JNCIA-Junos: Juniper Networks Certified Associate – Junos (2022) — Question 17

What are two benefits of a modular operating system? (Choose two.)

Answer options

• A. Each module runs in its own protected memory space
• B. It enables the independent restart of each module as necessary
• C. A malfunction in one module causes a full system shutdown
• D. It enables CPU scheduling strictly using kernel system calls

Correct answer: A, B

Explanation

The correct answers, A and B, highlight that each module operates independently in its own memory space, which enhances security and stability, and can be restarted without affecting the entire system. Option C is incorrect because a modular design aims to contain failures and prevent full system shutdowns, while option D is misleading as it suggests a limitation that doesn't apply to modular systems.
