AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 39

A company uses an SAP application that runs batch jobs that are performance sensitive. The batch jobs can be restarted safely. The SAP application has six application servers. The SAP application functions reliably as long as the SAP application availability remains greater than 60%. The company wants to migrate the SAP application to AWS. The company is using a cluster with two Availability Zones.
How should the company distribute the SAP application servers to maintain system reliability?

Answer options

• A. Distribute the SAP application servers equally across three partition placement groups.
• B. Distribute the SAP application servers equally across three Availability Zones.
• C. Distribute the SAP application servers equally across two Availability Zones.
• D. Create an Amazon EC2 Auto Scaling group across two Availability Zones. Set a minimum capacity value of 4.

Correct answer: D

Explanation

The correct answer is D because using an Amazon EC2 Auto Scaling group allows for better management of server capacity and ensures that at least 4 servers are always running, which is crucial for maintaining reliability. Options A and B are incorrect as they do not utilize the two Availability Zones effectively and do not guarantee the necessary capacity. Option C fails to meet the minimum requirement of 60% availability by only using two Availability Zones for all servers.
