NetApp NCSIE NS0-180 Questions & Answers

• Question 11:

  Click the Exhibit button.

  

  A customer has a 4-node cluster and wants to know what will happen to their data if one of the two HA pairs goes down. Epsilon is configured and working properly and is owned by Node1. Nodes 3 and 4 have failed as shown in the exhibit.

  What happens to the customer's data that is owned by the HA pair 3 and 4?

  A. Nodes 1 and 2 will takeover the storage for nodes 3 and 4 and continue running normally.

  B. The cluster will go into maintenance mode and only allow administrators access to data on nodes 1 and

  2.

  C. The entire cluster will panic and no data will be accessible.

  D. The customer will lose access to the data on nodes 3 and 4 but will still have access to storage in nodes 1 and 2.

  Correct Answer: A

  Explanation: An HA pair is two storage systems (nodes) whose controllers are connected to each other directly. In this configuration, one node can take over its partner's storage to provide continued data service if the partner goes down.

• Question 13:

  Your customer has four disk shelves attached to an HA pair of nodes running clustered Data ONTAP 8.3. One disk shelf has six SSDs and 18 HDDs installed. They want to know how to partition the SSDs to use them in a flash pool aggregate.

  In this situation, what should you tell the customer?

  A. Flash pool aggregates must have whole SSDs assigned, not partitions.

  B. When the disks are assigned to a storage pool, they are automatically partitioned into four equal parts that can be assigned to an existing aggregate where the partition will be used as flash storage by the assigned aggregate.

  C. All SSDs in a mixed disk system are partitioned to a 25% and a 75% partition. The larger partition can be used for data.

  D. When the disks are assigned to a storage pool, you can partition each disk into as many partitions as needed. A partition can be assigned to an existing aggregate where the partition will be used as a flash storage by the assigned aggregate.

  Correct Answer: B

  Explanation: Advanced drive partitioning for Flash Pool segments each drive into four pieces.

• Question 14:

  The full boot cycle of the CN1610 should take approximately 50 seconds.

  What should you do to minimize the interruption?

  A. Remove all of the cables from the CN1610 CL1 switch, and then connect them to different ports on the CN1610 CL2 switch.

  B. You can migrate the cluster LIFs from the switch that is to be rebooted, and then revert the cluster LIFs after the switch has finished rebooting.

  C. You can migrate Data LIFs to different ports on different nodes.

  D. On each respective switch, use the network interface migrate command to migrate the inter- switch links.

  Correct Answer: C

  Explanation: LIFs are moved to other physical ports within the cluster to provide non-disruptive services.

• Question 15:

  What is NetApp's best practice regarding Ethernet flow control?

  A. Leave flow control enabled.

  B. Disable flow control on the switch ports.

  C. Disable flow control on the host, switch, and all node ports.

  D. Disable flow control on all 10Gbps ports.

  Correct Answer: D

  Explanation: The NetApp Best Practice specifies that Flow Control settings for 10G cluster ports are to be set with Flow Control = None.

• Question 16:

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

  Which tool should the customer use?

  A. System Setup

  B. OnCommand System Manager

  C. HostAgent

  D. StorageGrid

  Correct Answer: B

  Explanation: System Manager is a graphical management interface that enables you to manage storage systems and storage objects (such as disks, volumes, and aggregates) and perform common management tasks related to storage systems from a web browser. As a cluster administrator, you can use System Manager to administer the entire cluster and its resources.

• Question 17:

  You are planning to install a new clustered Data ONTAP system for a customer.

  Which action should be performed before configuring the cluster network switches?

  A. Confirm IP address and configuration information for Brocade switches before configuring the switches.

  B. Use the Cluster Network and Management Network Compatibility Matrix URL before configuring the switches.

  C. Use the Inventory Collect Tool before configuring the switches.

  D. Download the Fibre Channel switches software before configuring the switches.

  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.

• Question 20:

  Which NetApp tool will simplify your initial system installation?

  A. OnCommand Unified Manager

  B. OnCommand System Manager

  C. Config Advisor

  D. System Setup tool

  Correct Answer: B

  Explanation: The System Setup tool enables you to quickly and easily set up your netapp FAS series storage systems using NetApp best practices and optimizing performance for Clustered. You can use this software to configure your network, storage, and protocols with either a single storage controller or multiple controllers.

  Incorrect: Not A: OnCommand Unified Manager is used for to monitor the health of your clustered Data ONTAP environment. Not B: The System Setup tool is for the initial configuration, while OnCommand System Manager is for later configuration. The OnCommand System Manager provides fast, simple configuration and management for NetApp FAS storage systems. Not C: Config Advisor is run on already installed systems. It performs configuration validation for new NetApp system installation and improve automation for service delivery for assessments and audits.
