QUESTION 46 – Exhibit —

 

user@router> show system switchover

 

Graceful switchover: On

 

Configuration databasE. Ready

 

Kernel databasE. Version incompatible

 

Peer statE. Steady State

 – Exhibit —

 

You have enabled graceful Routing Engine switchover (GRES). During verification, you switched mastership and all interfaces went down.

 

Referring to the output shown in the exhibit, why did the interfaces go down?

 

A.

The synchronization failed because the Junos OS version on the backup is incompatible with the version running on the master.

B.

The synchronization failed because the Junos OS version on the backup does not support GRES.

C.

The synchronization failed because the Routing Engine models are different between

 

 

 

 

the master and backup.

D.

The synchronization failed because the master Routing Engine cannot communicate with the backup Routing Engine.

 

Answer: A
