Juniper JN0-351 Exam - Topic 7 Question 21 Discussion

Actual exam question for Juniper's JN0-351 exam
Question #: 21
Topic #: 7
[All JN0-351 Questions]

Exhibit

Referring to the exhibit, which two configuration changes must you apply for packets to reach from R1 to R3 using IS-IS? (Choose two.)

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.

I disagree, I thought we needed both levels enabled.

I’m leaning towards disabling Level 2 on R1's interface, but I can't recall if that’s the best move for this scenario.

I'm confused about whether we should enable or disable Level 2 on R3. I feel like I need to double-check my notes on IS-IS configurations.

I remember a similar question where we had to disable Level 2 on one of the routers. Could that be the right choice here too?

I think enabling Level 1 on R1's ge-0/0/1 interface might be necessary, but I'm not entirely sure about the other option.

Alright, I've got a strategy here. I'll focus on the interfaces between the routers and make sure the IS-IS levels are set up properly to allow packets to flow from R1 to R3. Gotta nail this one!

Whoa, this is a tough one. I'm a bit confused about the IS-IS levels and how they need to be configured. Gonna have to re-read the question a few times.

Okay, let me see here. I think the key is to enable the correct IS-IS levels on the interfaces between R1 and R3. Time to put on my problem-solving hat!

Okay, I think I've got a handle on this. The key principles I would focus on are data security, business continuity, and responsive change management. Those seem to address the plant managers' concerns about the centralized system.

Okay, let me see. I think the key is understanding the different Hyper-V network types and what they're used for. I'm going to review my notes and try to eliminate the options that don't make sense.

This one seems pretty straightforward. I think the answer is D - email notification to be sent via SMTP from the LTM device.

I wonder if the packets could just take a shortcut and parachute their way from R1 to R3. That would be a lot easier than all this configuration stuff.

Wait, don't we need to disable Level 2 as well? I'm pretty sure that's the key to this puzzle.
