[All Professional Cloud Architect Questions]

Mountkirk Games has deployed their new backend on Google Cloud Platform (GCP). You want to create a through testing process for new versions of the backend before they are released to the public. You want the testing environment to scale in an economical way. How should you design the process?

A. Create a scalable environment in GCP for simulating production load
B. Use the existing infrastructure to test the GCP-based backend at scale
C. Build stress tests into each component of your application using resources internal to GCP to simulate load
D. Create a set of static environments in GCP to test different levels of load ג€" for example, high, medium, and low

A is correct because simulating production load in GCP can scale in an economical way. B is not correct because one of the pain points about the existing infrastructure was precisely that the environment did not scale well. C is not correct because it is a best practice to have a clear separation between test and production environments. Generating test load should not be done from a production environment. D is not correct because Mountkirk Games wants the testing environment to scale as needed. Defining several static environments for specific levels of load goes against this requirement.

C option doesn't mention if that takes production load.

Selected Answer: C

People are saying that test and production environments must be separate, and that's correct, but I don't see where in C it's speaking about the production environment. It's speaking about stress testing each component by itself to see if it's able to handle the expected load. So I'm sticking with C.

Not sure why C is not correct. That is the approach for testing an app in a non-prod environment.

IMHO it is not correct because it is testing individual components.

I think the same. People are saying that test and production environments must be separate, and that's correct, but I don't see where in C it's speaking about the production environment. It's speaking about stress testing each component by itself to see if it's able to handle the expected load.

The correct answer is A: Create a scalable environment in GCP for simulating production load. To create a thorough testing process for new versions of the backend before they are released to the public, it's important to simulate production load in the testing environment. This will help ensure that the backend can handle the expected volume of users and scale appropriately. One way to do this is to create a scalable environment in GCP that can simulate production load. This could involve using GCP services such as Google Compute Engine or Google Kubernetes Engine to spin up multiple virtual machines or containers to simulate a high volume of requests and traffic. This approach will allow you to test the backend at scale and ensure that it can handle the expected load.

Using the existing infrastructure to test the GCP-based backend at scale may not be feasible, as the existing infrastructure may not be capable of simulating the expected production load. Building stress tests into each component of the application using internal GCP resources could be time-consuming and may not provide a realistic simulation of production load. Creating a set of static environments in GCP to test different levels of load may not be sufficient for testing the backend at scale, as the load may not be consistent with what is expected in production.
