Question 1

An administrator starts an AIX LPAR and wants to monitor the boot process using the HMC console.

Which command in HMC SSH session lists all managed systems, LPARs on them and offers an easy way to open a console window to an AIX LPAR?

Amkvterm

Blsrefcode

Clssyscfg

Dvtmenu

Answer : C

According to the IBM AIX v7 Administrator Specialty Study Guide, the lssyscfg command is used to display detailed information about a system configuration. It can also be used to open a virtual terminal session to an AIX LPAR.

Question 2

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 3

What is a benefit of using mksysb to backup a system?

AThe image contains a backup of all file systems.

BThe image can be used to restore the rootvg volume group of the system.

CThe image contains a backup of all application and user data.

DThe image contains a backup of all volume groups and logical volumes.

Answer : B

The mksysb command is used to create a backup image of an AIX system. This image contains a backup of the rootvg volume group of the system, which includes all the operating system files, configuration files and installed applications. This is documented in the IBM AIX v7 Administrator Specialty Study Guide. More information on this can be found athttps://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/com.ibm.aix.cmds3/mksysb.htm.

Question 4

Which two additional commands should an AIX V7.2 administrator run after mirroring the rootvg with mirrorvg command?

Abosboot

Bvaryonvg

Cbootlist

Dreboot

Esynclvodro

Answer : A, C

The two additional commands that an AIX V7.2 administrator should run after mirroring the rootvg with the mirrorvg command are 'bosboot' and 'bootlist'. The bosboot command is used to update the boot image on all disks in the volume group, and the bootlist command is used to set the boot order for the system. These commands are available on IBM AIX v7 systems and are 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.cmds3/bosboot.htmandhttps://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds3/bootlist.htm.

Question 5

An IT security department would like to limit root user access to only members of the group called system. Which command will accomplish this?

Achgroup admin=root system

Bcruiser sugroups=system root

Cchadmin user=root system

Dchadmin group=system root

Answer : D

The 'chadmin' command can be used to modify the attributes of a user account, including the groups that the user belongs to. The syntax for limiting root user access to members of the group called 'system' would be:

sql

chadmin group=system root

This command will add the root user to the 'system' group and remove it from any other groups. Members of the 'system' group will be the only ones able to access the root account.

Question 6

An administrator has a test server (my host) that uses local name resolution. The administrator arrives late one morning and finds that their co-worker was asked to make some changes to the IP address of the server.

The co-worker used SMIT from the console, but then when testing from the console, the following command fails:

ping my_host

Why did the ping fail?

AThey didn't update /etc/hosts after mktcpip was run.

BThey used an incorrect gateway address.

CThey didn't update the DNS entry.

DThey didn't reboot the server.

Answer : A

The /etc/hosts file is used by the system for local name resolution on the server, so if the IP address of the server has been changed, but the /etc/hosts entry has not been updated, the ping command will fail. This is explained in the IBM AIX v7 Administrator Specialty Study Guide, under the topic 'Using the mktcpip Command'.

Question 7

Which file starts the System Resource Controller?

A/etc/rc.d/rc.2

B/etc/rc.srcmstr

C/etc/rc.local

D/etc/inittab

Answer : B

The System Resource Controller (SRC) is the main process that starts other background processes when the system boots. It is started through the /etc/rc.srcmstr script which is run by the init process. This script reads the /etc/inittab file and starts the necessary processes.
