A company is migrating a file server to AWS and needs a scalable, highly available file storage solution that supports the SMB protocol. Which AWS service should be used?

A.Amazon Elastic File System (EFS)
B.AWS Storage Gateway
C.Amazon Simple Storage Service (S3)
D.Amazon FSx for Windows File Server
AnswerD

Supports SMB protocol.

Why this answer

Amazon FSx for Windows File Server supports SMB protocol and provides fully managed Windows file servers. Option A (Amazon EFS) supports NFS, not SMB. Option B (Amazon S3) is object storage.

Option D (AWS Storage Gateway) can present file shares but is not a fully managed file server.

MCQeasy

A company is migrating a fleet of 200 on-premises Windows servers to AWS. The servers run a mix of custom applications and Microsoft SQL Server databases. The migration plan includes using AWS Server Migration Service (SMS) for the servers and AWS Database Migration Service (DMS) for the databases. During the initial replication, several servers fail with the error 'Unable to create AMI: Insufficient permissions'. The IAM role used by SMS has the following policy: {"Version":"2012-10-17","Statement":[{"Effect":"Allow","Action":["ec2:Describe*","ec2:CreateImage","ec2:RegisterImage","s3:PutObject","s3:GetObject","s3:ListBucket"],"Resource":"*"}]}. Which change should be made to resolve the error?

A.Remove the s3:PutObject action from the policy
B.Configure a VPC endpoint for EC2
C.Add ec2:CreateSnapshot action to the policy
D.Add ec2:ImportImage action to the policy
AnswerC

SMS requires CreateSnapshot to create snapshots before creating AMIs.

Why this answer

SMS requires the ec2:CreateSnapshot permission to create snapshots of volumes before creating AMIs. The error 'Unable to create AMI: Insufficient permissions' indicates that this permission is missing from the IAM policy. Option A is incorrect because removing s3:PutObject would not resolve the error; the issue is about EC2 permissions, not S3.

Option B is incorrect because the error is not related to network connectivity; a VPC endpoint for EC2 would not grant the necessary permissions. Option D is incorrect because ec2:ImportImage is used for importing virtual machine images, not for creating AMIs from existing instances via SMS.

An organization is migrating an SAP system from on-premises to AWS. The SAP system uses a shared file system (NFS) for transport directories. The company wants a fully managed NFS solution on AWS. Which service should they use?

A.Amazon Elastic Block Store (EBS)
B.Amazon FSx for Windows File Server
C.Amazon Elastic File System (EFS)
D.Amazon S3
AnswerC

Managed NFS file system.

Why this answer

Amazon EFS is a fully managed NFS file system that supports the NFSv4.1 and NFSv4.0 protocols, making it the ideal choice for SAP transport directories that require a shared POSIX-compliant file system. It provides high availability, automatic scaling, and eliminates the need to manage underlying storage infrastructure, directly matching the requirement for a fully managed NFS solution on AWS.

Exam trap

The trap here is that candidates often confuse Amazon EBS with a shared file system because it can be formatted with a file system, but they overlook that EBS volumes cannot be attached to multiple EC2 instances simultaneously without additional clustering software, making it unsuitable for NFS-based SAP transport directories.

How to eliminate wrong answers

Option A is wrong because Amazon EBS provides block-level storage volumes that can be attached to a single EC2 instance at a time; it does not natively support NFS or multi-instance shared access without additional configuration (e.g., using a cluster file system). Option B is wrong because Amazon FSx for Windows File Server uses the SMB protocol, not NFS, and is designed for Windows-based workloads, not for SAP transport directories that require NFS. Option D is wrong because Amazon S3 is an object storage service accessed via HTTP/HTTPS APIs, not a file system with NFS protocol support, and does not provide the POSIX file system semantics required by SAP.

A company is migrating an SAP S/4HANA system to AWS. The system requires high availability for the database and application layers. Which THREE components should the company configure to achieve high availability for SAP S/4HANA on AWS?

Select 3 answers
A.Pacemaker cluster for SAP Central Services
B.Multi-AZ deployment for SAP HANA database
C.Single Availability Zone deployment
D.Amazon EFS for SAP transport directory
E.AWS Transit Gateway
AnswersA, B, D

Pacemaker manages failover.

Why this answer

To achieve high availability for SAP S/4HANA on AWS, three components are required. A Pacemaker cluster (option A) manages SAP Central Services (ASCS and ERS) by automating failover. Multi-AZ deployment for SAP HANA (option B) ensures database high availability by replicating across Availability Zones.

Amazon EFS (option D) provides a shared file system for the SAP transport directory, essential for consistent failover. Option C (Single Availability Zone) lacks redundancy, and option E (AWS Transit Gateway) is a networking component unrelated to high availability.

