A server administrator recently installed a kernel update to test functionality Upon reboot, the administrator determined the new kernel was not compatible with certain server hardware and was unable to uninstall the update. Which of the following should the administrator do to mitigate further issues with the newly instated kernel version?
正解:A
The bootloader configuration file is used to specify which kernel version and options to use when booting the system. The first kernel stanza in the file is the default one that is loaded automatically. By editing this stanza and changing it to point to the last known-good kernel files, the administrator can boot the system with a working kernel and avoid any compatibility issues with the new kernel update.
