Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

An IAM role with permissions for EC2, EBS, and CloudFormation actions. The AWS LaMa connector automates SAP system copy and relocation by orchestrating EC2, EBS, and CloudFormation actions. An IAM role with permissions for these services is required so that LaMa can programmatically manage infrastructure resources (e.g., stop/start instances, snapshot volumes, create CloudFormation stacks) without manual intervention. This role is assumed by the LaMa connector when executing workflows.

Answer

An EC2 Auto Scaling group configured for the SAP application tier

Answer

AWS Systems Manager managed instances for all SAP servers

Answer

SSH keys for all SAP instances to allow LaMa to connect

Question 2

An SAP system is running on AWS with an SAP HANA database. The administrator needs to back up the HANA database to Amazon S3. Which AWS service or feature should be used to perform efficient incremental backups?

Accepted Answer

AWS Backup with the SAP HANA backup plan. AWS Backup with the SAP HANA backup plan is correct because it provides native integration for SAP HANA databases, enabling automated, incremental, and log backups directly to Amazon S3. It uses the SAP HANA Backint agent to stream backup data to S3, supporting efficient incremental backups by only transferring changed data blocks since the last full or incremental backup, which minimizes storage and network costs.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS Storage Gateway with volume gateway

Answer

Amazon EBS snapshots of the HANA data volumes

Question 3

A company is designing an SAP S/4HANA deployment on AWS with high availability. They want to use a shared file system for the SAP transport directory. Which AWS service should they use for this shared file system?

Accepted Answer

Amazon EFS. Amazon EFS is the correct choice because it provides a fully managed, POSIX-compliant, NFS-based shared file system that can be mounted concurrently by multiple EC2 instances across different Availability Zones, which is exactly what an SAP transport directory requires. The SAP transport directory (e.g., /usr/sap/trans) must be accessible from all SAP application servers in the high-availability cluster, and EFS supports the necessary file locking and consistency semantics for SAP's transport management system (TMS).

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with multi-attach enabled

Answer

Amazon S3

Question 4

An SAP administrator is planning a Disaster Recovery (DR) strategy for SAP HANA on AWS. The DR site is in a different AWS Region. Which AWS service can replicate SAP HANA data to the DR region with low Recovery Point Objective (RPO)?

Accepted Answer

SAP HANA System Replication with log shipping. SAP HANA System Replication with log shipping is the correct choice because it provides near-synchronous or synchronous replication of HANA data and transaction logs to a secondary system in another AWS Region, enabling a Recovery Point Objective (RPO) of seconds or even zero data loss. This native HANA feature is optimized for SAP workloads and integrates directly with HANA's persistence layer, making it the most suitable DR method for low RPO requirements.

Answer

Amazon EBS snapshots copied to the DR region

Answer

AWS Database Migration Service (DMS) with ongoing replication

Answer

Amazon S3 cross-region replication

Question 5

A company runs SAP NetWeaver on AWS and needs to ensure that the SAP application server instances are evenly distributed across two Availability Zones. Which AWS service should be used to distribute traffic?

Accepted Answer

Application Load Balancer. The Application Load Balancer (ALB) distributes incoming traffic across multiple targets, such as SAP application servers, in different Availability Zones. By registering SAP instances in two AZs and enabling cross-zone load balancing, the ALB ensures even distribution of traffic across both zones, which is critical for high availability and balanced resource utilization in SAP NetWeaver deployments.

Answer

AWS Global Accelerator

Answer

Amazon CloudFront

Answer

Amazon Route 53 weighted routing

Question 6

A company is deploying SAP S/4HANA on AWS and needs to ensure high availability for the database layer. Which TWO actions should the company take?

Accepted Answer

Configure SAP HANA System Replication across two Availability Zones. SAP HANA System Replication (HSR) across two Availability Zones provides synchronous or asynchronous data replication at the database level, ensuring automatic failover and high availability for the HANA database. This is a core requirement for SAP S/4HANA on AWS, as it protects against AZ-level failures and meets SAP's HA architecture guidelines.

Answer

Store HANA backups in Amazon S3 Standard-IA

Answer

Use Amazon EFS as the data volume for HANA

Answer

Enable EC2 Auto Scaling for the HANA instance

Question 7

An SAP administrator is designing a backup strategy for SAP HANA on AWS. Which THREE practices should be implemented to ensure reliable backups?

Accepted Answer

Take consistent EBS snapshots of HANA volumes after quiescing the database. Consistent EBS snapshots of HANA volumes after quiescing the database ensure crash-consistent backups, which are essential for SAP HANA's data integrity. Quiescing flushes all in-memory data to disk and freezes I/O, allowing the snapshot to capture a point-in-time state that HANA can recover from without corruption. Without quiescing, snapshots may be inconsistent and lead to database failures during restore.

Answer

Store backups in Amazon S3 One Zone-IA

Answer

Disable encryption on backup targets to reduce latency

Question 8

A company runs SAP Business Suite on AWS. They plan to use the SAP Landscape Management (LaMa) connector to automate system copy and relocation. What is a prerequisite for using the AWS LaMa connector?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Pre-allocated Elastic IP addresses. Pre-allocated Elastic IP addresses (Option C) are correct because in a pilot light DR setup, you need to ensure that the Elastic IPs are reserved in the DR region ahead of time. This allows you to quickly remap them to the recovered EC2 instances during failover, avoiding the delay of requesting new IPs or dealing with IP address conflicts. By pre-provisioning the Elastic IPs, you reduce the time required to restore network connectivity and DNS mappings, which is critical for meeting RTO objectives.

