質問 # 20
An AIX administrator installed the fileset named useful_fileset. How can they determine which files are included in the fileset?
- A. lslpp -f useful_fileset
- B. file -f useful__fileset
- C. lppchk -f useful fileset
- D. rpm -qf useful_fileset
正解：A
解説：
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.
質問 # 21
When a user logs in. the processing of their .profile is very slow. Which issue could contribute to the problem?
- A. The user's home file system is full.
- B. Network issues between the user location and the system.
- C. A slow NFS mount for their home directory.
- D. The PATH variable contains non-existent directories.
正解：D
解説：
When a user logs in, the system will process their .profile file which contains the PATH variable. This variable specifies the list of directories that the system will search through to locate executable files. If the PATH variable contains non-existent directories, then it will take longer for the system to process the .profile file, resulting in a slower login experience. Reference: IBM AIX v7 Administrator Specialty Study Guide (page 9-10).
質問 # 22

- B. chadmin user=root system
- C. cruiser sugroups=system root
- D. chadmin group=system root
正解：A
質問 # 23
A client is running multiple AIX, IBM i and Linux partitions on an IBM Power E980 system. Which command allows the administrator to check the number of processors, amount of memory, and list the devices on the AIX partition?
- A. syssnap -gc
- B. lsdev
- C. Iparstat -i
- D. prtconf
正解：D
解説：
This command displays system configuration information, including the number of processors, amount of memory, and list of devices on the AIX partition. This command is part of the AIX Operating System, and is documented in the IBM AIX v7 Administrator Specialty Study Guide. More information on this command can be found at https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/com.ibm.aix.cmds3/prtconf.htm.

Which logical volume Mirror Write Consistency policy should an AIX V7.2 administrator use to achieve the data consistency between mirrors?
- A. round robin
- B. active
- C. off
- D. superstrict
正解：D
解説：
The superstrict mirror write consistency policy is the most reliable policy for achieving data consistency between mirrors in AIX V7.2. This policy will maintain the data consistency between mirrors by writing the data to both mirrors before the write operation is acknowledged as complete. Reference: IBM AIX v7 Administration Specialty Study Guide (section 10.6.2, pp. 651-652).
質問 # 26
Which logical volume Mirror Write Consistency policy should an AIX V7.2 administrator use to achieve the data consistency between mirrors?

質問 # 27
While executing the following extendvg command, the system administrator receives the following error:
The administrator used the chvg -t command to fix the error.
What is the implication of running this command?
- A. It reduces the maximum number of logical volumes allowed within that volume group.
- B. It reduces the maximum number of files allowed within that volume group.
- C. It reduces the maximum file size allowed within that volume group.
- D. It reduces the maximum number of physical volumes allowed within that volume group.
正解：D
解説：
The chvg command with the -t option is used to reduce the maximum number of physical volumes (PVs) allowed in a volume group (VG). This is necessary when the number of PVs in a VG exceeds the maximum allowed. Reference: IBM AIX v7 Administration Specialty Study Guide (section 10.3.3, pp. 641-642).
質問 # 28
When attempting to recover a corrupted file system an administrator runs the command fsck against the unmounted file system and receives the following error:
After confirming that the file system is not mounted, what should the administrator do next?
- A. Convert the log to INLINE.
- B. Run logrcvr /dev/ulv14 .
- C. Run logform /dev/u1v11.
- D. Run fsck: with the -F (force) flag.
正解：D
解説：
When attempting to recover a corrupted file system, the administrator should first confirm that the file system is not mounted. If the file system is not mounted, then the administrator should run the fsck command with the -F (force) flag. This will force the fsck command to check the file system for errors and attempt to fix them. Reference: IBM AIX v7 Administrator Specialty Study Guide (page 8-23).

質問 # 32
A customer added paging space and needs to activate it automatically after the next reboot. Which command should the administrator issue?
- A. swapon
- B. chps
- C. mkps
- D. mklv
正解：C
解説：
The mkps command creates a paging space and activates it when the system is rebooted. This is explained in the IBM AIX v7 Administrator Specialty Study Guide, under the topic "Creating and Activating a Paging Space".
質問 # 33
The lspv and Iquerypv commands show a different PVID for an hdisk. How is this possible?
- A. lspv is querying a disk at a different location.
- B. lspv shows the contents of the ODM.
- C. The system has the wrong version of the lspv command installed.
- D. lspv is incorrectly hashing the UDID of the disk.
正解：B
解説：
The lspv command displays information about physical volumes on the system, and it retrieves the information from the Object Data Manager (ODM). The ODM is the database that stores information about the system's hardware configuration, including the PVID of each disk. The Iquerypv command directly queries the disk for its PVID, and is therefore able to display the correct PVID. Reference: IBM AIX v7 Administrator Specialty Study Guide, page 546.
質問 # 34

質問 # 36
A customer calls to complain about slow workload performance but offers no additional details. What should the administrator do next?
- A. Increase CPU entitlement by 10%
- B. Add 10% more memory by DLPAR operation
- C. Ask the caller for additional details.
- D. Add two more virtual CPUs by DLPAR operation.
正解：C
解説：
When a customer calls with a complaint about slow workload performance, it is important to ask for additional details to help pinpoint the source of the issue. This could include details such as which application or process is running slowly, what errors are appearing, how long the issue has been occurring, etc. Having this information will help the administrator to determine the cause of the problem and determine the best course of action. Reference: IBM AIX v7 Administrator Specialty Study Guide (page 5-29).
質問 # 37
What command is used to monitor SAN I/O performance/throughput?
- A. iostat -DIRT 60 10
- B. ioo -L
- C. vmstat -i 1
- D. mpstat -w 1
正解：A
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.

- A. All file systems defined to the system are mounted
- B. Ail file systems set to mount=true are mounted.
- C. All automatic file systems are mounted.
