Discuss Nokia 4A0-115 Exam Topic 4 Question 19

Based upon the exhibit, which of the following statements is FALSE?

AVPLS 10 must be configured with two BGP instances on PE3 and PE4.

BOn PE3 and PE4, VPLS 10 must be configured with two different route-distinguisher values: one for VXLAN and another for MPLS.

COn PE3 and PE4, VPLS 10 must be configured with two different route-target values: one for VXLAN and another for MPLS.

DA BGP export policy is required on PE3 and PE4 to ensure that IMET routes originated with VXLAN encapsulation are not advertised to the peer across the core network.

Suggested Answer: C

PE2 advertises a MAC/IP route for MAC1 with a sequence number higher than that received from PE1. This indicates that MAC1 has moved from PE1 to PE2 and triggers a MAC withdrawal message from PE1 to remote PEs.CE1 does not generate an update message to PE1 withdrawing its MAC, nor does PE1 generate an update message to remote PEs identifying the new location of CE11.

D seems a bit confusing, why would we need that?

Ilona 11 months ago

C is definitely true, different route-targets are a must.

Willetta 11 months ago

Wait, are we sure about B? Sounds off.

Wei 11 months ago

Totally agree, that's standard practice!

Johna 12 months ago

A says two BGP instances are needed.

Sophia 12 months ago

The export policy on PE3 and PE4 sounds familiar, but I’m uncertain if it specifically prevents VXLAN routes from being advertised.

Dyan 1 year ago

I practiced a similar question where route-target values were discussed, but I’m confused if that applies here too.

Elizabeth 1 year ago

I think the route-distinguisher values are important, but I can't recall if they need to be different for VXLAN and MPLS.

Lera 1 year ago

I remember something about BGP instances, but I'm not sure if both PE3 and PE4 really need two instances for VPLS 10.

Marjory 1 year ago

This looks like a tricky one, but I think I can figure it out. I'll carefully analyze each option and use my knowledge of VPLS to determine which statement is false.

Lindsey 1 year ago

I'm a bit confused by the technical details in this question. I'll try to break it down and see if I can spot the incorrect statement.

Tran 1 year ago

Okay, I've got a strategy - I'll focus on the differences between VXLAN and MPLS configuration requirements for VPLS 10 on PE3 and PE4. That should help me identify the false statement.

Danica 1 year ago

This question seems straightforward, I'll carefully read through the options and eliminate the false statement.

Danilo 1 year ago

Hmm, the exhibit shows some VPLS configuration details, but I'm not entirely sure how to approach this. I'll need to think it through step-by-step.

Floyd 1 year ago

Okay, this looks straightforward. I'll start by creating the backup file with the tar command, then compress it with bzip2. After that, I'll check the SELinux status and make sure it's in enforcing mode.

Dyan 1 year ago

Okay, I've got a plan. I'll set the credentials as environment variables and use a key management system to keep them secure. That way, they're not in the code or the URL, and the platform will handle the storage for me.

This seems like a straightforward question about the risks of licensing products. I think the answer is B - the other companies becoming competitors.

Nickolas 1 year ago

Ugh, these types of questions really make me wish I had paid closer attention during the VPLS lectures.

Teri 1 year ago

Haha, I bet the exam writer was giggling when they came up with this one. Gotta love these trick questions!

C) Neighbors 10.10.10.2 and 10.10.10.3 have a service that uses a network identifier of 10.

B) Neighbors 10.10.10.2 and 10.10.10.3 have proxy-ARP enabled for the VPLS.

A) PEI populates this information into the local VPLS FDB.

Bobbye 1 year ago

C) seems false to me. The network identifier is 100, not 10.

Hector 2 years ago

I'm leaning towards B) since the exhibit shows the neighbors have proxy-ARP enabled. Tricky question!

Eura 1 year ago

↳ replying to Hector

Yes, I agree. The exhibit clearly indicates that neighbors 10.10.10.2 and 10.10.10.3 have proxy-ARP enabled for the VPLS.

Samuel 1 year ago

↳ replying to Hector

I think you're right, B) is the correct answer because of the proxy-ARP shown in the exhibit.

Gilma 2 years ago

I'm not sure, I think it might be C.

Felicia 2 years ago

D) is the correct answer. The exhibit shows that PEI uses LDP tunnels, not VXLAN, to reach the neighbors.

Izetta 2 years ago

I agree with Dana, D seems incorrect.

Dana 2 years ago

I think the false statement is D.
