問題文
A leaf was placed in the mode that isolates it from user traffic so that it could be debugged. The operator logs in to that switch and reads the state of the front panel ports and of the routing process. Both read as up. What holds?
選択肢
- The front ports are shut except for the ones facing the fabric, and the adjacencies of that process are kept up on purpose so that the switch can still be reached from the outside while it is being debugged.
- The front ports are up and only the ports facing the fabric are shut, and the readings are presented as they are because the isolation was applied to the fabric side of the switch alone.
- The front ports are shut and the adjacencies of that process are down, and the active readings are presented deliberately so that the debugging work can carry on while the switch is isolated.
- The front ports are up until the first frame arrives on them, and the readings are presented as they are because the isolation takes hold only once the switch has been put back into service.
