A company is migrating a legacy Oracle database to Amazon RDS for Oracle. The source database is 11.2.0.4 and the target is 12.1.0.2. Which AWS service should be used for the migration with minimal downtime?

A.Create an RDS read replica from the source database using Oracle Data Guard.

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

DMS with CDC enables continuous replication with minimal downtime.

Why this answer

AWS DMS supports heterogeneous migrations and can replicate data with minimal downtime. Option B is correct because DMS can handle the version upgrade. Options A, C, and D are incorrect: SCT is for schema conversion, not data migration; Snowball is for offline data transfer; RDS CreateDBSnapshot is for backups, not live migration.

MCQhard

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

Option C is correct because LVM uses SSH for communication; if the SSH session times out due to inactivity, the replication fails. Option A is incorrect because LVM does not require SCT. Option B is incorrect because HANA MDC is supported by LVM.

Option D is incorrect because the migration does not require an SAP router.

Select 2 answers

A.AWS OpsWorks

B.AWS Service Catalog

C.AWS CloudFormation

D.AWS Elastic Beanstalk

E.AWS CodePipeline

AnswersC, D

CloudFormation enables infrastructure as code for SAP.

Why this answer

Option A is correct because AWS CloudFormation can provision infrastructure as code. Option C is correct because AWS Elastic Beanstalk can deploy applications, but for SAP, CloudFormation is more common. Option B is wrong because AWS CodePipeline is for CI/CD, not infrastructure deployment.

Option D is wrong because AWS OpsWorks is for Chef/Puppet, but not typical for SAP. Option E is wrong because AWS Service Catalog is for governance, not automation. So correct: A and C.

MCQmedium

A healthcare company is migrating its SAP Business Suite system to AWS. The system includes an SAP HANA database (1.5 TB) and an SAP NetWeaver application server. They plan to use SAP HANA System Replication (HSR) for the database and AWS Application Migration Service (MGN) for the application server. The network connection is AWS Direct Connect with 500 Mbps bandwidth. During a test migration, the HSR replication is working, but the MGN replication for the application server is extremely slow. The MGN console shows that the replication is progressing at only 10 Mbps. The source application server is a physical machine with a 300 GB disk, 60% utilized. The administrator has verified that there are no other applications consuming significant network bandwidth. Which action is most likely to improve the MGN replication speed?

A.Increase the bandwidth limit setting in the MGN agent configuration on the source server.

B.Change the target EC2 instance type to a larger size.

C.Request an increase in the Direct Connect bandwidth to 1 Gbps.

D.Change the staging area disk on the source server from HDD to SSD.

AnswerA

MGN agent has a configurable bandwidth throttle.

Why this answer

MGN uses a replication server in AWS. The source server may be throttled by the MGN agent's default bandwidth limit. Option A is correct because increasing the agent's bandwidth limit can improve speed.

Option B is wrong because changing the staging area disk type on the source does not affect replication speed. Option C is wrong because the network bandwidth is 500 Mbps, higher than 10 Mbps, so network is not the bottleneck. Option D is wrong because changing the target instance type does not affect data transfer.

MCQmedium

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

Option D is correct because SMS requires the ec2:ImportImage action to import VM images into EC2. The policy in the exhibit allows creating images but does not allow importing. Option A is wrong because SMS does not need to create snapshots directly.

Option B is wrong because SMS does not need to delete snapshots. Option C is wrong because describeRegions is not required for the replication process.

MCQmedium

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 SID and hostnames are part of the application configuration. AWS does not have a service that directly preserves these; however, using Amazon Route53 private hosted zones can ensure hostname resolution. The migration itself is done using SAP tools.

Option A (AWS CloudEndure Migration) now part of MGN. Option B (AWS DMS) is for databases. Option C (SAP Software Update Manager with DMO) can perform the migration while preserving SID and hostnames.

Option D (AWS MGN) can preserve hostnames if configured, but for SAP, SUM is the standard tool.

MCQmedium

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

Option D is correct because AWS DMS with ongoing replication allows near-zero downtime by continuously replicating changes from the source to the target. Option A is wrong because native Oracle tools may require extended downtime. Option B is wrong because AWS SCT is only for schema conversion, not data migration.

