D. High ambient temperature has forced the drives to temporarily run slower.

An administrator plans to save all the system values from the source system and restore them on the target system. Which pair of actions will do this?

A. PRTSYSINE and save the QSYSPRT generated spool file on the source system Restore the spool file and RTVSYSINE FILE(QSYSPRT) on the target system

B. RTVSYSINF LIB(LIBA) and save the LIBA library on the source systemRestore the LIBA library and UPDSYSINF LIB(LIBA) TYPE(*SYSVAL) on the target system

C. RTVSYSVAL SYSVAL(*ALL) LIB(LIBA) and save the LIBA library on the source system Restore the LIBA library and UPDSYSVAL LIB(LIBA) SYSVAL(*ALL) on the target system

D. WRKSYSVAL SYSVAL(*ALL) OUTPUT(*OUTFILE) FILE(ABC) and save the ABC file on the source system Restore the ABC file and RTVSYSVAL SYSVAL(*ALL) FILE(ABC) on the target system

Which tool should the administrator use to support this requirement?

A. IBM i Performance Explorer (PEX)

B. IBM System Director Navigator for i

C. System i Navigator Management Central

D. IBM Performance Management for Power Systems

An administrator is working with users to enable them to control printers in their various departments. The required security must enable only control of the departmental printers to users in that department, as well as restricting others from

using them.

What should the administrator do for each department to support these requirements?

A. Change the output queue "authority to check" parameter to *DTAAUT.Change the *PUBLIC authority for the output queues and devices to *EXCLUDEGrant each user *CHANGE authority to each device description and output queue.

B. Create a group profile to own the output queue and device decryption.Change the ownership of the output queue and device description to the new profile.Make the users members of the group profile.Grant the group profile *SPLCTL special authority.

C. Create a group profile to own the output queue and device decryption.Change the ownership of the output queue and device description to the new profile.Make the users members of the group profile.Grant the group profile *JOBCTL special authority.

D. Create an authorization list for the departments printers.Assign the output queues and device descriptions to the authorization list.Change the output queue "authority to check" parameter to *DTAAUT.Change the *PUBLIC authority to *EXCLUDE.Add each user to the authorization list with *CHANGE authority.
