AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 63

A company is migrating its SAP workloads to AWS. The company’s IT team installs a highly available SAP S/4HANA system that uses the SAP HANA system replication cluster package on SUSE Linux Enterprise Server. The IT team deploys the system by using cluster nodes in different Availability Zones within the same AWS Region.
After the initial launch of the SAP application, the application is accessible. However, after failover, the IT team cannot access the application even though the system is up and running on the secondary node. After investigation, an SAP solutions architect discovers that the virtual IP address has not been used correctly.
Which combination of steps should the SAP solutions architect take to resolve this problem? (Choose two.)

Answer options

• A. Use an overlay IP address as a secondary IP address with the primary node of the cluster.
• B. Choose an overlay IP address within the VPC CIDR block that corresponds with the secondary node of the cluster.
• C. Use an overlay IP address as a virtual IP address.
• D. Choose an overlay IP address within the VPC CIDR block that corresponds with the primary node of the cluster.
• E. Choose an overlay IP address outside the VPC CIDR block that hosts the application and the database.

Correct answer: C, E

Explanation

The correct steps are to implement an overlay IP address as a virtual IP address (C) and select an overlay IP address outside the VPC CIDR block (E) to ensure proper routing and accessibility after failover. Options A, B, and D do not resolve the issue of the virtual IP address not being accessible post-failover.
