AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 220

You wish to access all European regions using your Direct Connect connection. How should you accomplish this?

Answer options

• A. Peer VPCs in the different regions and connect DX to one of the regions to communicate with the other.
• B. Use a DX Gateway.
• C. Find the prefix list for the other region and add it to your route table.
• D. One DX connection will connect you to all regions.

Correct answer: B

Explanation

The correct answer is B, as a DX Gateway is specifically designed to connect to multiple regions and facilitate access across them. Option A is incorrect because peering VPCs does not inherently provide access to all regions. Option C is not sufficient as merely adding a prefix list does not establish a connection to other regions. Option D is misleading, as a single DX connection does not automatically connect to all regions without a proper gateway setup.
