AZ-104 Certification Practice Question #128

Question

You have an Azure Storage account named storage1 that uses Azure Blob storage and Azure File storage.
You need to use AzCopy to copy data to the blob storage and file storage in storage1.
Which authentication method should you use for each type of storage? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

Accepted Answer

1. **Blob storage:** AzCopy has long supported both interactive/non-interactive Azure AD authentication (via `azcopy login`) and Shared Access Signatures (SAS) tokens to authorize data movement. Therefore, the combined option is correct.
2. **File storage:** In the design of Azure Files and older versions of AzCopy, SAS tokens were the only supported authorization mechanism for copying files/directories into file shares. While Microsoft has recently added Microsoft Entra ID support for Azure Files under specific preview/roles, the classic and correct answer for this AZ-104 exam question remains "Shared Access Signature (SAS) token only".
