A company is migrating an SAP system to AWS and wants to use AWS Launch Wizard for deployment. They have an existing VPC and subnets. Launch Wizard requires the selection of a subnet for each component. What is the best practice for selecting subnets for high availability?

A.Use only private subnets without public access.
B.Select a single subnet in one Availability Zone for simplicity.
C.Create a new VPC and subnets specifically for Launch Wizard.
D.Select subnets in different Availability Zones to ensure high availability.
AnswerD

This meets best practices for SAP high availability on AWS.

Why this answer

For high availability, it is best to deploy SAP components across multiple Availability Zones by selecting subnets in different AZs. Launch Wizard supports this. Deploying all in one AZ creates a single point of failure.

Launch Wizard can use existing subnets.

A company is migrating an SAP HANA database from on-premises to AWS. The current system uses 8 TB of data. The migration must be completed within a 4-hour downtime window. The network link has 1 Gbps throughput. What is the MOST efficient migration strategy?

A.Use AWS Database Migration Service (DMS) with ongoing replication
B.Use AWS Direct Connect to increase bandwidth
C.Use AWS Application Migration Service (MGN)
D.Use AWS Snowball Edge to transfer the data offline
AnswerD

Snowball Edge can transfer 8 TB offline within the required time.

Why this answer

At 1 Gbps, transferring 8 TB over the network would take approximately 18 hours (8 TB * 1024 GB/TB * 8 bits/byte / 1 Gbps = 65536 seconds = ~18 hours), exceeding the 4-hour window. AWS Snowball Edge can transport 8 TB offline. Option B (AWS Snowball Edge) is correct.

Option A (AWS DMS) would not meet the time constraint. Option C (AWS MGN) is for server migration, not database. Option D (Direct Connect) still has the same bandwidth limitation.

The exhibit shows the output of the describe-replication-tasks command for an ongoing migration from SAP HANA to Amazon RDS for MySQL. The task status is 'running' but no data has been transferred after 2 hours. What is the most likely cause?

A.The replication instance has insufficient memory
B.The source endpoint is not accessible from the replication instance
C.The target endpoint is pointing to the wrong database
D.The HANA database is not configured as a target
AnswerB

If the source is not accessible, the task may get stuck in a running state without transferring data.

Why this answer

Option D is correct because a running task with no data transfer often indicates that the task has not started processing due to pending validation or network issues. However, given the status is 'running', it may be stuck in validation. The most common cause is that the source endpoint is not accessible.

Option A is wrong because if the target endpoint were wrong, the task would fail. Option B is wrong because the status is 'running', not 'failed'. Option C is wrong because the HANA database is the source, not the target.

MCQhard

A large enterprise is migrating its SAP S/4HANA system to AWS. The system includes a production SAP HANA database (4 TB) and a development SAP HANA database (1 TB). The migration strategy is to use SAP HANA System Replication (HSR) for both databases to EC2 instances in the same AWS region. The company has a compliance requirement that the production database must be in a different AWS account than the development database. The network between on-premises and AWS uses AWS Direct Connect with 10 Gbps bandwidth. During the test migration, the HSR replication for the development database works, but the production database fails to establish replication. The error log shows: "HSR connection timed out." The security groups and network ACLs for the production target EC2 instance allow inbound traffic on port 30101 from the on-premises source IP. What is the most likely cause of the failure?

A.The production target EC2 instance is in a different AWS account, and there is no VPC peering or Transit Gateway between the accounts to allow connectivity.
B.The production source HANA instance is not configured to replicate to a different AWS account.
C.The production target EC2 instance is using the wrong port for HSR.
D.The security group on the production target EC2 instance does not allow inbound traffic on port 443.
AnswerA

Cross-account communication needs VPC peering or Transit Gateway.

Why this answer

HSR requires communication between the source and target HANA instances. If the target is in a different account, VPC peering or Transit Gateway is needed for cross-account connectivity. Option A is correct because cross-account communication requires VPC peering or Transit Gateway.

Option B is wrong because the port is correct. Option C is wrong because HSR does not use port 443. Option D is wrong because the source is on-premises, not in another AWS account.

A company is migrating an on-premises SAP HANA database to AWS. The database is 10 TB and requires high IOPS. Which EC2 instance type and storage configuration is most appropriate?

A.x1e.32xlarge with EBS io1 volumes
B.r5.24xlarge with EBS io1 volumes
C.x1e.32xlarge with instance store volumes
D.r5.24xlarge with EBS gp2 volumes
AnswerA

x1e is certified for HANA, io1 provides high IOPS.

Why this answer

Option D is correct because x1e instances are SAP HANA certified and EBS io1 provides high IOPS. Option A is incorrect because gp2 is not suitable for high IOPS. Option B is incorrect because r5 instances are not HANA optimized.

