   An admin has a 100GbE port that was previously broken out into four 25GbE ports. The admin now needs to revert it to a single 100GbE port to connect to a new storage array. The admin deletes the breakout configuration and saves the config, but the port still shows as four 25GbE interfaces. What is the most likely reason?

   • AThe switch was not reloaded after the breakout was removed.
   • BThe port profile is still applied to the parent port.
   • CThe port group membership is preventing the change.
   • DThe VLAN trunk configuration is blocking the revert.

   An admin is configuring ports for a set of cameras that all use the same untagged VLAN 100. The admin wants to apply the configuration efficiently and ensure that any future change to the camera VLAN only needs to be made once. What should the admin do?

   • ACreate a port profile for VLAN 100 and apply it to all camera ports.
   • BConfigure each camera port individually with the access VLAN 100 command.
   • CCreate a port group and assign all camera ports to it.
   • DUse a VLAN trunk with native VLAN 100 on each camera port.