Option C is wrong because exporting to flat files requires significant downtime.

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.

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 provide low-latency, high-throughput network.

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

Snowball provides physical transport, meeting the time constraint.

Why this answer

At 1 Gbps, transferring 10 TB over the internet would take ~22 hours, exceeding the window. AWS Snowball can physically transfer the data quickly. Option D is correct.

Option A is wrong because DMS over internet is too slow. Option B is wrong because DMS over Direct Connect still limited by bandwidth. Option C is wrong because SCT does not transfer data.

MCQeasy

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.

MCQeasy

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

Option A is incorrect because migrating all systems at once is risky and complex. Option B is incorrect because migrating business processes first may not be feasible. Option C is correct because migrating by logical dependency groups (e.g., all systems in a landscape together) minimizes inter-system issues.

Option D is incorrect because migrating by system size may break dependencies.

MCQhard

A company is migrating an SAP system to AWS and needs to ensure high availability for SAP Central Services (ASCS) and Enqueue Replication Server (ERS). Which architecture meets SAP's high availability requirements?

A.Use a cluster solution with a shared file system and a virtual IP address in a multi-AZ setup

B.Deploy ASCS and ERS in a single Availability Zone with an automatic restart

C.Use an Application Load Balancer to distribute traffic between ASCS and ERS

D.Configure Amazon Route 53 health checks to failover between ASCS and ERS

AnswerA

This is the recommended architecture for SAP ASCS/ERS HA, using Pacemaker and a floating IP.

Why this answer

Option D is correct because using a cluster with a shared file system and a virtual IP address in a multi-AZ deployment is the standard SAP HA architecture. Option A is wrong because a single AZ does not protect against AZ failure. Option B is wrong because an Application Load Balancer is not suitable for ASCS/ERS.

Option C is wrong because Route 53 health checks alone do not provide the fast failover required.

An SAP administrator is trying to run an AWS DMS replication task from an EC2 instance that has this IAM role. The task fails with an access denied error. What is the most likely cause?

A.The EC2 instance role is not attached to the instance.

B.The S3 bucket name is incorrect.

C.The S3 actions require additional permissions for the bucket.

D.The policy does not include permissions for dms:DescribeReplicationTasks.

AnswerD

To start a task, DMS may need to describe replication tasks first.

Why this answer

Option D is correct because the DMS actions require permissions on the DMS resources (replication instances, endpoints, etc.), but the policy uses "Resource": "*" which is allowed, but the issue is that the EC2 instance is trying to call DMS actions that are not listed, such as dms:DescribeEndpoints or dms:CreateReplicationInstance. However, the most likely cause is that the policy also needs permissions for S3 actions if the task uses S3 as a source or target, but the error is access denied for DMS. Actually, the policy allows dms:CreateReplicationTask and dms:StartReplicationTask on all resources, so that should be fine.

The error might be due to missing permissions for other DMS actions like dms:DescribeReplicationTasks. But the exhibit shows only two actions. The most likely cause is that the policy does not include permissions for dms:DescribeReplicationTasks or dms:TestConnection, which are needed before starting a task.

However, option D is about missing S3 permissions if the task uses S3 as a target. Given the policy allows S3 on the bucket, that should be fine. Wait, let's re-evaluate.

The error is access denied for DMS. The policy allows CreateReplicationTask and StartReplicationTask, so those should work. Perhaps the issue is that the task needs to list endpoints or replication instances.

The most plausible answer is that the policy lacks permissions for dms:DescribeReplicationInstances. But among options, D is about S3 permissions. Actually, looking at options, option B is about missing dms:DescribeReplicationTasks, which is likely needed.

The stem says the task fails with access denied, so it might be during the start. Option B is a good candidate. However, the exhibit action list is limited.

I'll go with B.

A company is migrating a critical SAP HANA database to AWS. The database size is 2 TB. They require the highest network throughput and low latency between EC2 instances. Which EC2 placement strategy should they use?

A.Spread Placement Group across multiple Availability Zones

B.Partition Placement Group

C.Dedicated Hosts

D.Cluster Placement Group

AnswerD

Cluster group provides low latency and high throughput within a single AZ.

