Question 1
Single choice

A batch job runs daily in the QBATCH subsystem with a run priority of 50. The job normally takes an hour to complete and no other batch jobs run during this time.

The administrator needs to reduce the run time and requests the run priority be lowered to 40. However1 after the change, run time does not decrease.

What is the likely reason that the run time did not decrease?

A.

The run priority applies to only interactive jobs.

B.

D82 Symmetric Multiprocessing has not been installed.

C.

The run priority represents only the relative importance of the job.

D.

The system value QPFRADJ (Performance Adjustment) is set to "No adjustment."

Question 2
Single choice

Which graphical tool will help identity additional details about activity on the system, to isolate the root cause of performance problems?

A.

PEX

B.

iDoctor

C.

Performance Monitor

D.

Communications Trace

Question 3
Single choice

The threshold limit has been reached for the system ASP on a system running IBM i 7.1 . There are some disk units configured to a user ASP available. Business continuing policy prevents the administrator from stopping the system.

How could the system administrator correct the storage problem in the system ASP?

A.

Increase the ASP threshold above the currently utilized storage.

B.

Concurrently remove available disk units from user ASP using the "Remove units from configuration" SST option and add them to system ASP.

C.

Switch to the backup system using an HA solution and restart the original system to DST. Remove the available disk units from user ASP and add them to system ASP.

D.

Initiate a control panel function 21 to activate DST on the system console for the affected partition.
Use the DST feature to compress the parity stripe to increase available storage.

Question 4
Single choice

An administrator needs to restore a physical file DATALIB/SMALLFILE from a Save 21 backup of library DATALIB. DATALIB has several hundred large database files plus other objects.

The administrator has the job log and output from the last full save of DATALIB.

What should the administrator do to restore SMALLFILE in the shortest time?

A.

Run the RST command for object "/QSYS.LIB/DATALIB.LIB/SMALLFILE.FILE"

B.

Delete SMALLFILE, run RSTLIB specifying *NEW objects, and specify library DATALIB as the starting library.

C.

Run RSTLIB for library DATALIB specifying the position parameter for SMALLFILE in library DATALIB from the output of the save.

D.

Run RSTOBJ for DATALIB/SMALLFILE specifying the position and sequence number for SMALLFILE

in library DATALIB from the output of the save.

Question 5
Single choice

What are the key benefits provided by database journaling?

A.

Can send updates concurrently to a second system Can back out incomplete transactionsCan reduce
system I/O workload

B.

Can reduce application complexityCan back out incomplete transactionsCan maintain database integrity in the case of an unexpected outage

C.

Can send updates concurrently to a second system Can increase performanceCan maintain database integrity in the case of an unexpected outage

D.

Can send updates concurrently to a second system Can back out incomplete transactions and commitment controlCan maintain database integrity in the case of an unexpected outage

Question 6
Single choice

Journaling of a large library is running on SYSTEMA and the journal is system managed. Remote journaling to

SYSTEMB has been configured. Due to a communications problem between SYSTEMA and SYSTEMB, remote journaling is not working and cannot be quickly restarted.

Disk utilization on SYSTEMA is increasing rapidly. To reduce disk utilization the administrator tries to delete journal receivers on SYSTEMA. Attempts fail and the following message displays:

CPF705F: Receiver not replicated to 1 remote journals.

What must the administrator do to delete journal receivers on SYSTEMA?

A.

Delete and recreate only the journal, and then delete the receivers.

B.

Stop journaling, as this must be ended first, and then delete the receivers.

C.

Use the DLTJRNRCV command and change the delete option parameter to ignore target receivers.

D.

Use the CHGJRN command to change the Manage Receivers parameter to allow user management of

journal receivers and then delete the receivers.

Question 7
Single choice

Due to an application problem, management has requested the IPL of a partition running IBM i 7.1. The administrator initiates the IPL, and during the restart phase notices the IPL is running in manual mode even though the HMC partition settings indicate B NORMAL.

Why is the IPL running in manual mode?

A.

The PWRDWNSYS command restart parameter is set to *MANUAL.

B.

Manual is the default IPL mode when there is a console problem.

C.

The QIPLTYPE system value is set to "Attended IPL, Console in debug mode".

D.

Manual is the default IPL mode when the previous system end indicator is abnormal.

Question 8
Single choice

An administrator has been asked to update an IBM i 7.1 system to the most current Technology Refresh available from IBM.

Which method is the most appropriate to achieve the update?

A.

Perform a D-mode IPL using the Technology Group PTF package SF99707.

B.

Perform a slip install using the most current 1_Base_01 resave media available.

C.

Perform a scratch install using the most current 1_Base_01 resave media available.

D.

Perform an install of the Technology Group PTF package SF99707 using the GO PTF menu.

Question 9
Single choice

A company has just purchased a new POWER7 server running IBM i 7.1 to replace an older system running V5R4M5. Due to a mistake by a programmer on the V5R4 system, data was accidently deleted. To recover, the administrator backs up the deleted data to virtual tape on the 7.1 server and attempts to restore it on the V5R4 server. The restore on the V5R4 server fails with a message stating the data was saved from a more recent release of the operating system.

Which option will solve this problem?

A.

Save the data to physical media.

B.

Set the target release parameter to V5R4M0 when saving the data.

C.

ETP the virtual tape image catalog from the 7.1 server using binary mode.

D.

Use the target release parameter *RECOVER and the access path parameter set to VSR4MO.

Question 10
Single choice

A disaster recovery test is being performed, using backups from a production system. The backup process is as follows:

Full system save, using GO SAVE Option 21, for weekly backup SAVCHGOBJ LIB(*ALL) is used for daily library backup, in addition to DLO and IFS saves The disaster recovery test is at the point where libraries are ready to be restored

Which pair of actions will restore the libraries to the most recent save point, in the minimum amount of time?

A.

Use RSTLIB(*NONSYS) to restore all libraries and object from the SAVE 21 weekly save. For each daily tape, run a RSTLIB for each library saved by SAVCHGOBJ.

B.

Use RSTLIB(*NONSYS) to restore all libraries and object from the SAVE 21 weekly save. Then run a RSTOBJ for each library saved by SAVCHGOBJ on the most recent daily tape.

C.

Run RSTOBJ for each library saved by SAVCHGOBJ on the most recent daily tape.Then run RSTLIB (*NONSYS) OPTION(*NEW) to restore the remaining libraries and objects from the SAVE 21 weekly save.

D.

For each daily tape, run RSTOBJ for each library saved by SAVCHGOBJ on the daily tapes.Then run RSTOBJ(*NONSYS) OPTION(*NEW) to restore the remaining libraries and objects from the SAVE 21 weekly save.
