A Windows VM and a Linux VM are both joined to the same Active Directory Domain Services domain. Which two authentication methods can be used to mount the same Azure Files share over SMB? Select two.
The storage account key can authenticate SMB mounts from supported Windows and Linux clients.
Why this answer
Option A is correct because the storage account key provides administrative access to the Azure Files share, allowing any SMB client (Windows or Linux) to mount the share by using the key as the credential. Option B is correct because when both VMs are joined to the same Active Directory Domain Services domain, the Azure Files share can be enabled for AD DS authentication, allowing domain-joined clients to mount the share using their domain credentials.
Exam trap
The trap here is that candidates often confuse Azure Files authentication with Blob Storage authentication, mistakenly selecting a SAS token as a valid method for SMB mounting, when in fact SAS tokens are only used for REST-based access to Blob or File storage (via HTTPS), not for SMB protocol.
