AWS Certified SysOps Administrator – Associate (legacy) — Question 360

A user has scheduled the maintenance window of an RDS DB on Monday at 3 AM. Which of the below mentioned events may force to take the DB instance offline during the maintenance window?

Answer options

• A. Enabling Read Replica
• B. Making the DB Multi AZ
• C. DB password change
• D. Security patching

Correct answer: D

Explanation

The correct answer is D, as applying security patches often requires a restart of the DB instance, which would take it offline. Enabling Read Replica, making the DB Multi AZ, and changing the DB password typically do not necessitate taking the DB instance offline.
