JNCIA-Junos: Juniper Networks Certified Associate – Junos (2022) — Question 31

You loaded the factory-default configuration on your Junos device. Which single element must be configured before a commit command will succeed?

Answer options

• A. An IPv4 address must be configured on the fxp0 or em0 interface
• B. A hostname must be configured
• C. A root password must be configured
• D. An IPv4 default route must be configured

Correct answer: C

Explanation

The correct answer is C because a root password is a mandatory requirement for committing configuration changes in Junos. Options A, B, and D, while important for network functionality and identification, do not prevent the commit command from succeeding if the root password has not been set.
