EX188 Registry And Security Practice Question
Which THREE actions occur when an administrator runs a container with an SELinux volume mount suffix ':Z'? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The host path's SELinux context is altered to match the container's private category.
The ':Z' suffix labels the content with a private SELinux context, modifies the host file context if necessary, and ensures isolation from other containers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The host path's SELinux context is altered to match the container's private category.
Why this is correct
Podman automatically applies the relabeling directly to the host files/directories.
- ✗
The SELinux enforcement mode on the host is temporarily set to permissive.
Why it's wrong here
SELinux enforcement mode on the host remains unchanged.
- ✓
The mounted content is labeled with a private, unshared SELinux security context.
Why this is correct
The :Z flag assigns a private label (e.g. multi-category security context) to the volume.
- ✗
The host directory becomes completely read-only across all namespaces.
Why it's wrong here
The :Z suffix does not make a mount read-only (that is :ro).
- ✓
Only the specific container launched with the flag can access the labeled files under SELinux enforcement.
Why this is correct
Private labeling restricts access exclusively to that container instance.
