Which types of entries exist in the MAC Address-Table?

The MAC Address-Table, also known as the Content Addressable Memory (CAM) table, is crucial for the operation of network switches. It records MAC addresses and their corresponding port numbers, enabling switches to make efficient forwarding decisions.

The correct response highlights two types of entries: static and dynamic. Static entries are those that are manually configured and will remain in the MAC Address-Table until they are explicitly removed by an administrator. This is useful for devices that need a fixed address association, such as servers or routers, aiding in enhanced network stability and security.

Dynamic entries, on the other hand, are learned automatically by the switch as it receives Ethernet frames. The switch observes the source MAC addresses of incoming frames, records the MAC along with the port on which the frame was received, and updates the table accordingly. These entries have a limited lifespan and will expire after a certain timeout period, ensuring that the table is kept up to date with the current devices on the network.

The other terms provided do not accurately describe the classification of MAC address table entries. For instance, temporary and permanent suggest a binary distinction that does not cover how MAC addresses are learned and aged out. Visible and invisible do not pertain to the standard definitions in networking contexts, nor do
