Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 36

Which statement about microservices architecture is true?

Answer options

• A. Applications are written in a single unit.
• B. It is a complex application composed of multiple independent parts.
• C. It is often a challenge to scale individual parts.
• D. A single faulty service can bring the whole application down.

Correct answer: B

Explanation

Option B is correct as microservices architecture consists of multiple independent components that work together to form a complex application. Option A is incorrect because microservices are not written as a single unit but rather as separate services. Option C is also not entirely accurate since while scaling can be challenging, it is one of the advantages of microservices. Option D is misleading because proper microservices design includes fault tolerance to prevent a single service failure from affecting the entire application.
