An administrator wants to check which system tunables have been changed in the system since last boot. Which procedure provides the information needed?
A.
Run tunsave -f ./currentconfig; more ./currentconfig.
B.
View the /etc/tunables/currentconfig file and search for change marks in the file.
C.
Run the no, ioo and scftedo commands with the -cf flag.
The procedure to check which system tunables have been changed in the system since last boot is to run the 'lstuncfg -1 | grep -v DEFAULT' command. The lstuncfg command is used to display the current configuration of the system tunables. By using the '-1' option, the command will display the system tunables and whether they have been changed since the last system reboot. The 'grep -v DEFAULT' command will filter out the default values, allowing you to see only the tunables that have been changed. This command is available on IBM AIX v7 systems and is 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.cmds2/lstuncfg.htm.
