AWS Certified Advanced Networking – Specialty (ANS-C01) — Question 112

A company is migrating applications from a data center to AWS. Many of the applications will need to exchange data with the company's on-premises mainframe.

The company needs to achieve 4 Gbps transfer speeds to meet peak traffic demands. A network engineer must design a highly available solution that maximizes resiliency. The solution must be able to withstand the loss of circuits or routers.

Which solution will meet these requirements?

Answer options

• A. Order four 10 Gbps AWS Direct Connect connections that are evenly spread over two locations. Terminate one connection from each Direct Connect location to a router at the company location. Terminate the other connection from each Direct Connect location to a different router at the company location.
• B. Order two 10 Gbps AWS Direct Connect connections that are evenly spread over two locations. Terminate the connection from each Direct Connect location to a different router at the company location.
• C. Order four 1 Gbps AWS Direct Connect connections that are evenly spread over two locations. Terminate one connection from each Direct Connect location to a router at the company location. Terminate the other connection from each Direct Connect location to a different router at the company location.
• D. Order two 1 Gbps AWS Direct Connect connections that are evenly spread over two locations. Terminate the connection from each Direct Connect location to a different router at the company location.

Correct answer: A

Explanation

Option A is the correct answer as it provides a total of 40 Gbps bandwidth, meeting the required 4 Gbps transfer speed while ensuring high availability and resilience through multiple connections and routers. Options B and D do not provide sufficient bandwidth, while Option C offers only 4 Gbps total, which is inadequate for the peak demands stated.
