A company is designing a multi-region architecture with VPCs connected via VPC peering. They need to ensure high availability and low latency. Which THREE design principles should they follow? (Choose three.)
Answer choices
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
✓
Deploy redundant VPN connections to each region
Options B, D, and E are correct. Deploying redundant VPN connections ensures high availability and failover between regions. AWS Direct Connect provides consistent low-latency connectivity for inter-region traffic. Using a transit gateway simplifies inter-region peering with transitive routing and centralized management. Option A is incorrect because VPC endpoints are for accessing AWS services privately, not for inter-region connectivity. Option C is incorrect because a single NAT gateway creates a single point of failure and does not support inter-region traffic.