MCQhard

A company is migrating its SAP NetWeaver system from on-premises to AWS. The system uses a central instance (ASCS) and multiple dialog instances. The migration must be completed with minimal downtime. Which approach should the company use?

A.Use SAP Software Provisioning Manager (SWPM) to perform a system copy into pre-provisioned EC2 instances with the same sizing.
B.Use AWS CloudEndure Migration to continuously replicate the SAP system.
C.Uninstall SAP from on-premises and perform a fresh installation on AWS, then restore the database backup.
D.Use AWS Application Migration Service (AWS MGN) to replicate the entire on-premises system to AWS.
AnswerA

SWPM system copy is an SAP-certified method for migrating with minimal downtime.

Why this answer

Using SAP Software Provisioning Manager (SWPM) to perform a system copy into pre-provisioned EC2 instances with the same sizing allows for a controlled, minimal-downtime migration. SWPM handles SAP-specific consistency, enabling a homogeneous system copy that can be completed with minimal downtime by pre-loading data and then applying incremental changes. Option B is wrong because AWS CloudEndure Migration (replaced by AWS Application Migration Service) replicates at the block level, which may not maintain SAP application consistency without additional steps.

Option C is wrong because uninstalling and performing a fresh installation requires significant downtime and reconfiguration. Option D is wrong because AWS Application Migration Service replicates at the block level and may not handle SAP application consistency optimally, potentially requiring additional validation and downtime.

A company is migrating an SAP Business Suite system to AWS. The source database is Oracle. The target is Amazon RDS for Oracle. Which AWS service should be used to automate the schema conversion and data migration?

A.AWS Schema Conversion Tool (SCT)
B.Both AWS SCT and AWS DMS
C.AWS Application Discovery Service
D.AWS Database Migration Service (DMS)
AnswerB

SCT for schema conversion and DMS for data migration.

Why this answer

Schema conversion is handled by AWS Schema Conversion Tool (SCT) and data migration with minimal downtime is handled by AWS Database Migration Service (DMS). Option A is wrong because SCT alone does not migrate data. Option C is wrong because AWS Application Discovery Service is used for discovery, not migration.

Option D is wrong because DMS alone does not convert schemas.

MCQhard

A company is migrating an SAP S/4HANA system to AWS. The system uses SAP HANA as its database. The company has a complex networking setup with multiple VPCs and on-premises connectivity via AWS Direct Connect. The SAP HANA system replication will be used for high availability across two Availability Zones. What is the minimum number of Elastic Network Interfaces (ENIs) required per HANA instance to support the recommended network architecture?

A.2
B.1
AnswerA

Correct: The recommended minimum is 2 ENIs to separate client and replication traffic.

Why this answer

The minimum number of ENIs recommended for SAP HANA system replication across Availability Zones is 2. This allows separation of client traffic from HANA system replication traffic, which is a best practice. A single ENI can technically carry all traffic but does not adhere to the recommended network architecture.

Option A (2) is the minimum, while Option B (1) is insufficient.

Which TWO AWS services can be used to migrate an on-premises SAP HANA database to AWS with minimal downtime? (Choose 2.)

Select 2 answers
A.SAP Landscape Transformation (SLT)
B.AWS Backup
C.AWS Database Migration Service (DMS)
D.AWS CloudEndure Migration
E.SAP HANA System Replication (HSR)
AnswersA, E

SLT can replicate data in real-time from HANA to HANA.

Why this answer

(SAP Landscape Transformation) is correct because SLT can replicate data in real-time from an on-premises SAP system to SAP HANA on AWS, enabling minimal downtime migration. Option E (SAP HANA System Replication) is correct because HSR provides native, continuous database replication with automatic failover, allowing migration with minimal downtime. Options B (AWS Backup), C (AWS DMS), and D (CloudEndure) are incorrect: AWS Backup is for backup/restore, not continuous replication; DMS does not support SAP HANA as a source; CloudEndure is not recommended for SAP HANA workloads.

A company is migrating its SAP ERP system to AWS. The system uses an SAP HANA database and runs on SUSE Linux Enterprise Server (SLES). The company wants to use the same SLES version on AWS and needs to ensure that the instance type supports the required SAP HANA workload. Which AWS resource should the administrator use to find the appropriate instance types?

A.The AWS Well-Architected Framework documentation.
B.The SAP Certified and Supported SAP HANA Hardware Directory on the SAP website.
C.The SAP on AWS Implementation Guide.
D.The AWS Trusted Advisor console.
AnswerB

This directory lists certified hardware including AWS instances.

Why this answer

The SAP Certified and Supported SAP HANA Hardware Directory is the authoritative source that lists all AWS instance types certified for SAP HANA. The administrator can filter by provider (Amazon Web Services), OS (SUSE Linux Enterprise Server), and instance type to find supported options. Option A (AWS Well-Architected Framework) provides general guidance but not certified hardware lists.

