Your company is planning to try out AWS Workspaces for 100 users. They want to have a standalone managed directory service along with AWS workspaces. Which of the following would be the ideal option that will have the least administrative overhead and also be cost-effective?

Answer options:

A.Deploy an AD domain server in a VPC and configure AWS Workspace to use the newly created AD Domain server.
B.Choose an AD connector to use along with AWS Workspaces.
C.Choose Simple AD to use along with AWS Workspaces.
D.Choose AWS Directory Service to use along with AWS Workspaces.

Answer – C
The AWS Documentation mentions the following.
Amazon WorkSpaces uses directories to store and manage information for your WorkSpaces and users. For your directory, you can choose from Simple AD, AD Connector, or AWS Directory Service for Microsoft Active Directory (Enterprise Edition), also known as Microsoft AD. In addition, you can establish a trust relationship between your Microsoft AD directory and your on-premises domain.
Option A is incorrect because this would require more effort.
Option B is incorrect because there is a requirement for a standalone managed directory service. Simple AD would be the best fit here.
Option D is incorrect because this would not be cost-effective.
