At which hierarchy would you configure a static MAC address for interface ge-0/0/0?

Configuring a static MAC address is done at the specific interface level, as it directly pertains to that interface's operation and configuration. Therefore, the correct hierarchy to configure a static MAC address for the interface ge-0/0/0 is found within its dedicated configuration structure. This allows you to apply interface-specific settings, such as a static MAC address, directly related to the ge-0/0/0 interface.

The other options pertain to broader configurations where MAC address settings would not be appropriate:

• Configuring at the general interface level does not allow for specificity to an individual interface, as it would affect all interfaces under that hierarchy.

• VLAN settings are concerned with grouping interfaces but do not directly configure MAC addresses for individual interfaces.

• Protocol settings are related to the operational protocols on the device and do not handle MAC address configurations either at the interface or VLAN level.

Thus, focusing on the specific interface ge-0/0/0 is essential for correctly managing its MAC address assignment.
