Which two statements about stacking Cisco switches are true? (Choose two)
Click on the arrows to vote for the correct answer
A. B. C. D. E.DE
Stacking is a technique used to combine multiple physical switches into a single logical switch. The combined switches operate as one unit and are managed by a single IP address.
A. The administrator can create only one stack of switches in a network which is under the same administrative domain. This statement is false. An administrator can create multiple stacks of switches, each of which can be managed independently. Stacks can be created using different switch models and can be connected in different ways to form a larger network.
B. Each switch manages its own MAC address table. This statement is true. In a stacked configuration, each switch retains its own MAC address table. However, when a packet is forwarded between switches in the stack, the destination MAC address is compared against the MAC address tables of all switches in the stack, not just the one to which the packet is initially received.
C. When a new master switch is elected, it queries the previous master for its running configuration. This statement is true. In a stack of switches, one switch is designated as the master switch. The master switch is responsible for certain administrative tasks, such as configuration management and firmware upgrades. If the current master switch fails or is removed from the stack, a new master switch is elected. The new master switch queries the previous master switch for its running configuration, which allows for a seamless transition of administrative responsibilities.
D. The administrator can add additional switches to the stack as demand increases. This statement is true. Stacking allows for easy expansion of a network as demand increases. New switches can be added to the stack without having to reconfigure the network, and the new switches automatically inherit the configuration of the existing stack.
E. It enables the administrator to manage multiple switches from a single management interface. This statement is true. Stacking allows for centralized management of multiple switches from a single management interface. This reduces the administrative overhead associated with managing individual switches and provides a more efficient means of monitoring and configuring the network.
In conclusion, options B and D are the two statements about stacking Cisco switches that are true.
