JNCIA-DC: Juniper Networks Certified Associate – Data Center (2023) — Question 5

Which statement about microservices is correct?

Answer options

• A. Microservices are developed as a suite of applications and rely on developers to deliver updates to the entire suite at once.
• B. Microservices must share a common database to ensure data integrity.
• C. Microservices are designed to be dependent on each other to ensure that if one process fails, the remaining processes will not continue to operate.
• D. Microservices communicate with each other using APIs.

Correct answer: D

Explanation

The correct answer is D because microservices are designed to interact with each other through APIs, enabling independent deployment and scalability. Options A, B, and C incorrectly describe microservices as being reliant on a singular suite, sharing a database, or being dependent on each other, which contradicts the principles of microservices architecture that promote independence and modularity.
