AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 59

A company has deployed its SAP applications into multiple Availability Zones in the same AWS Region. To accommodate storage of media files, database table export and import, and files dropped by third-party tools, the company has mounted Amazon Elastic File System (Amazon EFS) file systems between the SAP instances. The company needs to retrieve the files quickly for installations, updates, and system refreshes.
Over time, the EFS file systems have grown exponentially to multiple terabytes. An SAP solutions architect must optimize storage cost for the files that are stored in Amazon EFS.
Which solution will meet this requirement with the LEAST administrative overhead?

Answer options

• A. Scan the files manually to identify unnecessary files. Delete the unnecessary files.
• B. Move the files to Amazon S3 Glacier Deep Archive.
• C. Apply a lifecycle policy on the files in Amazon EFS to move the files to EFS Standard-Infrequent Access (Standard-IA).
• D. Move the files to Amazon S3 Glacier. Apply an S3 Glacier vault lock policy to the files.

Correct answer: C

Explanation

The correct answer is C because applying a lifecycle policy to move files to EFS Standard-IA optimizes costs while allowing for quick access when needed. Option A involves manual intervention, which increases administrative overhead. Option B and D suggest moving files to S3 Glacier, which is cheaper but does not provide the necessary quick access required for installations and updates.
