because SLES 12 SP5 is supported by AWS MGN. Option D is incorrect because Route 53 private hosted zone is not required for hostname resolution if /etc/hosts is correctly configured.

A company is migrating a legacy on-premises application to AWS. The application uses a MySQL database with a complex stored procedure that runs every hour and takes approximately 10 minutes to complete. The company wants to minimize downtime during migration. Which TWO approaches should the company use to migrate the database?

Select 2 answers

A.Use AWS DMS with a full load only, without ongoing replication, and schedule a cutover window.

B.Use AWS Database Migration Service (DMS) with ongoing replication from the source MySQL database to an Amazon RDS for MySQL instance.

C.Set up an Amazon Aurora MySQL DB cluster and use AWS DMS with the on-premises MySQL database as the source and the Aurora cluster as the target, enabling ongoing replication.

D.Take a full database dump using mysqldump and import it into an Amazon RDS for MySQL instance during a planned maintenance window.

E.Create an Amazon RDS for MySQL read replica from the on-premises database.

AnswersB, C

This approach minimizes downtime by continuously replicating changes until cutover.

Why this answer

AWS DMS with ongoing replication allows continuous synchronization from the source MySQL database to Amazon RDS for MySQL, minimizing downtime during migration. The complex stored procedure that runs hourly and takes 10 minutes is handled seamlessly as DMS captures ongoing changes, enabling a controlled cutover with minimal disruption.

Refer to the exhibit. An SAP administrator is creating an IAM policy for a migration user who will use AWS DMS to migrate an SAP database to Amazon RDS. The migration also requires reading from an S3 bucket containing source database export files and writing the DMS logs to another S3 bucket. The policy above is attached. Which required permission is MISSING from this policy?

A.dms:TestConnection

B.s3:ListBucket

C.rds:ModifyDBInstance

D.dms:CreateEndpoint

AnswerD

DMS requires CreateEndpoint to define source and target databases.

Why this answer

The policy includes dms:CreateReplicationTask and permissions for S3 and RDS, but it lacks dms:CreateEndpoint, which is required to create source and target endpoints for DMS migrations. Without this permission, the migration user cannot set up the endpoints necessary for the replication process.

Option A (dms:TestConnection): This permission is used to test endpoint connectivity, but it is not essential for creating a replication task; the missing permission is for creating endpoints.

Option B (s3:ListBucket): While s3:ListBucket might be useful for browsing S3 objects, it is not strictly required because DMS can access objects by key if the path is provided.

Option C (rds:ModifyDBInstance): This permission is not needed for DMS to perform migration; DMS uses the RDS instance as a target but does not require modification rights.

Option D (dms:CreateEndpoint): Correct. Without this permission, the user cannot create the source or target endpoints, which are prerequisites for running a DMS task.

A company is migrating a legacy on-premises application to AWS. The application requires static IP addresses for its clients to whitelist. The migration strategy includes using an Application Load Balancer (ALB) to distribute traffic across multiple EC2 instances in an Auto Scaling group. The clients require a fixed set of IP addresses to whitelist. Which solution meets the requirement?

A.Use AWS Global Accelerator with the Application Load Balancer as an endpoint.

B.Use an Application Load Balancer and assign Elastic IP addresses to it.

C.Use a Network Load Balancer with Elastic IP addresses.

D.Launch EC2 instances with Elastic IPs and place them behind a NAT Gateway.

AnswerC

NLB supports static IP addresses via Elastic IPs, meeting the whitelisting requirement.

Why this answer

A Network Load Balancer (NLB) supports static IP addresses via Elastic IP (EIP) assignment per Availability Zone, which allows clients to whitelist a fixed set of IPs. The ALB, by contrast, does not support static IP assignment; its DNS name resolves to dynamic IPs that can change. Using an NLB with EIPs meets the requirement for a fixed whitelist while still distributing traffic to the ALB or directly to EC2 instances.

Exam trap

The trap here is that candidates assume an Application Load Balancer can be assigned Elastic IPs because they are familiar with assigning EIPs to EC2 instances, but ALBs do not support static IP assignment at all, making the NLB the only correct choice for fixed whitelist IPs.

