Juniper JN0-351 Exam - Topic 5 Question 27 Discussion

Actual exam question for Juniper's JN0-351 exam
Question #: 27
Topic #: 5
[All JN0-351 Questions]

A new network requires multiple topology support. You decide to use IS-IS in this situation. Which three protocol topologies are supported in this scenario? (Choose three.)

Show Suggested Answer Hide Answer
Suggested Answer: A

Option A is correct.The storm control feature is enabled in the factory-default configuration on EX Series switches12.On EX2200, EX3200, EX3300, EX4200, and EX6200 switches, the factory default configuration enables storm control for broadcast and unknown unicast traffic on all switch interfaces2.On EX4300 switches, the factory default configuration enables storm control on all Layer 2 switch interfaces1.

Option B is incorrect.The storm control feature does not require a special license on EX Series switches34.

Option C is incorrect. There's no information available that suggests the storm control feature is not supported on aggregate Ethernet interfaces.

Option D is incorrect.The storm control configuration applies to traffic at the ingress of an interface5, not just between the forwarding and control plane.

I thought IS-IS was only for IPv4. This is interesting!

Yup, IPv4 and IPv6 are standard, but multicast is key too.

Wait, can IS-IS really handle anycast? That’s new to me.

I’m pretty confident that both IPv4 and IPv6 are supported by IS-IS. I think multicast is also a possibility, but I’m not 100% sure.

I’m a bit confused about anycast. I don’t recall if IS-IS supports it. I know it’s used in some routing protocols, but not sure about this one.

I feel like I saw a practice question about IS-IS and multicast support. I think multicast might be one of the answers here too.

I remember studying IS-IS, but I'm not entirely sure which topologies it supports. I think IPv4 is definitely one of them.

This is a tricky one. I know IS-IS supports some advanced routing features, but I'm not familiar with the specific topologies it supports. I'll have to guess on this one.

Okay, let's see. IS-IS supports IPv4 and IPv6 for sure. I think multicast might also be one of the supported topologies, but I'm not 100% certain.

Hmm, I'm not sure about this one. I'll have to think it through carefully and review the IS-IS protocol details.

I bet the exam writers were like, 'Let's see if they can IS-IS the difference between these options.'

Wait, does IS-IS even support IPsec? I thought that was more of an enterprise thing, not really a routing protocol thing. Whoever wrote this question needs to brush up on their networking fundamentals.

I'm just glad they didn't include OSPF in the options. That would have been a dead giveaway that they were testing our IS-IS knowledge. Gotta love these vendor-specific protocol questions.

Okay, let's think this through. IS-IS supports IPv4 and IPv6, so C and E are definitely correct. Multicast, that makes sense too. But anycast? Hmm, not so sure about that one.

Hold up, IPsec? Really? I thought we were talking about network topologies, not cryptographic protocols. This question is trying to trick us for sure.
