Question No : 2
Multiple customers want to access a cluster from different domains that may contain duplicate IP addresses.
In this situation, which feature should you use?

正解:
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 No : 3

Question No : 4
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?

正解:
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 No : 5
Which technology allows NetApp to ship replacements for defective parts automatically?

正解:
Explanation:
The NetApp AutoSupport family helps you optimize your data center by providing simple, effective, proactive monitoring and management of your storage infrastructure. AutoSupport is an integrated and efficient monitoring and reporting technology that checks the health of AutoSupport-enabled NetApp systems on a continual basis. It’s an effective troubleshooting tool for you and for the NetApp Support team. Remote Support Diagnostics Tool (RSDT) helps NetApp Support solve storage-system issues for you―without your intervention. My AutoSupport is a Web-based application that works with AutoSupport.
Incorrect: Not A: System-level diagnostics (SLDIAGs) provides a command-line interface for tests that search for and determine hardware problems on supported storage systems. You use system-level diagnostics to confirm that a specific component is operating properly or to help identify faulty components. Not B: OnCommand System Manager provides fast, simple configuration and management for NetApp FAS storage systems. Not C: Call Home is a function within AutoSupport. You can verify that AutoSupport is working by using the Call Home Check function.

Question No : 6
What is s LIF?

正解:
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

Question No : 7
A customer is installing a new system and has determined that they have a broken disk.
What information is required to open a NetApp Support case?

正解:

Question No : 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?

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

Question No : 9
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?

正解:
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 On the recovering node, use the system configuration recovery cluster recreate command at the advanced privilege level to re-create the cluster. Use the cluster identity show command to verify that the recovering node has a different UUID than the other nodes. 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 re­created cluster before you can rejoin another node.

Question No : 10
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?

正解:
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 No : 11
You are creating a first data aggregate on the fourth node of a clustered Data ONTAP system that has only 600 GB SAS disks.
According to the NetApp naming convention, what is the appropriate name for the aggregate?

正解:
Explanation:
Example of appropriate name: n01sas01 Underscores can be used, but not "." or "-". Note: Aggregate names must conform to the following requirements: They must begin with either a letter or an underscore (_). They can contain only letters, digits, and underscores. They must contain 250 or fewer characters.

Question No : 12
You are adding nodes to an existing cluster.
In this scenario, which three statements are correct? (Choose three.)

正解:
Explanation:
C: If you are adding nodes to a multiple-node cluster, more than half of the existing nodes in the cluster must be healthy (indicated by cluster show).
E: If you are adding nodes to a two-node switchless cluster, you must have installed and configured the cluster management and interconnect switches before adding additional nodes. Incorrect: not A: If you are adding a second node to a single-node cluster, the second node must be installed, and the cluster network must be configured. Not D: The switchless cluster functionality is supported only in a two-node cluster.

Question No : 13
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?

正解:
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.
Reference: Clustered Data ONTAP 8.3, Network Management Guide, page 8

Question No : 14
You have completed a clustered Data ONTAP installation for a new customer. You are now ready to hand off the system to the customer.
Which three actions should you take at this stage in the installation process? (Choose three.)

正解:

Question No : 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?

正解:
Explanation:
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.
