Questions # 21:

You want to add two new nodes to an existing 4-node cluster.

In this situation, what must be considered regarding the cluster interconnect?

Options:

When a new node joins a cluster, IP addresses are generated automatically.

IP addresses are used from the data LIFs.

Customer IP addresses must be provided.

Class A subnet settings must be used.

Answer

Questions # 22:

You are deploying an 8-node AFF A700 using BES-53248 switches. Ports higher than 16 are not online.

Which two steps must be taken? (Choose two.)

Options:

Reload the firmware

Reload the RCF file

Re-enable each port

Reload the switch

Answer

B, C

Questions # 23:

You have added two new AFF A250 nodes to an existing 4-node cluster with NetApp CN1610 cluster network switches. Although the nodes can join the cluster, the storage failover show command output shows that the NVRAM log is not synchronized, and it cannot reach the partner over an HA interconnect.

In this scenario, which two statements are true? (Choose two.)

Options:

The AFF A250 requires switches with 40GbE port support.

The AFF A250 uses different ports for the cluster and the HA interconnect.

The AFF A250 requires switches with 25GbE port support.

The AFF A250 uses the same port for the cluster and the HA interconnect.

Answer

C, D

Explanation

AFF A250 systems use aconverged networking design, where the same physical ports are used for bothcluster interconnect traffic and HA interconnect traffic. This differs from older platforms that used dedicated HA interconnect ports.

The NetApp CN1610 switches only support10GbE, which is insufficient for AFF A250 systems. AFF A250 platforms require25GbE-capable cluster switchesto support both cluster and HA interconnect traffic.

Because the cluster ports are operational, the nodes can join the cluster. However, the HA interconnect traffic cannot be established due to insufficient switch capability, which explains why the NVRAM log cannot synchronize and the HA partner is unreachable.

Therefore:

The AFF A250requires switches with 25GbE port support

The AFF A250uses the same ports for cluster and HA interconnect

Statements involving 40GbE or separate HA ports are incorrect.

The correct answers areC and D.

Questions # 24:

After the successful installation of a NetApp ONTAP cluster, the customer wants to view telemetry data and receive online information about risks and best-practice gaps.

Which tool satisfies the customer’s requirements?

Options:

Active IQ Digital Advisor

Interoperability Matrix Tool

Spot by NetApp

Cloud Manager

Answer

Explanation

Active IQ Digital Advisor provides telemetry analysis, predictive risk detection, and best-practice recommendations based on AutoSupport data. It is specifically designed for proactive monitoring and risk mitigation.

Questions # 25:

After the installation of a new 2-node cluster, you want to ensure AutoSupport is working as expected.

Which two ways can you trigger a new AutoSupport? (Choose two.)

Options:

Use the ping command on the mailhost.

Use the OnCommand Unified Manager GUI.

Use the OnCommand System Manager GUI.

Use the system node autosupport invoke -type test command.

Answer

C, D

Explanation

AutoSupport can be manually triggered using the ONTAP CLI command or via System Manager. Ping tests and Unified Manager do not trigger AutoSupport generation.

Questions # 26:

What is the purpose of a mailbox disk?

Options:

Shipping defective drives

Storing HA partner information

Logging

Sending AutoSupport mail

Answer

Explanation

Mailbox disks store HA metadata and partner state information required for takeover and giveback operations.

Questions # 27:

You completed a 2-node AFF A700 installation according to the poster. You run the disk show -fields owner command and notice that all drives are assigned to node 1.

In this scenario, which tool would you use to access documentation and guidelines to solve the issue?

Options:

Active IQ Unified Manager

Active IQ One Collect

NET2

NetAppDocs

Answer

Explanation

NetAppDocsprovides official installation documentation, posters, and step-by-step guidelines. It is the correct resource for resolving disk ownership and installation workflow issues.

Questions # 28:

You want to add an AFF A400 HA pair to an existing cluster.

In this scenario, which LIF type is required?

Options:

cluster-mgmt

intercluster

data

node-mgmt

Answer

Explanation

When expanding an ONTAP cluster by adding new nodes or HA pairs,intercluster LIFsare required to enable secure communication between clusters or nodes during join and expansion workflows. Intercluster LIFs provide IP-based connectivity used for cluster peering, node addition, and replication setup.

Cluster management LIFs are used for administrative access, node management LIFs provide per-node management access, and data LIFs are used for client I/O. None of these LIF types support the inter-node communication required during cluster expansion.

Therefore, anintercluster LIFis required.

Questions # 29:

You are a NetApp Professional Services engineer. You have completed an ONTAP cluster installation and need to collect configuration information to enable creation of a Service Event Report (SER).

Which tool would you use?

Options:

Active IQ scheduled reports

NetAppDocs output report

ONTAP System Manager

Active IQ Config Advisor worksheet

Answer

Explanation

Service Event Reports require standardized installation and configuration data.NetAppDocsgenerates structured output reports specifically designed for SER creation, including hardware, cabling, and configuration details. Other tools do not produce SER-formatted documentation.

Questions # 30:

A customer is creating a new SVM to host iSCSI LUNs for a Hyper-V cluster. You need to successfully map the new LUNs and make them visible to the Hyper-V cluster.

In this scenario, which host information is required to accomplish this task?

Options:

IQNs

WWNNs

WWPNs

host names

Answer

Explanation

iSCSI usesIQNs (iSCSI Qualified Names)to identify initiators. When mapping LUNs for iSCSI access, ONTAP requires the initiator IQNs to create igroups and establish access control. WWNNs and WWPNs are used for Fibre Channel, not iSCSI.

Therefore, IQNs are required.
