ANS-C01 Network Implementation Practice Question
A company wants to securely connect two VPCs in different AWS regions using AWS infrastructure. Which service should be used?
⚠ Common exam trap
A common mix-up: candidates choose AWS Transit Gateway because they think it is required for inter-region connectivity, but they overlook that VPC peering directly supports cross-region connections and is the simpler, more cost-effective option for a two-VPC scenario.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VPC peering
VPC peering is the correct service because it allows direct, private connectivity between two VPCs in different AWS regions using AWS's internal network, without traversing the public internet. It uses the existing AWS infrastructure to route traffic between the VPCs via private IP addresses, and it supports inter-region peering as of 2017, making it the simplest and most cost-effective solution for this specific requirement.
