NS0-185 Exam Dumps - NetApp Storage Installation Engineer - ONTAP Professional Exam

Broadcom BES-53248 cluster interconnect switches require aReference Configuration File (RCF)to define supported port roles, speeds, breakout behavior, ISLs, and node-facing ports. By default, only a subset of ports is enabled for cluster connectivity. Ports0/17 through 0/20are not active for node connections unless explicitly configured by the correct RCF.

When new controllers are cabled to ports that are not enabled or correctly configured for cluster interconnect traffic, the ONTAP nodes cannot establish cluster LIF communication and therefore cannot join the cluster. Installing the correctRCFconfigures these ports with the required VLANs, MTU, flow control, and speed settings so that cluster traffic can pass.

A license file is not required for basic cluster interconnect functionality. The Cluster Switch Health Monitor (CSHM) configuration file enables monitoring, not port functionality. Rebooting controllers does not resolve switch-side configuration issues.

Therefore, installing thereference configuration fileis the required corrective action.

User data in ONTAP is written tovolumes owned by Storage Virtual Machines (SVMs). Root aggregates and root volumes are reserved for system metadata and ONTAP operations. Mailbox disks store HA metadata only.

Therefore, user data is written to anSVM volume.

AFF systems are all-flash platforms that rely heavily onsoftware-based efficiency technologiesbuilt into ONTAP. Two such technologies areFlexClone volumesandthin provisioning.

FlexCloneenables instant, space-efficient copies of volumes or files without duplicating data blocks. This is especially useful for testing, development, backups, and rapid provisioning scenarios. On AFF systems, FlexClone operations are nearly instantaneous and incur minimal overhead.

Thin provisioningallows logical storage to be allocated without immediately consuming physical capacity. This ensures maximum utilization of flash storage and prevents over-provisioning, which is critical in all-flash environments.

Flash Pool and FlashCache are hybrid-storage technologies and are not applicable to AFF A400 systems, which do not use HDDs or PCIe read-cache modules.

Therefore, the correct answers areB and D.

NS224 shelves are Ethernet-attached and connect through supported Ethernet switches. Additional capacity can be added either by attaching new NS224 shelves to the existing Ethernet fabric or by scaling out the cluster with additional AFF A400 nodes. NS224 shelves cannot be daisy-chained directly to other NS224 shelves, and dedicated storage switches are not required.

Using breakout cables disables paired ports on the same ASIC. This is expected behavior.

Physical installation of an AFF system requires specific tools. APhillips #2 screwdriveris required for securing rails and components. Alaptop computeris needed for console access, initial configuration, and validation. Acable management trayis necessary to properly route and secure cables, ensuring airflow and serviceability.

Additional network cables and slide rail kits are equipment components, not tools.

Therefore, the correct answers areB, C, and E.
