Amazon ANS-C01 Exam - Topic 3 Question 74 Discussion

Question

A company has users who work from home. The company wants to move these users to Amazon WorkSpaces for additional security visibility.

The company has deployed WorkSpaces in its own AWS account in VPC A. A network engineer decides to provide the security visibility by using two firewall appliances behind a Gateway Load Balancer (GWLB). The network engineer provisions another VPC, VPC B, in a separate account and deploys the two firewall appliances in separate Availability Zones.

What should the network engineer do to configure the network connectivity for this solution?

B) Create a GWLB in VPC B with the firewall appliance instances as targets. Use the GWLB to create a GWLB endpoint. Add the AWS principal ARN of the WorkSpaces account to the principal allow list of the GWLB endpoint. In the WorkSpaces account, create a VPC endpoint and specify the service name that the AWS Management Console provides for the GWLB endpoint. Modify the route tables of VPC A to point the default route to the GWLB endpoint.
