JNCIA-Junos: Juniper Networks Certified Associate – Junos — Question 3

When a system process encounters an error, how does the Junos OS protect other processes from being impacted?

Answer options

• A. Each process operates in its own shared memory space.
• B. The Junos OS executes only one process at a time.
• C. Each routing protocol runs as an individual process.
• D. The Junos OS executes multiple processes simultaneously.

Correct answer: A

Explanation

The correct answer is A because each process in the Junos OS is designed to operate in its own isolated memory space, preventing an error in one from affecting others. Option B is incorrect as the Junos OS is capable of multitasking, while option C, although true, does not address the protection mechanism, and option D is inaccurate in the context of error isolation.
