AWS Certified Solutions Architect – Professional SAP-C01 – Question814

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?

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.
