Nokia 4A0-D01 Exam - Topic 4 Question 5 Discussion

Actual exam question for Nokia's 4A0-D01 exam

Question #: 5
Topic #: 4

[All 4A0-D01 Questions]

Which of the following statements about IP-VRFs in Nokia's SR Linux is FALSE?

AAn IP-VRF is a Layer 3 network instance.

BPackets in an IP-VRF are forwarded based on the destination IP address.

CThe router maintains a distinct route table for each IP-VRF instance.

DMultiple servers can be connected to the same subnet in an IP-VRF.

Show Suggested Answer

Suggested Answer: D

Multiple servers connected to the same subnet typically reside within the same Layer 2 domain or MAC-VRF. IP-VRFs operate at Layer 3 and segment routing and forwarding by separate routing tables, so multiple servers on the same subnet are not a function of IP-VRF.

Wait, are we sure about C? Distinct route tables seem odd.

B is spot on, forwarding is based on destination IP.

I think D sounds off, can multiple servers really share a subnet?

IP-VRF is definitely a Layer 3 instance.

I feel like B is correct too, but I’m a bit confused about how forwarding works in VRFs.

I practiced a similar question where the distinct route table for each IP-VRF was emphasized, so C should be true.

I’m not sure about D; I think multiple servers can share a subnet, but does that apply to IP-VRFs?

I remember that IP-VRFs are definitely Layer 3 instances, so A seems true.

This is a tricky one. I know IP-VRFs are used for virtual routing and forwarding, but the details are a bit fuzzy. I think I'll eliminate the option that seems the most different from the other characteristics I'm familiar with.

Okay, let me see. I remember that IP-VRFs allow for segmentation and isolation of network traffic. So the statement about multiple servers being connected to the same subnet doesn't sound right to me. I'll go with that one.

Hmm, I'm a bit unsure about this. I know IP-VRFs have to do with routing and forwarding, but I'm not entirely clear on the specifics. I'll have to think this through carefully.

I'm pretty confident about this one. I know IP-VRFs are Layer 3 network instances, and the router maintains separate route tables for each instance. The key is to identify the statement that doesn't fit with those characteristics.

This question is making my head spin like a top! But I'm pretty confident the correct answer is A. An IP-VRF is definitely a Layer 3 network instance. Or is it a Layer 2? Ugh, I need a nap.

I agree with Jackie. Each IP-VRF has its own routing table, so multiple servers cannot be connected to the same subnet within an IP-VRF.

I'm going to have to go with B. Packets in an IP-VRF are forwarded based on the unicorn's horn, not the destination IP address. Everyone knows that!

Hmm, I think A is the false statement. An IP-VRF is a Layer 2 network instance, not Layer 3. Or is it the other way around? I'm getting my layers mixed up!
