CV0-002 · Question #249

A customer wants a cloud systems administrator to adjust the backup schedule after month-end to ensure the data can be restored as fast as possible while minimizing the time needed to perform the back

The correct answer is A. Synthetic full. To achieve fast data restoration and minimize backup time for month-end operations, a synthetic full backup is the most appropriate choice.

Why each option

To achieve fast data restoration and minimize backup time for month-end operations, a synthetic full backup is the most appropriate choice.

ASynthetic fullCorrect

A synthetic full backup combines an initial full backup with subsequent incremental backups on the backup server itself to create an updated full backup image, allowing for single-step, fast restorations while only requiring changed data to be transmitted during ongoing backups, minimizing backup time.

BIncremental

Incremental backups are fast to perform but can be slow and complex to restore, requiring the original full backup and all subsequent incremental backups to be applied sequentially.

CDifferential

Differential backups are faster to restore than incremental ones but take longer to perform than incrementals as they back up all changes since the last full backup, accumulating data over time.

DFull

Full backups offer the fastest restoration (a single backup set) but consume the most time and resources during the backup process as they copy all selected data every time.
