ANS-C01 Network Design Practice Question
Which THREE AWS services can be used to improve the availability of a web application across multiple AWS Regions? (Choose 3.)
⚠ Common exam trap
AWS often tests the misconception that VPC peering or Direct Connect can provide multi-Region high availability, but these services are designed for private connectivity and do not include any global traffic routing, health monitoring, or automatic failover capabilities.

Correct answer & explanation
✓
AWS Global Accelerator
AWS Global Accelerator improves availability across multiple AWS Regions by using the AWS global network to route user traffic to the optimal regional endpoint based on health, latency, and geography. It provides static anycast IP addresses and automatically reroutes traffic to healthy endpoints during a regional failure, thereby enhancing fault tolerance and performance for global web applications.
