NS0-157 · Question #22

You have multiple volumes that are exported to a group of hosts within your environment. A new host needs access to the volumes. Which two actions accomplish this task? (Choose two.)

The correct answer is C. Create a rule in the export policy on the SVM. D. Create a new data LIF on the SVM. Granting a new host access to existing ONTAP NFS/CIFS volumes requires both a network-level connection via a data LIF and a storage-level permission via an export policy rule.

Why each option

Granting a new host access to existing ONTAP NFS/CIFS volumes requires both a network-level connection via a data LIF and a storage-level permission via an export policy rule.

AMount the new export s from the host.

Mounting exports is a client-side operation performed on the host after access is configured on the SVM; it does not provision permissions or network paths on the ONTAP side.

BCreate a new SVM.

Creating a new SVM is not required because the existing SVM already owns the volumes and export policies; new host access is configured within the existing SVM, not by adding another one.

CCreate a rule in the export policy on the SVM.Correct

Export policy rules define which client IPs or subnets are authorized to mount volumes; without a matching rule for the new host, ONTAP denies access at the protocol layer regardless of network reachability.

DCreate a new data LIF on the SVM.Correct

A data LIF is the IP endpoint the new host uses to connect to the SVM for file services; if the host resides on a network segment not already served by an existing LIF, a new data LIF must be created to provide connectivity.
