Which technology allows the NCS 4000 to switch OTN and packet traffic simultaneously?

The correct answer is B. agnostic fabric. Agnostic fabric is correct because the Cisco NCS 4000 uses a transport-agnostic switching fabric - meaning the fabric is indifferent to traffic type and can simultaneously forward both OTN (Optical Transport Network) and packet/MPLS traffic across the same infrastructure…

Explanation

Agnostic fabric is correct because the Cisco NCS 4000 uses a transport-agnostic switching fabric - meaning the fabric is indifferent to traffic type and can simultaneously forward both OTN (Optical Transport Network) and packet/MPLS traffic across the same infrastructure, enabling true convergence on a single platform.

Why the distractors are wrong:

  • A. Hypervisor - a hypervisor virtualizes compute resources to run multiple operating systems; it has no role in OTN/packet switching.
  • C. Multichassis - refers to linking multiple chassis for scale or redundancy, not to the mechanism that enables dual-traffic-type forwarding.
  • D. CPAK - a Cisco optical transceiver form factor used for physical connectivity; it is a pluggable module, not a switching architecture.

Memory tip: Think "agnostic" = "doesn't discriminate." The agnostic fabric doesn't discriminate between OTN and packet traffic - it switches both without caring which type it is.
