Question #: 26
Topic #: 1
[All JN0-683 Questions]

You are using a single tenant data center with a bridged overlay architecture. In this scenario, how do hosts of the different virtual networks communicate with each other?

Show Suggested Answer Hide Answer
Suggested Answer: A

Understanding Bridged Overlay Architecture:

In a single-tenant data center using a bridged overlay architecture, virtual networks (VLANs) are typically isolated within the fabric, with traffic between these VLANs handled outside the fabric.

Communication Between Different Virtual Networks:

A . off-fabric using an external device: This is correct. In many bridged overlay architectures, communication between different virtual networks is handled off-fabric, often using an external router or firewall that connects the different VLANs. The fabric itself primarily provides Layer 2 connectivity within each VLAN, leaving inter-VLAN routing to be handled externally.

Data Center Reference:

This design is common in smaller or simpler data center environments where a single tenant does not require complex on-fabric routing and prefers to handle inter-VLAN routing through dedicated devices.

I agree with Malcolm, because anycast gateway addresses help in communication between different virtual networks.

I think the answer is B) using anycast gateway addresses configured on the leaf devices.

I'm just hoping the answer doesn't involve any 'off-fabric' shenanigans. That's a hard pass from me, dawg.

Hmm, D might be the hidden gem here. Those virtual gateway addresses on the spine could be a real game-changer. Worth a closer look, for sure.

C is the way to go, EVPN Type 5 routes are where it's at. Anything to avoid that external device nonsense, am I right?

Option B seems legit, using those anycast gateway addresses on the leafs. Keeps it all in-fabric, nice and tidy!
