質問 # 27
While a system administrator is checking the TCP/IP connectivity between two systems with the traceroute command, the administrator found Fragmentation required messages in the traceroute output.
What is the likely reason for these messages?
- A. The TCP buffers between the source and the target systems are exhausted. The source and target systems are using virtual ethernet adapters.
- B. Different MTU sizes between the source and target systems. The source system is using Jumbo Frames and the target is using the default MTU size.
- C. The TCP buffers in the router gateway are exhausted. The source and target system are having TCP/IP communication problems.
- D. Same MTU sizes between the source and target systems. The source and target systems are using Jumbo Frames. The LPARs are using the same Virtual Switch (vSwitch) Network.
正解：B
質問 # 28
What AIX feature will allow data to be mirrored to a remote site?
- A. Asynchronous Dispersed Logical Volumes
- B. Mirror Pools
- C. Remote Volume Groups
- D. Geographic Logical Volume Manager
正解：D
解説：
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.
質問 # 29
When configuring an LPAR profile, what is the meaning of CPU Entitlement?
- A. the amount of guaranteed CPU time allocated to an LPAR
- B. the number of logical CPUs allocated to an LPAR
- C. the count of virtual CPUs configured on an LPAR
- D. Simultaneous Multi Threading setting of an LPAR
正解：A
解説：
CPU Entitlement is a setting in the LPAR profile that defines the amount of guaranteed CPU time allocated to an LPAR. This setting is important for workloads that require a steady level of performance, as it guarantees that the LPAR will always have access to a certain percentage of the processing power on the managed system. Reference: IBM AIX v7 Administrator Specialty Study Guide.
質問 # 30
Which two additional commands should an AIX V7.2 administrator run after mirroring the rootvg with mirrorvg command?
- A. reboot
- B. bosboot
- C. varyonvg
- D. bootlist
- E. synclvodro
正解：B、D
解説：
The two additional commands that an AIX V7.2 administrator should run after mirroring the rootvg with the mirrorvg command are 'bosboot' and 'bootlist'. The bosboot command is used to update the boot image on all disks in the volume group, and the bootlist command is used to set the boot order for the system. These commands are available on IBM AIX v7 systems and are 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.cmds3/bosboot.htm and https://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds3/bootlist.htm.
質問 # 31
Which logical volume Mirror Write Consistency policy should an AIX V7.2 administrator use to achieve the data consistency between mirrors?
- A. active
- B. off
- C. round robin
- 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 # 32

Which procedure provides the information needed?
- A. Run the no, ioo and scftedo commands with the -cf flag.
- B. Run lstuncfg -1 I grep -v DEFAULT.
- C. View the /etc/tunables/currentconfig file and search for change marks in the file.
- D. Run tunsave -f ./currentconfig; more ./currentconfig.
正解：B
質問 # 33
When attempting to recover a corrupted file system an administrator runs the command fsckagainst 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. Run fsck: with the -F (force) flag.
- B. Convert the log to INLINE.
- C. Run logform /dev/u1v11.
- D. Run logrcvr /dev/ulv14 .
正解：C
質問 # 34
While trying to extend a file system named /work an administrator receives the following error. 0516-787 extendlv: Maximum allocation for logical volume fslv00 is 256.
What must be done to allow the file system to be extended?
- A. Increase the volume group's maximum limit of logical partitions per logical volume.
- B. Change the logical volume type to jfs2 as JFS logical volumes cannot extend past 256.
- C. Increase the setting for maximum number of logical partitions for that logical volume.
- D. Change the file system's maximum capacity.
正解：C
質問 # 35
Which statement is true regarding the snap command?
- A. It collects performance related data.
- B. The data must be stored in /tmp.
- C. By default, it will check there is enough space where the data is to be stored.
- D. All options are enabled by default.
正解：A
質問 # 36
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 is incorrectly hashing the UDID of the disk.
- C. lspv shows the contents of the ODM.
- D. The system has the wrong version of the lspv command installed.
正解：C
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 # 37
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 is incorrectly hashing the UDID of the disk.
- C. lspv shows the contents of the ODM.
- D. The system has the wrong version of the lspv command installed.
正解：D
質問 # 38
An administrator has configured NFS export in the /etc/exports file. Based on the following output, with which permissions has the /tmp directory been exported?
- A. read-write permissions
- B. read-only permissions
- C. write-only permissions
- D. no permissions
正解：A
質問 # 39
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. Flush the arp cache and then reboot the client system to ensure the network route table is correct.
- B. Edit the /etc/services file to check the port number used for the nimreg service, then refresh inetd.
- C. Check the firewall configuration and open port 1066 if required.
- D. Check that the root user's .rhosts file has an entry for the NIM master, and that the file permissions are
600.
正解：B
質問 # 40
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 causes ssh connections to disconnect after 1 minute of no activity.
- C. It avoids NFS mounts appearing to be hung or stalled indefinitely when there are network outages.
- D. It reduces the failover time to the secondary NTP Server when the first NTP Server is unavailable.
正解：C
質問 # 41
A customer calls to complain about slow workload performance but offers no additional details. What should the administrator do next?
- A. Add 10% more memory by DLPAR operation
- B. Add two more virtual CPUs by DLPAR operation.
- C. Increase CPU entitlement by 10%
- D. Ask the caller for additional details.
正解：D
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).