Why this answer

Placement Groups with Cluster Placement provide low latency and high throughput within a single AZ. Option C is correct. Option A is wrong because Spread Placement is for high availability, not performance.

Option B is wrong because Partition Placement is for large distributed systems. Option D is wrong because Dedicated Hosts provide licensing benefits, not network performance.

Select 2 answers

A.Configure the instance with 10 Gbps network bandwidth

B.Use an Amazon Machine Image (AMI) from the AWS Marketplace that includes SAP HANA

C.Ensure that the EBS volumes are optimized for high throughput

D.Confirm that the operating system is SAP certified for HANA

E.Verify that the EC2 instance type is listed in the SAP HANA certified instance list

AnswersD, E

OS certification is required.

Why this answer

SAP certification requires using certified instance types and operating systems. Option A ensures the instance is certified. Option D ensures the correct OS version.

Option B is not required because EBS optimization is standard for many instances. Option C is not a requirement. Option E is incorrect because the AMI ID is not relevant to certification.

A company is migrating its SAP HANA database to AWS. The migration requires minimal downtime and data consistency. Which THREE steps should the company take to achieve this?

Select 3 answers

A.Take a full backup of the source database and restore it on the target.

B.Use AWS DMS with change data capture (CDC) for ongoing replication.

C.Create the target HANA database and schema in advance.

D.Perform a full load of the data using AWS DMS before enabling CDC.

E.Disable all logging on the source database to reduce overhead.

AnswersB, C, D

CDC enables continuous replication of changes.

Why this answer

Options A, C, and E are correct. Using AWS DMS with CDC allows ongoing replication. Performing a full load first establishes the baseline.

Creating target infrastructure in advance is necessary. Option B is wrong because taking a backup and restoring would cause downtime. Option D is wrong because disabling CDC would prevent ongoing replication.

A company is migrating a web application from an on-premises data center to AWS. The application uses a MySQL database that is 500 GB in size. The company wants to minimize downtime during the migration. Which approach should the company use?

A.Use an RDS read replica and promote it

B.Use AWS Database Migration Service (DMS) with ongoing replication

C.Stop the database, take a mysqldump, and restore to RDS

D.Use AWS Schema Conversion Tool (SCT) to migrate the schema and data

AnswerB

DMS migrates data while changes are replicated, minimizing downtime.

Why this answer

AWS Database Migration Service (DMS) with ongoing replication (change data capture, CDC) allows you to perform a live migration with minimal downtime. You can start a full load of the 500 GB MySQL database while the source remains operational, then enable CDC to replicate ongoing changes until you cut over to the target RDS instance, reducing the downtime window to seconds.

Exam trap

The trap here is that candidates often confuse AWS DMS with AWS SCT, assuming SCT handles data migration, when in fact SCT only converts schema and code, while DMS is the service that performs the actual data migration with minimal downtime via CDC.

How to eliminate wrong answers

Option A is wrong because an RDS read replica can only be created from an existing RDS instance, not from an on-premises MySQL database, so it cannot be used for migrating from on-premises to AWS. Option C is wrong because stopping the database to take a mysqldump and restore it causes significant downtime (hours for 500 GB), which contradicts the requirement to minimize downtime. Option D is wrong because AWS Schema Conversion Tool (SCT) is designed for heterogeneous migrations (e.g., Oracle to Aurora) or schema conversion, not for minimizing downtime in a homogeneous MySQL-to-RDS migration; it does not provide ongoing replication to reduce cutover time.

Refer to the exhibit. A company is migrating its data to Amazon S3. The security team has provided this IAM policy for the migration user. However, the migration fails with an Access Denied error when trying to upload files to the bucket. What is the most likely cause?

A.The bucket policy explicitly denies the s3:PutObject action for the IAM user.

B.The IAM policy does not include s3:PutObject permission.

C.The IAM policy does not include kms:Decrypt permission.

D.The bucket has default encryption enabled and the IAM user does not have permission to use the encryption key.

AnswerA

A bucket policy with a deny statement would override the IAM allow, causing Access Denied.

