Question 12 - NetApp NS0-175 Real Exam Questions [Feb 2026 Update]

Q: 12

A customer has decided to deploy Red Hat OpenShift on a FlexPod solution, based in a published Cisco Validated Design. The customer intends to use the NetApp Trident to attach persistent storage to the customer’s containers from the customer’s NetApp AFF controllers. In this scenario, which two storage protocols are supported? (Choose two.)

Options

Correct Answer:

A, C

Explanation

NetApp Trident serves as a storage orchestrator for container platforms like Red Hat OpenShift, provisioning storage from NetApp backends. When using an ONTAP-based system such as an AFF controller, Trident utilizes specific drivers to provide persistent volumes. The ontap-nas and ontap-nas-economy drivers provision file-based storage using the NFS protocol. For block-based storage, the ontap-san and ontap-san-economy drivers provision LUNs and connect them to container hosts using the iSCSI protocol. Therefore, in this FlexPod and OpenShift context, NFS and iSCSI are the two supported protocols for persistent storage via Trident.

Why Incorrect

B. FC: Trident's ontap-san driver for ONTAP systems does not support the Fibre Channel (FC) protocol for dynamic provisioning of persistent volumes.

D. SMB: The Trident ontap-nas driver, which provides file-based persistent volumes from ONTAP systems, exclusively uses the NFS protocol. It does not support SMB/CIFS for this purpose.

References

1. NetApp Trident Documentation, "Backend configuration": This official documentation details the drivers available for different NetApp storage backends. For ONTAP, it explicitly lists the ontap-nas driver using NFS and the ontap-san driver using iSCSI.

Reference: NetApp, "Trident Documentation > Set up > Backend configuration > ONTAP configuration". Section: "ONTAP SAN drivers (ontap-san, ontap-san-economy)" states, "These drivers create iSCSI LUNs..." and Section: "ONTAP NAS drivers (ontap-nas, ontap-nas-economy)" states, "These drivers create ONTAP FlexVols and share them via NFS..."

2. Cisco Validated Design (CVD), "FlexPod Datacenter with Red Hat OpenShift Container Platform 4.6 Design Guide": This guide provides a validated architecture for the scenario described. In the storage configuration sections, it demonstrates the creation of Trident backends and Kubernetes StorageClasses using only the ontap-nas (NFS) and ontap-san (iSCSI) drivers.

Reference: Cisco Validated Design CVD-1594, "Chapter 4: FlexPod Datacenter with Red Hat OpenShift Container Platform 4.6 Design". Section: "Storage for OpenShift Container Platform > NetApp Trident Storage Orchestrator for Kubernetes", Figures 36 and 37 show backend configurations for ontap-nas and ontap-san, which map to NFS and iSCSI respectively.
