Discuss Juniper JN0-664 Exam Topic 4 Question 28

Exhibit

You want Site 1 to access three VLANs that are located in Site 2 and Site 3 The customer-facing interface on the PE-1 router is configured for Ethernet-VLAN encapsulation.

What is the minimum number of L2VPN routing instances to be configured to accomplish this task?

Suggested Answer: D

BGP policy framework is a set of tools that allows you to control the flow of routing information and apply routing policies based on various criteria. BGP policy framework consists of several components, such as route maps, prefix lists, community lists, AS path lists, and route filters. Route maps are used to define routing policies by matching certain conditions and applying certain actions. Prefix lists are used to filter routes based on their prefixes. Community lists are used to filter routes based on their community attributes. AS path lists are used to filter routes based on their AS path attributes.Route filters are used to filter routes based on their prefix length or range3. In this question, we have a route map named ISP-A that has two clauses: clause 10 and clause 20. Clause 10 matches any route with a prefix length between 8 and 24 bits and sets the local preference to 200. Clause 20 matches any route with a prefix of 224.7.7.7/32 and rejects it. The route map is applied inbound on the BGP neighborship with ISP-A. Based on this configuration, the correct statement is that joins for group 224.7.7.7 are always rejected, regardless of the group count. This is because clause 20 explicitly denies any route with a prefix of 224.7.7.7/32, which corresponds to the multicast group 224.7.7.7.

I agree with Cherry, 3 is the right call here!

Bernardo 11 months ago

Wait, are we sure about that? Seems like it could be more complicated.

Naomi 11 months ago

Definitely 1 instance if they’re all in the same service.

Laurene 11 months ago

I think it's actually 2 instances, not 3.

Cherry 12 months ago

You need at least 3 L2VPN instances for 3 VLANs.

Rosalyn 12 months ago

I’m leaning towards 1 instance since it’s Ethernet-VLAN encapsulation, but I’m not confident about that.

Tarra 1 year ago

I feel like we could manage with just 2 instances, but I can't recall the exact details from the study materials.

Alisha 1 year ago

I remember a practice question that mentioned needing multiple instances for different VLANs, so maybe it's 3?

Whitney 1 year ago

I think we might need one L2VPN instance for each VLAN, but I'm not entirely sure if that's the case.

Jettie 1 year ago

I'm pretty confident I can solve this. The key is understanding how the Ethernet-VLAN encapsulation on the PE-1 router affects the L2VPN configuration. I'll need to consider the number of VLANs and sites involved to determine the minimum number of routing instances.

Denise 1 year ago

Okay, let me break this down step-by-step. Site 1 needs access to 3 VLANs in Site 2 and Site 3. The PE-1 router is using Ethernet-VLAN encapsulation, so I think I need to set up L2VPN routing instances to connect the sites.

Rory 1 year ago

I'm a bit confused by the Ethernet-VLAN encapsulation requirement. Does that mean I need to consider some kind of Layer 2 VPN solution? I'll have to review my notes on that.

Nickolas 1 year ago

This seems like a straightforward VLAN connectivity question. I'll need to think through the minimum number of L2VPN routing instances required to connect the VLANs across the sites.

Shantell 1 year ago

I've got this! Output networks are more expensive but more reliable, so the statement is true. Easy peasy.

Natalya 1 year ago

Ugh, audit criteria questions are always tricky. I'll need to draw on my knowledge of auditing principles to figure out which option is the odd one out here.

Tess 1 year ago

Hmm, this seems like a tricky one. I'll need to think carefully about the differences between proportion measures and the options given.

Apolonia 1 year ago

I'm a bit confused on this one. I know GDPR has strict rules around sensitive personal data, but I'm not sure if financial information falls into that category. I'll have to make an educated guess and go with option B.

Simona 1 year ago

Okay, let's see... Three VLANs, two sites, and a PE router. Sounds like a recipe for a networking nightmare. Wait, is the answer 6? Because why not, am I right?

Candida: That makes sense. So, the minimum number of L2VPN routing instances needed is 3.

User 2: I believe the answer is 3, considering the number of VLANs and sites involved.

User 1: No, the answer is not 6. Think about it again.

Leeann 1 year ago

Ah, the joys of Layer 2 VPNs. It's like a maze of tunnels, but with more acronyms than a tech conference. The answer's gotta be 3, just to keep things interesting.

Galen 1 year ago

Hmm, let me think... If I had a nickel for every time I had to configure multiple routing instances, I'd be rich enough to buy my own island. But I digress, the answer is 2, right?

Absolutely! The answer is 2 routing instances.

Rodrigo 1 year ago

I think it's 1.

Boris 1 year ago

↳ replying to Galen

That's right! It is indeed 2 routing instances that need to be configured.

Dick 1 year ago

↳ replying to Galen

No, the correct answer is 3.

Loise 1 year ago

Yes, you are correct! The minimum number of L2VPN routing instances to be configured is 2.

Yes, the answer is 2.

One routing instance? That's like trying to herd cats with a single leash. This question is as confusing as a politician's tax plan.

Felicia 2 years ago

But if we need to access three VLANs, wouldn't we need three L2VPN routing instances?

Corrie 2 years ago

I disagree, I believe the answer is C) 2.

I think the answer is B) 3.