Why this answer

The policy specifies the resource as 'arn:aws:s3:::example-bucket/*' for s3:PutObject. This resource ARN is correct for object-level operations. However, the error could be due to bucket policy that denies the upload, or the IAM user lacks s3:PutObjectAcl or other permissions.

But the most likely cause given the policy is that the bucket policy explicitly denies the action. Option A is wrong because the policy does allow s3:PutObject. Option B is wrong because there is no encryption requirement in the policy.

Option C is wrong because the policy does not include kms:Decrypt, but if encryption is required, the policy would need additional actions. Option D is correct because a bucket policy with a deny statement would override the allow.

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database size is 2 TB and the network bandwidth between the on-premises data center and AWS is 100 Mbps. The company needs to minimize the migration time and wants to use AWS DMS. Which approach should they take?

A.Use AWS Database Migration Service (DMS) with AWS Direct Connect to increase bandwidth.

B.Use AWS DMS with a full load over the network, then ongoing replication.

C.Use AWS DMS with AWS Snowball Edge for the full load, then ongoing replication.

D.Use AWS Schema Conversion Tool (SCT) to convert the schema and then AWS DMS for full load.

AnswerC

Snowball Edge accelerates initial load; ongoing replication uses DMS.

Why this answer

Option B is correct because AWS Snowball Edge can be used with AWS DMS to transfer the full load of large databases over a physical device, avoiding long upload times over limited bandwidth. After the full load, ongoing replication via DMS handles changes. Options A and D would take too long over 100 Mbps; Option C is for homogeneous migrations, but the full load over low bandwidth is slow.

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and has a 24-hour migration window. The company has a 1 Gbps dedicated connection to AWS. Which migration approach minimizes downtime?

A.Use AWS Schema Conversion Tool (AWS SCT) to convert the schema and AWS DMS for full load only.

B.Use native Oracle Data Pump export and import to transfer the database over the dedicated connection.

C.Use AWS Database Migration Service (AWS DMS) with ongoing replication from the on-premises database to Amazon RDS.

D.Use AWS DataSync to copy the database files to Amazon S3, then restore to Amazon RDS.

AnswerC

Ongoing replication minimizes downtime by keeping the target in sync until cutover.

Why this answer

AWS DMS with ongoing replication allows continuous data synchronization, minimizing downtime by enabling a cutover with minimal data loss. Option A is wrong because AWS SCT is for schema conversion, not data migration. Option B is wrong because a native Oracle export/import requires downtime for the export and import operations.

Option D is wrong because AWS DataSync is for file-based data, not databases.

A company is migrating its SAP systems to AWS and needs to ensure high availability for the SAP Central Services (ASCS) instance. Which AWS service can be used to implement a failover cluster for ASCS?

A.Amazon S3

B.Application Load Balancer (ALB)

C.AWS using shared file system and DNS-based failover

D.Amazon RDS Multi-AZ

AnswerC

Shared file system (e.g., EFS) with DNS-based routing provides ASCS failover.

Why this answer

AWS offers the SAP on AWS High Availability guide, but for ASCS failover, the recommended approach is using a shared file system (e.g., EFS) and AWS services like Route53 for DNS failover. Option D is the best answer. Option A (ELB) is for web traffic.

Which TWO AWS services can be used to migrate on-premises SAP systems to AWS? (Choose 2.)

Select 2 answers

A.AWS Schema Conversion Tool (SCT)

B.AWS Direct Connect

C.AWS Server Migration Service (SMS)

D.AWS Database Migration Service (DMS)

E.Amazon CloudFront

AnswersC, D

SMS is used for server-level migration.

Why this answer

AWS Server Migration Service (SMS) is correct because it automates the replication of live on-premises servers, including SAP application servers, to AWS as Amazon Machine Images (AMIs). This allows you to migrate the entire SAP server stack (OS, SAP binaries, configurations) without needing to reinstall or reconfigure the SAP software, making it ideal for lift-and-shift migrations.

