• Question 2:

  A. Install only one switch.
  B. Manually configure the ports as they are designated in the CN1601 and CN1610 Switch Setup and Configuration Guide.

  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 3:

  You want to create a data volume on aggr0 and you receive a message with the following warning:

  ''Warning: You are about to create a volume on a root aggregate. This may cause severe performance or stability problems and therefore is not recommended. Do you want to proceed?''

  What is the reason for this severe performance or stability problem?

  A. Controller failover and storage failover are separate processes that must occur in parallel, otherwise problems will arise.
  B. The performance load generated by the data volume can be very strong, so it should not be shared with vol0 on aggr0, requiring a separate aggregate for it.
  C. The performance load generated by the vol0 cannot be shared with any other volume on aggr0, requiring a dedicated aggregate for it.
  D. Controller failover and storage failover are separate processes that must occur at different times, otherwise problems will arise.
  B. The performance load generated by the data volume can be very strong, so it should not be shared with vol0 on aggr0, requiring a separate aggregate for it.

  ---

  One possibly cause is Disk I/O contention on the data volume.

  The root volume in Cluster-Mode is used to store and update various tables of the replicated database. Crucial information regarding the locations of LIFs, volumes, aggregates, and different jobs required to run in the cluster are stored in

  these tables. If a root aggregate has very busy data volumes, the disks in the aggregate will experience higher latency. When a node is unable to update its copy of the replicated database fast enough, it will consider itself unhealthy and stop

  serving all the data until it can catch up. This is extremely disruptive and affects all the volumes on the node, even if the cause is related to the data volumes stored on the root aggregate only.

  Reference: Why is a warning displayed when attempting to create one or more data volumes in the root aggregate in Data ONTAP Cluster-Mode?

• Question 4:

  A customer wants you to add a disk shelf that contains SSDs so they can implement Flash Pool. Which three tools would you use to complete this task? (Choose three.)

  A. Use the My AutoSupport tool to ensure that Flash pool is licensed.
  B. Use Hardware Universe to ensure that you would not exceed the maximum drive count.
  C. Use Hardware Universe to ensure that you would not exceed the maximum cache for the system.
  D. Use the My AutoSupport tool to see if there is a Flash Cache card installed.
  E. Use Config Builder to verify the shelves can be added.
  A. Use the My AutoSupport tool to ensure that Flash pool is licensed.
  B. Use Hardware Universe to ensure that you would not exceed the maximum drive count.
  E. Use Config Builder to verify the shelves can be added.

  ---

  The Hardware Universe (HWU) application is NetApp's system configuration solution, replacing the System Configuration Guides.

• Question 5:

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

• Question 6:

  What is a protocol?

  A. SnapRestore
  B. CIFS
  C. SnapMirror/SnapVault
  D. FlexClone
  B. CIFS

  ---

  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 7:

  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
  C. NFS. CIFS

  ---

  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. Reference: Clustered Data ONTAP 8.3, Network Management Guide, page 96

• Question 8:

  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
  B. data LIF

  ---

  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

  B. Cisco Nexus 5020 Expansion Module
  C. Cisco Catalyst 2960
  D. Cisco Catalyst 5000
