Actual exam question for Juniper's JN0-363 exam

Question #: 38
Topic #: 2

[All JN0-363 Questions]

Exhibit

Which two statements are correct about the service provider MPLS network shown in the exhibit? (Choose two.)

AR3 is considered a P router.

BR3 is considered a PE router.

CR3 is considered a transit router.

DR3 is considered an ingress router.

Show Suggested Answer

Suggested Answer: D

The BGP (Border Gateway Protocol) refresh message is used to request the re-advertisement of the IPv4 unicast or multicast routing information that was previously sent by the sender to the receiver and acknowledged using TCP. This message helps in refreshing the routes in case of route table changes or to ensure that the receiver has the latest and most accurate routing information.

I thought ingress routers were different from this setup.

Wait, are we sure about R3 being a P router?

I feel like I’ve seen a similar question before, but I can't remember if ingress routers are always PE routers. This is tricky!

If R3 is a transit router, then it shouldn't be directly connected to customer networks, right? That makes me lean towards option A.

I remember something about P and PE routers, but I can't recall the exact definitions. Did we cover transit routers in class?

I think R3 might be a PE router since it connects to customer networks, but I'm not entirely sure.

This is a straightforward MPLS question, in my opinion. I just need to carefully read the answer choices and select the two that best describe the role of R3 in the network.

I'm a bit confused by the terminology used in the answer choices. I'll need to review my MPLS concepts to make sure I understand the differences between P, PE, transit, and ingress routers.

Okay, let me think this through step-by-step. The question is asking about the role of router R3 in the MPLS network, so I need to understand the different types of MPLS routers and how they function.

Hmm, this looks like a tricky MPLS question. I'll need to carefully analyze the network diagram and the answer choices to determine which two statements are correct.

I've got a good handle on MPLS, so I think I can tackle this question. I'll start by identifying the key characteristics of each router type and then match them to the information provided in the exhibit.

Okay, I think I've got it. The importance weight of 11 means this KPI is weighted heavily, so it could have a significant impact on the overall health score.

I'm a little confused by the terminology here. What exactly is the difference between V2I, V2V, V2P, and V2N? I want to make sure I understand the concepts before selecting an answer.

I bet the network admin in charge of this MPLS setup is feeling pretty 'PE-roud' of their work.

Hmm, I was tempted to choose A, but then I remembered that P routers are the core MPLS routers, not the edge ones. B and D it is!

I almost chose A too, but you're right, P routers are in the core of the network.

D is correct because ingress routers are responsible for receiving packets from CE routers.

This is a tricky one. I'm going to go with B and C since R3 seems to be a transit router as well as a PE router.
