Introduction to CIFS in Clustered Data ONTAP

Your Windows clients were able to access the CIFS SVM yesterday. Today, they can no longer access the CIFS SVM on your NetApp cluster. Your IT security team has just deployed a new group policy to improve security.

In this scenario, which statement is true?

  • A Your CIFS SVM is not using DNS.
  • B Your CIFS SVM is configured to use SMBv1 and SMBv2.
  • C Your CIFS SVM is configured for NFSv3 access.
  • D Your CIFS SVM is configured for the wrong domain.
Explanation

Windows SMB access should use DNS-based name resolution: ONTAP requires DNS records that map the SMB server name and aliases to the data LIF, and Windows direct-hosted SMB standardizes file-sharing name resolution on DNS instead of the less secure NetBIOS mechanism. A security policy that disables or restricts NetBIOS can consequently expose an SMB server that is not using DNS.
