Juniper JN0-224 Exam - Topic 3 Question 5 Discussion

Actual exam question for Juniper's JN0-224 exam
Question #: 5
Topic #: 3
[All JN0-224 Questions]

You are asked to write an on-box script that will be triggered when a specific interface on a Junos device goes down.

Which type of on-box script should you use to accomplish this task?

Show Suggested Answer Hide Answer
Suggested Answer: B

An event script is used to automate responses to system events in Junos, such as an interface going down. These scripts are triggered automatically when a specified event occurs, making them suitable for tasks like monitoring interface status and executing actions when the status changes.

Option B (event) is correct because event scripts are designed for reacting to system events like an interface going down.

Option A (commit) is used for configuration changes, Option C (operation) is used for operational tasks, and Option D (SNMP) is not applicable in this context.

Haha, B) event is the way to go. Unless you want your script to just sit there and do nothing when the interface goes down.

Could it be an operation script? I just can't recall if those are for monitoring or something else.

I think we need to use an event script since it handles interface state changes, right?

Ugh, I'm drawing a blank on the different Junos script types. I better quickly refresh my memory before I attempt to answer this.

I'm feeling pretty confident about this one. The question is asking for a script to run when an interface goes down, so the event-based script is the clear choice.
