Which characteristic describes Cisco StackWise technology?

Cisco StackWise technology uses proprietary StackWise cables to connect switches in a stack, forming a single logical switch. This cabling is unique to Cisco and is essential for the high-speed, dedicated stacking interconnect. Incorrect options: StackWise is primarily supported on Cisco Catalyst 2960-X, 3750, 3850, and 9300 series switches, not the 4500 series, which typically uses VSS (Virtual Switching System) for high availability. StackWise requires physical proximity between switches, typically within the same rack or closet, and does not support geographically separated devices. StackWise can combine more than two devices, with the exact number depending on the switch model (e.g., up to 9 switches for Catalyst 3750/3850, up to 8 for Catalyst 9300).
