QUESTION 22What are three volume-level storage efficiency features of ONTAP? (Choose three.)

A. deswizzle

B. space reclamation

C. compaction

D. compression

E. deduplication


Correct Answer: ADESection: (none)Explanation

Explanation/Reference:DE: NetApp deduplication is an integral part of the NetApp Data ONTAP operating environment and the WAFL file system, which manages all data on NetAppstorage systems.

NetApp data compression, introduced in Data ONTAP 8.0.1, is highly complementary to deduplication.

A: Data within a FlexVol has both a logical location within the volume and a physical location within the containing aggregate. When reading data from a FlexVol, thephysical location of that data must be known to perform the read. Under normal circumstances, reads use a fast-path to translate a logical address into a physicaladdress. When SnapMirror transfers a FlexVol to a different aggregate, however, the relationship between logical and physical addresses is changed. Thedestination aggregate lays out the volume into different physical blocks. Immediately after the SnapMirror transfer, reads to the destination volume will use adifferent process to translate logical addresses into physical addresses. This slow-path is less efficient and may require an additional disk read to access a block ofdata. As soon as a FlexVol SnapMirror update finishes, the destination storage controller will launch a scanner to recreate the fast-path metadata. Once the scanfinishes, reads to the SnapMirror destination will use the normal fast-path. This process is known as deswizzling.

QUESTION 23You create a FlexVol volume to host files for a Windows-based application. The administrator of the application is a Windows user. The application does not supportfiles access by Linux users.

Which security style should you assign to the volume?

A. mixed

B. unified

C. NTFS

D. UNIX


Explanation/Reference:You can manage NTFS file security and audit policies on Vservers with FlexVol volumes by using the CLI. This removes the need to use a remote client to managefile security.

Referring to the exhibit, which two actions address the requirement? (Choose two.)

A. Use the network fcp adapter modify command to bring the adapter online.

B. Reboot the node to bring the adapter online after final configuration.

C. Use the system hardware unified-connect command to verify that the port mode is set to initiator.

D. Use the ucadmin modify command to set the adapter mode to FC.


Explanation/Reference:B: Ports must be converted in pairs, for example, 0c and 0d, after which, a reboot is required, and the ports must be brought back to the up state.

D: CNA ports can be configured into native Fibre Channel (FC) mode or CNA mode.

If the current configuration does not match the desired use (here we want to change from CNA mode to FC mode), enter the following commands to change theconfiguration as needed:system node hardware unified-connect modify -node node_name -adapter adapter_name -mode fc|cna -type target|initiator-mode is the personality type, fc or 10GbE cna.-type is the FC4 type, target or initiator.

QUESTION 26An administrator enabled the iSCSI protocol on an SVM and created a LUN for a Windows 2016 system. After rescan, the LUN is not visible on the host.

Which two steps must the administrator take to solve this problem? (Choose two.)


A. Create an initiator group (igroup), add the WWPN of the host initiator, and then map the igroup to the LUN.

B. Disable the ALUA support from the host for the LUN.

C. Configure the iSCSI service on the Windows 2016 system.

D. Create an initiator group (igroup), add the iSCSI IQN, and map the igroup to the LUN.

Correct Answer: CDSection: (none)Explanation

Explanation/Reference:D: An iSCSI qualified name (IQN) identifier is a worldwide unique name that each iSCSI initiator and iSCSI target must have. The IQN for an iSCSI initiator isavailable in Microsoft iSCSI Software Initiator or other iSCSI initiators. Typically the IQN is used by the iSCSI target to identify the iSCSI initiator.


Incorrect Answers:A: A World Wide Port Name, WWPN, or WWpN, is a World Wide Name assigned to a port in a Fibre Channel fabric. Used on storage area networks, it performs afunction equivalent to the MAC address in Ethernet protocol, as it is supposed to be a unique identifier in the network.

B: Asymmetric Logical Unit Access (ALUA), also known as Target Port Groups Support (TPGS), is a set of SCSI concepts and commands that define pathprioritization for SCSI devices.

QUESTION 29A customer has a 1,000 GB volume used as a NAS share that has 3x 100 GB files and has no existing Snapshot copies. The customer creates a Snapshot copy ofthe volume, adds a 500 Gb file to the volume, and then deletes one of the 100 GB files from the volume.

How much free space is in the volume in this scenario?

