NetApp NCSIE NS0-180 Questions & Answers

• Question 1:

  You are setting up a LIF for the node management network.

  What will be the default failover policy in this scenario?

  A. broadcast-domain-wide

  B. system-defined

  C. local-only

  D. sfo-partner-only

  Correct Answer: C

  Explanation: The local-only failover policy is he default setting for cluster LIFs and node

  management LIFs.

• Question 2:

  You are planning to update your running switch environment. You need to determine if certain conditions exist before the FASTPATH software and reference configuration file (RCF) on a NetApp CN16xx cluster switch can be installed.

  Which condition must exist in this scenario?

  A. You must set the port configuration to default for all ports before running the portcfgdefault port- number command.

  B. The cluster must be a fully functioning cluster (no error log messages or other issues).

  C. All ISL ports must be moved to a different switch.

  D. You can only update your switch environment within offline windows.

  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

• Question 3:

  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.

  Correct Answer: C

• Question 4:

  You have completed the installation and verification of the cluster for a customer.

  What is required to complete the event?

  A. Present the customer with the posters included in the boxes.

  B. Call your manager to let them know that you are finished.

  C. Have the customer call NetApp Support to let them know that the installation is complete.

  D. Have the contact sign a document saying that the installation is complete.

  Correct Answer: D

• Question 5:

  A remote administrator is connecting to a cluster from a different remote network.

  According to NetApp best practices, which type of LIF routing is required to accomplish this task?

  A. cluster LIF

  B. data LIF

  C. cluster management LIF

  D. intercluster LIF

  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

• Question 6:

  Click the Exhibit button.

  

  You are asked to install a new cluster with six FAS8060 nodes. While running Config Advisor, you see the messages shown in the exhibit. The customer does not want ACP cabled on their cluster.

  Which two actions would allow the installation to be completed successfully? (Choose two.)

  A. Advise NGS that the customer has a controller in an unsupported state.

  B. Advise the customer that they must acknowledge that they are not using ACP on the installation.

  C. Advise the sales team that the customer is operating without ACP and that the customer is asking you to leave it that way.

  D. Advise the customer that the error will cause the controller to not operate properly and create an unsupported state.

  Correct Answer: BC

  Explanation: After you cable the SAS connections, you have the option to cable the Alternative Control Path (ACP) connections. You should use the ACP protocol because it enables Data ONTAP to manage and control the SAS disk shelf storage subsystem

• Question 7:

  Which two statements are true regarding SSDs? (Choose two.)

  A. SSDs are only available in 400 GB sizes.

  B. SSDs must be in different RAID groups than HDDs.

  C. SSDs are available for multi-disk carrier shelves.

  D. The Maintenance Center is not available for SSDs.

  Correct Answer: BD

  Incorrect:

  Not A: There are, for example, 100 GB, 200 GB, and 800 GB SSD sizes. Not C: Disks in multi-disk carriers

  always have the Data ONTAP disk type of MSATA.

• Question 8:

  Upon completion of an installation, you have begun failover/giveback testing. You notice that when node-02 has been taken over by node-01, node-02 will not respond to ping requests.

  Which statement describes what is happening?

  A. The controller is down and has been taken over by the partner, this is normal behavior during a failover.

  B. The controller that is up, node-01, does not have partner statements in the /etc/rc file.

  C. The controller that is down, node-02, does not have partner statements in the /etc/rc file.

  D. There are no ports in the LIFs' broadcast domain that are linked.

  Correct Answer: C

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

• Question 9:

  You are installing two disk shelves on an existing clustered Data ONTAP system. One shelf is a DS2246 that matches the other shelves in a stack. The other shelf is also a DS2246 but it contains all solid state disks. Both disk shelves must be added to the same stack.

  How would you install the disk shelves?

  A. Install the solid state disks first, then the DS2246 shelf so that the solid state disks are as close to the top of the stack as possible.

  B. Install the spinning disk shelf first and put the solid state disks at the end of the stack.

  C. Advise the customer that solid state disks cannot exist on the same stack as spinning disks.

  D. Move the disk drives around to create two shelves that are half solid state and half spinning drives.

  Correct Answer: A

  Explanation: As SSDs are faster they should be put close to the top of the stack.

  Incorrect:

  Not C: The DS4246 disk shelf only supports high-capacity disk configurations and "Mixed Shelf" SSD

  configurations that combine SSDs with high-capacity disk drives. Not D: Place the SSD disk shelves in a

  separate stack other then the disk shelves containing SAS disks. Because the potential high IOPS, thus

  high SAS I/O bandwidth utilization, we don't want to be limited by our backend SAS I/O. As NetApp states;

  "Full SSD shelves (24 SSDs) are best placed in their own stack".

• Question 10:

  You are assigned to install two DS2246 shelves, three DS4243 shelves, and one DS4486 shelf. How many rack units (U space) should you account for in this rack layout?

  A. 6U

  B. 20U

  C. 10U

  D. 22U

  Correct Answer: B

  Explanation: DS2246 rack units: 2U (Here: 2*2 -> 4U) DS4243 rack units: 4U (Here: 3*4 -> 12U) DS4286 rack units: 4U (Here: 1*4 -> 4U)

  Total: 20U (4+12+4)
