Oracle Solaris 11 Advanced System Administration Exam
Question 1
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 approximately 20% of the CPU resources, and only then they will be constrained.
- B. 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.
- C. 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.
- D. Zones z1 and z2 will consume CPU resources until each zone consumes all the resources that they require, up to 100%.
Answer:
A
Question 2
Which utility/service must you use to set processes with FSS by default?
- A. priocntl
- B. svc:/system/scheduler:default
- C. dispadmin
- D. projmod
Answer:
C
Question 3
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
Answer:
D
Question 4
Which scheduling class distributes CPU resources among its processes based on assigned
importance?
- A. Fair Share Scheduler (FSS)
- B. Real-Time (RT)
- C. Fixed-priority (FX)
- D. Timesharing (TS)
Answer:
A
Question 5
Identify three ways in which the Fair Share Scheduler can be assigned.
- A. poolcfg
- B. dispadmin
- C. zonecfg set pool=<value>
- D. zonecfg set cpu-shares=<value>
- E. by creating a project and attaching a process to that project
Answer:
B, D, E
Question 6
Consider the following command:
dispadmin -c IA -g -r 1000000
Which statement correctly describes the result?
- A. The quantum will be reported in milliseconds.
- B. The quantum will be output every 1000000 milliseconds.
- C. The quantum will be reported in microseconds.
- D. The quantum will be output every 1000000 microseconds.
Answer:
A
Question 7
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
Answer:
A
Question 8
Which command reports the scheduling class a process falls under?
- A. ps
- B. priocnt1
- C. dispadmin
- D. rctladm
- E. prstat
Answer:
C
Question 9
Can you change the scheduling class of a zone's processes to FSS without rebooting?
- A. No. Set the zone's scheduling-class attribute to FSS and reboot.
- B. No. Run dispadmin –d FSS inside the zone, then reboot.
- C. No. Run dispadmin –d FSS in the global zone, then reboot the nonglobal zone.
- D. Yes. Run dispadmin –d FSS inside the zone.
- E. Yes. Run priocntl –s –c FSS –i all inside the zone.
Answer:
E
Question 10
Which scheduling class cannot be assigned to a zone?
- A. RT
- B. FX
- C. TS
- D. SYS
- E. FSS
Answer:
D
