AWS Certified Solutions Architect – Professional — Question 350

Your Application is not highly available, and your on-premises server cannot access the mount target because the Availability Zone (AZ) in which the mount target exists is unavailable.
Which of the following actions is recommended?

Answer options

• A. The application must implement the checkpoint logic and recreate the mount target.
• B. The application must implement the shutdown logic and delete the mount target in the AZ.
• C. The application must implement the delete logic and connect to a different mount target in the same AZ.
• D. The application must implement the restart logic and connect to a mount target in a different AZ.

Correct answer: D

Explanation

When an Availability Zone (AZ) experiences an outage, any mount target hosted within that specific AZ becomes unreachable. To handle this scenario, the application must incorporate restart logic to automatically reconnect to a functioning mount target in a different AZ. Options involving recreating or connecting to targets in the same, failed AZ will not restore connectivity.
