AWS Certified Cloud Practitioner — Question 13

A pharmaceutical company operates its infrastructure in a single AWS Region. The company has thousands of VPCs in a various AWS accounts that it wants to interconnect.
Which AWS service or feature should the company use to help simplify management and reduce operational costs?

Answer options

• A. VPC endpoint
• B. AWS Direct Connect
• C. AWS Transit Gateway
• D. VPC peering

Correct answer: C

Explanation

The correct answer is AWS Transit Gateway as it enables the interconnection of multiple VPCs and on-premises networks, simplifying management and reducing costs by centralizing connectivity. VPC endpoints and VPC peering are limited in scope and do not provide the same level of efficiency for multiple connections, while AWS Direct Connect is primarily used for dedicated network connections rather than VPC interconnectivity.
