The correct answer is B: CIFS and NFS volumes. Export policies in clustered Data ONTAP govern access control for NAS protocols only - specifically CIFS and NFS - and do not apply to SAN block protocols.
Network Configuration and Data Access
Question
An export policy can determine access to volumes for which of the following protocols?
Options
- AiSCSI and FC volumes
- BCIFS and NFS volumes
- CiSCSI, CIFS, NFS
- DNFS volumes only
- ECIFS volumes only
Explanation
Export policies in clustered Data ONTAP govern access control for NAS protocols only - specifically CIFS and NFS - and do not apply to SAN block protocols.
Common mistakes.
- A. iSCSI and FC are SAN block protocols that use igroups and LUN masking for access control, not export policies.
- C. iSCSI is a SAN protocol and is not governed by export policies, so including it makes this choice incorrect.
- D. NFS is correct, but CIFS is also governed by export policies, so limiting the answer to NFS only is incomplete.
- E. CIFS is correct, but NFS is equally governed by export policies, so limiting the answer to CIFS only is incomplete.
Concept tested. Export policy scope across NAS protocols
