"The command to limit root user access to only members of the group called system is chadmin group=system root. This command will set the primary group of the root user to the system group, thereby limiting root user access to only members of that group. This command can be used to set any user's primary group, not just root." The source of this information is the IBM AIX v7 Administrator Specialty Study Guide.
質問 # 18
An IT security department would like to limit root user access to only members of the group called system. Which command will accomplish this?
- A. chgroup admin=root system
- B. chadmin group=system root
- C. cruiser sugroups=system root
- D. chadmin user=root system
正解：B
解説：
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.

解説：
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.

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 that the root user's .rhosts file has an entry for the NIM master, and that the file permissions are 600.
- B. Flush the arp cache and then reboot the client system to ensure the network route table is correct.
- C. Check the firewall configuration and open port 1066 if required.
- D. Edit the /etc/services file to check the port number used for the nimreg service, then refresh inetd.
正解：A
解説：
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.

質問 # 27
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 lstuncfg -1 I grep -v DEFAULT.
- B. View the /etc/tunables/currentconfig file and search for change marks in the file.
- C. Run tunsave -f ./currentconfig; more ./currentconfig.
- D. Run the no, ioo and scftedo commands with the -cf flag.
正解：A
解説：
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.
質問 # 28
Which command should be used to perform a graceful shutdown and reboot of an AIX LPAR?
- A. halt
- B. shutdown
- C. reboot
- D. bosboot
正解：B
解説：
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.

- A. Use the niminit command on the AIX client system to rebuild the /etc/niminfo file.
- B. Use the rep command on the AIX client system to copy the /etc/niminfo file from the NIM master.
- C. Use the nimclient command on the AIX client system to rebuild the /etc/niminfo file.
- D. Use the nimclient command to restore the /etc/niminfo file from the most recent mksysb backup image.
正解：A
解説：
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.
質問 # 31

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?
- A. They didn't update the DNS entry.
- B. They used an incorrect gateway address.
- C. They didn't update /etc/hosts after mktcpip was run.
- D. They didn't reboot the server.
正解：C
解説：
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".
質問 # 36
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 machine resource first.
- B. Yes, but they may need to create a spot first.
- C. No, because mksysb is not bootable.
- D. No, because they need to use the original AIX installation media for that server.
正解：C
質問 # 37
