CV0-004 Practice Question: A cloud operations team uses a configuration…
A cloud operations team uses a configuration management tool to apply patches to hundreds of Linux servers. Recently, the automation script that applies security patches has been failing with an error: 'Package not found.' The administrator verifies that the patch repository URL is correct and that the servers have internet access. The script runs every Sunday at 2:00 AM and the failures started two weeks ago. The failed patches are all for the latest kernel update. What should the administrator check FIRST?
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
✓
Verify that the package cache is being updated before the installation step.
The error 'Package not found' typically indicates that the repository metadata is outdated. On many Linux systems, the local package cache (e.g., apt or yum) needs to be updated before installing new packages. The script likely needs to run an update command before attempting to install the patch.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Verify that the package cache is being updated before the installation step.
Why this is correct
The package cache must be refreshed to recognize the latest kernel package; the script may have skipped that step.
- ✗
Ensure the patch repository is reachable via DNS.
Why it's wrong here
The administrator already verified repository URL and internet access, so DNS is likely fine.
- ✗
Check if the servers have sufficient disk space for the patch download.
Why it's wrong here
Disk space would cause a different error, such as 'No space left on device'.
- ✗
Roll back to an earlier version of the patch script.
Why it's wrong here
Rolling back may reintroduce other issues; it's better to identify the missing step in the current script.
