Q30 — AWS DOP-C02 Ch.2

Question 30 of 100 | ← Chapter 2

A company uses AWS Storage Gateway in file gateway mode across multiple resources with Amazon S3 buckets. At the start of business each morning, users cannot see objects processed overnight by a third party. When a DevOps engineer directly inspects the S3 buckets, the data is present, but it is missing in Storage Gateway. Which solution ensures updated third-party files are available each morning?

• A. Configure an Amazon EventBridge rule to run nightly and invoke an AWS Lambda function to execute the RefreshCache command on Storage Gateway. ✓
• B. Instruct the third party to use AWS Transfer for SFTP to place data into the S3 buckets.
• C. Modify Storage Gateway to run in volume gateway mode.
• D. Use S3 Same-Region Replication to replicate any changes made directly to the S3 bucket into Storage Gateway.

Correct Answer: A. Configure an Amazon EventBridge rule to run nightly and invoke an AWS Lambda function to execute the RefreshCache command on Storage Gateway.

Explanation

Option A is correct. Configuring a nightly Amazon EventBridge rule to invoke an AWS Lambda function that runs the RefreshCache command ensures Storage Gateway’s cache is updated promptly, enabling users to see third-party objects processed overnight. Option B—using AWS Transfer for SFTP—does not resolve the Storage Gateway caching issue. Option C—switching to volume gateway mode—does not specifically address this display inconsistency. Option D—S3 Same-Region Replication—cannot guarantee timely visibility in Storage Gateway at morning start-of-business. Thus, option A is the appropriate solution.
