SSCP Practice Question: A company's backup strategy includes weekly full…
A company's backup strategy includes weekly full backups and daily differential backups. A ransomware attack occurred on Wednesday, corrupting data. The last full backup was Sunday. Which backup set should be restored first?
⚠ Common exam trap
Many candidates confuse differential backups with incremental backups, mistakenly thinking they need to restore all differentials in order, or they try to restore the most recent differential without the full backup first.
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
The correct restoration order is to first restore the Sunday full backup, because differential backups contain all changes since the last full backup. Without the full backup as a base, the differential backups cannot be applied. After restoring the full backup, you would then apply the most recent differential backup (Wednesday) to bring the data to the point just before the attack.
