Juniper JN0-683 Exam - Topic 6 Question 30 Discussion

Actual exam question for Juniper's JN0-683 exam
Question #: 30
Topic #: 6
[All JN0-683 Questions]

Exhibit.

Referring to the configuration shown in the exhibit, assume that there is no external router present, and that the configuration is fabric-only.

Which two statements are true about the example configuration? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: B, D

Understanding the Configuration:

The exhibit shows configurations for two VRFs (Customer_A and Customer_B) with specific VLANs and VNIs assigned. Each VRF has interfaces (IRBs) associated with particular VLANs.

Communication Between VLANs and Routing Instances:

Option B: VLAN 400 (irb.400) is part of Customer_B, and there is no direct connection or routing between Customer_A and Customer_B in the configuration provided. Therefore, devices in irb.400 cannot communicate directly with devices in the Customer_A routing instance.

Option D: Since irb.400 (VLAN 400) and irb.800 (VLAN 800) are part of the same routing instance (Customer_B), they can communicate over the fabric using VXLAN encapsulation.

Conclusion:

Option B: Correct---There is no direct communication between devices in irb.400 (Customer_B) and routing instance Customer_A.

Option D: Correct---Devices in VLAN 400 and VLAN 800 can communicate within the Customer_B routing instance over the fabric.

I disagree, B) is misleading; they can communicate indirectly.

I believe devices in Customer A and Customer B can communicate, but I need to recall how the routing instances were set up in the examples we practiced.

I'm uncertain about the communication between irb.400 and irb.800; I thought they might be isolated, but I need to double-check that.

I remember a practice question where we discussed routing instances, and I feel like devices in different instances can't communicate directly.

I feel pretty confident about this one. The key is to focus on the relationships between the VLANs, routing instances, and the fabric configuration.

Okay, let's take this step-by-step. I'll start by looking at the VNI assignments and then consider the communication paths between the different network segments.

A) is definitely true, VNI 10006 is linked to vlan 800.

I think A and B are correct. VNI 10006 should link to vlan 800.

This is a good opportunity to apply my knowledge of Juniper networking concepts. I'll need to think through the implications of the fabric-only setup.

I think VNI 10006 is linked to vlan 800, but I'm not completely sure about the specifics of the irb configurations.

Hmm, I'm a bit confused by the fabric-only requirement. I'll need to make sure I understand how that affects the communication between the different VLANs and routing instances.

This looks like a tricky configuration question. I'll need to carefully analyze the exhibit and the statements to determine which ones are true.
