Juniper JN0-351 Exam - Topic 3 Question 35 Discussion

Actual exam question for Juniper's JN0-351 exam
Question #: 35
Topic #: 3
[All JN0-351 Questions]

What is the default MAC age-out timer on an EX Series switch?

Show Suggested Answer Hide Answer
Suggested Answer: B, D

The two reasons for the failure to form an adjacency in a network running IS-IS could be:

B) There is no configured ISO address on any IS-IS interface.IS-IS requires each router interface to have an ISO address configured.Without this address, the routers cannot form an adjacency1.

D) The family iso configuration is missing from the adjacency interface.The 'family iso' configuration is essential for IS-IS to function correctly.If this configuration is missing from the adjacency interface, it could prevent the formation of an adjacency1.

These explanations are based on the Enterprise Routing and Switching Specialist (JNCIS-ENT) documents and learning resources available at Juniper Networks23.

Nope, it's not 30 seconds, that's way too short.

I’m leaning towards 300 seconds as well. I recall it being a common default setting in my studies.

I remember practicing a question about MAC address aging, and I feel like 30 minutes was mentioned, but that seems too long.

I've worked with EX Series switches before, and I believe the default MAC age-out timer is 300 seconds, or 5 minutes. I'm fairly confident in that, but I'll double-check my notes just to be sure.

Okay, let me see. 30 minutes or 300 seconds? That's a pretty big difference, so I'll have to weigh the options carefully here.

Hmm, this is a tricky one. I'm not sure if the default timer is in minutes or seconds. I'll have to think this through carefully.

I'm not too familiar with the default MAC age-out timer on EX Series switches, but I'll try to reason through this based on what I know about network switches in general.

If the timer was set to 30 minutes, I'd have enough time to take a nap in between network checks. Option C is just unrealistic.

300 minutes? That's way too long! I think the answer has to be option D - 300 seconds.