Option C (SAP on AWS Implementation Guide) offers deployment guidance but not the exhaustive hardware directory. Option D (AWS Trusted Advisor) checks best practices and cost optimization but does not provide SAP HANA certification details.

A company is migrating an SAP environment to AWS and needs to ensure that the SAP HANA database can be backed up efficiently. Which THREE AWS services can be used together to implement a backup strategy for SAP HANA?

Select 3 answers
A.Amazon RDS
B.Amazon EBS snapshots
C.Amazon DynamoDB
D.AWS Backup
E.Amazon S3
AnswersB, D, E

EBS snapshots provide quick backups of HANA volumes.

Why this answer

The correct answers are B, D, and E. Amazon EBS snapshots provide point-in-time backups of SAP HANA data volumes. AWS Backup can automate and manage backup schedules for EBS snapshots and other resources.

Amazon S3 can be used for long-term storage of backup files. Option A (Amazon RDS) is incorrect because SAP HANA is not an RDS database; it runs on EC2 with EBS volumes. Option C (Amazon DynamoDB) is a NoSQL database not used for SAP HANA backups.

A company is planning to migrate an SAP HANA database to AWS. Which THREE factors should the company consider when selecting an EC2 instance type for the SAP HANA database?

Select 3 answers
A.The instance type must support burstable performance
B.The instance must be EBS-optimized
C.The instance must be based on the AWS Nitro System
D.The instance type must be memory-optimized (e.g., r5, r6i, x1e)
E.The instance type must be listed in the SAP Certified Instance Types for SAP HANA
AnswersB, D, E

Correct. EBS-optimized instances are required for dedicated EBS bandwidth to ensure consistent I/O performance for HANA data volumes.

Why this answer

For SAP HANA on AWS, EC2 instance types must be memory-optimized (e.g., r5, r6i, x1e) and listed in the SAP Certified Instance Types for SAP HANA. Additionally, instances must be EBS-optimized to provide dedicated bandwidth to EBS volumes. Burstable performance (option A) is not suitable for SAP HANA's consistent performance requirements.

While the Nitro System (option C) is recommended, it is not a strict requirement.

Exam trap

Avoid choosing 'burstable performance' or 'Nitro System' as strict requirements. The key mandatory factors are EBS-optimized, memory-optimized, and SAP-certified.

MCQeasy

A company is migrating a SAP system to AWS and wants to use the same SAP system ID (SID) as on-premises. What is a prerequisite for this migration?

A.The SID must be changed to a new value for the migration.
B.The SID must be at least 5 characters long.
C.The SID must be registered with AWS.
D.The SID must be unique within the AWS account and region.
AnswerD

Duplicate SIDs are not allowed.

Why this answer

SAP requires that the System ID (SID) be unique within an AWS account and region to avoid conflicts with existing SAP systems. During migration, the same SID can be reused as long as no other SAP system with that SID exists in the same account and region, ensuring proper system identification and integration with AWS services like Amazon EFS or Amazon FSx for SAP.

Exam trap

The trap here is that candidates may assume the SID must be changed or registered with AWS, but the actual prerequisite is uniqueness within the AWS account and region, not a global or external registration.

How to eliminate wrong answers

Option A is wrong because the SID does not need to be changed; it can remain the same as on-premises, provided it is unique in the target AWS account and region. Option B is wrong because SAP SIDs are always exactly 3 characters long, not at least 5; this is a fixed length defined by SAP standards. Option C is wrong because there is no requirement to register the SID with AWS; AWS does not maintain a registry of SAP SIDs, and the uniqueness constraint is managed within the customer's account.

A.Amazon QuickSight
B.Amazon EMR
C.Amazon Redshift
D.Amazon RDS
AnswerA

Amazon QuickSight is a managed BI service suitable for replacing SAP BusinessObjects.

Why this answer

Amazon QuickSight is a fully managed business analytics service that can replace SAP BusinessObjects for reporting and dashboards, reducing operational overhead. Option A (QuickSight) is correct. Option B (EMR) is for big data processing.

Option C (Redshift) is a data warehouse. Option D (RDS) is a relational database service.

A company is using this CloudFormation template to provision infrastructure for an SAP HANA migration. When the stack is created, the RDS instance fails to launch. What is the most likely reason?

A.The InstanceType parameter is not properly referenced.
B.The DBInstanceClass db.x1e.2xlarge is not valid.
C.The AMI ID is invalid.
D.Amazon RDS does not support the SAP HANA engine.
AnswerD

SAP HANA is not available as an RDS engine; it must be deployed on EC2.

Why this answer

Amazon RDS does not support SAP HANA as a database engine. SAP HANA must be installed on EC2 instances or on bare metal. Option A is incorrect because the template references the InstanceType parameter correctly using the Ref function.

