AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 127

A company is deploying SAP Business Suite on SAP HANA by using two Amazon EC2 bare metal instances. The company has set up a Pacemaker cluster for SAP HANA. The cluster is set up between the two instances, which are configured to use SAP HANA system replication.

An SAP engineer notices that the overlay IP address is not reachable from the application servers. The overlay IP address is only reachable locally on the database cluster. Which actions should the SAP engineer take to resolve this issue? (Choose three.)

Answer options

• A. Turn off the source/destination check on each bare metal instance.
• B. Modify the security groups to ensure that the minimal ports for connectivity between the application server and the database are opened.
• C. Add a route table entry to the route tables for the subnets of both bare metal instances for the overlay IP address.
• D. Ensure that both bare metal instances are in the same subnet.
• E. Perform a failover and tailback by using the Pacemaker cluster. Check whether the overlay IP address routing is functioning correctly.
• F. Move the Pacemaker cluster to EC2 VM instances instead of bare metal instances.

Correct answer: A, B, C

Explanation

The correct actions involve disabling the source/destination check to allow proper routing, modifying security groups to permit necessary communication ports, and adding a route table entry for the overlay IP. The other options either do not address the connectivity issue directly or involve unnecessary changes that would not resolve the specific routing problem.
