AWS Certified Solutions Architect – Professional (SAP-C02) — Question 477

A company recently completed a successful proof of concept of Amazon WorkSpaces. A solutions architect needs to make the solution highly available across two AWS Regions. Amazon WorkSpaces is deployed in a failover Region, and a hosted zone is deployed in Amazon Route 53.

What should the solutions architect do to configure high availability for the solution?

Answer options

• A. Create a connection alias in the primary Region and in the failover Region. Associate the connection aliases with a directory in each Region. Create a Route 53 failover routing policy. Set Evaluate Target Health to Yes.
• B. Create a connection alias in the primary Region and in the failover Region. Associate the connection aliases with a directory in the primary Region. Create a Route 53 multivalue answer routing policy.
• C. Create a connection alias in the primary Region. Associate the connection alias with a directory in the primary Region. Create a Route 53 weighted routing policy.
• D. Create a connection alias in the primary Region Associate the connection alias with a directory in the failover Region. Create a Route 53 failover routing policy. Set Evaluate Target Health to Yes.

Correct answer: A

Explanation

To configure multi-region disaster recovery for Amazon WorkSpaces, connection aliases must be created in both the primary and failover Regions and associated with the respective local directories. Route 53 failover routing with Evaluate Target Health enabled is then used to automatically redirect client connections to the standby Region if the primary Region becomes unhealthy. Other options are incorrect because they do not map aliases to both directories or they use incorrect routing policies like weighted or multivalue routing.
