Juniper Exam JN0-351 Topic 7 Question 16 Discussion

Actual exam question for Juniper's JN0-351 exam
Question #: 16
Topic #: 7
[All JN0-351 Questions]

You deployed a new EX Series switch with DHCP snooping enabled and you do not see any entries in the snooping databases for an interface. Which two Juniper configurations for that interface caused this issue? (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.

Whoa, Juniper really knows how to keep us on our toes with these DHCP snooping questions. Time to brush up on my trunk port and ARP inspection knowledge!

I'm confident it's C and D. Trunk ports and dynamic ARP inspection seem like the most likely culprits here.

Ha, I bet it's B and D. MAC limiting and dynamic ARP inspection - Juniper just loves to throw in those curveballs!

I'm going with A and C. A disabled port and a trunk port would both prevent DHCP snooping from working properly.

We should double check those configurations to make sure they are causing the problem.

Yeah, having a disabled port and a trunk port would definitely impact the DHCP snooping.

I don't think it's because of MAC limiting. I believe the interface being configured as a trunk port could also be causing the issue.

I agree with Antonio, that could be one of the reasons. Maybe MAC limiting is also enabled on the interface.

I think the issue might be because the interface is configured as a disabled port.
