Use Azure Storage Explorer’s graphical interface to drag-and-drop files
- D

Show answer and explanation
Correct answer: A
Explanation
AzCopy is designed for large-scale, automated data transfers to Azure Storage. It supports command-line scripting, offers resume capabilities, and handles large volumes of data more reliably than manual or GUI-based methods.
- A. Correct.
AzCopy supports large-scale, scriptable transfers, provides resume functionality for interrupted uploads, and is well suited for automating regular data migrations.
- B. Incorrect.
The Azure portal upload feature requires actively maintaining the browser session and lacks advanced functionalities like resume for very large transfers.
- C. Incorrect.
While Storage Explorer can handle smaller or occasional uploads, it does not provide robust command-line automation or efficient resume capabilities for extremely large data sets.
- D. Incorrect.
Mapping a drive to Azure Files can simplify manual copies but is less efficient for very large or frequently updated data and does not offer streamlined resume features.
