Q4Network Design

A company is migrating applications from a data center to AWS. Many applications will need to exchange data with the company’s on-premises mainframe. The company must achieve transfer speeds of 4 Gbps to satisfy peak traffic demands. A network engineer must design a highly available solution that maximizes resiliency. The solution must withstand the loss of circuits or routers. Which solution satisfies these requirements?

I go with B, Option A suggests ordering four 10 Gbps Direct Connect connections, which may be unnecessary for achieving the required 4 Gbps transfer speeds and could increase costs without providing significant benefits.
A 6
A is the right ans
B 5
Everyone voted for answer A but the answer does not even make sense. 1) Order *four* 10 Gbps AWS Direct Connect connections that are evenly spread over two locations. 2)Terminate *one connection* (not connections) from each Direct Connect location to a router at the company location. 3) Terminate the *other connection* (didn't say connections) from each Direct Connect location to a different router at the company location. What happened to the other two Direct Connect lines that was ordered? And there's no mention of LAG either. All the best.

To achieve 4 Gbps transfer speeds with high availability and resiliency, you would typically want to aggregate multiple AWS Direct Connect connections. Option A and Option B both involve ordering multiple 10 Gbps AWS Direct Connect connections, making them potential solutions. However, Option A provides additional redundancy by terminating connections to different routers at the company location, which enhances resiliency.

My guess is that the answer lies in the following statement in the question "that maximizes resiliency" ie Maximum Resiliency DX Connection Design
A 3
maximum resiliency architecture
A 3
A network engineer MUST design a highly available solution that MAXIMIZES RESILIENCY

I re-read that answer again and it is a connection per DX location (2x) per router. So I change my answer to A to fulfil the maximum resiliency requirement of the question. All the best.

B provides high-availability and enough capacity during peaks.

You dont have to use such words in learning platform.

Option 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. It's 2 completely different circuits at 2 different locations and terminates on different routers on-prem, how does this not meet the requirements?
B 2
I think the right answer is B.

So, Answer - A -- because they checking your english again not a engineering skills. 'B' - is OPTIMIZED option. 'A' is MAXIMIZED. Question is about MXIMAZIED solution -'A network engineer must design a highly available solution that **maximizes** resiliency.

English is not my native language, but, rereading, it is in fact alternative A, I believe it refers to this doc: https://docs.aws.amazon.com/directconnect/latest/UserGuide/resiliency_toolkit.html

The correct solution is 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. This solution meets the requirements because it provides the necessary 4 Gbps transfer speed and maximizes resiliency. By spreading the Direct Connect connections over two locations and terminating them at different routers, the solution can withstand the loss of circuits or routers, ensuring high availability. Please note that the other options do not fully meet the requirements. Options B, C, and D do not provide the necessary redundancy and resiliency. Option C does not provide the required 4 Gbps transfer speed.

loved the way you explained. Agree. Based on the Question, it is asking for Maximizing resiliency.
1
A is an overkill but the question focuses on RESILIENCY. So A is the correct answer
1
I think that it's correct answer is A.
B 1
A and B meet the requirements, but I think A is over-designed. B is considered sufficient in terms of availability and fault tolerance.

If English is not your first language and you answer "B", then frankly, you are stupid.

*sorry, I meant (is) your first language. Just trying to remove the confusion, the answer is definitely (A), because the solution can withstand circuit and router failures in each location.
