Question 9 · No. 89 · Single choice
A company has implemented its ERP system on SAP S/4HANAon AWS. The system is based on Enqueue Standalone Architecture (ENSA2) and is highly available. As part of an availability test, the company failed over its system to secondary nodes in the second Availability Zone. When the system failed over, the initial licenses were no longer valid. What could be the reason for this behavior?
- A. . The company needs to apply SP licenses after each failover.
- B. . The cluster configuration is not correct.
- C. . The company needs two separate sets of licenses for ASS instances in each Availability Zone.
- D. . The company stopped and restarted the secondary node as part of the last maintenance.
Answer: C
Explanation: Answer is C. In a SAP HANA on AWS setup, licenses are node-bound. This means that each node (primary or secondary) requires its own individual set of licenses. When the system failed over to the secondary nodes in the second Availability Zone, the initial licenses for the primary nodes became invalid because the licenses for AWS instances and software are bound to the hardware (node). Hence, the company would need two separate sets of licenses for the secondary node.