How to eliminate wrong answers

Option A is wrong because AWS Global Accelerator provides two static IP addresses but is an overlay service that still requires an endpoint (like an ALB or NLB) to receive traffic; it does not replace the need for a load balancer with static IPs, and the ALB itself still lacks static IPs. Option B is wrong because an Application Load Balancer cannot be assigned Elastic IP addresses; ALBs are designed to be internet-facing via a DNS name with dynamic IPs, and attaching EIPs is not supported. Option D is wrong because launching EC2 instances with Elastic IPs and placing them behind a NAT Gateway does not provide a load-balanced, highly available frontend; the NAT Gateway is used for outbound traffic, not inbound, and the EIPs would be tied to individual instances, not a single whitelistable set.

A.Increase the bandwidth of the Direct Connect link.

B.Use AWS Site-to-Site VPN over the internet as an alternative.

C.Schedule the migration during off-peak hours to avoid high utilization.

D.Use AWS Snowball Edge to transfer the data physically.

Off-peak hours ensure minimal impact on production traffic.

Why this answer

The correct approach is to schedule the migration during off-peak hours when the link utilization is lower to avoid congestion. Increasing bandwidth may not be feasible immediately. Using VPN over the internet may add latency and security concerns.

Snowball is for large data volumes, but if the data volume is manageable, off-peak migration is simpler.

A.Use a t2.large instance for the DMS replication instance to reduce cost

B.Use Amazon S3 as an intermediate target for initial load

C.Provision a large EC2 instance for the DMS replication instance (e.g., x1e.32xlarge)

D.Enable Multi-AZ on the target RDS instance

E.Disable automatic backup retention on the target database

AnswersB, C

Using Amazon S3 as an intermediate target for the initial full load is a best practice for large databases, as it reduces load on the source and accelerates the initial transfer.

Why this answer

Options B and C are correct. Option B: Using Amazon S3 as an intermediate target for the initial full load helps reduce the load on the source and accelerates the initial data transfer, which is critical for a 5 TB database. Option C: Provisioning a large EC2 instance for the DMS replication instance (e.g., x1e.32xlarge) provides the necessary memory and compute to handle large data volumes and ongoing replication with minimal downtime.

Option D is incorrect because Amazon RDS does not support SAP HANA as a database engine; SAP HANA must be deployed on Amazon EC2, so Multi-AZ on RDS is not applicable. Option A is incorrect because a t2.large instance lacks sufficient resources for a 5 TB migration. Option E is incorrect because disabling backup retention is not a best practice during migration and could lead to data loss.

A company is migrating its SAP system from on-premises to AWS. The system uses a shared filesystem (NFS) for transport directories and logs. The company wants to use AWS storage services to provide a similar shared filesystem. Which storage solution is MOST appropriate for this migration?

A.Amazon EFS (Elastic File System)

B.Amazon S3 with a mount point via s3fs-fuse

C.Amazon FSx for Windows File Server

D.Amazon EBS with multi-attach enabled

AnswerA

EFS provides a scalable NFS filesystem that can be shared across multiple EC2 instances.

Why this answer

Amazon EFS provides a managed NFS filesystem that can be mounted by multiple EC2 instances, making it suitable for SAP transport directories that require shared POSIX/NFS access. Option B (Amazon S3 with a mount point via s3fs-fuse) is not ideal because S3 is object storage and s3fs-fuse does not provide full POSIX compliance or consistent NFS semantics, leading to performance and concurrency issues. Option C (Amazon FSx for Windows File Server) uses SMB protocol, not NFS, so it is not appropriate for SAP systems that expect NFS.

Option D (Amazon EBS with multi-attach enabled) allows attaching a single volume to multiple instances but is limited to a few instances, requires a cluster-aware filesystem, and is more complex to manage than EFS for shared filesystem use cases.

A company is migrating a SAP system to AWS and needs to ensure that the database migration from SAP ASE to Amazon Aurora is successful with minimal downtime. Which AWS service should be used?