Exam trap

The trap here is that candidates often confuse AWS DMS as only a database migration tool and overlook that it can also migrate SAP databases (e.g., SAP HANA, SAP ASE) to AWS, while simultaneously thinking that AWS SCT (a schema conversion tool) is needed for SAP migrations, when in fact SCT is irrelevant for SAP systems that are not changing database engines.

A company is migrating their SAP ERP system running on an on-premises IBM Db2 database to Amazon RDS for Db2. The migration must have minimal downtime. The current database size is 2 TB. The network link between on-premises and AWS is 1 Gbps. The migration team plans to use AWS DMS with a full load followed by ongoing replication. During a test migration, they notice that the full load takes longer than expected, causing the change data capture (CDC) lag to grow. They need to adjust the migration approach to meet the downtime window. What should they do?

A.Use multiple DMS tasks in parallel for the full load

B.Increase the compute capacity of the DMS replication instance

C.Create an RDS read replica to offload the initial load

D.Use AWS Snowball to transfer the initial load and then resume CDC

AnswerB

A larger replication instance can process the full load faster.

Why this answer

Option A is correct because using a larger instance for the DMS replication instance increases throughput for the full load, reducing the time and preventing CDC lag growth. Option B is wrong because the database is on-premises, not RDS. Option C is wrong because CDC is already in use; parallel tasks would complicate and may not help.

Option D is wrong because Snowball is for offline transfer, which would not allow ongoing replication.

An organization is migrating a large SAP HANA workload to AWS. The current on-premises environment uses IBM Spectrum Scale (GPFS) for shared storage. Which AWS storage solution should they use to provide a similar shared file system for SAP HANA?

A.Amazon S3

B.Amazon Elastic Block Store (EBS)

C.Amazon FSx for NetApp ONTAP

D.Amazon Elastic File System (EFS)

AnswerC

FSx for ONTAP provides a high-performance shared file system compatible with SAP HANA.

Why this answer

Amazon FSx for NetApp ONTAP provides a fully managed shared file system that supports NFS, SMB, and iSCSI protocols, and can replace GPFS for SAP HANA. EBS is block storage not shared. S3 is object storage.

C.i3en.24xlarge

D.x1e.32xlarge

AnswerD

x1e instances are SAP HANA certified and memory-optimized.

Why this answer

SAP HANA on AWS requires certified instances. The x1e.32xlarge is certified for SAP HANA production workloads. Option A is correct because it is a SAP HANA certified instance with high memory.

Option B (m5.24xlarge) is general-purpose and not certified for HANA. Option C (c5.18xlarge) is compute-optimized, not memory-optimized. Option D (i3en.24xlarge) is storage-optimized, not SAP HANA certified.

A company is migrating an SAP system to AWS and needs to retain the same hostname for the SAP application server after migration. Which configuration should the company use?

A.Assign an Elastic IP to the EC2 instance and update the /etc/hosts file

B.Create a private hosted zone in Amazon Route 53 with an A record

C.Create a CNAME record in a public hosted zone pointing to the EC2 instance

D.Use a public hosted zone in Route 53 with an A record

AnswerB

Provides internal DNS resolution within VPC.

Why this answer

Option B is correct because a private hosted zone in Amazon Route 53 allows you to create an A record that maps a custom hostname to the private IP address of an EC2 instance. This ensures that the SAP application server retains the same hostname after migration, as DNS resolution within the VPC will consistently return the instance's private IP, regardless of instance changes or restarts.

Exam trap

The trap here is that candidates often confuse Elastic IPs with hostname persistence, assuming a static public IP is sufficient, but SAP systems rely on internal hostname resolution via DNS or /etc/hosts, not public IPs, and a private hosted zone provides the necessary centralized, scalable DNS solution within the VPC.

How to eliminate wrong answers

Option A is wrong because assigning an Elastic IP to the EC2 instance only provides a static public IP, but the hostname resolution still relies on DNS or /etc/hosts; updating /etc/hosts is a manual, non-scalable solution that does not provide centralized DNS management and can break if the instance IP changes. Option C is wrong because a CNAME record in a public hosted zone points to a DNS name (e.g., the EC2 instance's public DNS), not to the instance directly, and public hosted zones are accessible from the internet, which is unnecessary and introduces security risks for an internal SAP system. Option D is wrong because a public hosted zone with an A record would expose the SAP application server's hostname to the public internet, which is not required for internal migration and violates security best practices.

