AWS Certified Solutions Architect – Professional — Question 657

A United Kingdom (UK) company recently completed a successful proof of concept in Amazon WorkSpaces. The company also has a large office in the United
States (US). Staff members from each office regularly travel between the two locations and need access to a corporate WorkSpace without any reconfiguration of their WorkSpaces client.
The company has purchased a domain by using Amazon Route 53 for the connection alias. The company will use a Windows profile and document management solution.
A solutions architect needs to design the full solution. The solution must use a configuration of WorkSpaces in two AWS Regions and must provide Regional resiliency.
Which solution will meet these requirements?

Answer options

• A. Create a connection alias in a UK Region and a US Region. Associate the connection alias with a directory in the UK Region. Configure the DNS service for the domain in the connection alias. Configure a geolocation routing policy. Distribute the connection string to the WorkSpaces users.
• B. Create a connection alias in a UK Region. Associated the connection alias with a directory in the UK Region. Configure the DNS service for the domain in the connection alias. Configure a weighted routing policy, with the UK Region set to 1 and a US Region set to 255. Distribute the connection string for the UK Region to the WorkSpaces users.
• C. Create a connection alias in a UK Region and a US Region. Associate the connection aliases with a directory in each Region. Configure the DNS service for the domain in the connection alias. Configure a geolocation routing policy. Distribute the connection string to the WorkSpaces users.
• D. Create a connection alias in a US Region. Associated the connection alias with a directory in the UK Region. Configure the DNS service for the domain in the connection alias. Configure a multivalue answer routing policy. Distribute the connection string for the US Region to the WorkSpaces users.

Correct answer: C

Explanation

To achieve Regional resiliency and a seamless user experience across UK and US locations without client reconfiguration, Amazon WorkSpaces Multi-Region Resilience relies on connection aliases. Creating a connection alias in both the UK and US Regions and associating them with a directory in each respective Region allows Route 53 to direct traffic dynamically. Using Route 53 with a geolocation routing policy ensures that traveling users are automatically routed to the closest AWS Region based on their physical location, while the profile/document management solution handles user data synchronization between regions.