Option C is incorrect because instance store is ephemeral.

A company is migrating an SAP Business Suite system to AWS. They want to reduce storage costs by using Amazon S3 for archiving. Which TWO AWS services can be used to integrate SAP with Amazon S3 for archiving?

Select 2 answers
A.Amazon S3 Batch Operations
B.Amazon S3 Glacier
C.Amazon CloudFront
D.AWS Storage Gateway (file gateway)
E.SAP Data Archiving with S3 as the archive store
AnswersD, E

File gateway presents a file interface to S3 for SAP archiving.

Why this answer

Options A and D are correct. AWS Storage Gateway provides a file interface to S3, and SAP Data Archiving can use S3 as a target. Option B is wrong because Glacier is a storage class, not a service.

Option C is wrong because CloudFront is a CDN. Option E is wrong because S3 Batch Operations is for bulk actions, not archiving.

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

Option A is incorrect because the system uses the same hostname, so DNS updates are not needed. Option B is incorrect because AWS does not enforce different private IPs; the old IP can be reused. Option C is incorrect because the same SAP SID is allowed; no change required.

Option D is correct because the Amazon EC2 instance must have the same private IP as the on-premises hostname resolves to, or the hostname must be resolvable via DNS or /etc/hosts.

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

SAP supports Sybase ASE to SAP HANA migration as part of SAP Business Suite on HANA. Migrating to SAP HANA on AWS is a strategic move and reduces complexity. Using DMS for Sybase to RDS for Sybase is possible but Sybase ASE on RDS is not a managed service; it's an EC2-based deployment.

Option C is correct because moving to HANA is a common SAP migration path and reduces overhead. Option A is wrong because DMS cannot migrate to Sybase on RDS (RDS supports Sybase? Actually RDS does not support Sybase; only EC2). Option B is wrong because using AWS MGN for the database server retains Sybase on EC2, not reducing overhead.

Option D is wrong because DataSync is not for database replication.

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

Modify is allowed under rds:*.

Why this answer

Option D is correct because the policy allows rds:* on all resources except the specific deny on DeleteDBInstance for the prod-sap-db. Therefore, the user can modify the production database. Option A is wrong because the deny on DeleteDBInstance for prod-sap-db prevents deletion.

Option B is wrong because the policy does not restrict to read-only. Option C is wrong because the policy does allow some write actions.

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.

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

Option D is correct because DRS can use multiple parallel connections (concurrent streams) to improve throughput. Option A is wrong because RDS is a managed service, not for DR of on-premises HANA. Option B is wrong because increasing staging area size does not improve 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

SAP HANA on RDS uses a single-AZ deployment by default; enabling Multi-AZ adds a standby but does not improve performance. However, the most impactful change is increasing the instance size (compute and memory) to match the on-premises capacity. Option A is wrong because RDS Multi-AZ does not improve performance.

Option B is wrong because the bandwidth is already adequate. Option D is wrong because reducing backup retention does not affect runtime performance.

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 source database is larger than the target HANA disk storage. The team needs to increase the HANA disk size to accommodate the migration. Option B is wrong because splitting the migration into chunks is complex and not standard.

Option C is wrong because DB2 compression may not help if the issue is tablespace size. Option D is wrong because AWS DMS does not support HANA.

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

Option A is correct because 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.

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
AnswerA

DMS needs these to set up the migration infrastructure.

Why this answer

Option C is correct because DMS requires permissions to create and manage DMS resources like replication instances, endpoints, and subnet groups. The policy lacks 'dms:CreateReplicationInstance' and 'dms:CreateEndpoint' which are necessary for the task to function. Option A is wrong because S3 permissions are present.

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

Option C is correct because increasing the instance size of the DMS replication instance can improve performance and reduce CDC latency. Option A is wrong because disabling logging would break CDC. Option B is wrong because increasing the target database size may help but not directly reduce DMS latency.

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

Option D is correct. AWS MGN does not automatically replicate the /etc/hosts file; after migration, the new instance's private IP changes, so /etc/hosts must be updated. Option A is incorrect because AWS MGN supports SLES.

Option B is incorrect because AWS MGN replicates the entire OS disk including /etc/sysconfig/network. Option C is incorrect because Route 53 is not required for internal hostname resolution.

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

Option B is correct because 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.

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

Option C is correct because 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.

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.

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 is achieved using a cluster spanning two Availability Zones with a shared EFS filesystem for the /sapmnt and /usr/sap/trans directories. AWS does not support cluster-based floating IPs, so Route53 health checks are used for failover. Option A (Multi-AZ RDS) is for databases.

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.

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.