A.AWS Snowball Edge

B.AWS Server Migration Service (SMS)

C.AWS DataSync

D.AWS Database Migration Service (DMS)

AnswerD

DMS supports heterogeneous migrations and ongoing replication.

Why this answer

AWS Database Migration Service (DMS) is the correct choice because it supports heterogeneous migrations from SAP ASE (Sybase) to Amazon Aurora with minimal downtime. DMS can continuously replicate ongoing changes from the source database to the target using change data capture (CDC), allowing the source system to remain operational during the migration and enabling a cutover with only a brief outage.

Exam trap

The trap here is that candidates may confuse AWS DMS with AWS DataSync, assuming DataSync can handle database migrations, but DataSync is strictly for file-based data transfers and lacks the heterogeneous database replication capabilities required for SAP ASE to Aurora.

How to eliminate wrong answers

Option A (AWS Snowball Edge) is wrong because it is a physical data transfer device designed for large-scale offline data migrations, not for live database replication with minimal downtime, and it cannot perform ongoing CDC from SAP ASE to Aurora. Option B (AWS Server Migration Service) is wrong because it is used for migrating on-premises virtual machines to AWS as AMIs, not for database-level migrations between different database engines. Option C (AWS DataSync) is wrong because it is optimized for moving large volumes of file data over the network (e.g., NFS/SMB shares) and does not support heterogeneous database replication or CDC for SAP ASE to Aurora.

B.Deploy two EC2 instances in different Availability Zones with a shared Amazon EFS filesystem and use Route53 health checks for failover

C.Use AWS Global Accelerator with a static IP

D.Deploy a single EC2 instance with a large EBS volume

AnswerB

This is the standard architecture for ASCS HA on AWS.

Why this answer

SAP ASCS high availability on AWS requires a cluster spanning two Availability Zones with a shared filesystem for /sapmnt and /usr/sap/trans. AWS does not support cluster-based floating IPs, so Route53 health checks are used for failover. Option B is correct: it uses two EC2 instances in different AZs with Amazon EFS (shared filesystem) and Route53 health checks for automatic failover.

Option A (Amazon RDS Multi-AZ) is for databases, not ASCS. Option C (AWS Global Accelerator) provides traffic routing and static IP but does not handle ASCS failover. Option D (single EC2) lacks high availability.

A team is migrating an Oracle database to Amazon RDS for MySQL using AWS DMS with ongoing replication (CDC). The initial load succeeded, but the CDC task fails with the error shown in the exhibit. The source Oracle database is on-premises. Which action should the team take to resolve the issue?

A.Configure binary logging on the target MySQL RDS instance.

B.Stop and restart the DMS task to clear the error.

C.Switch the target database to Amazon RDS for Oracle to maintain compatibility.

D.Connect to the source Oracle database and enable full supplemental logging by executing the command: ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS;

AnswerD

This command enables the required logging for CDC to work.

Why this answer

AWS DMS requires full supplemental logging on the source Oracle database to capture all column values for CDC (ongoing replication). Without it, DMS cannot reconstruct the complete row changes from the redo logs, causing the CDC task to fail. Enabling full supplemental logging with `ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS;` ensures that every column is logged, allowing DMS to replicate all changes correctly.

Exam trap

The trap here is that candidates often assume the issue is on the target side (e.g., binary logging) or that a simple restart will fix transient errors, but AWS DMS CDC failures from Oracle almost always point to missing supplemental logging on the source.

How to eliminate wrong answers

Option A is wrong because binary logging is a MySQL-specific feature for replication, and the target RDS for MySQL already has it enabled by default; the issue is on the source Oracle side, not the target. Option B is wrong because stopping and restarting the DMS task will not resolve the underlying missing supplemental logging; the error will recur immediately. Option C is wrong because switching the target to RDS for Oracle would avoid the supplemental logging requirement but is an unnecessary and costly workaround that does not fix the root cause; the migration to MySQL is the stated goal.

C.Latency and bandwidth requirements.

D.BGP routing configuration and failover.

E.IP address range for VPC subnets.

AnswersC, D

Direct Connect provides consistent latency and dedicated bandwidth.

