NS0-180 Online Practice Questions and Answers

Correct Answer: D

Explanation: You re-create the cluster using the cluster configuration that you chose and made available to the recovering node, and then rejoin each additional node to the new cluster.

You should only perform this task to recover from a disaster that resulted in the loss of the cluster's configuration.

Steps

1.

On the recovering node, use the system configuration recovery cluster recreate command at the advanced privilege level to re-create the cluster.

2.

Use the cluster identity show command to verify that the recovering node has a different UUID than the other nodes.

3.

For each node that needs to be joined to the re-created cluster, do the following: 3a. From a healthy node on the re-created cluster, use the system configuration recovery cluster rejoin command at the advanced privilege level to rejoin the target node to the cluster. Example This example rejoins the target node (node2) to the re-created cluster. cluster1::*> system configuration recovery cluster rejoin -node node2

Warning: This command will rejoin node "node2" into the local cluster, potentially overwriting critical cluster

configuration files. This command should only be used to recover from a disaster. Do not perform any other

recovery operations while this operation is in progress.

This command will cause node "node2" to reboot.

Do you want to continue? {y|n}: y

The target node reboots and then joins the cluster.

3b. Use the cluster show command with the -eligibility parameter to verify that the target node is healthy

and has formed quorum with the rest of the nodes in the cluster. The target node must rejoin the re-created

cluster before you can rejoin another node.

Correct Answer: A

Explanation: IPspaces enable you to configure a single Data ONTAP cluster so that it can be accessed by clients from more than one administratively separate network domain, even if those clients are using the same IP address subnet range

Reference: Clustered Data ONTAP 8.3, Network Management Guide, page 32

Correct Answer: BCE

Explanation: C: If you are adding nodes to a multiple-node cluster, more than half of the existing nodes in the cluster must be healthy (indicated by cluster show).

E: If you are adding nodes to a two-node switchless cluster, you must have installed and configured the

cluster management and interconnect switches before adding additional nodes.

Incorrect:

not A: If you are adding a second node to a single-node cluster, the second node must be installed, and the

cluster network must be configured. Not D: The switchless cluster functionality is supported only in a two-

node cluster.

Correct Answer: BC

Correct Answer: ACD

Explanation: D: After installing the hardware, you should use System Setup whenever possible to set up the cluster.

C: After setting up the cluster, you can use either OnCommand System Manager or the Data ONTAP CLI to continue configuring the cluster.

A: You can go to the NetApp Support Site and download the Config Advisor tool to check for common configuration errors.

Correct Answer: D

Correct Answer: BC

Explanation: Cisco NX5596 is a cluster interconnect switch. NetApp CN1610 is a cluster interconnect switch that can be used for FAS8040 nodes.

Incorrect:

Not A: The Cisco Catalyst 2960 is not a cluster interconnect switch. Not D: NetApp CN1601 is a cluster

management switch.

Correct Answer: AB

Explanation: A: Check that the mail host specified in the options is a host that the storage system can talk

to, by running the following command on the storage system:

ping mailhost_name

mailhost_name is the name of the mail host specified in the AutoSupport options.

B: The customer firewall must let SMTP (port 25) messages go through their firewall.

Correct Answer: A

Note: The following conditions must exist before installing the FASTPATH software and reference configuration file (RCF) on a NetApp CN16xx cluster switch:

* The cluster must be a fully functioning cluster. Etc.

Correct Answer: C

Explanation: Example of appropriate name: n01sas01

Underscores can be used, but not "." or "-".

Note: Aggregate names must conform to the following requirements:

They must begin with either a letter or an underscore (_). They can contain only letters, digits, and

underscores.

They must contain 250 or fewer characters.

Correct Answer: B

Explanation: The NetApp Interoperability Matrix defines infrastructure components and versions that can be

used for configurations that NetApp corporation support end to end.

Incorrect:

Not C: Inventory Collect Tool enables you to create an inventory report that contains information about 7Mode storage systems, hosts, and host applications. The inventory report can then be imported to the 7Mode Transition Tool for transition assessment.

Correct Answer: C

Explanation: We need to add a partner statement to the /etc/rc file on node-2.

Correct Answer: B

Explanation: Data ONTAP services may initiate network connections from a node in the cluster. For example: AutoSupport, SNMP, time synchronization, and syslog. When a Node Management interface is configured and available, it is preferred for these connections. When Data ONTAP contacts name services like Active Directory, NIS, DNS, or LDAP, it prefers to initiate these connections from Data or SVM Management interfaces belonging to the Storage Virtual Machine (SVM). Note: A LIF role determines the kind of traffic that is supported over the LIF, along with the failover rules that apply and the firewall restrictions that are in place. The five LIF roles are:

*

Cluster-management LIF

*

Node-management LIF

*

Cluster LIF

*

Data LIF

*

Intercluster LIF

Correct Answer: B

Explanation: The following conditions must exist before installing the FASTPATH software and reference configuration file (RCF) on a NetApp CN16xx cluster switch:

*

The cluster must be a fully functioning cluster.

*

There must be no defective cluster NICs and all connected ports on both cluster switches must be

functional.

*All cluster ports must be up.

*

All cluster logical interfaces (LIFs) must be up and must not have been migrated.

*

The Data ONTAP (privilege: advanced) cluster ping-cluster -node node1 command must indicate that

larger than PMTU communication is successful on all paths.

*

You must consult the switch compatibility table on the NetApp CN1601 and CN1610 Switches page for

the supported FASTPATH, RCF, and Data ONTAP versions. T