A company is migrating an SAP HANA database to AWS. They have set up HANA System Replication (HSR) between the on-premises primary and an AWS secondary. The initial data synchronization is complete, but during the final cutover, the replication breaks due to network latency. What should the company do to complete the migration successfully?

A.Perform a manual takeover to promote the AWS secondary to primary.
B.Set up a new HSR connection with a different port.
C.Increase the HSR timeout settings on the primary.
D.Restart the initial synchronization from scratch.
AnswerA

This completes the cutover and makes the AWS system the new primary.

Why this answer

The correct action is to perform a manual failover using HSR takeover, which will promote the AWS secondary to primary and allow the system to continue. Increasing timeout may not resolve underlying latency. Restarting replication will take time.

Setting up a new replication is unnecessary.

A company is migrating its SAP system to AWS and needs to transfer a large amount of data (10 TB) from the on-premises data center to AWS. Which TWO AWS services can be used for this data transfer?

Select 2 answers
A.Amazon S3 Transfer Acceleration
B.AWS DataSync
C.AWS CloudFormation
D.AWS Snowball
E.AWS Database Migration Service (DMS)
AnswersB, D

DataSync can transfer data over the network efficiently.

Why this answer

Options A and B are correct. AWS Snowball is a physical device for large-scale offline data transfer. AWS DataSync can transfer data over the network efficiently.

Option C is wrong because Amazon S3 Transfer Acceleration speeds up S3 uploads over the internet but is not a migration service. Option D is wrong because AWS DMS is for database migration. Option E is wrong because AWS CloudFormation is for infrastructure as code.

A company wants to migrate its SAP application to AWS and needs to ensure high availability for the SAP Central Services (ASCS). Which AWS feature should be used to achieve this?

A.Elastic Load Balancer (ELB)
B.Auto Scaling groups
C.Amazon Route 53 health checks with failover routing
D.Amazon CloudFront
AnswerC

Route 53 can monitor ASCS health and failover to a standby instance.

Why this answer

Amazon Route 53 with health checks and failover routing can redirect traffic to a secondary ASCS in case of failure, providing high availability. Option B (Auto Scaling) is for compute scaling, not HA. Option C (ELB) is for load balancing but not typically used for ASCS.

Option D (CloudFront) is a CDN.

Which TWO factors are most important to consider when planning the network connectivity for an SAP migration to AWS using AWS Direct Connect?

Select 2 answers
A.Number of VPC endpoints required.
B.Security group rules for the SAP application.
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 are the latency and bandwidth requirements, and the routing configuration (BGP) for failover. Option A is important for performance; Option B is important for reliability. Option C is wrong because VPC endpoints are not a Direct Connect factor.

Option D is wrong because subnets are internal to VPC. Option E is wrong because security groups are not a Direct Connect factor.

A company is planning a migration of an SAP system to AWS. Which TWO factors should be considered when selecting the AWS Region for the migration?

Select 2 answers
A.Proximity to on-premises data center and end users
B.Number of Availability Zones
C.Data residency and compliance requirements
D.AWS service cost
E.Availability of specific instance types
AnswersA, C

Lower latency improves performance.

Why this answer

Proximity to users reduces latency. Compliance requirements may mandate specific regions. Cost varies but is not primary for region selection.

Instance availability is global. Service features may vary but are secondary.

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
AnswerC

Automates recovery for SAP HANA.

Why this answer

AWS Elastic Disaster Recovery (DRS) can automate recovery for SAP HANA. Option A (AWS Backup) is for backup, not automated failover. Option B (AWS CloudFormation) is for infrastructure provisioning.

Option C (Amazon Route 53) can route traffic but does not automate database failover.

An SAP administrator is migrating an SAP system to AWS and has launched an EC2 instance from an AMI. The administrator runs the command shown in the exhibit. Which statement is true about the root volume?

A.The root volume will be deleted when the instance is terminated.
B.The root volume is detached from the instance.
C.The root volume is encrypted.
D.The root volume is an instance store volume.
AnswerA

DeleteOnTermination is true.

Why this answer

Option C is correct because the output shows DeleteOnTermination is true, meaning the root volume will be deleted when the instance is terminated. Option A is wrong because the volume is not encrypted. Option B is wrong because the volume is attached to the instance.

Option D is wrong because the volume is an EBS volume, not instance store.

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

Option D is correct because SAP ASCS requires a shared filesystem and a floating IP for high availability. AWS provides this using EFS or FSx for shared storage and a Route 53 health check with a secondary IP or an NLB with a static IP. Option A is wrong because Multi-AZ RDS is for databases, not ASCS.

Option B is wrong because ALB does not support floating IPs. Option C is wrong because EBS volumes cannot be attached to multiple instances simultaneously.
