Juniper JN0-683 Exam - Topic 6 Question 21 Discussion

Actual exam question for Juniper's JN0-683 exam
Question #: 21
Topic #: 6
[All JN0-683 Questions]

Exhibit.

Connections between hosts connected to Leaf-1 and Leaf-2 are not working correctly.

Show Suggested Answer Hide Answer
Suggested Answer: C, E

Issue Analysis:

The problem in the exhibit suggests a mismatch in configuration parameters between Leaf-1 and Leaf-2, leading to communication issues between hosts connected to these leaf devices.

Configuration Mismatches:

Service-ID: Leaf-1 has service-id 1 configured, while Leaf-2 does not have this parameter. For consistency and proper operation, the service-id should be the same across both leaf devices.

VRF Target: Leaf-1 is configured with vrf-target target:65000:1, while Leaf-2 is configured with vrf-target target:65000:2. To allow proper VRF import/export between the two leafs, these should match.

Corrective Actions:

C . Configure the set switch-options vrf-target target:65000:1 parameter on Leaf-2: This aligns the VRF targets between the two leaf devices, ensuring they can correctly import and export routes.

E . Configure the set switch-options service-id 1 parameter on Leaf-2: This ensures that both Leaf-1 and Leaf-2 use the same service ID, which is necessary for consistency in the EVPN-VXLAN setup.

Data Center Reference:

Correct configuration of VRF targets and service IDs is critical in EVPN-VXLAN setups to ensure that routes and services are correctly shared and recognized between different devices in the network fabric.

Leaf-2's service-id might also need a look.

This question feels similar to one we practiced where we had to set the vrf-target. I think that might be relevant here too.

I remember something about configuring the vtep-source-interface, but I'm not entirely sure if it was for Leaf-1 or Leaf-2.

This seems straightforward enough. Based on the information provided, I believe the correct configuration changes are B and C. I'll double-check my work, but I'm feeling confident about this one.

I'm a bit confused by this question. The exhibit doesn't provide a lot of detail, and the configuration options seem quite specific. I'll need to think this through carefully to make sure I select the right changes.

Alright, I think I've got a plan. I'll start by looking at the exhibit and understanding the network topology. Then I'll review the configuration options and see which two would best address the connectivity issue between Leaf-1 and Leaf-2.

Okay, let's see here. The question is asking for two configuration changes, so I'll need to identify the two most relevant options from the choices provided.

Hold up, did someone say 'leaf'? I thought we were talking about trees, not networks! Anyways, I'd go with B and D. Just my two cents.
