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

Static MAC address entries are manually configured by an administrator and, unlike dynamic entries, do not age out. These entries are part of the device's running configuration. If the administrator saves the running configuration to the startup configuration file (e.g., using the save command on Huawei devices), the static MAC address entries become persistent. Consequently, after the switch restarts, it loads the saved startup configuration, and the static MAC address entries are restored to the MAC address table.

This is a True/False question. The statement is True. If there were a 'False' option, it would be incorrect because saving the configuration makes static entries persistent across reboots.

- Huawei HedEx Documentation, S Series Switches, "MAC Address Table Configuration Guide", Section: Configuring a Static MAC Address Entry. The documentation states, "Static MAC address entries are manually configured... and do not age out. After the device restarts, static MAC address entries need to be reconfigured if the configuration is not saved." This confirms that if the configuration is saved, the entries persist.