A. 500 GB

B. 200 GB

C. 300 GB

D. 600 GB


Explanation/Reference:Snapshot copies minimize disk consumption by preserving individual blocks rather than whole files. Snapshot copies begin to consume extra space only when filesin the active file system are changed or deleted. When this happens, the original file blocks are still preserved as part of one or more Snapshot copies.

QUESTION 35


What is an array LUN?

A. a LUN provisioned in ONTAP that is mounted by a connected host

B. a LUN provisioned on third-party storage that ONTAP will use as a passthrough LUN

C. a LUN that is used only as a part of a volume group

D. a LUN provisioned on third-party storage that ONTAP will use in a RAID group


Explanation/Reference:The Data ONTAP software-based scheme provides ownership control only for storage systems running Data ONTAP; it does not prevent a different type of hostfrom overwriting data in an array LUN owned by a system running Data ONTAP. Therefore, if multiple hosts are accessing array LUNs through the same storagearray port, be sure to use LUN security on your storage array to prevent the systems from overwriting each other's array LUNs.

Referring to the exhibit, which two statements are true? (Choose two.)



A. A default tree quota is set on volume svm1_data1.

B. An explicit quota is set on qtree1, and a derived quota is set on qtree2.

C. A derived quota is set on qtree1, and an explicit quota is set on qtree2.

D. A default user quota is set on volume svm1_data1.


Explanation/Reference:A quota enforced as a result of a default quota, rather than an explicit quota (a quota with a specific target), is referred to as a derived quota. To see derived quotas,you can generate a quota report. In the report, a derived user or group quota is indicated by a Quota Specifier that is either blank or an asterisk (*).A derived treequota, however, has a Quota Specifier; to identify a derived tree quota, you must look for a default tree quota on the volume with the same limits. Since they are notmanually configured quota rules, derived quotas do not appear in the output of the quota policy rule show command.

QUESTION 37What is a characteristic of a single-node cluster?

A. It only hosts a single SVM.

B. It does not have a node management LIF.

C. It does not have any cluster interconnect LIFs.

D. It is unsupported in a production environment.


Explanation/Reference:Incorrect Answers:A, B: The following table lists the recommended number of SVMs in a cluster based on the number of LIFs configured:


D: A single node cluster is a special implementation of a cluster running on a standalone node. You can deploy a single node cluster if your workload only requires asingle node, but does not need nondisruptive operations.

QUESTION 39Users report that they are unable to connect to home directories stored on a NetApp cluster. You are using Active Directory-based Kerberos authentication.

Which two actions would correct the problem? (Choose two.)

A. Verify that the CIFS server in running in the SVM.


B. Verify that the Network Time Protocol service is in sync.

C. Verify that an Active Directory domain admin account is configured in ONTAP.

D. Verify that domain tunneling is configured in ONTAP.


Explanation/Reference:Kerberized NFS in Cluster-Mode for use with Active Directory Pre-requisites include:

Domain admin access to a domain controller (for initial setup).vServer with data LIFs, NFS and CIFS servers created

Note: The CIFS server is not required for basic NFS Kerberos access, but is required for multiprotocol access or when using AD as an LDAP server for namemappings.

You have a 2-node NetApp cluster. You perform a storage failover and notice that IP address 10.1.100.21 is unreachable while omegana1-01 is rebooting. Afteromegana1-01 is back online, the IP address becomes reachable again. However, IP address 10.1.100.20 was still reachable during the reboot. The commandsshown in the exhibit were executed before the storage failover.

In this scenario, why was IP address 10.1.100.21 unreachable?

A. The LIF for 10.1.100.21 has an incorrect failover setting.

B. The failover group for 10.1.100.21 is misconfigured.

C. The node management LIFs cannot fail over to other nodes.

D. The Address Resolution Protocol (ARP) cache needs to be cleared on the upstream switch.




The purpose and the default behavior of a LIF is indicated by the role associated with that LIF. Each LIF is assigned a default failover group and failover policy whenyou create the LIF. These settings automatically configure the LIF with a list of failover targets from the ports available in the failover group, so you need tounderstand the relationship between LIF roles and failover groups.

An administrator has a 4-node FAS8200 cluster, as shown in the exhibit. A failover process is initiated to reboot node cl1-02.

Regarding storage failover giveback processes, which statement is true?


A. During giveback, node cl1-01 simultaneously returns ownership of both root and data aggregates to cl1-02.

B. During giveback, node cl1-01 returns ownership of all aggregates to cl1-02, before reverting the data LIFs back to the home ports.

