JNCIA-Junos: Juniper Networks Certified Associate – Junos (2024) — Question 64

What are two advantages of using the Junos OS? (Choose two.)

Answer options

• A. It enables you to roll back to a previous configuration.
• B. It supports up to a maximum of two previous configurations.
• C. It pushes your configuration changes “live” immediately.
• D. It is modular.

Correct answer: A, D

Explanation

The correct answers are A and D because Junos OS allows for configuration rollback, providing flexibility in managing network settings, and is designed with a modular architecture that enhances its functionality. Option B is incorrect as Junos OS supports more than two previous configurations, and option C is misleading because while changes can be applied quickly, they are not necessarily 'live' in the sense that they cannot be reverted without proper procedures.