Option B is incorrect because while db.x1e.2xlarge is a valid RDS instance class for some engines (e.g., SQL Server), it is not valid for a non-existent RDS engine; but the primary issue is that SAP HANA is not supported on RDS at all. Option C is incorrect because the AMI ID is not relevant; RDS does not use AMIs; the stack would fail before checking AMI.

A company is migrating SAP applications to AWS and needs to replicate data from on-premises Active Directory to AWS Managed Microsoft AD for authentication. Which AWS service should be used?

A.AWS Transit Gateway
B.AWS Directory Service for Microsoft Active Directory
C.AWS Resource Access Manager (RAM)
D.AWS AD Connector
AnswerB

AWS Directory Service for Microsoft Active Directory is a managed service that can be set up with a trust relationship to on-premises AD, allowing replication of directory objects, meeting the requirement.

Why this answer

AWS Directory Service for Microsoft Active Directory is the correct service because it provides a managed Active Directory in AWS that can be configured with a forest trust to on-premises Active Directory, enabling replication of directory data. This allows authentication using on-premises credentials in AWS. Option A (AWS Transit Gateway) is for network connectivity, not directory replication.

Option C (AWS Resource Access Manager) is used for sharing resources across accounts. Option D (AWS AD Connector) only proxies authentication requests and does not replicate data. Therefore, the best answer is AWS Directory Service for Microsoft Active Directory.

An administrator is migrating an on-premises application to AWS. The application stores persistent data on a separate disk. The administrator launched an EC2 instance as a test and attached an additional EBS volume for the persistent data. The above exhibit shows the block device mapping for the test instance. Later, the administrator terminates the test instance, but the persistent data must be retained. However, after termination, the persistent data volume is also deleted. What is the most likely cause?

A.The instance was stopped instead of terminated, and the persistent data volume was detached during the stop.
B.The persistent data volume (vol-0f1e2d3c4b5a67890) had DeleteOnTermination set to false, but the administrator inadvertently changed it before termination.
C.The administrator mistakenly stored the persistent data on the root volume (vol-0a1b2c3d4e5f67890), which has DeleteOnTermination set to true.
D.The persistent data volume was not properly attached to the instance before termination.
AnswerC

If the persistent data was on the root volume, it would be deleted when the instance is terminated because DeleteOnTermination is true.

Why this answer

The exhibit shows the root volume (vol-0a1b2c3d4e5f67890) as the only volume with DeleteOnTermination set to true. The administrator intended to store persistent data on a separate EBS volume, but the data was actually stored on the root volume. When the instance was terminated, the root volume was deleted due to its DeleteOnTermination flag being true, causing the loss of the persistent data.

Exam trap

The trap here is that candidates may assume the persistent data volume is the one with a different volume ID (vol-0f1e2d3c4b5a67890) and overlook the possibility that the data was actually stored on the root volume, which has DeleteOnTermination set to true by default.

How to eliminate wrong answers

Option A is wrong because stopping an instance does not delete any attached EBS volumes; it only halts the instance, and volumes remain attached unless explicitly detached. Option B is wrong because if the persistent data volume (vol-0f1e2d3c4b5a67890) had DeleteOnTermination set to false, it would not be deleted upon termination; changing it to true would require a deliberate action, and the question states the administrator did not intend to delete it. Option D is wrong because if the volume was not properly attached, the instance would not have been able to access the persistent data during the test, and the volume would not have been deleted upon termination—it would simply remain unattached.

A company is migrating a 10 TB SQL Server database to Amazon RDS for SQL Server using AWS DMS. The migration is taking longer than expected. Which TWO actions can improve the migration speed? (Choose two.)

Select 2 answers
A.Use a single DMS task with full LOB mode
B.Enable parallel loading by splitting tables into multiple tasks
C.Use S3 multipart upload for the data
D.Increase the DMS replication instance size
E.Disable transaction logging on the source
AnswersB, D

Parallel tasks utilize more resources and speed up data transfer.

Why this answer

Splitting tables into multiple DMS tasks enables parallel loading, which significantly reduces migration time by processing multiple tables concurrently. Option D is correct because increasing the DMS replication instance size provides more CPU and memory resources, allowing the instance to handle larger data volumes and higher throughput more efficiently.

Exam trap

The trap here is that candidates may think full LOB mode or disabling transaction logs speeds up migration, but these actions either add overhead or break DMS's ability to capture changes, while the correct answers focus on parallelism and resource scaling.

A company is migrating an SAP system from on-premises to AWS. The current system uses a dual-stack (IPv4 and IPv6) network. The company wants to ensure that the SAP system on AWS supports both IP versions. Which THREE actions should the company take? (Choose 3.)

Select 3 answers
A.Update security group rules to allow both IPv4 and IPv6 traffic
B.Assign both IPv4 and IPv6 addresses to the EC2 instances
C.Create an Egress-Only Internet Gateway
D.Configure the VPC to support dual-stack mode
E.Set up a NAT Gateway for IPv6 traffic
AnswersA, B, D

Correct: Security group rules must allow both IPv4 and IPv6 traffic for dual-stack support.

