Free AWS DVA-C02 Actual Exam Questions - Question 10 Discussion
show the weather forecast for one of the company's office locations. The application will provide a
REST endpoint that clients can call. Where possible, the application should use caching features
provided by AWS to limit the number of requests to the backend service. The application backend
will receive a small amount of traffic only during testing.
Which approach should the developer take to provide the REST endpoint MOST cost-effectively?
This is definitely a light workload, so spinning up containers with EKS or ECS seems overkill. Lambda plus API Gateway caching (B) keeps things simple and cheap without extra management overhead. B
I think A, C, and D all involve more infrastructure than needed for just a small POC with low traffic. Lambda plus API Gateway caching in B seems the simplest and cheapest way to go here. B
This is definitely a low-traffic test, so spinning up a whole container cluster feels like overkill. B makes the most sense with Lambda and API Gateway handling caching without extra costs. Option B.
Maybe B makes the most sense here. Lambda with API Gateway is usually the cheapest for small traffic, and API Gateway can handle caching to reduce backend calls. The other options seem like overkill for just a simple weather forecast POC. Using containers or Beanstalk would cost more and be more complex. Not sure why option D mentions Lambda behind an ALB though-that sounds odd. Overall, I’d go with B unless I’m missing something about the caching part being better elsewhere.
