Juniper JN0-664 Exam - Topic 4 Question 15 Discussion

Posted by Xochitl on Dec 12, 2023 at 09:03 AM

Exhibit

Which two statements about the configuration shown in the exhibit are correct? (Choose two.)

Suggested Answer: C

The resolve-vpn parameter is a BGP option that allows a router to resolve labeled VPN-IPv4 routes using unlabeled IPv4 routes received from another BGP peer with family inet labeled-unicast configured. This option enables interprovider VPNs without requiring MPLS labels between ASBRs or using VRF tables on ASBRs. In this scenario, you need to configure the resolve-vpn parameter under [edit protocols bgp group external family inet labeled-unicast] hierarchy level on both ASBRs.

I thought Layer 2 was more common for this setup?

Totally agree, same AS number is not the case here.

Wait, are we sure it's a Layer 2 VPN? Seems off.

I think it connects sites with different AS numbers.

A Layer 3 VPN is definitely configured here.
AS

I feel like I saw something about Layer 3 VPNs in my notes, so I might go with D, but I need to double-check the details on AS numbers.
ED

I'm leaning towards B and D, but I can't recall if the exhibit clearly shows whether it's Layer 2 or Layer 3. It's a bit confusing!
RY

I remember practicing a question similar to this, and I think Layer 2 VPNs are typically used for connecting different AS numbers, so maybe C is right.
TA

I think option A might be correct since different AS numbers usually indicate different customer sites, but I'm not entirely sure.

This is a tricky one. The exhibit doesn't give a lot of detail, and the answer choices seem pretty similar. I'll need to really think through the differences between Layer 2 and Layer 3 VPNs, and how AS numbers might factor in. Gotta be careful with this one.

Okay, the exhibit shows a VPN connection between two customer sites. I think the key is figuring out whether it's a Layer 2 or Layer 3 VPN, and whether the sites use the same or different AS numbers. I'll go through the options systematically.

Hmm, the exhibit shows some kind of VPN setup, but I'm not entirely sure what type it is. I'll need to read the answer choices closely and see if I can identify the key details about the configuration.

This looks like a pretty straightforward VPN configuration question. I'll carefully review the exhibit and the answer choices to determine which two statements are correct.

I'm a bit unsure about the difference between calculated fields and other types of fields. I'll need to review that concept before answering.
LU

Hmm, I'm not sure if Calculation is the right choice here. I think I'd go with a Formula to calculate the age and then an Alert to show the error message if needed.

I'm a little confused on the hierarchy here. I know the Code and regulations are key, but I'm not sure if court decisions or IRS agent reports might carry more weight for specific tax planning situations. I'll have to review my notes to be sure.

Easy peasy, it's D. terraform apply. That's the one that takes the Terraform configuration and creates the actual resources in your cloud environment.

I'm pretty sure the correct answer is 'Yes, please' and 'Sign me up for another certification exam!'

Wait, what's an 'AS number' again? Is that like a phone extension or something? I'll just guess C and D to be safe.
HE
Hector 2 years ago
I'm not sure about option B, but I think option D is incorrect because it looks like a Layer 2 VPN is configured.
VE

I agree with Leonor, option A seems to be the right choice based on the configuration.
MY

I'm a little confused by the use of 'AS numbers' here. Isn't that more of a BGP thing? Anyway, I'll hedge my bets and say A and D.

Hmm, this looks like a trick question. I'm going to go with option B and D - a Layer 3 VPN that connects customer sites with the same AS number.
LE

I think option A is correct because the exhibit shows different AS numbers.
