Option A is wrong because the instance type is parameterized. Option B is wrong because the security group is referenced correctly. Option C is wrong because the user data script is base64 encoded correctly.

Answer

The instance type is not specified correctly.

Answer

The security group ID is not properly referenced.

Answer

The user data script is not base64 encoded correctly.

Question 3

A company runs SAP on AWS and uses a multi-AZ deployment for SAP HANA. The operations team notices that the secondary HANA node in the standby replica is not automatically taking over during a planned failover test. What is the most likely cause?

Accepted Answer

HANA system replication is not configured with 'PRIMARY' and 'SECONDARY' roles.. Option B is correct because automatic failover requires the HANA system replication to be configured with the correct mode. Option A is wrong because EBS volumes are replicated across AZs. Option C is wrong because HANA usually runs on the same instance type. Option D is wrong because Security Groups do not affect failover.

Answer

Security Groups are blocking replication traffic.

Question 8

Your SAP system on AWS uses a shared file system with Amazon EFS. The operations team notices that the SAP application is experiencing latency when reading files from EFS. Which action can improve read performance?

Accepted Answer

Enable EFS performance mode 'max I/O'.. Option D is correct because enabling EFS 'max I/O' performance mode increases the file system's ability to handle a high number of concurrent read operations by distributing data across multiple servers within the AWS region. This mode is specifically designed for workloads like SAP that require high throughput and low-latency access to shared files, as it scales I/O operations horizontally without the bottleneck of a single file server.

Answer

Use Amazon FSx for Windows File Server instead.

Answer

Move the file system to Amazon EBS with provisioned IOPS.

Answer

Use Amazon S3 with Transfer Acceleration.

Question 9

An SAP administrator needs to ensure that all EC2 instances in the SAP landscape have the correct patches and configurations. Which AWS service can be used to automate OS patch management?

Accepted Answer

AWS Systems Manager Patch Manager. Option D is correct because AWS Systems Manager Patch Manager automates patching. Option A is wrong because OpsWorks is for Chef/Puppet. Option B is wrong because CloudFormation is for infrastructure. Option C is wrong because Config is for compliance.

Question 15

A company runs SAP on AWS and uses a Multi-AZ architecture. The SAP application servers are in an Auto Scaling group across two Availability Zones, and the database is an RDS for SAP HANA Multi-AZ DB instance. During a recent failover test, the database failover completed within 2 minutes, but the application servers took 10 minutes to reconnect to the database. Which action would minimize the application reconnection time?

Accepted Answer

Use an RDS Proxy to manage database connections from the application servers.. Option D is correct because using an RDS proxy minimizes connection disruptions by pooling and reusing database connections during failovers, reducing application reconnection time. Option A is wrong because shortening the health check grace period doesn't affect reconnection. Option B is wrong because increasing the number of application servers doesn't address reconnection logic. Option C is wrong because an RDS Multi-AZ failover already happens automatically within minutes.

Answer

Reduce the health check grace period on the Auto Scaling group.

Answer

Configure the SAP application to use the RDS Multi-AZ automatic failover endpoint.

Answer

Increase the minimum number of application servers in the Auto Scaling group.