A company is migrating a highly critical SAP HANA database to AWS. They need to ensure data consistency and minimal downtime. Which approach should they use?

A.Create an AMI of the on-premises HANA server and launch it on AWS

B.Use AWS DMS with ongoing replication

C.Export HANA data to S3 and import into a new HANA instance

D.Use SAP HANA system replication and AWS Launch Wizard

AnswerD

System replication provides low RPO/RTO; Launch Wizard simplifies deployment.

Why this answer

Using SAP HANA system replication with AWS Launch Wizard automates the setup and provides synchronous replication for consistency. Option A is wrong because DMS with CDC may not support HANA replication efficiently. Option B is wrong because an AMI snapshot is not a migration method.

Option D is wrong because S3 cannot be used directly for HANA replication.

MCQhard

A mid-size company is migrating its SAP Business One on SAP HANA to AWS. The current system runs on a single server with 256 GB RAM and uses a local disk for HANA data. The company wants to minimize capital expenditure and operational overhead. They have already sized the target EC2 instance as an x1e.2xlarge (122 GB RAM) but later realized that SAP HANA requires at least 256 GB RAM for their workload. The migration deadline is in one week. The company has a limited budget and cannot change the instance type to a larger one due to procurement delays. They have an 8 TB EBS gp2 volume attached for HANA data, but it is not meeting performance requirements. The team proposes the following actions: Option A: Increase the EBS volume size to 16 TB to improve IOPS. Option B: Switch to EBS io2 volumes with provisioned IOPS to meet performance requirements, and use AWS DMS to migrate the data. Option C: Use an instance with instance store SSDs (e.g., i3en.2xlarge) to get high local I/O performance, and migrate using SAP HANA backup and restore. Option D: Use Amazon FSx for NetApp ONTAP as the storage backend for HANA, as it provides high performance and is certified for SAP HANA. Which option is the best course of action considering the constraints?

A.Increase the EBS volume size to 16 TB to improve IOPS

B.Use Amazon FSx for NetApp ONTAP as the storage backend for HANA, as it provides high performance and is certified for SAP HANA

C.Use an instance with instance store SSDs (e.g., i3en.2xlarge) to get high local I/O performance, and migrate using SAP HANA backup and restore

D.Switch to EBS io2 volumes with provisioned IOPS to meet performance requirements, and use AWS DMS to migrate the data

AnswerD

io2 volumes provide consistent high IOPS, and DMS can migrate data efficiently.

Why this answer

Option C is the best because i3en instances offer high-performance instance store SSDs that are SAP HANA certified, and the instance has enough RAM (i3en.2xlarge has 64 GB RAM, but actually i3en.2xlarge has 64 GB, still less than 256 GB. However, the question states the company cannot change instance type, but they can consider a different instance family. Actually, i3en.2xlarge has 64 GB RAM, which is insufficient.

But given the constraints, the best among options is to use a certified instance with sufficient RAM? Let me correct: The company already selected x1e.2xlarge (122 GB RAM) but needs 256 GB. They cannot change instance type due to procurement delays. Option C suggests using i3en.2xlarge (64 GB RAM) which is even smaller.

Option A increases storage but not performance. Option B uses io2 but still on x1e.2xlarge with insufficient RAM. Option D: FSx for NetApp ONTAP is not SAP HANA certified.

Actually, the correct answer should be to use a larger instance, but that's not an option. The best among flawed options: Option B at least improves storage performance, but RAM issue remains. However, the question likely expects Option B because it addresses performance and uses DMS for migration.

But let's provide a realistic explanation: The company should increase storage performance and migrate with DMS. Option B is the most feasible.

The SAP system is heavily customized with many ABAP programs and custom database objects. The migration team plans to use SAP Software Update Manager (SUM) with the Database Migration Option (DMO). During the migration rehearsal, the SUM DMO process fails during the database migration phase with an error indicating that the source database character set is not supported by the target SAP HANA. The source Oracle database uses the WE8ISO8859P1 character set. The team needs to resolve this issue before the final migration. Which course of action should the team take?

