Reply To: Review Set 2 – VPC peering cfgs – route to specific addresses.

[Neil-TutorialsDojo]

Hello AudreyST,

Good day!

Thank you for your question.

The /16 CIDR block represents the entire address range for the VPC. Using /16
in the route table ensures that all IP addresses within VPC-A are reachable from VPC-B and VPC-C. In contrast, the /24 CIDR block used for Subnet-A specifies a smaller, specific address range within VPC-A.

Both approaches for routing are correct based on the given scenario, and the choice depends on whether you need to target specific subnets or the entire VPC.

I understand the confusion and apologize for any misunderstanding this may have caused. We will update the question as soon as possible.

Thank you for bringing this to our attention!

Regards,
Neil @ tutorials dojo
