Step-by-Step Solution
Solution:
Step 1: Understand VPC endpoint routing
With a VPC endpoint, traffic to DynamoDB stays within the AWS network and uses the endpoint instead of the internet.Step 2: Apply to EC2 inside VPC scenario
Requests from EC2 inside the VPC use the VPC endpoint to reach DynamoDB privately without internet or NAT.Final Answer:
The request is routed through the VPC endpoint directly to DynamoDB -> Option AQuick Check:
Network path with VPC endpoint = Private route [OK]
Quick Trick: VPC endpoint routes traffic privately inside AWS [OK]
Common Mistakes:
MISTAKES- Assuming traffic goes through internet gateway
- Thinking NAT gateway is required
- Believing VPC endpoints block DynamoDB access
