CISA Practice Question: Refer to the exhibit

Exhibit

Refer to the exhibit.

```
Error Log Entry:
Timestamp: 2024-03-20 10:15:32
Source: BackupServer01
EventID: 213
Level: Error
Message: Backup job 'DailyBackup' failed. Source volume: \\FileServer\Shares, Destination: \\BackupServer01\Backup\Shares. Error code: 0x80070002 (The system cannot find the file specified.)
```

Refer to the exhibit. An IS auditor is reviewing backup error logs. The error indicates a failed backup due to a missing file. What is the MOST likely cause?

⚠ Common exam trap

It's easy for candidates to confuse a 'missing file' error with a destination path issue or resource constraint, but the error message specifically points to a source-side file inconsistency, not a connectivity or capacity problem.

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

✓

A file in the source volume was moved or deleted during the backup window

The error indicates a failed backup due to a missing file. The most likely cause is that a file in the source volume was moved or deleted during the backup window. Backup processes that use file-level snapshots or open-file managers (e.g., Volume Shadow Copy Service on Windows) capture a point-in-time view; if a file is moved or deleted after the snapshot is taken but before it is read by the backup agent, the backup will fail with a 'missing file' error. This is a classic race condition in file-level backups without proper snapshot consistency.

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 backup job was scheduled during peak hours causing timeout

    Why it's wrong here

    Timeout errors are different (e.g., 0x80070005).

  • ✗

    The destination path '\\BackupServer01\Backup\Shares' is invalid

    Why it's wrong here

    The destination path appears valid; the error is about a file not found.

  • ✓

    A file in the source volume was moved or deleted during the backup window

    Why this is correct

    File not found during backup is common when files change.

  • ✗

    Insufficient disk space on the backup destination

    Why it's wrong here

    Disk full errors have different codes (e.g., 0x80070070).
