Question

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?

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.

Answer

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.

Explanation

This provides:

  • 4 x 10Gbps = 40Gbps total bandwidth to meet 4Gbps requirements with overhead
  • Connections distributed across 2 locations for resiliency if a location fails
  • Connections terminated across multiple routers within each location for resiliency if a router fails

Options B, C and D do not meet the 4Gbps throughput requirement.

Only option A provides the necessary bandwidth and level of resiliency/redundancy by distributing 4 high-capacity connections across multiple locations and routers.
