Questions # 31:

A customer wants to graphically manage a new clustered Data ONTAP system.

Which tool should the customer use?

Options:

System Setup

OnCommand System Manager

HostAgent

StorageGRID

Answer

Explanation

Graphical management of clustered Data ONTAP systems is performed usingOnCommand System Manager, which provides a web-based interface for configuration, monitoring, and administration.

System Setup is used only for initial node setup, HostAgent is host-side software, and StorageGRID is an object storage platform unrelated to ONTAP cluster management.

OnCommand System Manager allows administrators to manage aggregates, volumes, LIFs, SAN objects, and system health through an intuitive GUI, making it the correct choice.

Therefore, the correct answer isB, as defined byNetApp.

Questions # 32:

Your customer plans to expand a 2-node FAS2750 switched cluster with two new controllers.

In this scenario, which two prerequisites should you examine in advance? (Choose two.)

Options:

Verify that the hard drives of the new controllers are compatible with the old controllers.

Verify that the existing cluster has a minimum 10 GB of free space for root volumes.

Verify that the existing switches support the additional controllers.

Verify that the platform of the new controllers can be mixed with the cluster’s existing controllers.

Answer

C, D

Questions # 33:

Where is user data (file access) written to by default?

Options:

Aggr0_root

Vol0_root

mailbox disks

SVM volume

Answer

Explanation

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.

Questions # 34:

You are installing a new six-node ONTAP 9.8 cluster. You have completed the initial configuration of the cluster interconnect switches and the ONTAP cluster.

In this scenario, which feature should you enable?

Options:

cluster switch logging

cluster switch health monitor

IPv6 on all cluster ports

data center bridging protocol

Answer

Explanation

After completing the initial configuration of a multi-node ONTAP cluster and its cluster interconnect switches, NetApp installation best practices require enabling proactive monitoring of the cluster network. TheCluster Switch Health Monitor (CSHM)is the ONTAP feature designed specifically for this purpose.

CSHM continuously monitors the health of supported cluster switches by collecting information such as switch configuration, port status, firmware versions, cabling, and error conditions. It validates this information against NetApp-supported configurations and best practices. When deviations or risks are detected, CSHM generates alerts and EMS messages that allow administrators to take corrective action before cluster communication is affected.

Cluster switch logging alone does not provide health analysis or proactive validation; it only records switch events. IPv6 is not required or recommended for cluster interconnect networks in standard ONTAP installations. Data Center Bridging (DCB) is used for specific Ethernet storage protocols and is not applicable to ONTAP cluster interconnect networks.

Therefore, enabling thecluster switch health monitoris the correct and required post-installation step.

Questions # 35:

You are attempting to add a new ONTAP 9.7 node to your ONTAP 9.8 NetApp cluster. After attempting to add the node, the operation fails as shown in the exhibit.

Question # 35

What are two nondisruptive ways to add the new node to your ONTAP cluster? (Choose two.)

Options:

Revert the cluster from ONTAP 9.8 to ONTAP 9.7.

Re-initialize all the nodes in the ONTAP cluster with ONTAP 9.7.

Upgrade the new node from ONTAP 9.7 to ONTAP 9.8.

Add the node using the -allow-mixed-version-join parameter.

Answer

C, D

Explanation

ONTAP clusters require that all nodes run the same ONTAP version before a node can join the cluster under normal conditions. The exhibit clearly indicates that the join operation failed because the cluster is running ONTAP 9.8 while the new node is running ONTAP 9.7, resulting in a mixed-version cluster restriction.

One nondisruptive solution is toupgrade the new node to ONTAP 9.8before attempting to join it to the cluster. This approach aligns the software version of the new node with the existing cluster and fully complies with NetApp-supported installation procedures. It does not impact cluster availability and is the preferred long-term solution.

The second nondisruptive option is to use the-allow-mixed-version-joinparameter. ONTAP explicitly allows this method to temporarily permit a mixed-version cluster for the purpose of expansion or upgrade workflows. This option is designed for controlled scenarios and allows the node to join without disrupting existing cluster operations. However, the mixed-version state is intended to be temporary and must be resolved by upgrading the remaining nodes.

Reverting the cluster or reinitializing all nodes would be disruptive and violate nondisruptive installation principles. Therefore, the correct answers areC and D.

Questions # 36:

You are preparing for the installation of a new 2-node switchless AFF A250 ONTAP 9.8 cluster and need to obtain the preinstallation information from the customer.

In this scenario, what are three examples of data required from the customer? (Choose three.)

Options:

management IP addresses

cluster switch name

gateway IP address

BMC IP addresses

cluster name

Answer

A, C, D

Explanation

Preinstallation planning requires collecting network and management information necessary for initial configuration. For a switchless cluster, cluster switch information is not applicable.

Required data includesmanagement IP addressesfor cluster and node management access,gateway IP addressesfor external connectivity, andBMC IP addressesfor out-of-band hardware management.

Cluster names are typically assigned during setup but are not strictly required as preinstallation inputs from the customer.

Therefore, the correct answers areA, C, and D.
