AWS Certified Database – Specialty — Question 73

A company's database specialist disabled TLS on an Amazon DocumentDB cluster to perform benchmarking tests. A few days after this change was implemented, a database specialist trainee accidentally deleted multiple tables. The database specialist restored the database from available snapshots. An hour after restoring the cluster, the database specialist is still unable to connect to the new cluster endpoint.
What should the database specialist do to connect to the new, restored Amazon DocumentDB cluster?

Answer options

• A. Change the restored cluster's parameter group to the original cluster's custom parameter group.
• B. Change the restored cluster's parameter group to the Amazon DocumentDB default parameter group.
• C. Configure the interface VPC endpoint and associate the new Amazon DocumentDB cluster.
• D. Run the syncInstances command in AWS DataSync.

Correct answer: A

Explanation

The correct answer is A because restoring the cluster likely requires it to use the same parameter settings as the original to function correctly, especially if TLS was previously disabled. Options B, C, and D would not address the specific need to revert to the original configuration, which is essential for proper connectivity.
