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

AIX provides the syslog service to record console log messages. The syslog service is used to control the logging of system messages and can be used to record and store the log messages in different formats. The syslog service is enabled through the use of the alog and errdemon commands. The alog command is used to view the log messages that are stored in the /var/adm/syslog/syslog.log file, while the errdemon command is used to control the logging of system messages. Reference: IBM AIX v7 Administrator Specialty Study Guide.

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).

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.

The cfgmgr command updates the system configuration database with the current configuration of the devices attached to the system. When the SAN administrator increases the size of a LUN device (hdisk), it is not automatically reflected on the AIX LPAR. Running the cfgmgr command updates the system with the new size information and makes it visible to the system administrator.

"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.

The root user is not required to run SMIT, and the size of the window is the only factor that determines the minimum output display requirements. According to the IBM AIX v7 Administrator Specialty Study Guide (page 9-3), SMIT requires 24 lines and 80 columns for the output display for successful execution.
