An 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.

Answer: CD
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 is available in Microsoft iSCSI Software Initiator or other iSCSI initiators. Typically the IQN is used by the iSCSI target to identify the iSCSI initiator.

Which two features provide physical path resiliency from a Windows 2016 server to an iSCSI LUN on a 12-node ONTAP cluster? (Choose two.)

A.    broadcast domains
B.    MPIO
C.    failover groups
D.    ALUA

Answer: BD
Microsoft Multipath I/O (MPIO) is a Microsoft-provided framework that allows storage providers to develop multipath solutions that contain the hardware-specific information needed to optimize connectivity with their storage arrays. These modules are called device- specific modules (DSMs). The concepts around DSMs are discussed later in this document. MPIO is protocol-independent and can be used with Fibre Channel, Internet SCSI (iSCSI), and Serial Attached SCSI (SAS) interfaces in Windows Server. Asymmetric Logical Unit Access (ALUA), also known as Target Port Groups Support (TPGS), is a set of SCSI concepts and commands that define path prioritization for SCSI devices.

Referring to the exhibit, which statement about the volume move process is true?

A.    Client access to the volume is blocked during this phase of operation.
B.    The initial replication phase sent 39 MB from the source to the destination location.
C.    Client access is being redirected to the destination location during this phase of the operation.
D.    The cutover process failed and is in a holding pattern before being attempted again.

Answer: B

While reviewing the port health shown in the exhibit, you notice that port e0c on node1 is degraded.
What would cause this problem?

A.    The port is not plugged into a switch.
B.    The port is in the wrong broadcast domain.
C.    The port does not have an IP address.
D.    The port has been flapping.

Answer: B
l2 reachability health monitor: Monitors whether all ports configured in the same broadcast domain have l2 reachability to each other. This health monitor reports l2 reachability issues in all IPspaces; however, it marks only the ports in the cluster IPspace as degraded.

You have a read-only volume that needs protection within the cluster, but you do not have a SnapMirror license. Which mirror type would you use to protect the volume?

A.    DP
B.    LS
C.    TDP
D.    XDP

Answer: B
A load-sharing mirror reduces the network traffic to a FlexVol volume by providing additional read-only access to clients. You can create and manage load-sharing mirrors to distribute read-only traffic away from a FlexVol volume.

Referring to the exhibit, you have a FlexGroup volume that is 250 TB with 10 constituents. You apply the volume modify -vserver fg1_vs -volume fg1 -size 350TB command. What affect does the command have on the FlexGroup volume and its constituents?

A.    It grows the FlexGroup volume to 600 TB by adding 14 new constituents.
B.    It grows the FlexGroup volume to 350 TB by adding 4 new constituents.
C.    It grows the FlexGroup volume to 350 TB by increasing the size of each constituent to 35 TB.
D.    It grows the FlexGroup volume to 600 TB by increasing the size of each constituent to 60 TB.

Answer: C
If you want to add more space, you can increase the FlexGroup volume collective size. Increasing the size of the FlexGroup volume resizes the existing constituents of the FlexGroup. If you want to increase the capacity by resizing the existing constituents then use the command:
volume modify -vserver vserver_name -volume fg_name -size new_size

A customer has created an SVM in an 8-node cluster with only FC licensed on all nodes. The customer wants to limit the number of paths visible to each host. Which three technologies accomplish this task? (Choose three.)

A.    Virtual SANs (VSANs) for all FC target ports to segment specific virtual ports in mapping to the application servers
B.    SLM to limit the paths from each node to the appropriate application servers
C.    FC switch zoning of a subset of the target ports to each application server’s HBAs
D.    Port sets to limit the paths from each node to the appropriate application servers
E.    Multipathing to limit the access to the LUNs from each host

Answer: BCD
You can use FC switch zoning, portsets, and Selective LUN Map (SLM) to limit the number of paths between hosts and LUNs in configurations with multiple target ports connected to the same fabric. (page 20)

You are receiving reports of high storage latency from the database administrators. The NetApp storage system is connected to the network using 10 Gb. You run the sysstat command as shown in the exhibit. In this scenario, why is storage latency high?

A.    The system does not have enough cache.
B.    The system is experiencing a disk bottleneck.
C.    The CPU usage is too high.
D.    The network interfaces are maximized out.

Answer: B

The size of the aggr1 RAID group shown in the exhibit is 8.
What is the RAID type?

C.    RAID4
D.    RAID0