Why this answer

The two most important factors for planning Direct Connect connectivity in an SAP migration are latency/bandwidth requirements (C) and BGP routing configuration with failover (D). SAP applications are highly sensitive to latency and require consistent throughput, so ensuring sufficient bandwidth and low latency is critical. BGP routing and failover mechanisms guarantee high availability and resilience by enabling automatic failover to backup connections.

Option A (VPC endpoints) is not a Direct Connect factor—endpoints provide private access to AWS services but are unrelated to Direct Connect planning.

A company is migrating a critical SAP HANA database to AWS and needs to ensure high availability. The SAP HANA system replication will be configured across two Availability Zones. Which AWS service should be used to automate the failover of the SAP HANA database?

A.Amazon Route 53

B.AWS CloudFormation

C.AWS Elastic Disaster Recovery (DRS)

D.AWS Backup

AnswerA

Correct. Route 53 with failover routing and health checks automates DNS-level failover, redirecting traffic to the standby SAP HANA instance when the primary fails.

Why this answer

Amazon Route 53 with failover routing policy and health checks can automate DNS-level failover by directing traffic to the healthy SAP HANA instance. Combined with SAP HANA System Replication across AZs, this provides automated database failover. Option B (AWS CloudFormation) provisions infrastructure but does not automate failover.

Option C (AWS Elastic Disaster Recovery) is designed for cross-region disaster recovery, not cross-AZ high availability. Option D (AWS Backup) handles scheduled backups, not real-time failover.

An organization is migrating a SAP ERP system to AWS. The system has a requirement for high availability for the SAP Central Services (ASCS) instance. Which architecture should be used to meet this requirement?

A.Deploy the ASCS on a single EC2 instance with a Multi-AZ RDS database.

B.Deploy two ASCS instances in different Availability Zones with a shared Amazon EFS or FSx for Windows File Server and a floating IP using Route 53.

C.Deploy two ASCS instances in different Availability Zones with an EBS volume attached to both.

D.Use an Application Load Balancer to distribute traffic between two ASCS instances.

AnswerB

Shared storage and floating IP meet ASCS HA requirements.

Why this answer

For high availability of SAP Central Services (ASCS), you need to deploy two ASCS instances in different Availability Zones with a shared filesystem (Amazon EFS or FSx for Windows File Server) and a floating IP mechanism. Option B correctly describes this architecture using Route 53 for the floating IP. Option A is incorrect because Multi-AZ RDS is for databases, not ASCS.

Option C is incorrect because an EBS volume cannot be attached to multiple EC2 instances simultaneously. Option D is incorrect because an Application Load Balancer does not support floating IPs and is not appropriate for ASCS.

A company is migrating a legacy SAP HANA database (version 1.0) to SAP HANA on Amazon EC2 (version 2.0) with minimal downtime. Which AWS service should be used for the migration?

A.Use SAP HANA System Replication to replicate the source database to an Amazon RDS for SAP HANA instance.

B.Use AWS Database Migration Service (DMS) with change data capture (CDC) from the source SAP HANA database.

C.Export the database to flat files, upload to Amazon S3, and restore using an RDS read replica.

D.Use AWS Schema Conversion Tool (SCT) to convert the schema and then use AWS Database Migration Service (DMS) for data replication.

AnswerB

AWS DMS supports SAP HANA as both source and target and can use CDC to minimize downtime during homogeneous migration. This option is correct.

Why this answer

AWS DMS supports homogeneous migrations for SAP HANA and can replicate data with minimal downtime using change data capture (CDC). Option B is correct because DMS can migrate data from SAP HANA 1.0 to SAP HANA 2.0 on EC2 with CDC to minimize downtime. Option A is incorrect because RDS does not support SAP HANA, and read replicas cannot be created from an on-premises source.

Option C is incorrect because exporting to flat files and restoring via an RDS read replica is not a valid procedure and would cause downtime. Option D is incorrect because SCT is for schema conversion between different database engines, but since both source and target are SAP HANA, no schema conversion is needed; DMS alone is sufficient.

A company is migrating its SAP landscape to AWS and has a requirement to use existing software licenses to reduce costs. Which AWS pricing model should be used?

