Question 780
Two VPCs need private communication and their CIDR blocks do not overlap. Which ongoing practice BEST sustains the intended result?
Explanation
Correct Answer
Document CIDR compatibility and routing before creating more peers. This continuing control fits because VPC peering directly connects VPC networks but does not automatically make peering transitive. The associated appropriate response is: Consider VPC peering for supported private communication between the two VPCs. An observable check is: A test VM accesses an authorized private endpoint across the peering connection.
Incorrect Answers
A public IP by itself does not replace the required VPC Internet routing path. In this question, however, vPC peering directly connects VPC networks but does not automatically make peering transitive. The answer that meets the requirement is: Document CIDR compatibility and routing before creating more peers.
Network ACLs are stateless subnet controls, distinct from resource-level security groups. In this question, however, vPC peering directly connects VPC networks but does not automatically make peering transitive. The answer that meets the requirement is: Document CIDR compatibility and routing before creating more peers.
CloudFront caches eligible content at edge locations to reduce origin fetch distance. In this question, however, vPC peering directly connects VPC networks but does not automatically make peering transitive. The answer that meets the requirement is: Document CIDR compatibility and routing before creating more peers.
