CompTIA Cloud+ (CV0-004) — Question 36

A cloud deployment uses three different VPCs. The subnets on each VPC need to communicate with the others over private channels. Which of the following will achieve this objective?

Answer options

• A. Deploying a load balancer to send traffic to the private IP addresses
• B. Creating peering connections between all VPCs
• C. Adding BGP routes using the VPCs’ private IP addresses
• D. Establishing identical routing tables on all VPCs

Correct answer: B

Explanation

The correct answer is B, as creating peering connections allows for direct communication between the VPCs over private channels. The other options do not facilitate direct VPC communication: a load balancer (A) is not designed for VPC interconnectivity, BGP routes (C) require additional configurations and do not directly link VPCs, and identical routing tables (D) alone won't establish communication without peering.
