A network administrator wants to pre-configure new MSTP region settings on ArubaOS switches, and then apply the new settings at a later time. How can the administrator pre-configure the settings?
A. Change the MSTP region name after the new settings are configured.
B. Create a second spanning tree region on the switch and apply the settings to this region.
C. Use the pending option in the spanning-tree commands.
D. Change the MSTP region revision number after the new settings are configured.

I am not totally sure, however, reviewing HPE docs:
spanning-tree pending [ apply | | | reset ]
Manipulates the pending MSTP configuration. The command is useful in test or debug applications and enables rapid reconfiguration of the switch for changes in spanning tree operation.
apply –> Applies pending MSTP configuration (swaps active and pending configurations).
Sets the pending MST region configuration name. Default is the switch’s MAC address.
Sets the pending MST region configuration revision number. Default is 0.
Change pending MST instance configuration.
reset –> Copies the active configuration to pending.
Then, I think (not sure), it would be C.
