Correct Answer: D

Explanation: Up to 10 shelves are supported per stack for the DS2246, so we one stack is enough as we only have five shelves (DS2246s). Reference: Making the Move from FC to SAS Storage http://www.netapp.com/as/communities/tech-ontap/tot-fc-sas-1101-as.aspx

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.

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

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.

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.

Reference: Config Advisor 3.2. Installation and Administration Guide, page 21

Correct Answer: D

Explanation: A LIF (logical interface) is an IP address or WWPN with associated characteristics, such as a role, a home port, a home node, a list of ports to fail over to, and a firewall policy. You can configure LIFs on ports over which the cluster sends and receives communications over the network.

Reference: Clustered Data ONTAP 8.3, Network Management Guide, page 54

Correct Answer: C

Correct Answer: CD

Explanation: C: You need the following network information for all switch configurations: *Two or more IP subnet addresses for cluster network and management network traffic

*

Host names and IP addresses for each of the controllers and all applicable switches

*

Management network port assignments for your controller

D: To configure your cluster, you need the appropriate number and type of cables and cable connectors for your switches. Depending on the type of switch you are initially configuring, you need to connect to the switch console port with the included console cable.

Correct Answer: AB

Explanation: A: Check that the mail host specified in the options is a host that the storage system can talk

to, by running the following command on the storage system:

ping mailhost_name

mailhost_name is the name of the mail host specified in the AutoSupport options.

B: The customer firewall must let SMTP (port 25) messages go through their firewall.

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)

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

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
