Designing Cisco Data Center Infrastructure (DCID, legacy) — Question 68

Which innovation in the Cisco NX-OS Software brings an entirely new Layer 2 data plane by encapsulating the frames entering the device with a header that consists of a routable source and destination address?

Answer options

Correct answer: A

Explanation

The correct answer is A, OTV (Overlay Transport Virtualization), which allows Layer 2 frames to be encapsulated with routable addresses, enabling the transport of Ethernet frames over a Layer 3 network. Options B (MPLS), C (Routing), D (RSTP), and E (LISP) do not specifically provide this Layer 2 encapsulation with routable addressing as OTV does.
