A Linux administrator needs to create and then connect to the app-01-image container. Which of the following commands accomplishes this task?
docker run -it app-01-image
docker start -td app-01-image
docker build -ic app-01-image
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).
USB ports
Network speed
Available swap
CPU architecture
Available memory
Disk storage path
Show answer and explanation
Correct answer: D, F. CPU architecture; Disk storage path
Live migration moves a running VM between hosts, so both hosts must have compatible CPU architecture for the guest to keep executing the same instructions. The VM's disks must also be reachable at the same storage path on both hosts, typically shared storage, so the destination can open the same disk images. Resources such as memory only need to be sufficient, not identical.
Why the other options are wrong
A. USB ports are peripheral hardware and do not need to match for a live migration.
B. Network speed affects how quickly the migration completes but does not have to be identical on both hosts.
C. Available swap is a host-local resource and does not need to match between hosts.
E. The destination only needs enough free memory for the VM, the amount of available memory does not have to match.
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?
cd /var/www/html/ && gzip -c /home/dev/web.bkp | tar xf -
Correct answer: A. cd /var/www/html/ && gzip -c /home/dev/web.bkp | tar xf -
The command `cd /var/www/html/ && gzip -c /home/dev/web.bkp | tar xf -` changes to the target directory and then extracts the compressed backup file there. The `-c` flag for gzip decompresses to stdout, which is piped to `tar xf -` to extract from stdin, with `-x` extracting and `-f -` reading from stdin.
Why the other options are wrong
B. The syntax uses `$$` which is invalid (should be `;`), and cpio requires different input format than a .bkp file would typically provide.
C. This command uses tar with `-c` (create) mode instead of extract mode, and specifies the wrong paths, effectively creating an archive rather than extracting.
D. unzip is for ZIP archives, not .bkp files; the syntax is also incorrect for extraction to a directory.

Passed. Studying from this pdf actually works. First attempt I only used official material and failed. The difference was very noticeable. Should have used it from the start.

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.

Current version V8, series code XK0-006, launched 15 July 2025, and it is the most significant update in years, adding cloud integration, automation, orchestration, scripting and AI-adjacent content to reflect how Linux is actually used in modern IT environments. It replaced XK0-005 in January 2026 and suits sysadmins, cloud engineers and DevOps professionals who work with Linux in on-premises and cloud environments.
