Which of the following statements is true about export policies?

The correct answer is B. Each data volume can only have one assigned export policy. In clustered Data ONTAP, each volume can have exactly one export policy assigned to it at any given time, though a single export policy can contain multiple export rules.

Why each option

In clustered Data ONTAP, each volume can have exactly one export policy assigned to it at any given time, though a single export policy can contain multiple export rules.

AEach data vserver can only have one assigned export policy

A data Vserver can have multiple export policies assigned across its various volumes; only individual volumes are limited to one policy each.

BEach data volume can only have one assigned export policyCorrect

Each data volume in an SVM has a single export policy assigned that controls all NAS client access to that volume. Multiple export rules can exist within that one policy to handle different client groups or access levels, but only one policy object is bound to a volume at a time. This design simplifies access management while still allowing granular rule-based control.

CEach data volume can only have one assigned export rule

A single export policy can contain multiple export rules, so the restriction of 'one rule per volume' is inaccurate.

DAccess to a volume is determined by the export policies created within an export rule

This reverses the relationship - access to a volume is determined by the export rules that exist within the export policy assigned to the volume, not the other way around.
