Amazon ANS-C01 Exam - Topic 4 Question 13 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 13
Topic #: 4

A bank built a new version of its banking application in AWS using containers that content to an on-premises database over VPN connection. This application version requires users to also update their client application. The bank plans to deprecate the earlier client version. However, the company wants to keep supporting earlier clients through their on-premises version of the application to serve a small portion of the customers who haven't yet upgraded.

What design will allow the company to serve both newer and earlier clients in the MOST efficient way?

AUse an Amazon Route 53 multivalue answer routing policy to route older client traffic to the on-premises application version and the rest of the traffic to the new AWS based version.

BUse a Classic Load Balancer for the new application. Route all traffic to the new application by using an Elastic Load Balancing (ELB) load balancer DNS. Define a user-agent-based rule on the backend servers to redirect earlier clients to the on-premises application.

CUse an Application Load Balancer for the new application. Register both the new and earlier applications as separate target groups and use path-based routing to route traffic based on the application version.

DUse an Application Load Balancer for the new application. Register both the new and earlier application backends as separate target groups. Use header-based routing to route traffic based on the application version.

Classic Load Balancer? That's so outdated, B isn't the way to go.

A multivalue routing policy could work, but it might complicate things.

Wait, can we really support both versions like this? Sounds tricky.

I disagree, D seems more flexible with header-based routing.

I think option C is the best choice for efficient routing.

I feel like header-based routing might be the most flexible option since it allows for more specific control over which clients get routed where, but I need to double-check the requirements.

I practiced a similar question where we had to route traffic based on user agents. I wonder if using a user-agent-based rule would be efficient enough for this case.

I think using an Application Load Balancer with path-based routing could work, but I'm a bit confused about how to implement that with the different client versions.

I remember studying about load balancers, but I'm not sure if Classic Load Balancer is the best choice here since it seems outdated for this scenario.

This seems like a pretty straightforward question. I think the answer is B - "Very small disbursements" since the question mentions employees trying to keep the sizes of the disbursements low to avoid detection.

It seems like all the examples we went through had five-digit numbers; I hope that's the case here too!

I vaguely remember something about Catalyst 3560-CX being discussed in our practice sessions, but the other option is tricky.

Hmm, I'm not entirely sure about this one. The question mentions that items deleted from removable media aren't stored in the Recycle Bin, so that's an important detail to keep in mind. I'll need to think this through carefully.

I think establishing operations are related to how the environment affects reinforcement, but I'm not sure which option specifically explains that.