C. During giveback, node cl1-01 returns ownership of the root aggregate to cl1-02 before returning ownership of the data aggregates.

D. During giveback, node cl1-01 moves ownership of the root aggregate to cl1-04 and ownership of the data aggregates to cl1-04.


Explanation/Reference:The following process takes place in a normal giveback. In this discussion, node A has taken over node B. Any issues on Node B have been resolved and it is readyto resume serving data.1. Any issues on node B have been resolved and it is displaying the following message:

Waiting for giveback2. The giveback is initiated by the storage failover giveback command or by automatic giveback if the system is configured for it.3. This initiates the process of returning ownership of the node B's aggregates and volumes from node A back to node B.4. Node A returns control of the root aggregate first.5. Node B proceeds to complete the process of booting up to its normal operating state.6. As soon as Node B is at the point in the boot process where it can accept the non-root aggregates, Node A returns ownership of the other aggregates one at atime until giveback is complete.

Referring to the exhibit, which statement is true?

A. The node’s aggregates have been underutilized on average for the past one hour.

B. The node’s CPU has been underutilized on average for the past one hour.

C. The node’s CPU has been overutilized on average for the past one hour.

D. The node’s aggregates have been overutilized on average for the past one hour.


Explanation/Reference:You compute the available performance capacity by subtracting the optimal_point_counter from the current_counter. In this example, the utilization capacity forCPU_sti2520-213 is -14% (72%-86%). This suggests that the node's CPU has been overutilized on average for the past one hour.

A. directory

B. qtree

C. volume

D. aggregate


Explanation/Reference:You can use SMTape to perform volume backups to tapes.

References: https://library.netapp.com/ecmdocs/ECMP1368865/html/GUID-6C4C53F6-0543-45E1-B03A-891E60F6A109.html

QUESTION 46You are configuring an ONTAP solution for FC host connectivity.

In this scenario, how should the cluster be configured? (Choose two.)

A. The SVM must be configured for Ethernet LIFs.

B. FC ports must be configured as initiators.

C. FCP must be licensed on the cluster.

D. FC ports must be configured as targets.

Correct Answer: AC


Section: (none)Explanation

Explanation/Reference:You can configure the FC and the FCoE protocols on the SVM for SAN hosts. LIFs are created on the most suitable adapters and assigned to port sets to ensuredata path redundancy. Based on your requirements, you can configure either FC, FCoE, or both the protocols.

Before you beginThe FCP license must be enabled on the cluster.All the nodes in the cluster must be healthy.Each node must have at least two correctly configured ports for each protocol (FC and FCoE).

Incorrect Answers:B, D: Onboard ports can be individually configured as either target or initiator FC ports

QUESTION 47When a two-node cluster is expanded, which cluster configuration would be supported?

A. a 4-node switched cluster

B. a 4-node switchless cluster

C. a 3-node switched cluster

D. a 3-node switchless cluster


Explanation/Reference:If you are adding nodes to a two-node switchless cluster, you must have installed and configured the cluster management and interconnect switches before addingadditional nodes.The switchless cluster functionality is supported only in a two-node cluster.

References: https://library.netapp.com/ecmdocs/ECMP1636037/html/GUID-B13FF812-785E-4E62-9914-30E7A8F51A4C.html



In reference to the NFS export-policy rules shown in the exhibit, NFS clients mounted to /data1 from the 192.168.1.0/24, 192.168.2.0/24 and 192.168.3.0/24 subnetsare able to mount /data1 and read files but are unable to edit files or write new files. All other subnets require read-only access to /data1.

What must you do to allow write access to the three subnets while allowing read-only access to all other subnets in this scenario?

A. Set the index of ruleindex 2 to ruleindex 4.

B. Set the index of ruleindex 1 to ruleindex 4.

C. Set the index of ruleindex 3 to ruleindex 4.

D. Set the index of ruleindex 4 to ruleindex 1.


Explanation/Reference:Make sure the rule with ruleindex 1 is applies last.

Note: You can use the vserver export-policy rule setindex command to manually set an existing export rule's index number. This enables you to rearrange the orderin which Data ONTAP processes export rules.

If a client makes an access request that is not permitted by the applicable export policy, the request fails with a permission-denied message. If a client does notmatch any rule in the export policy, then access is denied. If an export policy is empty, then all accesses are implicitly denied.
