Cisco 350-601 Exam - Topic 9 Question 65 Discussion

Actual exam question for Cisco's 350-601 exam

Question #: 65
Topic #: 9

Refer to the exhibit.

A VXLAN data center fabric consists of three hosts mapped to different VLANs. Ingress VTEPs perform Layer 2 bridging and Layer 3 routing. Egress VTEPs only perform a Layer 2 bridging lookup. Which VNI values must be set to allow inter-VNI communication?

AVLAN 100 to Layer 2 VNI 2020 -
Test_Telco_VRF to Layer 3 VNI 5050

BVLAN 100 to Layer 2 VNI 2020 -
VLAN 200 to Layer 2 VNI 5050

CVLAN 100 to Layer 2 VNI 2020 -
Test_Telco_VRF to Layer 3 VNI 1010

DVLAN 100 to Layer 2 VNI 1010 -
VLAN 200 to Layer 2 VNI 1010

Show Suggested Answer

Suggested Answer: C

In a VXLAN data center fabric, inter-VNI communication requires mapping Layer 2 (L2) VLANs to their respective L2 VNIs and associating them with the correct Layer 3 (L3) VNI that corresponds to the VRF.In this case, VLAN 100 is mapped to L2 VNI 2020, and for inter-VNI routing to occur, it must be associated with an L3 VNI that corresponds to the VRF, which is Test_Telco_VRF to L3 VNI 1010.Reference: For more detailed information, you can refer to the Cisco Programmable Fabric with VXLAN BGP EVPN Configuration Guide1and the Data Center VXLAN EVPN guide

Surprised there's no mention of multicast in this setup.

Totally agree with option B, it covers both VLANs well!

Wait, why would you use VNI 1010 for Layer 3? Seems off.

VNI 2020 is for VLAN 100, right?

I’m leaning towards option B because it mentions both VLANs and seems to cover the Layer 2 aspect well, but I’m not entirely confident.

I feel like VLAN 100 should definitely map to a Layer 2 VNI, but I'm confused about the Layer 3 VNI part. Does it have to be the same for both VLANs?

I think I practiced a similar question where VLANs were mapped to VNIs, but I can't recall the exact values. Was it 2020 or 5050?

I remember something about VNIs needing to be unique for inter-VNI communication, but I'm not sure which option fits that best.

I'm not entirely sure about this one. The VXLAN configuration seems complex, and I want to make sure I understand it correctly before selecting an answer. I'll review the question and exhibit again carefully.

Okay, I think I've got this. The key is that the ingress VTEPs need to have the same VNI values for Layer 2 and Layer 3 communication, while the egress VTEPs only need Layer 2 VNI values. I'll select the answer that matches that.

Hmm, I'm a bit confused by the different VLAN and VNI combinations in the answer choices. I'll need to think through the Layer 2 bridging and Layer 3 routing requirements to figure out the right solution.

This looks like a VXLAN configuration question. I'll need to carefully review the information provided in the exhibit and the answer choices to determine the correct VNI values for inter-VNI communication.

Hmm, the A1 attribute for the E1 element is marked as #IMPLIED, but the question mentions it's not set. I'll need to double-check the requirements for that.

Hmm, I'm not totally sure about this one. The details about the algorithm not being integer-based and using shorter keys have me a bit confused. I'll have to think this through carefully.

I think option B is the way to go. Alerting the manager that the proposal has been sent via email is a quick way to get the information to them quickly.

I think D) VLAN 100 to Layer 2 VNI 1010 - VLAN 200 to Layer 2 VNI 1010 makes more sense for inter-VNI communication.

That makes sense. But wait, what about the Test_Telco_VRF? Shouldn't that require a Layer 3 VNI?

I'm leaning towards option C. The question specifically says the ingress VTEPs perform both Layer 2 and Layer 3, so we'd need a Layer 3 VNI in addition to the Layer 2 VNIs. The 'Test_Telco_VRF' VNI of 1010 seems like the right choice for the inter-VNI communication.

Hmm, I'm debating between options B and C. Option B seems to map the VLANs directly to the Layer 2 VNIs, which makes sense. But option C mentions a 'Test_Telco_VRF' which could be the Layer 3 component.

I think it's asking about the VNI values needed to allow inter-VNI communication in this VXLAN data center fabric. The exhibit shows three hosts mapped to different VLANs, with ingress VTEPs handling both Layer 2 and Layer 3, and egress VTEPs only doing Layer 2 bridging lookup.

Ah, I see what you mean. Okay, let me think this through. If the egress VTEPs only do Layer 2 bridging, then we need to use Layer 2 VNIs for inter-VNI communication, right?

This question looks pretty straightforward, but I'm not too confident about it. The key seems to be understanding how VXLANs work with Layer 2 and Layer 3 communication.
