Question 30
Two VPCs need private communication and their CIDR blocks do not overlap. Which high-level AWS choice is MOST suitable for the business need?
Explanation
Correct Answer
Consider VPC peering for supported private communication between the two VPCs. This choice addresses the specific business requirement: VPC peering directly connects VPC networks but does not automatically make peering transitive. A clear way to confirm success is: A test VM accesses an authorized private endpoint across the peering connection. To sustain the result: Document CIDR compatibility and routing before creating more peers.
