Reference: IBM AIX v7 Administrator Specialty Study Guide, page 546.
NEW QUESTION 33
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. The administrator of the NIM master system attempts to use NIM to install software updates on the NIM client, but receives the error message Permission denied.
What can the administrator of the AIX NIM client do to help resolve the problem?
- A. Check the firewall configuration and open port 1066 if required.
- 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.
- D. Edit the /etc/services file to check the port number used for the nimreg service, then refresh inetd.
Answer: B
Explanation:
When using the connect=shell option, a successful NIM operation requires that the root user on the NIM client has an entry in its .rhosts file for the NIM master, and that the file permissions are set to 600. 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/nim_security.htm.

NEW QUESTION 36
An administrator wants to check which system tunables have been changed in the system since last boot. Which procedure provides the information needed?
- A. View the /etc/tunables/currentconfig file and search for change marks in the file.
- B. Run the no, ioo and scftedo commands with the -cf flag.
- C. Run tunsave -f ./currentconfig; more ./currentconfig.
- 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 37
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. Yes, but they may need to create a spot first.
- B. No, because mksysb is not bootable.
- C. No, because they need to use the original AIX installation media for that server.
- 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 38
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 reduces the failover time to the secondary name server when the first name server is not reachable.
- B. It avoids NFS mounts appearing to be hung or stalled indefinitely when there are network outages.
- 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 39

NEW QUESTION 42
Which command lists filesets that are below AIX V7.2 technology level 4?
- A. lslpp -s -1 7200-04
- B. lppchk: -L -F "fileset level" I grep -v "7200-04"
- C. instfix -i I grep -v 7200-04
- D. oslevel -r -1 7200-04
Answer: D
Explanation:
This command will list all filesets that are below the AIX V7.2 technology level 4. The oslevel command is a useful tool for AIX administrators, as it allows them to list the installed technology levels and filesets. Other commands such as lslpp, lppchk, and instfix are not applicable to this task and will not provide the desired information.
For more information on the oslevel command, please refer to the IBM AIX v7 Administrator Specialty Study Guide, page 12-15. The guide can be found here: https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/os_upgrade/oslevel_command.htm.
NEW QUESTION 43
What are three states a device can have when connected to an AIX system?
- A. Suspended
- B. Stopped
- C. Available
- D. Running
- E. Defined
- F. Blocked
Answer: B,C,E
Explanation:
Explanation
Devices that are connected to the system can be in one of four states.
Devices that are connected to the system can be in one of the following states:
Item
Description
Undefined
The device is unknown to the system.
Defined
Specific information about the device is recorded in the customized database, but it is unavailable to the system.
Available
A defined device is coupled to the operating system, or the defined device is configured.
Stopped
The device is unavailable but remains known by its device driver.
If a tty device and a printer alternately use the same tty connector, both a tty device and a printer are defined on the same parent and port in the device configuration database. Only one of these devices can be configured at a time. When the tty connector is configured, the printer specific setup information is retained until it is configured again. The device is not removed; it is in the defined state. Maintaining adevice in defined state retains customized information for a device that is not currently in use, either before it is first made available or while it is temporarily removed from the system.
If a device driver exists for a device, the device can be made available through the device driver.
