JNCIP-DC: Juniper Networks Certified Professional – Data Center (2023) — Question 32

You are implementing a second data center and must have some of your VLANs active in both data centers. You must provide high availability, fast reconvergence, and avoid tromboning traffic on these VLANs.
In an over-the-top DCI strategy, which two statements are correct? (Choose two.)

Answer options

• A. A single type-5 route for the subnet must be advertised from both data centers.
• B. The VLAN ID and VNI must be the same in both data centers for these VLANs.
• C. The VLAN ID must be the same in both data centers, but the VNI can be different.
• D. A type-5 route for each host must be advertised from the data center where the host resides.

Correct answer: B, C

Explanation

The correct answers are B and C because having the same VLAN ID and VNI ensures proper communication and segmentation across both data centers. Option A is incorrect as it oversimplifies the routing requirements, and option D is not applicable in this context as it relates to host-specific routing, which does not address the VLAN requirements for high availability.