A.Dedicated Hosts

B.Compute Savings Plans

C.Reserved Instances (RI)

D.Dedicated Instances

AnswerA

Dedicated Hosts allow per-socket/core licensing.

Why this answer

Dedicated Hosts provide visibility into the underlying physical cores and sockets, enabling you to bring your own existing SAP licenses (e.g., per-core or per-socket) to AWS and reduce costs. Option B (Compute Savings Plans) offers discounts on compute usage but does not support license management. Option C (Reserved Instances) provides capacity reservation and cost savings but does not allow use of your own licenses.

Option D (Dedicated Instances) offers instance isolation at the hardware level but does not expose the underlying physical server for license tracking.

A company is migrating a critical application to AWS and needs to ensure compliance with PCI DSS. The application handles credit card numbers. Which AWS service should be used to encrypt the data at rest?

A.Amazon S3 server-side encryption

B.AWS Key Management Service (KMS)

C.AWS CloudHSM

D.AWS Secrets Manager

AnswerC

CloudHSM provides dedicated hardware security modules meeting PCI DSS requirements.

Why this answer

AWS CloudHSM, is correct because it provides dedicated hardware security modules (HSMs) that are FIPS 140-2 Level 3 compliant, which is often required for PCI DSS compliance when handling credit card numbers. Option A (Amazon S3 server-side encryption) is incorrect because it is used for encrypting objects in S3 and does not provide dedicated HSM capabilities. Option B (AWS KMS) is a managed key service but is FIPS 140-2 Level 2 only, which may not meet the stringent requirements of PCI DSS for protecting cardholder data.

Option D (AWS Secrets Manager) is incorrect because it manages secrets such as database credentials, not encryption keys for data at rest.

A company is migrating an SAP ERP system to AWS using the SAP Landscape Virtualization Management (LVM) tool. During the migration, the team encounters a timeout error when replicating the database. The source database is an SAP HANA multi-tenant database container (MDC) system. What is the most likely cause of the timeout?

A.The SAP Landscape Virtualization Management (LVM) agent is incompatible with the SAP HANA version

B.The SAP HANA multi-tenant database container (MDC) configuration is not supported by LVM

C.The SSH session between LVM and the target server timed out due to a missing ServerAliveInterval setting

D.The SAP Router is not configured to forward traffic between the source and target

AnswerC

LVM uses SSH; without keep-alive settings, idle SSH sessions can timeout during long-running operations.

Why this answer

LVM uses SSH to communicate between the source and target servers. If the SSH session times out due to inactivity (e.g., a missing ServerAliveInterval setting in the SSH client configuration), the database replication process can fail with a timeout error. Option A is incorrect because the LVM agent's compatibility with the SAP HANA version is not the typical cause of a replication timeout; such version compatibility issues would likely surface earlier during configuration.

Option B is incorrect because SAP HANA MDC (multi-tenant database container) is supported by LVM for migration; LVM can handle MDC systems properly. Option D is incorrect because the SAP Router is used for routing between SAP systems over a network, not for the direct SSH-based replication between source and target in an LVM migration; the timeout is due to SSH, not router misconfiguration.

Which TWO AWS services can be used to automate the deployment of SAP infrastructure during migration? (Choose 2.)

Select 2 answers

A.AWS OpsWorks

B.AWS Service Catalog

C.AWS CloudFormation

D.AWS Elastic Beanstalk

E.AWS CodePipeline

AnswersB, C

AWS Service Catalog allows organizations to create and manage a catalog of approved IT services, including standardized SAP infrastructure templates, enabling automated and compliant deployment.

Why this answer

AWS CloudFormation allows you to model and provision SAP infrastructure as code using templates. Option B is correct because AWS Service Catalog allows you to create and manage a catalog of approved IT services, including SAP infrastructure templates, which can be deployed in a standardized and automated manner. Option D is wrong because AWS Elastic Beanstalk is a PaaS service that abstracts the underlying OS and is not designed for the specific requirements of SAP deployments, such as kernel patching and custom system configurations.

