Which two types of information are held in the mac address table? (Choose two.)
Click on the arrows to vote for the correct answerA. B. C. D. E.
The MAC address table, also known as the CAM table (Content Addressable Memory table), is a table that is used in network switches to maintain a mapping of MAC addresses to their corresponding switch ports. When a packet enters the switch, the switch looks up the destination MAC address in the MAC address table to determine which port to forward the packet to.
The two types of information that are held in the MAC address table are:
MAC addresses - The MAC address of each device that has communicated with the switch is stored in the MAC address table. This allows the switch to quickly look up the destination MAC address of incoming packets and forward them to the correct port.
Port numbers - The port number associated with each MAC address is also stored in the MAC address table. This information is used by the switch to determine which port to forward incoming packets to based on the destination MAC address.
Answers A, B, and C are incorrect because the MAC address table does not contain information about destination IP addresses, protocols, or port numbers other than the port number associated with each MAC address.
Answer E is partially incorrect because while the source IP address is used by the switch to learn the MAC address of the device sending the packet, it is not stored in the MAC address table.
