Explanation:
The istat command displays information about the inode of a file, including the last access time. 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 "istat file", where 'file' is the path to the file you would like to check. For more information, please see the IBM documentation at https://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds2/istat.htm.
NEW QUESTION # 28
Which user account is always UID 0 on AIX?
- A. system
- B. bin
- C. admin
- D. root
Answer: D
Explanation:
Explanation
The root account is the special user in the /etc/passwd file with the user ID (UID) of 0 and is commonly given the user name, root. It is not the user name that makes the root account so special, but the UID value of 0. This means that any user that has a UID of 0 also has the same privileges as the root user. Also, the root account is always authenticated by means of the local security files.

NEW QUESTION # 31
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. Run logform /dev/u1v11.
- B. Convert the log to INLINE.
- C. Run logrcvr /dev/ulv14 .
- D. Run fsck: with the -F (force) flag.
Answer: D
Explanation:
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).
NEW QUESTION # 32
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 NTP Server when the first NTP Server is unavailable.
- B. It causes ssh connections to disconnect after 1 minute of no activity.
- C. It reduces the failover time to the secondary name server when the first name server is not reachable.
- D. It avoids NFS mounts appearing to be hung or stalled indefinitely when there are network outages.
Answer: B
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 # 33
A system administrator has noticed that static routes are missing after rebooting a system. What is the most likely reason for this?
- A. The administrator has failed to configure the routes in the lo0 device with the chdev command.
- B. The administrator has failed to configure the routes with the route add command.
- C. The administrator has failed to configure the routes in the inet0 device with the chdev command.
- D. The administrator has failed to run the cfgmgr command before rebooting the systems.
Answer: D
Explanation:
The administrator has failed to run the cfgmgr command before rebooting the systems. Running the cfgmgr command before rebooting a system is important, as it ensures that any changes made to the configuration are written to the system, otherwise the changes may be lost when the system is rebooted. Other commands such as chdev and route add are not related to this issue and will not solve the problem.
For more information on the cfgmgr command, please refer to the IBM AIX v7 Administrator Specialty Study Guide, page 10-7. The guide can be found here: https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/cfgmgmt/cfgmgr_command.htm.
NEW QUESTION # 34
Which AIX command displays the types, counts, and percentages of LPAR memory?
- A. vmstat -v
- B. Ivmo -a -v rootvg
- C. iostat
- D. mpstat -w 1
Answer: A
Explanation:
The vmstat command is used to display the types, counts, and percentages of LPAR memory. The -v flag is used to display the virtual memory statistics, including the types and counts of memory. Reference: IBM AIX v7 Administrator Specialty Study Guide (page 6-17).
NEW QUESTION # 35
What are three states a device can have when connected to an AIX system?
- A. Running
- B. Available
- C. Suspended
- D. Defined
- E. Stopped
- F. Blocked
Answer: B,D,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.

NEW QUESTION # 36
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. 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.
- B. 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.
- C. The TCP buffers in the router gateway are exhausted. The source and target system are having TCP/IP communication problems.
- D. The TCP buffers between the source and the target systems are exhausted. The source and target systems are using virtual ethernet adapters.
Answer: A
Explanation:
The source system is using Jumbo Frames and the target is using the default MTU size. Fragmentation required messages can appear in traceroute output when the Maximum Transmission Unit (MTU) size of the source and target systems are different. In this case, the source system is using a larger MTU size (Jumbo Frames) than the target system (default MTU size). As a result, the router gateway must fragment the data packets in order for them to reach their destination. This is why the fragmentation required messages appear in the traceroute output.

NEW QUESTION # 37
What is a benefit of using mksysb to backup a system?
- A. The image contains a backup of all volume groups and logical volumes.
- B. The image contains a backup of all file systems.
- C. The image can be used to restore the rootvg volume group of the system.
- D. The image contains a backup of all application and user data.
Answer: C
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.