Answer

An Amazon RDS for SAP HANA instance

Answer

Running EC2 instances for all SAP components

Question 9

An SAP administrator is creating an IAM policy for the AWS SAP Landscape Management (LaMa) connector. The policy includes the actions shown. Which additional action is missing for LaMa to perform its typical automation tasks?

Accepted Answer

cloudformation:CreateStack and cloudformation:DeleteStack. AWS LaMa uses AWS CloudFormation to orchestrate the provisioning and teardown of infrastructure resources during SAP system cloning, refresh, or migration operations. Without cloudformation:CreateStack and cloudformation:DeleteStack, LaMa cannot create the temporary stacks needed for tasks like host replacement or storage snapshot-based cloning.

Answer

lambda:InvokeFunction

Answer

rds:CreateDBInstance and rds:DeleteDBInstance

Answer

s3:PutObject and s3:GetObject

Question 10

An SAP administrator configures Route 53 failover routing as shown. The health check associated with the primary record is failing. What will happen to client requests for sap.example.com?

Accepted Answer

Route 53 will return the secondary CNAME record. When the health check associated with the primary record fails, Route 53 automatically fails over to the secondary record. In this configuration, the primary record is an ALIAS record pointing to a load balancer, and the secondary record is a CNAME record. Since the primary is unhealthy, Route 53 returns the secondary CNAME record, directing clients to the failover endpoint.

Answer

Route 53 will return the ALIAS record for the primary load balancer

Answer

Route 53 will return an error

Answer

Route 53 will return both records

Question 11

A company is migrating its SAP ERP system to AWS. The system requires high availability for the SAP central services (ASCS) and must support automatic failover. Which AWS architecture should the company use to meet these requirements?

Accepted Answer

Deploy ASCS on an EC2 instance in an Auto Scaling group with a lifecycle hook that triggers a Lambda function to reattach the ASCS cluster resources.. It describes a pattern for achieving automatic failover of SAP ASCS using an Auto Scaling group with a lifecycle hook. When the ASCS instance fails, the Auto Scaling group launches a new instance, and the lifecycle hook triggers a Lambda function that reattaches the cluster resources (e.g., EIP, EBS volumes, or shared file systems) to the new instance, enabling the SAP ENSA2 or ENSA1 cluster to resume operations without manual intervention.

Answer

Configure a Network Load Balancer in front of two ASCS instances in different Availability Zones.

Answer

Use Amazon RDS Multi-AZ to host the SAP central services.

Answer

Run ASCS on a single EC2 instance in a single Availability Zone with an Elastic IP address.

Question 12

An SAP administrator notices that the SAP application server performance degrades during peak hours. The application servers are running on EC2 instances with gp2 EBS volumes. The administrator suspects the EBS volumes are experiencing burst bucket depletion. Which action should the administrator take to improve performance?

Accepted Answer

Change the volume type to gp3 and adjust the IOPS and throughput settings.. The gp2 volume type uses a credit-based burst model where performance degrades once the burst bucket is depleted, especially under sustained high I/O. Changing to gp3 provides a baseline performance that does not rely on burst credits, and you can independently provision higher IOPS and throughput without increasing storage size, directly addressing the performance degradation during peak hours.

Answer

Increase the size of the gp2 volumes to increase the baseline IOPS.

Answer

Move the data to instance store volumes for better performance.

Answer

Change the volume type to io1 and provision high IOPS.

Question 13

A company is planning to run SAP HANA on AWS and needs to ensure that the database meets the required memory and CPU performance. Which instance family should the company choose for the SAP HANA database?

Accepted Answer

X1e instances. SAP HANA is an in-memory database that requires large amounts of RAM and high memory bandwidth to keep all data in memory for real-time processing. The X1e instance family is specifically designed for high-memory workloads like SAP HANA, offering up to 4 TB of memory and high-frequency Intel Xeon processors, making it the only instance family among the options that meets SAP's certified memory and CPU requirements.

Answer

T3 instances

Answer

M5 instances

Answer

C5 instances

Question 14

An SAP system is running on AWS and uses Amazon EFS for the /sapmnt directory. The system is experiencing high latency during file operations. Which configuration change could improve the performance of the EFS file system?

Accepted Answer

Enable the Max I/O performance mode on the EFS file system.. The Max I/O performance mode is designed for highly parallel, throughput-intensive workloads like SAP /sapmnt, which involves many concurrent file operations. It scales to higher levels of aggregate throughput and IOPS by distributing data across multiple servers, reducing latency under heavy load. General Purpose mode, while suitable for latency-sensitive workloads, cannot match the parallel throughput capabilities required by SAP systems.

Answer

Change the performance mode from Max I/O to General Purpose.

Answer

Migrate the /sapmnt directory to an Amazon EBS volume.

Answer

Increase the provisioned throughput of the EFS file system.

Question 15

An SAP system uses a shared file system via Amazon FSx for Windows File Server. The system administrators report that file locks are not being released properly, causing application errors. What is the most likely cause and solution?

Accepted Answer

Enable the file lock duration feature on the FSx file system to automatically release stale locks.. Amazon FSx for Windows File Server supports a file lock duration feature that can be configured to automatically release stale file locks after a specified timeout. This directly addresses the issue of locks not being released properly, which is a common cause of application errors in SAP systems relying on shared file systems.

Answer

Increase the throughput capacity of the FSx file system.

Answer

The file system is using NFSv3 protocol; switch to NFSv4.

Answer

The file system is using Amazon S3 as the backing store; migrate to EFS.
