問題文
An administrator can move users onto replacement handsets either through the Self-Provisioning IVR or through the Phone Migration Service. What does each of the two prerequisite lists say about autoregistration?
選択肢
- The list for the IVR route has it turned on, and the list for the migration service route has it turned off, so the two routes ask for opposite settings of that one parameter, so a cluster can never be left ready for both at once.
- The list for the IVR route has it turned off, and the list for the migration service route has it turned on, which is why the migration service is the only one of the two that can be used on a cluster still running autoregistration.
- Both lists have it turned off, because leaving it on would let any handset plugged into the network take a directory number before the administrator has decided which user it belongs to.
- Both lists have it turned on, because a replacement handset has no configuration of its own yet and has to reach the cluster somehow before it can be matched to the user it is meant to serve.
