Question #: 84
Topic #: 1

[All AWS Certified SAP on AWS - Specialty PAS-C01 Questions]

A company is running its on-premises SAP ERP Central Component (SAP ECC) system on an Oracle database on Oracle Enterprise Linux. The database is 1 TB in size and uses 27,000 IOPS for its peak performance Multiple SSD volumes are striped to store Oracle data files in separate sapdata directories to gain the required IOPS.

The company is planning to move this workload to AWS. The company chooses high I/O bandwidth instances with a Nitro hypervisor to host the target database instance. Downtime is not a constraint for the migration. The company needs an Amazon Elastic Block Store (Amazon EBS) storage layout that optimizes cost for the migration.

How should the company reorganize the Oracle data files to meet these requirements?

A. Reorganize the Oracle data files into one 9 TB General Purpose SSD (gp2) EBS volume.
B. Reorganize the Oracle data files into a striped volume of three 3 TB General Purpose SSD (gp2) EBS volumes.
C. Reorganize the Oracle data files into one 1 TB General Purpose SSD (gp3) EBS volume with 27,000 provisioned IOPS.
D. Reorganize the Oracle data files into ten 100 GB General Purpose SSD (gp3) EBS volumes.

Selected Answer: B

C is not correct as the max IOPS of gp3 is 16000. I prefer B since aach 3TB gp2 volume can provide a maximum of 9,000 IOPS (3 IOPS * 3,000 GB). Three of them combined can provide 27,000 IOPS. So, this meets the requirement.

GP3 costs 20% lower than GP2. GP3 provides first 3000 iops free. 10 GP3 with 3000 iops each will be sufficient for 27000 IOPS requirement.

D: As this is cost optimized, a single volume of GP3 has an average IOPS of 3000. When 10 are in an array you reach 30000, enough to meet the 27000 IOPS requirement. Answer C would require additional costs and max OPS for a signle GP3 volume is 16000. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/raid-config.html

Option D does not state that the volumes are in an array/striped. All of these answers are poor choices.

Selected Answer: D

You guys here talk about IOPS but A and B provide way too much storage if the database is just 1 TB so its too expensive. D should be right.

Selected Answer: C

C: The general purpose SSD (gp3) volumes allow you to provision performance independent of storage capacity and provides the flexibility to adjust IOPS and throughput as needed. For this workload, having a single 1TB gp3 volume with 27,000 provisioned IOPS would meet the company's requirements most cost-effectively.
