XK0-006 Practice Question: The system is a web server running Apache and…
Exhibit
Refer to the exhibit. Filesystem Size Used Avail Use% Mounted on /dev/sda2 50G 50G 0 100% /
The system is a web server running Apache and MySQL. Based on the exhibit, which of the following is the most likely cause of the full disk?
⚠ Common exam trap
CompTIA often tests the candidate's ability to distinguish between common disk-filling causes (logs, databases, user files) by presenting a scenario where the exhibit shows a specific directory (like /var/log) as full, leading candidates to overlook the log rotation misconfiguration and instead blame MySQL or user home directories.
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
✓
Apache access and error logs are growing unchecked
Apache access and error logs are a common cause of full disks on web servers because they can grow unchecked, consuming all available space. By default, Apache logs are stored in /var/log/httpd/ or /var/log/apache2/ and are not rotated unless logrotate is configured. The exhibit likely shows a high percentage of disk usage in /var/log, confirming that log files are the culprit.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Home is often a separate partition or less likely.
- ✓
Apache access and error logs are growing unchecked
Why this is correct
Correct: Web server logs commonly fill root partitions.
- ✗
The /tmp directory is not being cleaned
Why it's wrong here
Less likely to use 50GB.
- ✗
The MySQL database has grown too large
Why it's wrong here
Possible, but logs are more common for rapid filling.
