Switch stacking is a technology used in networking to combine multiple switches into a single logical unit to increase capacity, availability, and manageability. Here are the explanations for the two true statements about switch stacking:
A. The stack is powered by a single power cable:
When switches are stacked, they are treated as a single entity, and their power source is also consolidated. This means that the entire stack can be powered by a single power cable connected to one of the switches, simplifying power management. The power-sharing feature in switch stacking is also beneficial in terms of redundancy, as a backup power supply can be connected to one of the switches in the stack to provide uninterrupted power in case of a power outage.
C. The first and last switch in the stack must be connected to one another:
In a switch stack, the first and last switch must be physically connected to each other through a stacking cable. This forms the backbone of the stack and enables the switches to communicate and operate as a single unit. The stacking cable is typically a special cable that provides a high-speed and low-latency connection between the switches.
To summarize, switch stacking is a useful technology that allows network administrators to combine multiple switches into a single logical unit for easier management and increased capacity. Stacking cables are used to connect the switches physically, and the entire stack can be powered by a single power cable.
