Domain 3.5: Cost Optimization — AWS SAP-C02 Practice Question 49

How to approach this question

Identify the free VPC feature that routes traffic to S3 and DynamoDB.

Full Answer

A.Create Gateway VPC Endpoints for Amazon S3 and Amazon DynamoDB in the VPC and update the route tables.✓ Correct

Create Gateway VPC Endpoints for Amazon S3 and Amazon DynamoDB in the VPC and update the route tables.

NAT Gateways incur an hourly charge and a data processing charge per gigabyte. If your EC2 instances are transferring large amounts of data to S3 or DynamoDB through a NAT Gateway, your costs will be high. By creating Gateway VPC Endpoints for S3 and DynamoDB, the traffic is routed directly over the AWS network. Gateway endpoints are completely free, eliminating the NAT Gateway data processing costs for this traffic.

Common mistakes

Choosing Interface Endpoints, which cost money, instead of the free Gateway Endpoints.
