NetApp NCSIE NS0-180 Questions & Answers

• Question 41:

  You are setting up a switchless 2-node cluster. You must ensure that it is set up correctly. Which two commands would you execute to complete this task? (Choose two.)

  onfigured true

  A. cluster ha modify ode ata

  B. not int modify luster modify true

  C. network options switchless

  D. net int create

  Correct Answer: AC

  Explanation: Enabling cluster HA and switchless-cluster in a two-node cluster If you have a two-node switchless configuration that uses direct-cable connections between the nodes instead of a cluster interconnect switch, you must ensure that the switchless-cluster- network option is enabled. This ensures proper cluster communication between the nodes.

  Stepscluster ha modify -configured true If storage failover is not already enabled, you will be prompted to confirm enabling of both storage failover and auto-giveback. set -privilege advanced Confirm when prompted to continue into advanced mode. The advanced mode prompt appears (*>). network options switchless-cluster show If the output shows that the value is false, you must issue the following command: network options switchless-cluster modify true set -privilege admin

• Question 42:

  Your customer received an HA pair of FAS8040 nodes with two half-populated disk shelves which they want to add to their cluster. When you arrive to add the nodes to their cluster, the customer informs you that they have 24 NSE drives that they want to use to fully populate two of the disk shelves.

  What should you do in this scenario?

  A. Change the boot variable bootarg.strorageencryption.support to false.

  B. Move all the NSE disks into one shelf and all the hard disks into the other shelf before you install the new HA pair.

  C. Inform your customer that they cannot mix NSE drives and regular hard disks in a storage system.

  D. Comply with your customers request, and add the NSE drives before you add the nodes and disk shelves to their cluster.

  Correct Answer: C

  Explanation: All disks in the storage system and optional attached disk shelves must have encryption functionality to be able to use Storage Encryption. You cannot mix regular non-encrypting disks with self-encrypting disks.

  Note: NetApp Storage Encryption (NSE) is NetApp's implementation of full-disk encryption (FDE) using

  self-encrypting drives from leading vendors.

• Question 43:

  According to NetApp best practices, which two sets of protocols would be assigned to the same storage virtual machine (SVM)? (Choose two.)

  A. FCP, NFS

  B. CIFS, iSCSI

  C. NFS. CIFS

  D. FCP, iSCSI

  Correct Answer: C

  Explanation: For Storage Virtual Machines (SVMs) that are accessible from multiple protocols, such as CIFS and NFS, you can use DNS load balancing and automatic LIF rebalancing simultaneously.

• Question 44:

  You are asked to install a cluster that consists of two FAS8060 controllers and four DS2246 shelves. The customer wants two stacks of shelves (10-11 and 20-21).

  According to NetApp, how many SAS cables are required to complete this installation with MPHA?

  A. 10 SAS cables

  B. 12 SAS cables

  C. 8 SAS cables

  D. 6 SAS cables

  Correct Answer: C

• Question 45:

  What is a protocol?

  A. SnapRestore

  B. CIFS

  C. SnapMirror/SnapVault

  D. FlexClone

  Correct Answer: B

  Explanation: The Common Internet File System (CIFS) is protocol which is the standard way that computer

  users share files across corporate intranets and the Internet.

  Incorrect:

  Not D: FlexClone is a technology to make fast, space-efficient copies of flexible volumes (FlexVol volumes)

  and LUNs.

• Question 46:

  Click the Exhibit button.

  

  Customer wants to modify the properties of their SPI Web services as shown in the exhibit. What is the reason for the error?

  A. The customer is trying to modify a service by specifying the wrong type of SVM (Vserver).

  B. The customer is trying to modify a service that does not exist.

  C. The customer is trying to modify a service by specifying the wrong service name.

  D. The customer is trying to modify a service by specifying incomplete parameters.

  Correct Answer: C

• Question 47:

  You will be performing a new cluster Data ONTAP 8.3 or later installation.

  Which three tools would you download to facilitate this task? (Choose three.)

  A. Config Advisor

  B. Cluster Config Builder

  C. OnCommand System Manager

  D. System Setup tool

  E. SLDIAG tool

  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.

• Question 48:

  You have completed the installation of a 4-node cluster. The customer did not purchase management switches and will not allow your laptop on the network.

  In this situation, what are two valid procedures that will allow you to collect the Config Advisor output? (Choose two.)

  A. Bring a switch that allows you to connect your laptop to all the switches and controllers.

  B. Connect to a single controller in the cluster since it can run commands on every node.

  C. Ask the customer to install and run Config Advisor on one of their PCs on the network.

  D. Connect four USB serial cables to your laptop to allow you to connect to all four controllers.

  Correct Answer: BC

• Question 49:

  You are adding nodes to an existing cluster.

  In this scenario, which three statements are correct? (Choose three.)

  A. If you are adding a second node to a single-node cluster, the second node must have been installed, but the cluster network can be configured later.

  B. You must add a cluster switch for every two nodes.

  C. If you are adding nodes to a multiple-node cluster, more than half of the existing nodes in the cluster must be healthy.

  D. The switchless cluster functionality is supported only in a single or two-node cluster.

  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.

  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.

• Question 50:

  What is s LIF?

  A. a logical internet file

  B. a logical inventory file

  C. a logical interaction file

  D. a logical interface

  Correct Answer: D

  Explanation: A LIF (logical interface) is an IP address or WWPN with associated characteristics, such as a role, a home port, a home node, a list of ports to fail over to, and a firewall policy. You can configure LIFs on ports over which the cluster sends and receives communications over the network.
