IBM S1000-007 IBM AIX v7 Administrator Specialty Exam Practice Test

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.

This is the default primary group for all newly created AIX user accounts. From the IBM AIX v7 Administrator Specialty Study Guide: "By default, all new user accounts are assigned to the 'users' primary group."

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:

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 

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).

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.
