An export policy can determine access to volumes for which of the following protocols?
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.

Why each option
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.
iSCSI and FC are SAN block protocols that use igroups and LUN masking for access control, not export policies.
Export policies are a NAS access-control mechanism that define which clients can access volumes via NFS and CIFS, using rules based on client IP, security style, and protocol. SAN protocols like iSCSI and FC use LUN masking and igroups for access control instead, making them outside the scope of export policies. Only NAS-connected volumes require export policy assignment.
iSCSI is a SAN protocol and is not governed by export policies, so including it makes this choice incorrect.
NFS is correct, but CIFS is also governed by export policies, so limiting the answer to NFS only is incomplete.
CIFS is correct, but NFS is equally governed by export policies, so limiting the answer to CIFS only is incomplete.
