Which two additional commands should an AIX V7.2 administrator run after mirroring the rootvg with mirrorvg command?
How are console log messages recorded by AIX?
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.

An administrator wants to check which system tunables have been changed in the system since last boot. Which procedure provides the information needed?
A customer calls to complain about slow workload performance but offers no additional details. What should the administrator do next?
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).
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?
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).
