Question 1

An administrator wants to check which system tunables have been changed in the system since last boot. Which procedure provides the information needed?

ARun tunsave -f ./currentconfig; more ./currentconfig.

BView the /etc/tunables/currentconfig file and search for change marks in the file.

CRun the no, ioo and scftedo commands with the -cf flag.

DRun lstuncfg -1 I grep -v DEFAULT.

Answer : D

The procedure to check which system tunables have been changed in the system since last boot is to run the 'lstuncfg -1 | grep -v DEFAULT' command. The lstuncfg command is used to display the current configuration of the system tunables. By using the '-1' option, the command will display the system tunables and whether they have been changed since the last system reboot. The 'grep -v DEFAULT' command will filter out the default values, allowing you to see only the tunables that have been changed. This command is available on IBM AIX v7 systems and is documented in the IBM AIX v7 Administrator Specialty Study Guide. For more information, please see the IBM documentation athttps://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds2/lstuncfg.htm.

Question 2

The administrator of an AIX NIM client system has accidentally removed the /etc/niminfo file. Which method is used to rebuild the /etc/niminfo file?

AUse the nimclient command to restore the /etc/niminfo file from the most recent mksysb backup image.

BUse the rep command on the AIX client system to copy the /etc/niminfo file from the NIM master.

CUse the nimclient command on the AIX client system to rebuild the /etc/niminfo file.

DUse the niminit command on the AIX client system to rebuild the /etc/niminfo file.

Answer : D

The niminit command can be used to rebuild the /etc/niminfo file on an AIX NIM client system if it has been accidentally deleted. This command will read the NIM database on the NIM master and generate the /etc/niminfo file accordingly. Reference: IBM AIX v7 Administrator Specialty Study Guide.

Question 3

A SAN administrator increased the size of a LUN device (hdisk) that is being used by a AIX LPAR. However, the system administrator does not see the new size using the lsvg or Ispv commands.

Which command updates the system with the new size?

Achvg -g

Bcfgmgr

Csynclvodm

Dextendpv

Answer : B

The cfgmgr command updates the system configuration database with the current configuration of the devices attached to the system. When the SAN administrator increases the size of a LUN device (hdisk), it is not automatically reflected on the AIX LPAR. Running the cfgmgr command updates the system with the new size information and makes it visible to the system administrator.

Question 4

When configuring an LPAR profile, what is the meaning of CPU Entitlement?

Athe count of virtual CPUs configured on an LPAR

Bthe number of logical CPUs allocated to an LPAR

CSimultaneous Multi Threading setting of an LPAR

Dthe amount of guaranteed CPU time allocated to an LPAR

Answer : D

CPU Entitlement is a setting in the LPAR profile that defines the amount of guaranteed CPU time allocated to an LPAR. This setting is important for workloads that require a steady level of performance, as it guarantees that the LPAR will always have access to a certain percentage of the processing power on the managed system. Reference: IBM AIX v7 Administrator Specialty Study Guide.

Question 5

A customer runs smit on the AIX command line and receives the message below:

1800-005 SMIT requires a minimum of 24 line by 80 column output display.

What can be done to resolve the error?

ASet the TERM variable to smit.

BChange their DISPLAY environment variable.

CResize their window.

DMake sure they are running as the root user.

Answer : C

The root user is not required to run SMIT, and the size of the window is the only factor that determines the minimum output display requirements. According to the IBM AIX v7 Administrator Specialty Study Guide (page 9-3), SMIT requires 24 lines and 80 columns for the output display for successful execution.

Question 6

An application administrator needs an account on the AIX server, but does not know it which group it should belong. What is the default group for AIX users, if one was not specified during creation of the account?

Ano group

Bthe group name will be the same as the user name

Cusers

Dstaff

Answer : C

This is the default primary group for all newly created AIX user accounts. From the IBM AIX v7 Administrator Specialty Study Guide: 'By default, all new user accounts are assigned to the 'users' primary group.'

Question 7

When the system boots it stops and displays reference code 551. This reference code means the rootvg will not varyon. What is the best way for the administrator to proceed?

APerform a debug boot of AIX and diagnose/fix the problem.

BPerform a maintenance mode boot of AIX and diagnose/fix the problem.

CReinstall AIX or restore from a mksysb.

DRestart the system.

Answer : B

This code indicates that the rootvg will not varyon, and performing a maintenance boot allows the administrator to diagnose the issue and fix it. From the IBM AIX v7 Administrator Specialty Study Guide: 'When the system is halted with a reference code 551, the rootvg will not varyon and the system will not boot. The administrator must perform a maintenance mode boot to diagnose the problem.'