A.Use SAP HANA Studio migration tools to convert the character set during migration without changing the source.

B.Use AWS Database Migration Service (AWS DMS) to migrate the data and automatically convert the character set.

C.Convert the source Oracle database character set to UTF-8 (AL32UTF8) before starting the SUM DMO migration.

D.Change the target SAP HANA database to use the WE8ISO8859P1 character set by modifying the HANA database parameters.

B.Migrate the database to a single large Amazon EC2 instance using AWS Application Migration Service.

C.Use AWS DMS to migrate the database to Amazon RDS Multi-AZ deployment.

D.Migrate to Amazon RDS with Multi-AZ deployment and use DMS for initial load.

AnswerC

DMS can perform the initial migration with minimal downtime, and RDS Multi-AZ provides synchronous standby for automatic failover, ensuring high availability.

Why this answer

Option C is correct because AWS DMS can perform a live migration with minimal downtime by continuously replicating changes from the source database to the target Amazon RDS Multi-AZ deployment. Multi-AZ provides automatic failover to a standby replica in a different Availability Zone, ensuring the highest availability for the database tier. This combination minimizes downtime during migration and provides built-in high availability post-migration.

Exam trap

The trap here is that candidates often think migrating to a single-AZ RDS with snapshots is sufficient for high availability, but they overlook that Multi-AZ is required for automatic failover and that DMS should be used for the migration itself, not as an afterthought.

How to eliminate wrong answers

Option A is wrong because a single-AZ RDS deployment does not provide high availability; if the AZ fails, the database becomes unavailable until manual recovery from snapshots, which incurs significant downtime. Option B is wrong because migrating to a single large EC2 instance creates a single point of failure; if the instance or its underlying hardware fails, the database is unavailable, and there is no automatic failover. Option D is wrong because it reverses the recommended order: you should use DMS for the initial load and ongoing replication to a Multi-AZ target, not migrate first and then use DMS; the described approach would require an additional migration step and does not leverage DMS for minimizing downtime.

A company is migrating an SAP NetWeaver system to AWS. The system uses SAProuter for secure network communication. What is the recommended approach to preserve the SAProuter functionality during the migration?

A.Deploy SAProuter on an EC2 instance with an Elastic IP address

B.Use an AWS NAT Gateway to route traffic

C.Establish an AWS Site-to-Site VPN connection

D.Use an AWS Application Load Balancer

AnswerA

EC2 with Elastic IP provides a stable endpoint and allows existing SAProuter rules to be reused.

Why this answer

Option C is correct because deploying SAProuter on an EC2 instance with an Elastic IP ensures a stable endpoint and maintains existing SAProuter rules. Option A is wrong because a NAT Gateway does not support SAProuter directly. Option B is wrong because a VPN connection does not replace SAProuter.

Option D is wrong because an Application Load Balancer is for HTTP/HTTPS traffic, not SAProuter.

A company is migrating its SAP landscape to AWS and plans to use an SAP HANA multi-node scale-out configuration. Which THREE considerations are important for the network design?

Select 3 answers

A.Use a placement group to ensure nodes are in close proximity

B.Dedicate a separate network interface for HANA inter-node traffic

C.Use a NAT Gateway for inter-node traffic

D.Use public IP addresses for inter-node communication

E.Ensure low latency (less than 1ms RTT) between all nodes

AnswersA, B, E

Placement groups reduce latency between instances.

Why this answer

For HANA scale-out, low latency between nodes (less than 1ms RTT) is required, placement groups ensure proximity, and dedicated network for HANA ensures performance. Option A (public IPs) is not required. Option D (NAT Gateway) is for internet access.

Option E (separate VPC) is not needed.

A company is migrating a large SAP S/4HANA system (8 TB total data, high I/O) from on-premises to AWS. The SAP system runs on HANA database and uses a three-tier architecture with application servers and database servers. The migration plan must minimize downtime and ensure data consistency. The company has a 10 Gbps direct connection to AWS. They have considered using AWS DMS, but the database is SAP HANA, which is not supported as a source by DMS. The migration team needs to transfer the HANA database and also the application files. They also need to replicate ongoing changes to minimize downtime. Which combination of AWS services should the migration team use? (Choose the best answer.)

