AWS Certified Database – Specialty — Question 249

An ecommerce company uses an Amazon Aurora MySQL DB cluster to process payments. The company’s database specialist notices that Aurora performs database maintenance actions periodically. The database specialist is concerned because the upcoming maintenance window conflicts with a company sales event.

What should the database specialist do to address this concern with the LEAST operational effort?

Answer options

• A. Add a new Aurora Replica so that the maintenance action occurs on the Aurora Replica first.
• B. Defer the maintenance action in the AWS Management Console or by using the AWS CLI.
• C. Delete the maintenance action in the AWS Management Console or by using the AWS CLI.
• D. Add a new Aurora standby DB instance so that the maintenance action occurs on the standby DB instance first.

Correct answer: B

Explanation

The correct answer is B because deferring the maintenance action allows the database specialist to avoid conflicts with the sales event with minimal effort. Adding replicas or standby instances (options A and D) involves more operational overhead and does not directly address the timing conflict. Option C is incorrect as deleting the maintenance action could lead to unaddressed issues or vulnerabilities that would arise later.
