1. Question 1103 GNU and Unix Commands

   A user wants to rerun the most recent bash command that begins with ssh without retyping it. Which input does this?

   1. ATyping %ssh at the prompt
   2. BTyping !! at the prompt
   3. CTyping $ssh at the prompt
   4. DTyping !ssh at the prompt
   Show answer and explanationHide answer

   Correct answer: D

   !ssh is history expansion that reruns the latest command starting with ssh. !! reruns the previous command in full, $ssh expands a shell variable named ssh, and %ssh refers to a job in job control rather than the history.

2. Question 2104 Devices, Linux Filesystems, Filesystem Hierarchy Standard

   A newly created partition /dev/sdb1 must be formatted with the ext4 filesystem. Which command creates the filesystem on it?

   1. Afsck.ext4 /dev/sdb1
   2. Bfdisk /dev/sdb1
   3. Cmkfs.ext4 /dev/sdb1
   4. Dmount /dev/sdb1 /mnt
   Show answer and explanationHide answer

   Correct answer: C

   mkfs.ext4 writes a new ext4 filesystem onto the partition. fsck.ext4 checks an existing filesystem, fdisk edits partition tables rather than creating filesystems, and mount attaches a filesystem to the directory tree.

3. Question 3102 Linux Installation and Package Management

   Which two statements about Debian package tools are accurate? (Choose two.)

   1. Adpkg installs or removes a single .deb file without fetching its missing dependencies from repositories
   2. Bapt cannot install a .deb file that is stored on the local disk
   3. Capt uses the configured repository lists to resolve and download the dependencies of a package
   4. Ddpkg reads the repository list in /etc/apt/sources.list to resolve dependencies
   Show answer and explanationHide answer

   Correct answer: A, C

   dpkg works only on the package file it is given and does not download missing dependencies, while apt consults the configured repositories to resolve and fetch them. apt can install a local .deb by path, and dpkg does not use the apt repository list at all.

4. Question 4101 System Architecture

   An administrator is installing Linux on a new server that uses UEFI firmware. Which partition must the firmware be able to read so it can locate and start the bootloader?

   1. AThe BIOS boot partition
   2. BThe swap partition
   3. CThe EFI System Partition
   4. DThe root partition formatted as XFS
   Show answer and explanationHide answer

   Correct answer: C

   UEFI firmware loads boot files from the EFI System Partition, a FAT-formatted partition that holds the bootloader binaries. The BIOS boot partition serves GRUB on GPT disks under legacy BIOS, swap is used for paging, and firmware does not read the root filesystem directly.

5. Question 5103 GNU and Unix Commands

   A script must show only the first ten lines of a large text file on standard output. Which filter does this by default?

   1. Atail
   2. Btac
   3. Cwc
   4. Dhead
   Show answer and explanationHide answer

   Correct answer: D

   head prints the first ten lines of its input by default. tail prints the last lines, tac prints lines in reverse order, and wc counts lines, words and bytes instead of showing the text.
