NS0-157 · Question #272

Before establishing a CIFS share, which four steps must be taken? (Choose four.)

The correct answer is A. Mount a volume within a namespace B. Configure name mapping D. Create a volume E. Configure an export policy. Establishing a CIFS share in clustered ONTAP requires creating a volume, mounting it in the SVM namespace, configuring name mapping, and setting an export policy before the share itself is created.

Why each option

Establishing a CIFS share in clustered ONTAP requires creating a volume, mounting it in the SVM namespace, configuring name mapping, and setting an export policy before the share itself is created.

AMount a volume within a namespaceCorrect

Mounting the volume at a junction path within the SVM namespace is required so that the share path resolves correctly and clients can traverse the namespace to reach the data.

BConfigure name mappingCorrect

Name mapping must be configured to translate Windows domain user identities to UNIX UIDs, which ONTAP requires to enforce file permissions in a CIFS environment.

CConfigure a share policy with the desired values

Configuring a share policy with specific values is performed during or after share creation, not as a prerequisite step before the share exists.

DCreate a volumeCorrect

Creating the volume is a fundamental prerequisite because the CIFS share is simply an access point into a volume - without the volume there is no underlying storage to expose.

EConfigure an export policyCorrect

An export policy must be assigned to the volume to define which hosts or subnets are permitted to access it, as ONTAP enforces export policy rules for both CIFS and NFS protocol access.

FEnable Active Directory routing

Enabling Active Directory routing is not a recognized or required step - Active Directory integration is handled at the CIFS server (SVM) configuration level, not as a separate routing enablement.

GSet a default share policy

Setting a default share policy is not a prerequisite for share creation - ONTAP provides a built-in default share policy and it does not need to be explicitly set before establishing a share.
