CompTIA A+ Core 2 (220-1102) — Question 198

A systems administrator is creating periodic backups of a folder on a Microsoft Windows machine. The source data is very dynamic, and files are either added or deleted regularly. Which of the following utilities can be used to mirror the source data for the backup?

Answer options

• A. copy
• B. xcopy
• C. robocopy
• D. Copy-Item

Correct answer: C

Explanation

The correct answer is C, robocopy, as it is specifically designed for robust file copying and can mirror directories while handling changes such as file additions and deletions. Options A (copy) and B (xcopy) do not provide the same level of functionality for mirroring, and D (Copy-Item) is a PowerShell command that is not as efficient for large backups compared to robocopy.