A.Use AWS Application Migration Service (MGN) for the application servers. Use HANA Backint agent to back up the database to S3 and perform incremental backups for ongoing replication.

B.Use AWS DataSync to copy the entire HANA database files (data and log volumes) and application files to AWS. Then restore from the copied files.

C.Use AWS Database Migration Service (DMS) with SAP HANA as a source by installing a custom connector. Use AWS DataSync for application files.

D.Use AWS DMS for the HANA database using a homogeneous migration. Use AWS MGN for the application servers.

AnswerA

MGN can replicate the application servers with minimal downtime. HANA Backint to S3 allows full and incremental backups, enabling point-in-time recovery and minimal downtime.

Why this answer

AWS DataSync can transfer large files efficiently over Direct Connect. HANA database backup to S3 using Backint allows incremental backups and can be used with S3 for ongoing replication. AWS HANA replication is not a service; SAP HANA system replication is a feature.

AWS MGN can replicate the entire server including OS and application. The best combination is to use MGN for the application servers and Backint to S3 for HANA database backup and recovery. Option C is correct.

Option A is not suitable because DMS cannot migrate HANA. Option B is not efficient for ongoing replication. Option D includes AWS DMS which is not supported.

A company is migrating an on-premises application to AWS. The application requires low-latency access to a shared file system that can be mounted by multiple EC2 instances simultaneously. Which storage solution should they use?

A.Amazon Elastic File System (EFS)

B.Amazon Elastic Block Store (EBS)

C.Amazon Simple Storage Service (S3)

D.Amazon EC2 Instance Store

AnswerA

EFS is a managed NFS file system for multiple instances.

Why this answer

Amazon EFS provides a scalable, shared file system for multiple EC2 instances. Option A is correct. Option B is wrong because EBS volumes can be attached to only one instance.

Option C is wrong because S3 is object storage, not a file system. Option D is wrong because Instance Store is ephemeral.

A company is migrating an SAP landscape to AWS. They have a requirement to retain the same hostnames and IP addresses for the SAP application servers after migration. How can they achieve this?

A.Use a NAT Gateway and assign public IPs

B.Use VPC endpoints to assign private IPs

C.Use Elastic IP addresses and a private hosted zone in Amazon Route 53

D.Use AWS Global Accelerator to assign static IP addresses

AnswerC

EIPs provide static public IPs; private hosted zone maintains custom hostnames.

Why this answer

Using AWS Elastic IP addresses (EIP) and Private Hosted Zones with Route 53 allows static IPs and custom DNS. Option A is wrong because NAT Gateway is for outbound traffic. Option C is wrong because AWS Global Accelerator uses anycast IPs, not fixed hostnames.

Option D is wrong because VPC endpoints are for private connectivity to AWS services.

A company is migrating an SAP system to AWS and needs to ensure that the migration complies with regulatory requirements for data residency. The source system is in Germany and the target AWS Region is Frankfurt. Which step should be taken to address data residency?

A.Use AWS Artifact to review and accept the Data Processing Agreement (DPA) for the Frankfurt region.

B.Enable cross-region replication to the eu-west-1 (Ireland) region for disaster recovery.

C.Use AWS Database Migration Service (AWS DMS) with ongoing replication to a secondary cluster in Frankfurt.

D.Configure AWS Config rules to prevent data from leaving the Frankfurt region.

AnswerA

AWS Artifact provides compliance documents and DPAs that address data residency requirements.

Why this answer

Using AWS Artifact to review and accept Data Processing Agreements (DPAs) specific to the Frankfurt region ensures compliance with EU data residency requirements. Option A is wrong because data must reside in Frankfurt, not be transferred to eu-central-1? Actually Frankfurt is eu-central-1, but enabling cross-region replication would violate data residency. Option B is wrong because AWS DMS replicates data continuously, which may not satisfy data residency if replication crosses regions.

Option D is wrong because AWS Config rules do not enforce data residency.
