• A.Because there is an Unbreakable Enterprise Kernel installed, it must be the default kernel listed as shown by the default=0 directive.
• B.The root directive specifies an initial root filesystem, allowing access to block device modules to mount the real root filesystem on disk.
• C.(hd0, 0) represents the first partition on the first drive detected by the BIOS.
• D.Each kernel must have an initramfs that matches the version of the kernel.
• E.The initrd directive specifies the initamfs, an initial root filesystem in RAM, allowing access to block device modules to mount the real root filesystem.
• F.(hd0, 0) represents the first partition on device /dev/hd0.
• G.The hiddenmenu directive hides the GRUB menu only for 5 seconds after which it becomes visible again.

You recently updated the strace package to the latest version as shown:

What is the outcome of running this command?

• A.It will prompt you to select a version of the strace package that you want to downgrade.
• B.It downgrades strace package to version 4.5.19-1.11.e16_3.2.
• C.It downgrades the strace package to version 4.5.19-1.6.e16.
• D.It fails with an error because you cannot downgrade a package using the yum command.
• E.It fails with an error because there are multiple versions available to which Yum can downgrade the strace package.

Examine the files and directories shown:


What is the reason for this configuration? (Choose the best answer.)

• A.The links in /etc to the directories in /etc/rc.d are provided to permit one set to have different owners or ppermissions than the other
• B.The links in /etc to the directories in /etc/rc.d are not required and must have been added by the administrator
