AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 118

A company is running its SAP system on AWS with a secondary SAP HANA database in a sidecar setup. The company requires high IOPS for write performance on its Amazon Elastic Block Store (Amazon EBS) volumes for the secondary SAP HANA database.

The EBS volume that the company uses for its SAP HANA data volume cannot provide the required IOPS. Instance bandwidth for the Amazon EC2 instance that is hosting the SAP HANA database is sufficient. An SAP solutions architect needs to propose a solution to resolve the IOPS performance issue.

Which solution will achieve the required IOPS?

Answer options

• A. Replace the EBS storage with EC2 instance store storage.
• B. Create a RAID 0 configuration with several EBS volumes.
• C. Use Amazon EC2 Auto Scaling to launch Spot Instances.
• D. Create a placement group with several EBS volumes.

Correct answer: B

Explanation

The correct answer is B because creating a RAID 0 configuration with several EBS volumes can significantly increase IOPS by striping data across multiple volumes, thus enhancing write performance. Option A is incorrect as EC2 instance store storage is ephemeral and does not persist data, which is critical for a database. Option C does not address the IOPS issue directly, and while Auto Scaling can improve availability, it does not inherently enhance storage performance. Option D is also incorrect because a placement group is meant for low-latency performance between instances but does not increase IOPS for EBS volumes.
