Oracle Solaris 11 System Administrator — Question 6

The resource control in your zone is:
rctl:
name : zone.cpu-shares
value: (priv=privileged,limit=20,action=none)
When you boot the zone, this message is displayed:
WARNING: The zone.cpu-shares rctl is set but FSS is not the default scheduling class for this zone. FSS will be used for processes in the zone but to get the full benefit of FSS, it should be the default scheduling class.
Which option will resolve this issue?

Answer options

• A. In the global zone, run this command to change the process scheduler for the global zone: dispadmin -d FSS
• B. In the non-global zone, run this command to change the process scheduler for this specific zone: dispadmin -d FSS
• C. Change the zone resource control to: value: (priv=privileged,limit=20,action=none,default)
• D. Use svccfg to modify the general/scheduler property in the svc:/system/zones:default service: svccfg -s system/zones:default editprop general/scheduler=FSS

Correct answer: D

Explanation

Option D is correct because it directly modifies the scheduling property for the zone service to use FSS as the default scheduling class, which addresses the warning. Options A and B are incorrect because they only change the scheduler for either the global or non-global zone without addressing the default setting needed. Option C does not resolve the scheduling class issue but merely modifies the resource control value.
