Explanation

Cisco's NCS 2000 optical platform is built on three core nLight pillars: nLight Silicon (B) provides the custom photonic integrated circuit ASICs that enable high-density, low-power optical signal processing; nLight Control Plane (C) delivers the software-defined, automated management and provisioning layer for the optical network; and nLight ROADM (D) implements the reconfigurable optical add-drop multiplexer technology that enables flexible wavelength routing.

The distractors - nLight Routing (A), nLight Switching (E), and nLight Convergence (F) - are fabricated terms that do not correspond to any defined component of Cisco's nLight architecture; they are designed to sound plausible but don't exist in Cisco's NCS 2000 documentation.

Memory tip: Think "SiCoR" - Silicon, Control Plane, ROADM - the three real layers of nLight: the hardware chip, the software brain, and the optical switching fabric. If an answer choice doesn't map to one of those three layers (physical, control, or optical), it's a distractor.
