Juniper JN0-351 Exam - Topic 1 Question 1 Discussion

Actual exam question for Juniper's JN0-351 exam

[All JN0-351 Questions]

You implemented the MAC address limit feature with the shutdown action on all interfaces on your switch.

In this scenario, which statement is correct when a violation occurs?

Show Suggested Answer Hide Answer
Suggested Answer: A

When the MAC address limit feature with the shutdown action is implemented on a switch, if a violation occurs, the interface is disabled and a system log entry is generated1.If the switch has been configured with the port-error-disable statement, the disabled interface recovers automatically upon expiration of the specified disable timeout1.However, if the switch has not been configured for auto-recovery from port error disabled conditions, you must manually clear the violation by running the clear ethernet-switching port-error command for the interface to send and receive traffic again1.This explanation is based on the Enterprise Routing and Switching Specialist (JNCIS-ENT) documents and learning resources available at Juniper Networks1.

D is definitely wrong, the interface shuts down!

C is misleading, only learned devices before the violation can still communicate.

Wait, I thought it auto-cleared after a while?

A is correct, you have to clear it manually.

I remember that option D is definitely wrong; if a violation occurs, the interface shuts down, so it can't send or receive traffic.

I practiced a similar question, and I think option C is misleading because I believe once a violation happens, all traffic is stopped.

I'm not entirely sure, but I feel like option B might be correct since some features do have a timeout, but I can't recall the exact timing.

I think option A sounds right because I remember reading that manual intervention is usually needed to clear shutdown violations.

This is a good test of my knowledge of the MAC address limit feature. I'll carefully consider each option and think through the implications to determine the correct answer.

Okay, I've got this. The key is to remember that by default, the interface is shut down when a violation occurs, and you have to manually clear the violation to resume traffic. Option A is the correct answer.

Hmm, I'm a bit confused about the different options here. I'll need to carefully read through each one and think about the implications of the MAC address limit and shutdown action.

This seems like a pretty straightforward question about the MAC address limit feature. I'll need to remember the default behavior when a violation occurs.

I'm not totally sure about this one. I know the MAC address limit feature can be tricky, and I'll need to double-check my understanding of the default behavior when a violation happens.

Hmm, I'm a bit confused. I thought security groups were just for controlling inbound traffic, not outbound. I'll have to think this through carefully.

I'm a bit confused by this question. The options all sound kind of similar to me. I think I'll go with B since it's the only one that specifically mentions creating a list of discovered IPs.
