An administrator is trying to remove configurations from a switch. After using the command erase startup-config and reloading the switch, the administrator finds that VLANs 10 and 100 still exist on the switch. Why were these VLANs not removed?
- These VLANs cannot be deleted unless the switch is in VTP client mode.
- These VLANs can only be removed from the switch by using the no vlan 10 and no vlan 100 commands.
- These VLANs are default VLANs that cannot be removed.
- Because these VLANs are stored in a file that is called vlan.dat that is located in flash memory, this file must be manually deleted.
Answers Explanation & Hints: Standard range VLANs (1-1005) are stored in a file that is called vlan.dat that is located in flash memory. Erasing the startup configuration and reloading a switch does not automatically remove these VLANs. The vlan.dat file must be manually deleted from flash memory and then the switch must be reloaded.
