NetApp NCSIE NS0-180 Questions & Answers

• Question 51:

  Multiple customers want to access a cluster from different domains that may contain duplicate IP addresses.

  In this situation, which feature should you use?

  A. IPspaces

  B. interface groups

  C. VLAN

  D. logical interfaces

  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

• Question 52:

  Click the Exhibit button.

  

  You are asked to install a 6-node cluster running clustered Data ONTAP 8.3 using Cisco switches. The customer has installed Config Advisor on a PC on their network and has asked you to help them collect data.

  Referring to the exhibit, which three parameters should be selected? (Choose three.)

  A. Enable management switch connections

  B. Switchless

  C. Enable cluster switch connections

  D. Cisco NX5010/NX5020/5596/5596T

  E. NetApp CN1610/CN1601

  Correct Answer: ADE

  Explanation: In the clustered Data ONTAP profile, you can choose any one of the following (based on the network switch used):

  *

  Cisco NX5010/5020/5596 (Cisco switches is used in this question)

  *

  NetApp CN1610/CN1601

  To verify clustered configurations, you should ensure the following:

  *

  The data is collected from cluster switches, management switches, and a controller.

  Etc.

• Question 53:

  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.

  Correct Answer: C

  Explanation: 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 54:

  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.

  Correct Answer: B

  Explanation: 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 55:

  What is the next step if you must escalate an open case?

  A. Upload the support case and core data files to NetApp Suport and to Engineering.

  B. Clustered Data ONTAP triggers the AutoSupport mechanism automatically again.

  C. Call NetApp Support and ask to speak to the duty manager.

  D. Call NetApp Support and open a new case.

  Correct Answer: C

  Explanation: If at anytime you wish to have your case escalated please call the TSC Hotline

  number and ask to speak to the duty manager.

• Question 56:

  Regarding clustered Data ONTAP 8.3, what happens to the roles of the on board ports, HBAs, and NICs?

  A. These roles are assignet when LIFs are created.

  B. These roles are assigned based on the controller type.

  C. These roles are predefined and must be changed before creating your LIFs.

  D. The roles are divided into two categories: Data Management and Node Management.

  Correct Answer: A

  Explanation: In earlier releases of Data ONTAP, default roles were assigned to each Ethernet network port. The roles included data, cluster, cluster management, intercluster, and node management. In Data ONTAP 8.3, these roles are assigned when LIFs are created.

  Reference: Clustered Data ONTAP 8.3, Network Management Guide, page 7

• Question 57:

  According to NetApp, which two scenarios are recommended for a RAID-DP aggregate in clustered Data ONTAP 8.3? (Choose two.)

  A. three or more disks if it is a data aggregate

  B. three or more disks if it is a root aggregate

  C. two or more disks if it is a root aggregate

  D. five or more disks if it is a data aggregate

  Correct Answer: BD

  Explanation: The minimum number of disks in a RAID-DP group is three: at least one data disk, one regular parity disk, and one double-parity (dParity) disk. However, for non-root aggregates with only one RAID group, you must have at least 5 disks (three data disks and two parity disks).

• Question 58:

  Which switch vendor is supported for the cluster network switches?

  A. Juniper Networks

  B. Cisco

  C. Brocade

  D. Hewlett-Packard

  Correct Answer: B

  Explanation: Cisco Nexus 50x0 switches can be deployed as NetApp cluster network switches. Reference: How to setup and configure the Cluster Network Switch https://kb.netapp.com/support/index?page=contentandid=1012684andlocale=en_US

• Question 59:

  You are installing a 4-node cluster with two CN1610 switches. Your co-worker is setting up the switches, but accidentally deletes the current configuration.

  According to NetApp, what is the recommended way to restore the configuration?

  A. Install only one switch.

  B. Manually configure the ports as they are designated in the CN1601 and CN1610 Switch Setup and Configuration Guide.

  C. Reload the same reference file to the switch.

  D. Copy the configuration from a switch that is working.

  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.

• Question 60:

  You have just configured the customer's first SVM with a LIF IP 10.0.0.10/24. The customer's DNS IP address is 172.16.0.250 and you are unable to ping it from the NetApp storage system, but you are able to ping the gateway and everything else works.

  In this scenario what is the problem?

  A. You need to have the DNS server on the same subnet as the LIF IP address.

  B. You need to add a static gateway to the LIFs routing group.

  C. You need to have the customer check the cable.

  D. You need to add an IPspace and domain broadcast to the port.

  Correct Answer: D

  Explanation: A broadcast domain resides in an IPspace, and it contains a group of network ports, potentially from many nodes in the cluster, that belong to the same layer 2 network. The ports in the group

  are used in an SVM for data traffic.
