Question

A company’s AWS environment has two VPCs. VPC A has a CIDR block of 192.168.0.0/16. VPC B has a CIDR block of 10.0.0.0/16. Each VPC is deployed in a separate AWS Region. The company has remote users who work outside the company’s offices. These users need to connect to an application that is running in the VPCs.

Traffic to and from the VPCs over the internet must be encrypted. A network engineer must set up connectivity between the remote users and the VPCs.

Which combination of steps should the network engineer take to meet these requirements with the LEAST management overhead? (Choose three.)

A. Establish an AWS Site-to-Site VPN connection between VPC A and VPC B.
B. Establish a VPC peering connection between VPC A and VPC B.
C. Create an AWS Client VPN endpoint in VPC A and VPC B Add an authorization rule to grant access to VPC A and VPC B.
D. Create an AWS Client VPN endpoint in VPC A Add an authorization rule to grant access to VPC A and VPC B.
E. Add a route to the AWS Client VPN endpoint’s route table to direct traffic to VPC B.
F. Add a route to the AWS Client VPN endpoint’s route table to direct traffic to VPC A.

Answer

C. Create an AWS Client VPN endpoint in VPC A and VPC B Add an authorization rule to grant access to VPC A and VPC B.
E. Add a route to the AWS Client VPN endpoint’s route table to direct traffic to VPC B.
F. Add a route to the AWS Client VPN endpoint’s route table to direct traffic to VPC A.

Explanation

These steps minimize management overhead:

C – Single Client VPN endpoint per VPC handles remote access rather than a connection between VPCs

E/F – Routes added per VPC for remote access rather than complex network interconnect

Compared to other options:

A/B – Full VPN or peering between VPCs adds ongoing management of interconnect
D – Incomplete, missing routing steps

By leveraging Client VPN endpoints with authorization and routing per VPC, remote access can be supported across both VPCs with minimal interconnect setup or ongoing management.
