Oracle Oracle Certifications 1Z0-822 Questions & Answers

• Question 1:

  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

• 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

  Correct Answer: C

• Question 3:

  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%.

  Correct Answer: A

• Question 4:

  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.

  Correct Answer: A

• Question 5:

  Identify three ways in which the Fair Share Scheduler can be assigned.

  A. poolcfg

  B. dispadmin

  C. zonecfg set pool=

  D. zonecfg set cpu-shares=

  E. by creating a project and attaching a process to that project

  Correct Answer: BDE

• Question 6:

  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)

  Correct Answer: A

• Question 7:

  Which scheduling class cannot be assigned to a zone?

  A. RT

  B. FX

  C. TS

  D. SYS

  E. FSS

  Correct Answer: D

• Question 8:

  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.

  Correct Answer: E

• Question 9:

  Which command reports the scheduling class a process falls under?

  A. ps

  B. priocnt1

  C. dispadmin

  D. rctladm

  E. prstat

  Correct Answer: C

• Question 10:

  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

  Correct Answer: A
