EX200 Practice Test 9 — 10 Questions

Question 1

A containerized application requires persistent storage and must be able to run with SELinux enforcing. The administrator runs a container with the volume mount: `podman run -v /host/data:/container/data:Z myimage`. Which TWO statements are true about this configuration?

Accepted Answer

The volume mount persists after the container is removed.. Option C is correct because the `-v` flag with a bind mount persists the data in `/host/data` on the host filesystem even after the container is removed. The `:Z` flag tells Podman to relabel the host directory with a container-specific SELinux context, which is why Option E is also correct. This ensures the container can write to the mount point even when SELinux is enforcing.

Answer

The SELinux context of files in /host/data remains unchanged.

Answer

The /host/data directory is created automatically if it does not exist.

Answer

The container cannot write to /container/data if SELinux is enforcing.

Question 2

Match each systemd unit type to its purpose.

Question 3

Match each SELinux mode to its behavior.

Question 4

Match each package management command to its action.

Question 5

Match each command to its function in managing storage.

Question 6

Match each firewall zone to its default trust level.

Question 7

Match each user/group management command to its function.

Question 8

Match each log file to its typical content.

Question 9

Refer to the exhibit. An administrator runs 'mount -o remount,ro /data' and then 'mount' shows /data as read-only. Later, the system is rebooted. What is the state of /data after reboot?

Accepted Answer

/data will be mounted read-write because fstab specifies defaults (rw).

Answer

/data will be mounted read-only because the remount persists across reboots.

Answer

/data will not be mounted because the filesystem is marked as read-only.

Answer

/data will be mounted read-only because the kernel remembers the last mount state.

Question 10

Refer to the exhibit. An administrator attempts to mount the partition but receives an error. Which command should be run first to resolve the issue?

Accepted Answer

file -s /dev/sdc1

Answer

xfs_repair /dev/sdc1

Answer

partprobe /dev/sdc

Answer

mkfs.xfs /dev/sdc1
