AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 92

An SAP engineer is designing a storage configuration for an SAP S/4HANA production system on AWS. The system will run on an Amazon EC2 instance with a memory size of 2 TB. The SAP HANA sizing report recommends storage of 2,400 GB for data and 512 GB for logs. The system requires 9,000 IOPS for data storage and throughput of 300 MBps for log storage.

Which Amazon Elastic Block Store (Amazon EBS) volume configuration will meet these requirements MOST cost-effectively?

Answer options

• A. For /hana/data, use two 900 GB Provisioned IOPS SSD (io1) EBS volumes that are configured with RAID 0 striping and the required IOPS. For /hana/log, use one 512 GB General Purpose SSD (gp3) EBS volume that is configured with the required throughput.
• B. For /hana/data, use one 2,400 GB General Purpose SSD (gp3) EBS volume that is configured with the required IOPS. For /hana/log, use one 512 GB gp3 EBS volume that is configured with the required throughput.
• C. For /hana/data use two 1,200 GB Provisioned IOPS SSD (io2) EBS volumes that are configured with RAID 0 striping and the required IOPS. For /hana/log, use one 525 GB io2 EBS volume that is configured with the required throughput.
• D. For /hana/data, use two 1,200 GB General Purpose SSD (gp3) EBS volumes that are configured with RAID 0 striping and the required IOPS. For /hana/log, use one 512 GB gp3 EBS volume that is configured with the required throughput.

Correct answer: B

Explanation

Option B is the most cost-effective solution because it uses a single 2,400 GB General Purpose SSD (gp3) volume for data, which meets the storage requirement without unnecessary complexity or cost. Other options either use more expensive volume types or unnecessary RAID configurations, increasing costs without providing additional benefit for the specified IOPS and throughput.
