A network administrator issues the command 'show mac address-table' on a switch and sees an entry: '0011.2233.4455 Dynamic Gi0/4'. What does this entry indicate?

The entry is static and will never age out.

The switch will flood frames destined to 0011.2233.4455 out all ports except Gi0/4.

The switch will drop frames destined to 0011.2233.4455 because it is a dynamic entry.

The switch will forward frames destined to 0011.2233.4455 only out port Gi0/4.

A network administrator is troubleshooting a performance issue. The switch is flooding a large amount of unicast traffic to all ports. The administrator suspects that the MAC address table is not being populated correctly. Which action would most directly help identify the cause?

Reboot the switch to clear the MAC address table.

Increase the MAC aging timer to the maximum value.

Check the MAC address table for entries that are aging out too quickly.

Disable MAC learning on the switch to see if flooding stops.

A network administrator is troubleshooting slow performance on a LAN. The administrator suspects that the switch is flooding too many frames because the MAC address table is not complete. Which action would most directly help the switch build a more complete MAC address table?

Ensure all devices are actively sending traffic so the switch can learn their source MAC addresses.

Enable port security to limit the number of MAC addresses per port.

Increase the MAC aging timer so entries remain longer.

Manually configure static MAC entries for all devices.

What is the primary purpose of the MAC address table in a switch?

To enable the switch to forward frames only to the appropriate port based on the destination MAC address

To determine the best path to a destination network

To prevent unauthorized devices from accessing the network

To store the IP addresses of all devices in the network