Why this answer

To support dual-stack (IPv4 and IPv6) on AWS, the VPC must be configured for dual-stack, EC2 instances must have both IPv4 and IPv6 addresses assigned, and security group rules must allow both IPv4 and IPv6 traffic. Option A (Update security group rules to allow both IPv4 and IPv6 traffic) is correct. Option B (Assign both IPv4 and IPv6 addresses to the EC2 instances) is correct.

Option D (Configure the VPC to support dual-stack mode) is correct. Option C (Create an Egress-Only Internet Gateway) is not required for dual-stack support; it's used for outbound-only IPv6 traffic. Option E (Set up a NAT Gateway for IPv6 traffic) is incorrect because NAT Gateways are for IPv4, not IPv6.

A company is migrating a 5 TB Oracle data warehouse to Amazon Redshift. They need to minimize downtime and ensure data consistency. Which migration approach should they use?

A.Export data using Oracle UNLOAD and COPY into Redshift
B.Use AWS DMS with ongoing replication and perform a cutover
C.Stream data using Amazon Kinesis and then load into Redshift
D.Use AWS SCT to convert schema and then manually copy data
AnswerB

DMS can replicate continuously and then apply final changes.

Why this answer

Using AWS DMS with ongoing replication and performing a cutover ensures data consistency and minimizes downtime during the migration. DMS replicates changes in real-time, allowing a final cutover with zero data loss. Option A (Oracle UNLOAD and COPY) requires significant downtime for export/import.

Option C (Amazon Kinesis) is for streaming, not bulk migration. Option D (AWS SCT for schema conversion) only handles schema, not data transfer.

A company is migrating its on-premises Oracle database to Amazon RDS for Oracle. They need to minimize downtime and ensure data consistency. Which AWS service should they use for the initial data load and ongoing replication?

A.AWS Snowball Edge
B.AWS Database Migration Service (DMS)
C.AWS DataSync
D.AWS Schema Conversion Tool (SCT)
AnswerB

Correct because DMS can perform full load and ongoing replication (CDC) to minimize downtime.

Why this answer

**Option A (AWS Snowball Edge):** Incorrect because Snowball Edge is designed for offline data transfer, not for ongoing replication with minimal downtime. It could be used for initial data load but does not support continuous replication.

**Option B (AWS DMS):** Correct. AWS Database Migration Service can perform a full load of the source Oracle database to Amazon RDS for Oracle and then continuously replicate changes using Change Data Capture (CDC) to minimize downtime and ensure consistency.

**Option C (AWS DataSync):** Incorrect because DataSync is used for file-based data transfers (e.g., NFS/SMB shares), not for database replication.

**Option D (AWS SCT):** Incorrect because the Schema Conversion Tool only converts database schemas and code; it does not handle data migration or replication.

An organization is migrating an SAP ECC system to AWS using SAP Software Provisioning Manager (SWPM) and a homogeneous system copy. They have already exported the source system and are now importing to the target. The import fails with an error indicating that the target database tablespace is full. What should the administrator do to resolve the issue?

A.Increase the allocated storage for the target database tablespace.
B.Reduce the size of the source export by excluding some data.
C.Restart the import with a smaller package size.
D.Use SAP DMO instead of SWPM for the migration.
AnswerA

This provides the necessary space to complete the import.

Why this answer

The correct solution is to increase the size of the database tablespace on the target RDS instance or EC2-based database. Restarting the import without fixing the space issue will fail again. Reducing source export size is not appropriate as it would lose data.

Using a different migration method is unnecessary.

An organization is migrating its SAP ERP system to AWS. The system uses SAP NetWeaver and a third-party backup tool that requires direct access to the database files. Which AWS storage option should be used for the database to ensure compatibility?

A.Amazon EFS
B.Amazon FSx for Windows File Server
C.Amazon EBS
D.Amazon S3
AnswerC

EBS provides block-level storage that can be accessed as a raw device.

Why this answer

(Amazon EBS) is correct because EBS provides block-level storage that can be mounted as a raw device, allowing backup tools to directly access database files. Option A (Amazon EFS) is wrong because EFS is a file storage service, not block-level. Option B (Amazon FSx for Windows File Server) is wrong because FSx for Windows is file storage for Windows workloads, not block-level.

A company is migrating an SAP system to AWS and needs to ensure that the SAP application can communicate with the database over a low-latency, high-bandwidth connection. What is the best practice for network architecture?

A.Place the SAP application on-premises and the database on AWS.
B.Place the SAP application and database in the same VPC and same Availability Zone.
C.Place the SAP application and database in separate Availability Zones within the same region.
D.Place the SAP application in a different AWS Region than the database.
AnswerB

Same AZ ensures low-latency communication.

