You configured the Fail Share Scheduler on a server, and you defined CPU shares for two nonglobal zones. You now need to apply shares to the global zone. The configuration needs to be persistent across a reboot operation. Which utility will you use?
A. prctl
B. priocntl
C. zonecfg
D. dispadmin
Correct Answer: D
Explanation/Reference:
Explanation:
* Set the default scheduler for the system to be the FSS.
# dispadmin -d FSS
* Scheduling Class on a System with Zones Installed
Non-global zones use the default scheduling class for the system. If the system is updated with a new default scheduling class setting, non-global zones obtain the new setting when booted or rebooted. The preferred way to use FSS in this case is to set FSS to be the system default scheduling class with the dispadmin command.

Answer is A : prctl is used to manage scheduling class of a zone
not B: moves a process to FSS without rebot , after reboot scheduling class is changed back to default value
not C: zonecfg is used to configure a non global zone
not D: dispadm is used to change the scheduling class not assign CPU shares
i think it should be A as the configuration is on the Global Zone.
prctl -n zone.cpu-shares -v 60 -r -i zone global
