An AIX administrator installed the fileset named useful_fileset. How can they determine which files are included in the fileset?
- A. rpm -qf useful_fileset
- B. lppchk -f useful fileset
- C. lslpp -f useful_fileset
- D. file -f useful__fileset
Answer: C
Explanation:
The "lslpp" command can be used to display information about filesets installed on an AIX system. To determine which files are included in the "useful_fileset" fileset, the administrator can run the following command:
lslpp -f useful_fileset
This command will display detailed information about the "useful_fileset" fileset, including a list of the files that are included in the fileset. This information can be useful for verifying the installation of the fileset and for troubleshooting problems that may be related to the fileset.
NEW QUESTION 22

NEW QUESTION 24
A system administrator has noticed that static routes are missing after rebooting a system. What is the most likely reason for this?
- A. The administrator has failed to configure the routes in the inet0 device with the chdev command.
- B. The administrator has failed to configure the routes in the lo0 device with the chdev command.
- C. The administrator has failed to configure the routes with the route add command.
- D. The administrator has failed to run the cfgmgr command before rebooting the systems.
Answer: D
Explanation:
The administrator has failed to run the cfgmgr command before rebooting the systems. Running the cfgmgr command before rebooting a system is important, as it ensures that any changes made to the configuration are written to the system, otherwise the changes may be lost when the system is rebooted. Other commands such as chdev and route add are not related to this issue and will not solve the problem.
For more information on the cfgmgr command, please refer to the IBM AIX v7 Administrator Specialty Study Guide, page 10-7. The guide can be found here: https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/cfgmgmt/cfgmgr_command.htm.
NEW QUESTION 25
What command is used to monitor SAN I/O performance/throughput?
- A. vmstat -i 1
- B. iostat -DIRT 60 10
- C. mpstat -w 1
- D. ioo -L
Answer: B
Explanation:
The command used to monitor SAN I/O performance/throughput is iostat -DIRT 60 10. The iostat command is used to monitor I/O performance and throughput on a SAN device. The DIRT (Disk I/O Response Time) flag can be used to display the response time for each I/O request. The last two arguments, 60 and 10, are the interval (in seconds) and the number of iterations respectively. This command will monitor I/O performance/throughput every 60 seconds for 10 iterations.

NEW QUESTION 28
An AIX system is defined as a NIM client with -a connect=shell. The client system is up and running. The client can ping the NIM master, and the master can ping the client.

What can the administrator of the AIX NIM client do to help resolve the problem?
- A. Edit the /etc/services file to check the port number used for the nimreg service, then refresh inetd.
- B. Check that the root user's .rhosts file has an entry for the NIM master, and that the file permissions are
600. - C. Flush the arp cache and then reboot the client system to ensure the network route table is correct.

Answer: A
NEW QUESTION 29
An administrator finds that their development server has crashed and an error code 554 is displayed. They know that this error is typically associated with a problem executing varyon rootvg and they should boot from AIX Media to be able to perform maintenance tasks. When the administrator checks the crontab of the NIM server, they find that a mksysb image is created each night.
Can the administrator use this mlcsysb to boot the server and perform the required maintenance tasks?
- A. No, because mksysb is not bootable.
- B. No, because they need to use the original AIX installation media for that server.
- C. Yes, but they may need to create a spot first.
- D. Yes, but they may need to create a machine resource first.
Answer: D
Explanation:
A mksysb image is a snapshot of the AIX operating system and its configuration, so it can be used to boot the server and perform the required maintenance tasks. However, in order to use the mksysb image, the administrator may need to create a machine resource in the NIM environment first. According to the IBM AIX v7 Administrator Specialty Study Guide (page 13-6), the mksysb image should be used in combination with a previously created machine resource, which defines the parameters for the installation.
NEW QUESTION 30

- D. rpm
Answer: D
NEW QUESTION 31

- B. Use the nimclient command to restore the /etc/niminfo file from the most recent mksysb backup image.
- C. Use the nimclient command on the AIX client system to rebuild the /etc/niminfo file.
- D. Use the rep command on the AIX client system to copy the /etc/niminfo file from the NIM master.
Answer: B

NEW QUESTION 35
What is a benefit of using mksysb to backup a system?
- A. The image contains a backup of all volume groups and logical volumes.
- B. The image can be used to restore the rootvg volume group of the system.
- C. The image contains a backup of all application and user data.
- D. The image contains a backup of all file systems.
Answer: B
Explanation:
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 at https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/com.ibm.aix.cmds3/mksysb.htm.
NEW QUESTION 36
How are console log messages recorded by AIX?
- A. alog
- B. syslog
- C. rsyslog
- D. errdemon
Answer: B
Explanation:
AIX provides the syslog service to record console log messages. The syslog service is used to control the logging of system messages and can be used to record and store the log messages in different formats. The syslog service is enabled through the use of the alog and errdemon commands. The alog command is used to view the log messages that are stored in the /var/adm/syslog/syslog.log file, while the errdemon command is used to control the logging of system messages. Reference: IBM AIX v7 Administrator Specialty Study Guide.
NEW QUESTION 37
What AIX feature will allow data to be mirrored to a remote site?
- A. Remote Volume Groups
- B. Geographic Logical Volume Manager
- C. Asynchronous Dispersed Logical Volumes
- D. Mirror Pools
Answer: B
Explanation:
Geographic Logical Volume Manager (GLVM) is an AIX feature that allows data to be mirrored to a remote site [1][2], enabling disaster recovery and improved data availability. GLVM creates a single, unified view of the data across multiple sites, allowing the data to be managed and accessed as if it was all stored in one location. Reference: IBM AIX v7 Administrator Specialty Study Guide, page 546.
NEW QUESTION 38
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?
- A. synclvodm
- B. extendpv
- C. chvg -g
- D. cfgmgr
Answer: D
Explanation:
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.