Option A is wrong because AWS OpsWorks uses Chef/Puppet and is not typically used for SAP deployment automation. Option E is wrong because AWS CodePipeline is a CI/CD service, not for infrastructure deployment. So correct answers: B and C.

Refer to the exhibit. An administrator is setting up a migration from on-premises VMware VMs to AWS using AWS Server Migration Service (SMS). The IAM policy shown is attached to the SMS service role. The migration fails with an error indicating insufficient permissions. Which additional permission is required for SMS to successfully replicate VMs?

A.ec2:DeleteSnapshot

B.ec2:ImportImage

C.ec2:DescribeRegions

D.ec2:CreateSnapshot

AnswerB

SMS uses ImportImage to import VMs as EC2 instances.

Why this answer

The correct additional permission is ec2:ImportImage (Option B). AWS SMS uses this action to import a VM from on-premises as an Amazon Machine Image (AMI) in EC2. The IAM policy in the exhibit likely includes actions such as ec2:CreateSnapshot (needed for replication) but is missing ec2:ImportImage, which is explicitly required for the final import step.

Option A (ec2:DeleteSnapshot) is not needed because SMS does not delete snapshots as part of the replication process. Option C (ec2:DescribeRegions) is a read-only action and is not required for the import. Option D (ec2:CreateSnapshot) is typically already included in the SMS service role, so the error is not due to its absence.

A company is migrating its SAP ERP system to AWS and needs to retain the same SAP system ID (SID) and hostnames. The migration must be completed with minimal downtime. Which AWS service or feature supports this requirement?

A.SAP Software Update Manager (SUM) with Database Migration Option (DMO)

B.AWS CloudEndure Migration (now AWS Application Migration Service)

C.AWS Application Migration Service (MGN) with custom scripts

D.AWS Database Migration Service (DMS)

AnswerA

SUM with DMO can migrate the entire SAP system while preserving SID and hostnames.

Why this answer

SAP Software Update Manager (SUM) with Database Migration Option (DMO). SUM with DMO is an SAP tool specifically designed for system migrations, including cross-platform migrations like on-premises to AWS. It preserves the SAP system ID (SID) and hostnames by performing a homogeneous or heterogeneous migration while keeping the application configuration intact. It supports minimal downtime through near-zero downtime techniques.

Option B (AWS CloudEndure Migration, now AWS Application Migration Service) is a general-purpose migration service that replicates entire servers at the block level. While it can preserve hostnames and SIDs if configured, it is not SAP-aware and does not optimize for SAP system consistency or offer the same integration as SUM with DMO. It may require additional steps to ensure SAP-specific components are migrated correctly.

Option C (AWS Application Migration Service with custom scripts) similarly lacks SAP-specific tools and would rely on manual scripting to preserve SID and hostnames, increasing complexity and risk.

Option D (AWS Database Migration Service) is for database-level migration only and does not migrate the SAP application layer, so it cannot preserve the SID or hostnames of the entire SAP system.

A company is migrating a large SAP HANA database to AWS. They want to use SAP HANA Backup and Recovery with AWS storage. Which THREE options can be used as backup targets? (Choose THREE.)

Select 3 answers

A.Amazon S3

B.Amazon EFS

C.Amazon FSx for NetApp ONTAP

D.Amazon EBS volumes

E.Amazon S3 Glacier

AnswersA, C, D

S3 is a supported backup target using SAP HANA backup to S3.

Why this answer

SAP HANA backups can be stored on Amazon S3 (Option A) as a backup target using Backint, on Amazon FSx for NetApp ONTAP (Option C) as a file system mount, and on Amazon EBS volumes (Option D) attached to the HANA instance. Option B (Amazon EFS) is not supported as a backup target because SAP HANA requires block storage or specific file system features like snapshots that EFS does not provide. Option E (Amazon S3 Glacier) is not directly supported; while S3 is correct, Glacier is a cold storage class not suitable for direct backup targets.

A company is migrating SAP applications to AWS and uses the CloudFormation template snippet shown in the exhibit. The SAP ASCS instance requires a shared file system for the transport directory. However, the template does not create any shared storage. Which AWS resource should be added to the template to provide a shared file system?

