Explanation

Fabric C (option D) is the network fabric that connects directly to the chassis midplane. In chassis-based architectures, the midplane serves as the central backplane interconnect, and Fabric C is specifically designed and positioned to interface with it directly, enabling high-speed switching between line cards and system components.

Why the distractors are wrong:

• Fabric D (A) operates at a different layer of the fabric hierarchy and does not have a direct midplane interface.
• Fabric A (B) is typically associated with front-plane or external-facing connectivity, not the internal midplane.
• Fabric B (C) handles inter-fabric communication or redundancy roles, but does not connect directly to the midplane itself.

Memory tip: Think of C for Core - Fabric C sits at the core of the chassis, plugging directly into the central midplane. The letter C visually resembles a connector wrapping around the midplane structure, anchoring it in place.
