NetApp NS0-180 Online Practice Questions and Exam Preparation

NetApp NS0-180 Online Questions & Answers

• Question 11:

  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.
  D. Disable flow control on all 10Gbps ports.

  ---

  The NetApp Best Practice specifies that Flow Control settings for 10G cluster ports are to be set with Flow Control = None. Reference: How to modify the Flow Control setting on clustered Data ONTAP cluster ports https://kb.netapp.com/support/index?page=contentandid=1015245andactp=LIST_RECENT

• Question 12:

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

  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:

  You want to install a new clustered Data ONTAP 8.3 system with a FA8080. The customer has unused licenses available from a clustered Data ONTAP 8.1 system. What should be considered in this scenario?

  A. You can use your licenses from the clustered Data ONTAP 8.1 system for the new clustered Data ONTAP system.
  B. You must call NetApp Support for evaluation license keys.
  C. You can use your license from the clustered Data ONTAP 8.1 system for about 90 days.
  D. In clustered Data ONTAP 8.2 and later, use node-specific license keys that will only install on the controller for which they were purchased.
  B. You must call NetApp Support for evaluation license keys.

  ---

  Any clean installation of Data ONTAP requires version-appropriate license keys for the Data ONTAP version and mode being deployed. Current policies require a valid support case to provide new license keys for Data ONTAP versions other than the version originally purchased.

• Question 14:

  After proper cabling the NetApp CN1610 cluster switches, you notice that joining the second node to a cluster fails because the node is not able to communicate with the other node. What would be the reason for this malfunction?

  A. CN1610 is unsupported in newer clustered Data ONTAP versions.
  B. The NTP server is not set.
  C. The FASTPATH version is not supported.
  D. The cluster switches must be Cisco switches for two or more nodes in a cluster.
  C. The FASTPATH version is not supported.

  ---

  Before you set up NetApp CN1610 cluster switches verify that you have the appropriate FASTPATH firmware and reference configuration file (RCF) versions for your version of Data ONTAP.

  Incorrect:

  Not A, Not C: NetApp CN1610 will work fine. If you have an existing two-node switchless cluster environment, you can migrate to a two-node switched-cluster environment using CN1610 cluster network switches.

• Question 15:

  A customer is installing a new system. The administrator needs to have the maximum available amount of data space. Which disk configuration should the administrator use?

  A. RAID-DP
  B. RAID4
  C. Flash Pool
  D. ADP
  D. ADP

  ---

  Advanced drive partitioning to increase usable capacity for entry systems, all-flash FAS, and Flash Pool.

  Incorrect:

  Not A: RAID-DP is useful for maximizing data protection, but it does not provide the maximum available data space. Not B: RAID4 is useful for optimizing writes, but it does not provide the maximum available data space.

• Question 16:

  You want to install a new clustered Data ONTAP 8.3 system. The customer wants to use open ports on interconnect switches from a different system with clustered Data ONTAP 8.2 because they are running out of space in their rack. What should be considered in this scenario?

  A. Only one cluster per switch pair is qualified and supported.
  B. You can use all free network ports for the cluster interconnect.
  C. You can only use dedicated ports for the clustered interconnect.
  D. A maximum of two clusters per switch pair are qualified and supported, but you should use trunked ports.
  C. You can only use dedicated ports for the clustered interconnect.

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

  ---

  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 7-Mode storage systems, hosts, and host applications. The inventory report can then be imported to the 7-Mode Transition Tool for

  transition assessment.

• Question 18:

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

  ---

  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.