A.Amazon EFS file system

B.Instance Store

C.Additional Amazon EBS volume

D.Amazon S3 bucket

AnswerA

Provides shared file system for multiple instances.

Why this answer

Amazon EFS provides a scalable, shared file system that can be mounted across multiple EC2 instances, making it suitable for the SAP transport directory. Option C (Additional EBS volume) is block storage that can only be attached to a single instance, not shared. Option D (Amazon S3 bucket) is object storage, not a file system.

Option B (Instance Store) is ephemeral and not shared.

A company is migrating an SAP system to AWS and wants to use an existing AWS Direct Connect connection for data transfer. The migration involves transferring 10 TB of data. Which AWS service is designed to accelerate data transfer over Direct Connect?

A.Amazon S3 Transfer Acceleration

B.AWS VPN

C.AWS DataSync

D.AWS Snowball

AnswerC

DataSync uses a purpose-built protocol to accelerate transfers over Direct Connect.

Why this answer

AWS DataSync is designed to accelerate data transfer over Direct Connect by optimizing network usage, performing automatic encryption, and managing retries. Amazon S3 Transfer Acceleration (Option A) is optimized for transfers over the internet using AWS edge locations, not Direct Connect. AWS VPN (Option B) provides a secure tunnel but does not accelerate bulk transfers.

AWS Snowball (Option D) is an offline physical device, not for use with Direct Connect.

A company is migrating a legacy on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB and has a 1-hour maintenance window. The company needs to minimize downtime and ensure data consistency. Which migration strategy should be used?

A.Use AWS Database Migration Service (AWS DMS) with ongoing replication from the source to the target.

B.Use Oracle Data Pump to export and import the database during the maintenance window.

C.Use AWS Schema Conversion Tool (AWS SCT) to convert the schema and then copy data manually.

D.Export the database to flat files, upload to Amazon S3, and then import into RDS.

AnswerA

AWS DMS with CDC minimizes downtime by replicating changes continuously.

Why this answer

AWS DMS with ongoing replication minimizes downtime by continuously replicating changes from the source to the target, allowing a cutover with minimal downtime. Native Oracle tools (Data Pump) or exporting to flat files require significant downtime, and AWS SCT only handles schema conversion.

Which TWO methods can be used to migrate an SAP system from on-premises to AWS while minimizing the need for re-architecture? (Choose two.)

Select 2 answers

A.Replatform by moving to Amazon RDS for SAP

B.Rehost by manually copying servers to Amazon EC2

C.Rehost using AWS Application Migration Service (AWS MGN)

D.Refactor the application to use microservices

E.Use AWS Database Migration Service to move the database to Amazon Aurora

AnswersB, C

Manual rehost also minimizes changes, though less automated.

Why this answer

Lift-and-shift (rehost) using AWS Application Migration Service and the 7-Migration Strategies (7Rs) rehost approach minimize re-architecture. Option A is wrong because replatforming involves some changes. Option D is wrong because refactoring involves significant re-architecture.

Option E is wrong because AWS DMS is for databases, not full systems.

A company is migrating SAP HANA to AWS and needs to ensure that the database instances have high network throughput for replication traffic. Which THREE AWS features should be enabled? (Choose THREE.)

Select 3 answers

A.Placement Groups

B.EBS-optimized instances

C.Enhanced Networking (SR-IOV)

D.Elastic IP addresses

E.VPC peering connections

AnswersA, B, C

Placement Groups, specifically the cluster placement group type, place SAP HANA instances in a low-latency, high-bandwidth logical group within a single Availability Zone. This satisfies the requirement for high network throughput for replication traffic by ensuring instances are physically close, minimising network hops and maximising throughput for SAP HANA’s log replication and data synchronisation.

Why this answer

Enhanced Networking provides higher network performance, Placement Groups provide low-latency network, and EBS-optimized instances provide dedicated bandwidth to EBS. Option D is wrong because Elastic IP does not improve throughput. Option E is wrong because VPC peering does not improve throughput, it connects VPCs.

