AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

SaaS engineers share a 40-TB Amazon EFS Standard file system mounted by EC2 instances in two AZs. Roughly 90% of the data is rarely read each year; the remaining 10% must stay low-latency. They must cut storage cost, keep the same multi-AZ resilience, and avoid application changes. Which solution is MOST cost-effective?

  • Create an Amazon EFS One Zone-IA file system and move cold files to it with an automated script.

  • Enable EFS lifecycle management to transition files idle for 30 days to the EFS Standard-Infrequent Access storage class and leave active files in EFS Standard.

  • Migrate the file system to Amazon FSx for Lustre with an S3 data repository and enable auto-release after 30 days of inactivity.

  • Use AWS DataSync to copy files older than 30 days to an S3 Glacier Deep Archive bucket and delete them from EFS.
