Three of the 155 questions in this pack

Question 1

A Linux administrator needs to create and then connect to the app-01-image container. Which of the following commands accomplishes this task?

  1. docker run -it app-01-image
  2. docker start -td app-01-image
  3. docker build -ic app-01-image
  4. docker exec -dc app-01-image
Show answer and explanation

Correct answer: A. docker run -it app-01-image

The `docker run -it app-01-image` command creates a new container from the specified image and connects to it interactively. The `-i` flag keeps STDIN open even if not attached, and `-t` allocates a pseudo-terminal, allowing the administrator to interact with the running container immediately.

Why the other options are wrong

  • B. docker start is used to start an existing stopped container, not create a new one from an image.
  • C. docker build is used to build images from a Dockerfile, not create or connect to containers.
  • D. docker exec runs commands in an already-running container; it cannot be used to initially create and connect to a container.

Question 2

To perform a live migration, which of the following must match on both host servers? (Choose two).

  1. USB ports
  2. Network speed
  3. Available swap
  4. CPU architecture
  5. Available memory
  6. Disk storage path ✅Correct Answer: D, F
  7. CPU architecture
  8. Disk storage path Live migration requires the same CPU architecture on both hosts so the guest's instruction set stays valid, and it requires the VM's disk to be reachable at the same storage path on each host, normally shared storage mounted identically. A mismatch in either one causes the migration to fail.

Question 3

A Linux systems administrator needs to extract the contents of a file named /home/dev/web.bkp to the /var/www/html/ directory. Which of the following commands should the administrator use?

  1. cd /var/www/html/ && gzip -c /home/dev/web.bkp | tar xf -
  2. pushd /var/www/html/ $$ cpio -idv < /home/dev/web.bkp && popd
  3. tar -c -f /home/dev/web.bkp /var/www/html/
  4. unzip -c /home/dev/web.bkp /var/www/html/
Show answer and explanation

Correct answer: A. cd /var/www/html/ && gzip -c /home/dev/web.bkp | tar xf -

- Only this option moves into the destination directory first and then feeds the backup file through a pipe to `tar xf -`, where `-x` extracts and `-f -` reads the archive stream from standard input, so the contents land in /var/www/html/. In practice the decompression flag is `-dc` (or zcat).

Why the other options are wrong

  • B. `$$` is not a valid command separator (it should be `&&` or `;`), and cpio expects a cpio-format stream.
  • C. tar `-c` creates an archive instead of extracting, and the paths are reversed for this task.
  • D. unzip handles ZIP archives only, and this syntax would not extract into the target directory.

What makes the Linux+ hard

The XK0-006 is a significant step up from older Linux+ versions. It covers cloud integration, automation, scripting and security alongside traditional Linux administration, and it includes performance-based questions where you have to complete real tasks in a simulated terminal that you cannot guess your way through.

This pack has 155 practice questions for the XK0-006, every MCQ and PBQ in one place, so the question style and the PBQ format are familiar before test day.
