https://docs.aws.amazon.com/workspaces/latest/adminguide/cross-region-redirection.html#cross-region-redirection-create-connection-aliases Using the same AWS account, create connection aliases in each primary and failover Region where you want to set up cross-Region redirection.

A is right Creating connection aliases in both Regions ensures that users can access the WorkSpaces instance from either region. Associating the connection aliases with directories in each Region allows for load balancing and redirection of traffic between the two Regions. Creating a Route 53 failover routing policy enables Amazon Route 53 to direct users from the primary Region to the failover Region if there's an issue with the primary Region. Setting Evaluate Target Health to Yes ensures that Route 53 continuously monitors the health of the WorkSpaces instance in both Regions and directs traffic accordingly.

By following Option A, you can achieve high availability for your Amazon WorkSpaces solution across two AWS Regions, with automatic failover and health monitoring provided by the Route 53 failover routing policy and connection aliases associated with WorkSpaces directories in each Region. The other options are either incomplete or incorrect: Option B (multivalue answer routing policy) is not suitable for failover scenarios, as it distributes traffic across multiple resources simultaneously, rather than failing over to a secondary resource when the primary becomes unavailable. Option C (weighted routing policy) is used for distributing traffic based on predefined weights, but it does not provide automatic failover capabilities based on health checks. Option D is incorrect because it associates the connection alias with the failover Region's directory, which would make the failover Region the primary deployment, defeating the purpose of having a failover configuration.

"You can associate a connection alias with ONLY ONE directory per AWS Region." So, it can't be D.

For A: Potential latency increase due to cross-region access For B:Potential data consistency issues if failover occurs I choose A

A is correct

I will go with option A

A for sure

Answer is A - 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.

A https://docs.aws.amazon.com/ja_jp/workspaces/latest/adminguide/cross-region-redirection.html

Believe the answer is A becuase the two distinct Workspaces directories would give you two IP's for truc failover