An SAP system on AWS is experiencing high latency between the SAP application servers and the HANA database. The application servers are in a different Availability Zone than the database. Which change should a migration specialist recommend to reduce latency without increasing costs significantly?

A.Enable Enhanced Networking on all instances
B.Create a VPC Peering connection between the application and database subnets
C.Use larger instance types for the application servers
D.Deploy SAP application servers in the same placement group and Availability Zone as the HANA database
AnswerD

Same placement group and AZ minimizes network hops and latency.

Why this answer

Deploying SAP application servers in the same placement group and Availability Zone as the HANA database minimizes network distance and reduces latency without additional cost. Option A is incorrect: Enhanced Networking improves throughput and reduces packet loss but does not eliminate cross-AZ latency. Option B is incorrect: VPC Peering is used for inter-VPC connectivity, not for reducing latency within the same VPC.

Option C is incorrect: using larger instance types does not necessarily reduce network latency and would increase costs.

A company is migrating a 10 TB SAP HANA database to AWS. They have a limited time window and need to minimize migration time. The database is running on a physical server with 1 Gbps network link to AWS. Which migration strategy is MOST suitable?

A.Use AWS Direct Connect to increase bandwidth before migration
B.Use AWS Snowball Edge to transfer the database files offline
C.Use AWS SCT to convert the database and then use DMS
D.Use AWS DMS over the existing network link
AnswerB

Snowball Edge can transfer 10 TB quickly via physical shipment.

Why this answer

AWS Snowball Edge provides a high-capacity physical device for offline data transfer, avoiding network bandwidth limitations. Option A is wrong because AWS Direct Connect requires setup time and still is limited by 1 Gbps bandwidth, which would still result in long transfer times for 10 TB. Option C is wrong because AWS SCT is for schema conversion, not data transfer.

Option D is wrong because AWS DMS over a 1 Gbps link would take too long for 10 TB of data.

A.Replatform
B.Refactor
C.Repurchase
D.Rehost
AnswerD

Minimal changes, suitable for custom kernels.

Why this answer

Rehost (lift-and-shift) is appropriate when moving SAP systems with custom kernels, as it minimizes changes. Option A (Replatform) involves changes to the platform. Option B (Refactor) involves re-architecting.

MCQhard

A multinational corporation is migrating its SAP S/4HANA system to AWS. The system consists of a production database (3 TB), a development database (500 GB), and multiple application servers. The migration plan is to use AWS Database Migration Service (DMS) for the databases and AWS Application Migration Service (MGN) for the application servers. The company has set up a test environment in AWS and has performed a test migration. During the test, the production database migration via DMS completed successfully, but the development database migration failed with an error indicating that the source database version is not supported by DMS. The development database is SAP HANA 2.0 SPS 04, while the production database is SAP HANA 2.0 SPS 05. The target for both is Amazon RDS for SAP HANA. The DMS source endpoint was created using the same settings for both databases. Which step should the administrator take to resolve the development database migration failure?

A.Use SAP HANA System Replication to replicate the development database to RDS.
B.Upgrade the source development SAP HANA to a supported version (e.g., SPS 05).
C.Downgrade the production database to match the development version.
D.Use AWS Server Migration Service (SMS) for the development database.
AnswerB

DMS requires a supported source version.

Why this answer

DMS requires a supported SAP HANA version. The development database version (SPS 04) is not supported, so upgrading it to SPS 05 will allow the migration to proceed. Option A is incorrect because SAP HANA System Replication is not designed for migrating to RDS; it replicates between HANA instances.

Option C is incorrect because downgrading the production database is unnecessary and risky. Option D is incorrect because AWS SMS is for server migration, not database migration.

An organization is migrating an SAP BusinessObjects system to AWS. The system uses a Sybase ASE database. They need to minimize downtime. Which migration strategy is most appropriate?

A.Use AWS Database Migration Service (DMS) with ongoing replication.
B.Perform an export/import of the database to AWS.
C.Use SAP Landscape Reorganization (LaMa) to automate the migration.
D.Set up HANA System Replication (HSR) to the AWS target.
AnswerC

LaMa supports Sybase ASE and can automate the cutover with minimal downtime.

Why this answer

The best approach is to use SAP Landscape Reorganization (LaMa) which supports Sybase ASE and can automate the migration with minimal downtime. DMS does not support Sybase ASE as a source. HSR is for SAP HANA, not Sybase.

Export/import is manual and leads to longer downtime.

A company is migrating its SAP ERP system to AWS and needs to ensure that the SAP license is compliant. The company has a production license for SAP ERP. What should the company do for licensing on AWS?

