220-1102 Question #354: Real Exam Question with Answer & Explanation

Question

A company is looking for a solution that provides a backup for all data on the system while providing the lowest impact to the network. Which of the following backup types will the company MOST likely select?

Options

• AOff-site
• BSynthetic
• CFull
• DDifferential

Explanation

For a company seeking to back up all system data with the lowest network impact, a differential backup offers a balance between comprehensive restoration capability and reduced data transfer compared to a full backup.

Common mistakes.

• A. Off-site refers to the location of the backup storage, not the type of backup or its network impact.
• B. Synthetic backups create a new full backup from an existing full and subsequent incrementals/differentials, which can still involve significant processing and transfer depending on implementation.
• C. A full backup copies all selected data every time it runs, which typically has the highest network impact compared to differential or incremental backups.
