To support the enterprise high-availability requirements, which workgroup switch technology can be used to interconnect multiple switches into a single logical unit?
The correct answer is A. StackWise. Cisco StackWise is a proprietary technology used on workgroup-class switches (e.g., Catalyst 3750, 3850, 9000 series) that physically interconnects multiple switches via a dedicated stacking cable, presenting them as a single logical switch with one management IP and a unified…

Explanation
Cisco StackWise is a proprietary technology used on workgroup-class switches (e.g., Catalyst 3750, 3850, 9000 series) that physically interconnects multiple switches via a dedicated stacking cable, presenting them as a single logical switch with one management IP and a unified control plane. VSS (Virtual Switching System) serves a similar purpose but targets distribution/core-layer switches like the Catalyst 6500/6800, not workgroup switches. EtherChannel bundles individual links for bandwidth and redundancy but does not merge switches into a single logical unit. vPC (Virtual Port Channel) is a Nexus data-center technology. Flex Links provides simple uplink redundancy as an STP alternative but does not create a logical unit of switches.