A.Request a free SAP license for AWS from SAP.
B.Use a subscription-based SAP license from the AWS Marketplace.
C.Purchase a new SAP license for AWS.
D.Use the existing SAP license under the Bring Your Own License (BYOL) model.
AnswerD

BYOL allows using existing licenses on AWS.

Why this answer

AWS supports the Bring Your Own License (BYOL) model for SAP, allowing the company to use its existing SAP ERP license on AWS. Option A is incorrect because SAP does not offer a free license for AWS. Option B is incorrect because while subscription licenses are available, the company already has a production license, so BYOL is the appropriate choice.

Option C is incorrect because purchasing a new license is unnecessary when the existing license can be reused under BYOL.

A company needs to migrate its SAP application server from on-premises to AWS. The server runs on Windows Server 2012 R2 and has a custom SAP kernel. Which AWS service should be used to migrate the server with minimal changes?

A.AWS CloudEndure Migration
B.AWS Database Migration Service (AWS DMS)
C.AWS Application Migration Service (AWS MGN)
D.AWS Server Migration Service (AWS SMS)
AnswerC

AWS Application Migration Service (MGN) automates lift-and-shift server migrations, supporting Windows and custom SAP kernels.

Why this answer

AWS Application Migration Service (AWS MGN) automates the lift-and-shift migration of servers from on-premises to AWS, supporting Windows Server and custom configurations such as SAP kernels. Option A (CloudEndure Migration) is wrong because CloudEndure has been superseded by AWS MGN and is no longer recommended for new migrations. Option B (AWS DMS) is wrong because it specializes in database migrations, not entire server instances.

Option D (AWS SMS) is wrong because it is an older, less flexible service that may not handle custom kernels as effectively as MGN.

A company is migrating a legacy on-premises Oracle database to Amazon RDS for Oracle. They need to minimize downtime. Which AWS service should they use for ongoing replication during the migration?

A.AWS Schema Conversion Tool (SCT)
B.AWS Server Migration Service (SMS)
C.AWS Database Migration Service (DMS)
D.AWS DataSync
AnswerC

AWS Database Migration Service with ongoing replication (CDC) allows near-zero downtime migration.

Why this answer

AWS Database Migration Service (DMS) with ongoing replication (change data capture) allows near-zero downtime migration. Option A (AWS Schema Conversion Tool) is wrong because it is a schema conversion tool, not a replication service. Option B (AWS Server Migration Service) is wrong because it is for server migration, not database replication.

Option D (AWS DataSync) is wrong because it is for file/object storage, not database replication.

A company is migrating its SAP system to AWS and wants to use a high-availability setup for the database layer. Which AWS service should the company use to achieve automatic failover for SAP HANA?

A.Amazon CloudFront
B.Elastic Load Balancing (ELB)
C.Amazon Route 53 with health checks
D.AWS Global Accelerator
AnswerC

Route 53 can route traffic to the standby HANA instance if the primary fails.

Why this answer

Amazon Route 53 can be configured with DNS failover using health checks to automatically redirect traffic to a standby SAP HANA database in the event of a primary failure. Option A is wrong because Amazon CloudFront is a content delivery network, not relevant for database failover. Option B is wrong because Elastic Load Balancing is designed for distributing traffic across multiple instances, not for database layer failover.

Option D is wrong because AWS Global Accelerator improves application performance by routing traffic over the AWS global network, but it does not provide automatic failover for SAP HANA.

During a migration of an SAP system, the team notices that the source system uses a custom kernel parameter that is not supported on the target Amazon EC2 instance. What should the migration team do?

A.Disable the kernel parameter in the source before migration.
B.Change the EC2 instance type to one that supports the parameter.
C.Consult the SAP on AWS documentation for equivalent parameter settings.
D.Keep the same kernel parameter and proceed with the migration.
AnswerC

AWS documentation provides guidance for SAP kernel parameters.

Why this answer

When a custom kernel parameter is not supported on the target EC2 instance, the recommended approach is to consult the SAP on AWS documentation for equivalent or alternative parameter settings that achieve the same effect within AWS's supported configurations. Option A is incorrect because disabling the parameter in the source before migration could affect the SAP system's performance or functionality during migration. Option B is incorrect because changing the EC2 instance type may not necessarily support the parameter, and it might introduce other compatibility issues.

Option D is incorrect because proceeding with an unsupported kernel parameter could lead to system instability or failure on AWS.

An organization is migrating a large on-premises data lake (500 TB) to Amazon S3. The migration must complete within 2 weeks. The network bandwidth is 1 Gbps. Which AWS service should be used?

A.AWS Direct Connect with a 10 Gbps connection
B.AWS Database Migration Service (DMS)
C.Amazon S3 Transfer Acceleration
D.AWS Snowball Edge
AnswerD

Snowball Edge provides physical devices that can transfer large volumes quickly.

