AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 28

A company is running SAP ERP Central Component (SAP ECC) with a Microsoft SQL Server database on AWS. A solutions architect must attach an additional 1 TB Amazon Elastic Block Store (Amazon EBS) volume. The company needs to write the SQL Server database backups to this EBS volume before moving the database backups to Amazon S3 for long-term storage.
Which EBS volume type will meet these requirements MOST cost-effectively?

Answer options

• A. Throughput Optimized HDD (st1)
• B. Provisioned IOPS SSD (io2)
• C. General Purpose SSD (gp3)
• D. Cold HDD (sc1)

Correct answer: A

Explanation

The Throughput Optimized HDD (st1) volume type is designed for workloads that require high throughput and are cost-effective for large, sequential workloads like database backups. The other options, such as Provisioned IOPS SSD (io2) and General Purpose SSD (gp3), are more expensive and offer higher performance than needed for this specific use case, while Cold HDD (sc1) is not suitable for frequent access required by backups.
