After a switch restarts, static MAC address entries saved on the switch remain in the MAC address table.

The statement is true. Static MAC address entries are manually configured by an administrator and are stored as part of the device's configuration. When the save command is executed, the running configuration, including these static MAC entries, is written to the startup configuration file in non-volatile memory. Upon a system restart or power cycle, the switch loads this saved startup configuration, which repopulates the MAC address table with the previously configured static entries. This ensures they persist across reboots.

This is a true/false question where 'A' represents 'True'. The statement is factually correct; saved static MAC entries are persistent. A 'False' answer would be incorrect as it contradicts the fundamental behavior of saving configurations on network devices.
