ISC2 CC Practice Question: Business Continuity, Disaster Recovery, and Incident Response

A company performs a full backup every Sunday and incremental backups on other days. On Wednesday, a server failure occurs. Which backups are needed to restore the server to its state at Tuesday's backup?

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

✓

Sunday full backup, Monday incremental, and Tuesday incremental

With incremental backups, you need the last full backup and all subsequent incremental backups up to the point of failure. Here, Sunday full + Monday incremental + Tuesday incremental.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Only Tuesday incremental backup

    Why it's wrong here

    Incremental backups alone cannot restore without a full base.

  • ✓

    Sunday full backup, Monday incremental, and Tuesday incremental

    Why this is correct

    Incremental restores require full plus all incrementals since the full.

  • ✗

    Only the Sunday full backup

    Why it's wrong here

    The full backup alone would not include changes from Monday and Tuesday.

  • ✗

    Sunday full backup and Monday incremental backup

    Why it's wrong here

    Missing Tuesday incremental backup.
