HP0-J67 · Question #33

An enterprise company needs the fastest deduplication technology for both backup and restore. Which technology should the company implement?

The correct answer is B. object-level differencing. Object-level differencing provides the fastest deduplication for both backup and restore by only storing changes between data objects, minimizing processing overhead and accelerating recovery.

Why each option

Object-level differencing provides the fastest deduplication for both backup and restore by only storing changes between data objects, minimizing processing overhead and accelerating recovery.

Ahash-based chunking

Hash-based chunking involves computing hashes for data segments, which is computationally more intensive than simply tracking changes at the object level for the fastest deduplication.

Bobject-level differencingCorrect

Object-level differencing, often implemented as block-level differencing, efficiently identifies and stores only the modified data blocks between backup versions, significantly speeding up both the backup process by reducing data transfer and the restore process by only applying deltas.

Capplication-based cloning

Application-based cloning creates full copies of data, which is not a deduplication technology aimed at reducing storage footprint.

Dhost-based file swapping

Host-based file swapping is not a recognized data deduplication or backup technology.
