NS0-157 Question #381: Real Exam Question with Answer & Explanation

The correct answer is A: Mount the required volumes in a namespace. In NetApp ONTAP, volumes are made accessible to NAS clients by mounting them at junction points within the SVM namespace, allowing export policies to control access per volume.

Question

How do you organize volumes for data clients with an appropriate export policy?

Options

AMount the required volumes in a namespace
BMount the required namespaces in a volume
CMount the required namespaces in an aggregate
DMount directories of a volume in a namespace

Explanation

In NetApp ONTAP, volumes are made accessible to NAS clients by mounting them at junction points within the SVM namespace, allowing export policies to control access per volume.

Common mistakes.

B. The namespace is not an entity that gets mounted inside a volume - volumes are mounted into the namespace, not the reverse.
C. Aggregates are physical storage groupings and have no role in the logical namespace hierarchy; namespaces are associated with SVMs, not aggregates.
D. Directories within a volume are not individually junction-mounted into the namespace; entire volumes are mounted at junction points.
