Discuss PeopleCert DevOps-SRE Exam Topic 8 Question 65

Microservices are independent services that are developed, deployed, and maintained separately.

Which of the following BEST justifies the use of this application architecture?

AModernizing and refactoring legacy applications

BModernizing the user interface of the core system

CCreating a simple, lightweight business application

DBuilding a basic product fast, as a proof of concept

Suggested Answer: A

Comprehensive and Detailed Explanation From Exact Extract:

SRE supports microservices architecture because it improves reliability by reducing blast radius, allowing independent deployments, and enabling scalable autonomous teams. The SRE Book notes: ''Microservices enable teams to independently iterate and improve reliability without the constraints of large monolithic systems.'' (SRE Book -- Distributed Systems). One of the strongest reasons to adopt microservices is modernizing and refactoring large legacy monoliths, allowing them to be broken into independently deployable, maintainable components.

Option A is therefore the best justification.

Options B, C, and D may involve architectural choices, but they do not explain why microservices are the preferred architecture for reliability and scalability.

Thus, A is correct.

C seems too simple. Microservices are for complex systems.

Wait, can microservices really help with UI modernization? Seems off.

Raina 3 months ago

I think D) makes sense too, especially for quick prototypes.

Karol 3 months ago

A) is definitely the best choice for microservices!

Lauran 4 months ago

I lean towards A as well, but I wonder if C could apply in some cases where simplicity is key.

Serina 5 months ago

I practiced a question similar to this, and I think D makes sense for quick iterations, but it doesn't really capture the essence of microservices.

Felicia 5 months ago

I'm not entirely sure, but I feel like B could also be relevant since a better UI might need a different architecture.

Roxane 5 months ago

I remember we discussed how microservices help with modernizing legacy systems, so I think A might be the right choice.
