Nokia 4A0-106 Exam - Topic 6 Question 44 Discussion

Click the exhibit.A Carrier Supporting Carrier (CSC) VPRN is configured on an Nokia 7750 SR for a customer carrier offering VPRN services. Which of the following about this configuration is FALSE?
B) When the customer carrier uses the same autonomous system number in various sites, use the 'loop-detect off' CLI command to disable the loop detection functionality on CSC-CE and PE routers.
A) In the CSC VPRN, configure an eBGP session between CSC-PE and CSC-CE and use the 'advertise-label vpn-ipv4' CLI command to enable the advertisement of VPN-IPv4 routes.
C) On the CSC-PE routers, use the 'carrier-carrier-vpn' CLI command to configure the VPRN service as CSC.
D) Configure an iBGP session between PE1 and PE2 and use the 'family vpn-ipv4' CLI command to directly exchange end-customer routes learned from CE1 and CE2.

I thought loop detection was always on, why turn it off?

I feel confident about the iBGP session and the 'family vpn-ipv4' command, but I wonder if there's a specific scenario where that might not apply.

I think the loop detection command is something I practiced, but I can't recall if it's actually needed when the same AS number is used.

I remember studying the eBGP session setup, but I'm not entirely sure if the 'advertise-label vpn-ipv4' command is always necessary in this context.

I'm uncertain, but I think spinning servers like that could fit with either Denial of Service or Eclipse. I really need to clarify those terms!

Hmm, I'm a bit confused by this question. I know Azure Defender is a security service, but I'm not sure exactly which resources it can protect. I'll need to do some quick research on the capabilities of Azure Defender before answering.

Using the 'family vpn-ipv4' command to exchange end-customer routes directly between PEs is a nice touch. It simplifies the configuration, though I'd want to ensure it doesn't introduce any performance issues.

Hmm, the 'advertise-label vpn-ipv4' command makes sense for enabling VPN-IPv4 route advertisement. I wonder if there's any other way to handle the same scenario without that command.

The CSC VPRN configuration seems straightforward, but I'm curious about the loop detection functionality. Disabling it could be risky if the customer's sites have the same AS number.
