Answer: D

Explanation:

According to Encryption-Files | Nutanix Community1, SMB3 message encryption is a feature that encrypts messages on the file server side and decrypts them on the client side. However, clients that do not support encryption (Linux, Mac, windows 7) cannot access a share with encryption enabled.

According to Nutanix Support & Insights2, Nutanix Files supports SMB3 encryption for SMB3 client-server traffic. This means that only clients that support SMB3 protocol can access encrypted shares.

Therefore, if the users are accessing the shares from Linux desktops, they will not be able to access them because Linux does not support SMB3 encryption.
