Q1. Which feature provides preferred protection for the root volume of a storage virtual machine (SVM)?
A. SnapVault
B. load-sharing mirror
C. SnapMirror
D. SyncMirror
Answer: B
Explanation:
To protect the Storage Virtual Machine (SVM) namespace root volume, you can create a load-sharing mirror volume on every node in the cluster, including the node in which the root volume is located. Then you create a mirror relationship to each load-sharing mirror volume and initialize the set of load-sharing mirror volumes.

Q2. 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.
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

Q3. 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.
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.

Q4. What is s LIF?
A. a logical internet file
B. a logical inventory file
C. a logical interaction file
D. a logical interface
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.

Q5. What is a protocol?
A. SnapRestore
B. CIFS
C. SnapMirror/SnapVault
D. FlexClone
Answer: B
Explanation:
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.

Q6. A customer learns that a certain NetApp tool allows remote data collection, intelligent core file handling, and notification of down storage controllers for technical support analysis and troubleshooting.
What is the name of this tool?
A. RSA
B. HWU
C. Synergy
D. HW Assist
Answer: A
Explanation:
Remote Support Agent (RSA) is a remote diagnostics data collector that is embedded directly into the storage controller's remote management device firmware. Remote Support Agent enables a NetApp support engineer to remotely request an automated upload of log files, core files, and other diagnostic information stored in the storage controller and to remotely trigger an on-demand AutoSupport collection. Incorrect: Not B: The Hardware Universe (HWU) application is NetApp's system configuration solution. Not C: NetApp Synergy is a complete design, deployment and documentation tool. The program enables you to build a very accurate, detailed model of a NetApp storage system. You can represent most aspects of a storage deployment including the hardware configuration and the sizing of all storage containers, including aggregates, volumes, qtrees and LUNs.

Q7. 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.
Answer: B Explanation:
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.

Q8. You want to support multiple tenants with duplicate IP addresses for your storage system.
Which statement is correct in this scenario?
A. You must create additional VLANs to use multiple tenants.
B. You must create an additional IPspace.
C. You cannot support multiple tenants on your storage system.
D. You must use different ports on your controller.
Answer: B
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.