A company is migrating a critical application to AWS using a phased approach. The application uses a custom Linux distribution that is not supported by AWS Application Migration Service. Which THREE steps should the company take to migrate the application? (Choose THREE)

Select 3 answers

A.Use AWS Server Migration Service (SMS) to replicate the on-premises server to AWS.

B.Convert the application to run on Amazon Linux 2 to simplify future management.

C.Perform a test migration to a non-production environment to validate the application.

D.Use AWS Database Migration Service (DMS) to migrate the application server.

E.Create a custom Amazon Machine Image (AMI) with the required Linux distribution and dependencies.

AnswersA, C, E

SMS can replicate servers even if the OS is not officially supported by AWS MGN.

Why this answer

AWS Server Migration Service (SMS) is the correct choice because it is an agentless service that can replicate on-premises servers running custom Linux distributions as long as they are supported by the underlying hypervisor. SMS uses incremental replication to create Amazon Machine Images (AMIs) from the source server, enabling a lift-and-shift migration without requiring the application to be converted to a different OS. This approach directly addresses the scenario where AWS Application Migration Service does not support the custom Linux distribution.

Exam trap

The trap here is that candidates often confuse AWS DMS as a general-purpose migration tool for servers, when in fact it is strictly for database migrations, leading them to incorrectly select Option D instead of recognizing that server migration requires a dedicated replication service like SMS or a custom AMI approach.

A company plans to migrate a 10 TB on-premises SQL Server database to Amazon RDS for SQL Server. The migration must be completed within a 4-hour window. The network bandwidth is 1 Gbps. Which migration approach should they choose?

A.Use AWS SCT to convert schema and then export/import via native tools

B.Use AWS DMS over the internet

C.Set up an AWS Direct Connect connection and use DMS

D.Use AWS Snowball Edge to transfer data and then perform a cutover

AnswerD

AWS Snowball Edge physically ships the data, avoiding network transfer time. The cutover can be performed within the 4-hour window after the data is loaded to Amazon RDS.

Why this answer

AWS SCT only converts schema, not data; export/import via native tools would still need to transfer the full 10 TB over the internet, which at 1 Gbps takes ~22 hours, far exceeding the 4-hour window. Option B is incorrect because DMS over the internet is limited by the 1 Gbps bandwidth, resulting in a transfer time of ~22 hours, too slow. Option C is incorrect because while Direct Connect provides a dedicated connection, it still has a 1 Gbps bandwidth limit, so the transfer would still take ~22 hours, exceeding the window.

Option D is correct because AWS Snowball Edge physically ships the data, bypassing network bandwidth limitations, and allows a fast cutover.

A company is migrating an SAP HANA database to AWS using AWS DMS. An IAM policy has been created for the DMS service role as shown in the exhibit. The migration fails with an error that the DMS task cannot access the source database. Which additional permission is most likely required?

A.dms:DescribeEndpoints and dms:CreateEndpoint

B.kms:Decrypt

C.rds:DescribeDBInstances

D.ec2:DescribeSubnets

AnswerA

DMS needs permissions to manage endpoints.

Why this answer

The policy allows DMS actions and S3 bucket access, but does not include permissions for source database endpoints (e.g., RDS or EC2). DMS needs permissions to describe and connect to the source. kms:Decrypt is not relevant unless encryption is used. ec2:DescribeSubnets is for network settings.

A company is planning to migrate its SAP environment to AWS. They have multiple SAP systems that are interconnected. Which migration approach is recommended to minimize dependency issues?

A.Migrate systems based on business process priority, ignoring technical dependencies

B.Migrate systems in logical groups that have dependencies on each other

C.Migrate systems individually based on size, starting with the smallest

D.Migrate all systems at the same time in a big bang approach

AnswerB

Grouping dependent systems ensures they are migrated together, preserving connections.

Why this answer

When migrating interconnected SAP systems, the recommended approach is to migrate them in logical groups based on dependencies. This ensures that dependent systems are moved together, minimizing issues with integrations, interfaces, and data consistency. Option A is incorrect because ignoring technical dependencies can lead to broken integrations.

Option C is incorrect because migrating by size may break dependencies across systems. Option D is incorrect because a big bang migration of all systems simultaneously is highly risky and complex.
