CompTIA Server+ SK0-005 Practice Question

The correct answer is that the disk partition is full. A full disk partition explains both reported symptoms simultaneously. The database application cannot write new transaction logs or data, causing it to slow down and time out. Concurrently, users are unable to write new files to the share because there is no available space on the volume. A misconfigured RAID or a failed cache battery would likely cause performance degradation but not necessarily prevent all file writes, and the scenario states the RAID utility reports a healthy state. Incorrect file permissions would explain the inability to upload files but would not explain the database performance issues.