Why this answer

(AWS Direct Connect with 10 Gbps) would require 10 Gbps bandwidth, but the organization only has 1 Gbps available, and provisioning a 10 Gbps connection takes weeks, so it cannot meet the 2-week timeline. Option B (DMS) is designed for database migrations, not large data lakes. Option C (S3 Transfer Acceleration) improves transfer speed over the internet but with only 1 Gbps bandwidth, it would still take over 50 days to transfer 500 TB, exceeding the 2-week deadline.

Option D (AWS Snowball Edge) is a physical device that can transfer 500 TB in about 10 days (including shipping), making it the correct choice given the bandwidth constraint and time requirement.

A company is migrating a SAP HANA database to AWS. The database is 10 TB and requires a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 2 hours. Which backup strategy should be used?

A.Use AWS DMS to replicate the HANA database to a standby instance.
B.Configure SAP HANA Backint agent to back up directly to Amazon S3 every 15 minutes.
C.Schedule SAP HANA backups to an EBS volume and copy to S3.
D.Use AWS Backup with EBS snapshots every hour.
AnswerB

Backint to S3 supports frequent backups and fast restore.

Why this answer

The SAP HANA Backint agent can back up directly to Amazon S3, allowing frequent backups (every 15 minutes) to achieve an RPO of 15 minutes. HANA Backint backups are fast and reliable, and restoring from S3 can meet the 2-hour RTO. Option A (AWS DMS replication) is for ongoing data replication, not backup; it may not support HANA backup requirements and could exceed RTO.

Option C (backups to EBS volume then copy to S3) introduces delays and manual processes, making it difficult to achieve a 15-minute RPO. Option D (AWS Backup with EBS snapshots) typically has a minimum interval of 1 hour, insufficient for a 15-minute RPO, and restoring a 10 TB database from snapshots may exceed the 2-hour RTO.

A company is migrating their SAP HANA database to AWS. The on-premises HANA system is 10 TB and runs on a physical server. They need to minimize the migration time and cannot afford more than 4 hours of downtime. The network bandwidth is limited to 500 Mbps. They decide to use AWS Snowball Edge to transfer the data. After copying the data to Snowball, they ship it to AWS. However, upon receiving the data, they find that the checksum verification fails. What should they do to resolve this issue and complete the migration within the downtime window?

A.Re-copy the data to a new Snowball and reship
B.Use AWS DMS over the existing network to transfer the data incrementally
C.Contact AWS Support to perform a remote data verification and import
D.Order an AWS Direct Connect connection to increase bandwidth
AnswerC

AWS Support can help recover data without reshipping.

Why this answer

If the checksum verification fails, AWS Support can perform a remote data verification and potentially import the data without needing to reship the Snowball, which would exceed the 4-hour downtime window. Option A is incorrect because re-copying and reshipping would take days, not fitting the downtime requirement. Option B is incorrect because even incremental transfer via DMS over a 500 Mbps link would take too long for 10 TB.

Option D is incorrect because ordering Direct Connect can take weeks to provision, which also exceeds the allowed downtime.

A company is migrating a legacy .NET application to AWS. The application uses Windows Authentication and relies on Active Directory for user authentication. The company wants to minimize changes to the application code. Which AWS service should be used to integrate Active Directory with the migrated application?

A.AWS Directory Service for Microsoft Active Directory
B.Amazon Cognito
C.AD Connector
D.Simple AD
AnswerA

Provides full managed AD with native support for Windows Authentication.

Why this answer

AWS Directory Service for Microsoft Active Directory is the correct choice because it provides a fully managed Microsoft Active Directory in the AWS cloud, which natively supports Windows Authentication and Kerberos-based authentication without requiring any code changes. This service allows the migrated .NET application to seamlessly integrate with the existing on-premises Active Directory through a trust relationship or by extending the directory directly into AWS, preserving the application's authentication logic.

Exam trap

The trap here is that candidates often confuse AD Connector with a full Active Directory service, not realizing that AD Connector only proxies LDAP queries and does not support Windows Authentication or Kerberos, which are essential for legacy .NET applications using integrated security.

How to eliminate wrong answers

Option B (Amazon Cognito) is wrong because it is designed for consumer identity and access management (CIAM) using standards like OAuth 2.0, SAML, and OpenID Connect, and does not support Windows Authentication or Kerberos protocols natively, requiring significant code changes to the .NET application. Option C (AD Connector) is wrong because it acts as a proxy to redirect directory requests to an on-premises Active Directory without storing any directory data locally, but it does not support features like Group Policy or Kerberos authentication for the application, and it requires the application to be configured to use LDAP over SSL, which may necessitate code modifications. Option D (Simple AD) is wrong because it is a standalone, Samba-based Active Directory compatible service that does not support Windows Authentication or Kerberos in the same way as native Microsoft AD, and it lacks features like trust relationships with on-premises AD, making it unsuitable for seamless integration without code changes.
