Accepted Answer

Amazon EFS: Provides shared file storage for SAP applications. Correct matches: Amazon EFS for shared file storage, Amazon FSx for Windows File Server for SMB storage, Amazon Route 53 for DNS, Amazon CloudWatch for monitoring. Common confusions include mistaking EFS for block storage and FSx for Lustre for SAP HANA.

Answer

Amazon EFS: Provides block storage for SAP HANA

Answer

Amazon FSx for Lustre: Provides high-performance shared storage for SAP HANA

Question 6

A company is running an SAP HANA database on an Amazon EC2 instance. The instance type is r5.4xlarge with 16 vCPUs and 128 GiB of memory. The storage is configured with a single 400 GB gp2 EBS volume for /hana/data and a separate 100 GB gp2 volume for /hana/log. The database experiences high latency during peak loads. Which change will most likely improve performance?

Accepted Answer

Change the EBS volumes to io2 Block Express volumes with provisioned IOPS.. SAP HANA on EC2 requires consistently low latency for /hana/data and /hana/log volumes, especially under peak loads. The gp2 volume's burst model can deplete credits, causing throughput throttling and high latency. io2 Block Express volumes provide consistent, provisioned IOPS performance without reliance on burst credits, directly addressing the latency issue.

Answer

Increase the instance size to r5.8xlarge.

Answer

Disable the EBS volume caching.

Answer

Create a RAID 0 stripe of multiple gp2 volumes.

Question 7

An organization uses AWS Systems Manager to run automation documents on their SAP EC2 instances. Recently, some automation runbooks have failed because the EC2 instances did not have the required SSM Agent version. The operations team wants to ensure all existing and future instances automatically have the latest SSM Agent. Which solution meets this requirement?

Accepted Answer

Create an AWS Systems Manager State Manager association that runs the AWS-UpdateSSMAgent document on the instances.. AWS Systems Manager State Manager can enforce a desired state configuration on EC2 instances. By creating an association that runs the `AWS-UpdateSSMAgent` document on a schedule, State Manager ensures that both existing and future instances (when configured with the appropriate instance profile and tags) automatically update to the latest SSM Agent version, regardless of the instance's lifecycle.

Answer

Use an automation document to update the SSM Agent and schedule it via a cron job on each instance.

Answer

Enable the 'Auto-update SSM Agent' option in the EC2 launch settings for all instances.

Answer

Configure AWS Systems Manager Patch Manager to update the SSM Agent.

Question 8

A company wants to migrate its on-premises SAP system to AWS. The system consists of an SAP NetWeaver application server and an SAP HANA database. The database requires ultra-low latency storage. Which AWS storage solution is most suitable for the SAP HANA data volume?

Accepted Answer

Amazon EBS io2 Block Express volumes. Amazon EBS io2 Block Express volumes are the most suitable storage solution for SAP HANA data volumes because they provide ultra-low latency, high durability, and up to 256,000 IOPS per volume with sub-millisecond latency. This meets the stringent performance requirements of SAP HANA, which demands consistent, low-latency storage for its in-memory database operations. io2 Block Express is certified by SAP for production HANA workloads on AWS.

Question 9

A company runs SAP on AWS and wants to automate the failover of their SAP HANA database across Availability Zones using a multi-AZ setup. They are using Pacemaker and STONITH fencing. Which AWS resource is commonly used as a fencing device for SAP HANA multi-AZ clusters?

Accepted Answer

Amazon CloudWatch alarm and EC2 API. STONITH (Shoot The Other Node In The Head) fencing in a multi-AZ SAP HANA cluster on AWS requires a mechanism to forcibly isolate or terminate an unresponsive node. Amazon CloudWatch alarms combined with EC2 API calls (e.g., `aws ec2 stop-instances` or `aws ec2 terminate-instances`) serve as the fencing device by triggering an API action to shut down the faulty instance, ensuring data integrity and preventing split-brain scenarios.

Question 10

An SAP Basis administrator needs to monitor the performance of their SAP HANA database running on an EC2 instance. The administrator wants to visualize key metrics such as CPU utilization, memory usage, and disk I/O in a single dashboard. Which AWS service should be used to create this dashboard?

Accepted Answer

Amazon CloudWatch Dashboards. Amazon CloudWatch Dashboards is the correct service because it allows you to create custom, single-pane-of-glass views that aggregate metrics from multiple sources, including EC2 instances. For SAP HANA on EC2, you can pull CPU utilization, memory usage, and disk I/O metrics from CloudWatch (enabled via the CloudWatch Agent or EC2 detailed monitoring) and display them together on one dashboard for real-time performance monitoring.

Question 11

A company is deploying SAP NetWeaver on AWS and needs to ensure high availability for the ASCS instance. They plan to use a shared file system for the transport directory. Which AWS storage service is most appropriate for this shared file system?

Accepted Answer

Amazon EFS. Amazon EFS provides a fully managed, scalable, and highly available NFS file system that can be mounted concurrently by multiple EC2 instances across multiple Availability Zones. For SAP NetWeaver ASCS high availability, the transport directory (/usr/sap/trans) must be shared between the active and passive ASCS instances, and EFS supports the required NFSv4 protocol with strong consistency and POSIX permissions, making it the most appropriate choice.
