A cloud administrator receives an alert that a virtual machine's disk usage is at 95%. The VM hosts a database. Which of the following troubleshooting steps should the administrator take FIRST?
⚠ Common exam trap
Many exam-takers assume high disk usage is always caused by temporary files or transactions, leading them to reboot or query the database first, rather than performing a simple disk space analysis to identify the actual culprit.

Correct answer & explanation
✓
Check the disk to identify which files are consuming space
When a VM's disk usage reaches 95%, the first step is to identify what is consuming the space. Checking the disk to identify which files are consuming space (Option D) allows the administrator to determine whether the issue is caused by database logs, temporary files, or other data, and to plan an appropriate remediation without unnecessary risk or downtime.

Expand the virtual disk by resizing the volume in the cloud console
