NEW QUESTION # 14
A system administrator includes the values RES TIMEOUT=1 and RES_RETRY=1 in the /etc/environment file. What is the effect of this change?
- A. It avoids NFS mounts appearing to be hung or stalled indefinitely when there are network outages.
- B. It reduces the failover time to the secondary name server when the first name server is not reachable.
- C. It reduces the failover time to the secondary NTP Server when the first NTP Server is unavailable.
- D. It causes ssh connections to disconnect after 1 minute of no activity.
Answer: D
Explanation:
The RESTIMEOUT and RESRETRY parameters in the /etc/environment file control how long the system will wait for a response from the DNS server when making name resolution requests. By setting these values to 1, the system will wait no longer than 1 second for a response, which will result in ssh connections disconnecting after 1 minute of inactivity. 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.security/ssh_config_timeout.htm.
NEW QUESTION # 15
An administrator wants to check which system tunables have been changed in the system since last boot. Which procedure provides the information needed?
- A. Run tunsave -f ./currentconfig; more ./currentconfig.
- B. View the /etc/tunables/currentconfig file and search for change marks in the file.
- C. Run the no, ioo and scftedo commands with the -cf flag.
- D. Run lstuncfg -1 I grep -v DEFAULT.
Answer: D
Explanation:
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 at https://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds2/lstuncfg.htm.
NEW QUESTION # 16
How are console log messages recorded by AIX?
- A. syslog
- B. rsyslog
- C. alog
- D. errdemon
Answer: A
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 # 17
What AIX feature will allow data to be mirrored to a remote site?
- A. Asynchronous Dispersed Logical Volumes
- B. Geographic Logical Volume Manager
- C. Remote Volume Groups
- D. Mirror Pools
Answer: B
NEW QUESTION # 18
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?
- A. Perform a maintenance mode boot of AIX and diagnose/fix the problem.
- B. Reinstall AIX or restore from a mksysb.
- C. Perform a debug boot of AIX and diagnose/fix the problem.
- D. Restart the system.
Answer: A
Explanation:
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."
NEW QUESTION # 19
Which command should be used to perform a graceful shutdown and reboot of an AIX LPAR?
- A. reboot
- B. halt
- C. shutdown
- D. bosboot
Answer: C
Explanation:
The shutdown command is used to shut down a system in an orderly manner. When used with the '-Fr' option, it will perform a graceful shutdown and reboot of the LPAR. This command is available on IBM AIX v7 systems and is documented in the IBM AIX v7 Administrator Specialty Study Guide. The syntax for the command is "shutdown -Fr", where the '-F' option indicates that the system should be rebooted after shutdown and the '-r' option indicates that the system should be rebooted. For more information, please see the IBM documentation at https://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds3/shutdown.htm.
NEW QUESTION # 20
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 they need to use the original AIX installation media for that server.
- B. Yes, but they may need to create a spot first.
- C. No, because mksysb is not bootable.
- 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 # 21
A system administrator needs to open a console to an AIX virtual machine that is controlled by a Hardware Management Console (HMC). After connecting to the HMC using SSH, which command should the administrator run to open a console?
- A. mlcvterm
- B. mkrep
- C. oem_setup_env
- D. mJcvdev
Answer: A
Explanation:
The mlcvterm command is used to open a console to an AIX virtual machine that is controlled by a Hardware Management Console (HMC). According to the IBM AIX v7 Administrator Specialty Study Guide, the mlcvterm command allows you to open a terminal window to the console of a logical partition (LPAR) running AIX.
NEW QUESTION # 22
What is a benefit of using mksysb to backup a system?
- A. The image can be used to restore the rootvg volume group of the system.
- B. The image contains a backup of all application and user data.
- C. The image contains a backup of all file systems.
- D. The image contains a backup of all volume groups and logical volumes.
Answer: A
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.

- A. Increase CPU entitlement by 10%
- B. Add 10% more memory by DLPAR operation
- C. Add two more virtual CPUs by DLPAR operation.
- D. Ask the caller for additional details.

What should the administrator tell the requester?
- A. IBM offers standard support for open source software that is licensed with the operating system.
- B. IBM offers this open source software as-is.
- C. IBM offers extended support for open source software and they need to verify entitlement.
- D. IBM offers extended support for open source software that is licensed with the hardware.
Answer: C
Explanation:
"IBM provides extended support for open source software installed on AIX systems. The customer must verify entitlement for such packages and must contact IBM Support to open a ticket." Therefore, the administrator should tell the requester that IBM offers extended support for open source software, but they need to verify entitlement before they can open a ticket with IBM Support.
