A. B. C. D.

Answer - B.

The AWS documentation mentions the following.

Amazon WorkSpaces launches your WorkSpaces in a virtual private cloud (VPC)

If you use AWS Directory Service to create a Microsoft AD or a Simple AD, we recommend that you configure the VPC with one public subnet and two private subnets.

Configure your directory to launch your WorkSpaces in the private subnets.

When working with AWS Workspaces, it is recommended to have one private and one public subnet (Option A).

AWS Workspaces is a fully managed, secure Desktop-as-a-Service (DaaS) solution that enables users to access their desktops and applications from anywhere, anytime, and on any device. To deploy AWS Workspaces, you need to create a VPC (Virtual Private Cloud) and configure subnets to launch the Workspaces instances.

Subnets are logical divisions of a VPC's IP address range that allow you to isolate and secure your resources. When creating subnets for AWS Workspaces, you need to consider the following:

  • Public vs. private subnets: Public subnets have a direct route to the Internet, while private subnets do not. AWS Workspaces instances require access to the Internet to download updates, patches, and licenses, but you want to limit external access to your instances to minimize security risks. Therefore, it is recommended to have one public subnet to provide Internet access and one private subnet to launch your Workspaces instances.

  • Availability Zones: AWS Workspaces instances can be launched in multiple Availability Zones (AZs) for high availability and fault tolerance. You should create subnets in each AZ where you plan to launch Workspaces instances.

  • IP address range: Each subnet has a CIDR (Classless Inter-Domain Routing) block that defines the IP address range of the subnet. You should choose a CIDR block that provides enough IP addresses to accommodate your Workspaces instances and any additional resources that require access to the subnet.

  • Route tables and network access control lists (ACLs): You need to configure route tables and network ACLs to control the traffic flow in and out of your subnets. For example, you need to allow inbound and outbound traffic to and from the Internet in the public subnet, but you may want to restrict inbound traffic to the private subnet to a specific IP address range or port.

Based on these considerations, the recommended configuration for subnets in AWS Workspaces is to have one public and one private subnet. Option A is the correct answer. Option B and D have too many subnets, which can increase the complexity and cost of your network setup. Option C has two public subnets, which can expose your instances to unnecessary security risks.
