Which option describes the values you would expect to see for the CPU field for the zones?

You have a server that has two zones configured. These zones use the pool named pool_zones.
Examine the following configuration information:

The system has four CPUs. Assume that both zones are under heavy load. Examine the following
partial output:

Which option describes the values you would expect to see for the CPU field for the zones?

A.
approximately 40% for z1 and approximately 60% for z2

B.
approximately 60% for z1 and approximately 40% for z2

C.
approximately 20% for z1 and approximately 30% for z2

D.
approximately 30% for z1 and approximately 20% for z2

E.
approximately 25% for z1 and approximately 25% for z2

Explanation:
From the poolcfg –c info command output we see that FSS (Fair Share Scheduler)
is used.
From the prctl command output we see that zone z1 has been configured with a zone.cpu-shares
value of 40.
* The pool_default has a value of 100 CPU shares.
* prstat
– report active process statistics
Option –Z
-Z
Report information about processes and zones. In this mode, prstat displays separate reports
about processes and zones at the same time.

Why not C? In the server there are 4 CPUs, in pool we set 2 CPU (pset.min, pset.max). So zones can use 2 CPUs.

I agree on it being C, since the Pool is using 50% of the CPU , so percenteges would be base on the % of use of the Pool (40 & 60%) * % of the System Resources the Pool has…I’d go with Z…
