Which option describes the demand when available CPU resources are consumed by zones z1 and z2?

You administer a system with three nonglobal zones. All three-zones (z1, z2, and z3) use a
common resource pool. The pool is a fixed, two-CPU configuration. The default scheduler is FSS.
Zones z1 and z2 run applications that, over time, consume all available CPU resources. You have
allotted 20 shares each to these zones. Zone z3 runs a mission-critical application, so you allotted
it 60 shares. Because of application maintenance, zone z3 is currently using about 10% of the
CPU resources in the shared pool. Which option describes the demand when available CPU
resources are consumed by zones z1 and z2?

A.
Zones z1 and z2 will consume CPU resources until each zone consumes all the resources that
they require, up to 100%.

B.
Zones z1 and z2 will consume CPU resources until each zone consumes approximately 20%
of the CPU resources, and only then they will be constrained.

C.
Zones z1 and z2 will consume CPU resources until each zone consumes approximately 60%
of the CPU resources, and only then they will be constrained.

D.
Zones z1 and z2 will consume CPU resources until each zone consumes approximately 90%
of the CPU resources, and only then they will be constrained.
