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?

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:

Explanation: To make sure that there is continuous availability between your on-premises data center and your Amazon Virtual Private Cloud (VPC), it is suggested that you configure two AWS Direct Connect connections. Your application should implement restart logic and connect to a mount target in a different AZ if your application is not highly available and your on-premises server cannot access the mount target because the AZ in which the mount target exists becomes unavailable.
