QUESTION 31
What does Selective LUN Mapping (SLM) do?
A. It automates igroup creation.
B. It allows the node and its HA partner to create zones on the SAN fabric to automate LUN mapping.
C. It makes a LUN accessible only through paths on the node owning the LUN and its HA partner.
D. It allows the administrator to automatically create LUNs using SnapDrive for Windows and SnapDrive for UNIX.
Answer: C
Explanation:
Selective LUN Map (SLM) reduces the number of paths from the host to the LUN. With SLM, when a new LUN map is created, the LUN is accessible only through paths on the node owning the LUN and its HA partner.
SLM enables management of a single igroup per host and also supports nondisruptive LUN move operations that do not require portset manipulation or LUN remapping.
Portsets can be used with SLM just as in previous versions of Data ONTAP to further restrict access of certain targets to certain initiators . When using SLM with portsets, LUNs will be accessible on the set of LIFs in the portset on the node that owns the LUN and on that node’s HA partner.

QUESTION 36
Click the Exhibit button.
Referring to the diagram shown in the exhibit, what will happen if PDU-B fails?
A. Both Node A and Node B will remain online and all disk shelves will remain online.
B. Both Node A and Node B will remain online, but all disk shelves will immediately lose power and become inaccessible.
C. Both Node A and Node B willimmediately lose power and become inaccessible.
D. Node A will immediately lose power and become inaccessible. Node B will remain online.
Answer: A
QUESTION 37
Hosts and switches are connected to a FAS8040.
Multiple FC-enabled SVMs have been created, and LUNs have been mapped to multiple hosts.
During failover testing, one of the hosts lost connectivity to its LUNs.
What needs to be examined?
A. FAS8040 ALUA configuration
B. host multipath settings
C. xhost iSCSI timeout values
D. switch NPIV settings
Answer: B
QUESTION 38
Click the Exhibit button.
Based on the exhibit, you are configuring a 4-node cluster with an iSCSI LIF ob each node.
You connect using the first LIF from a Windows Server 2012 host.
How would you add the other three LIFs?
A. Use the MCS button.
B. Use the Devices button.
C. Use the Add session button.
D. Wait and then press the Refresh button until the other sessions appear.
Answer: C
QUESTION 39
You have a 4-node FAS8040 cluster licensed for FCP and iSCSI. Each node has both FC and iSCSI LIFs. One of your Windows 2012 Servers has a single 8Gb FC port and a single 10 Gb Ethernet port with switched connectivity to the FC and Ethernet ports on the cluster.
You need to use both ports on the host for multipath access to a LUN on the NetApp cluster.
What will accomplish this task?
A. NetApp Data ONTAP DSM for Windows MPIO
B. FCoE HBA
C. iSCSI HBA
D. native Windows MPIO
Answer: A
QUESTION 40
A customer has a clustered Data ONTAP solution and needs to connect several Windows 2012 servers using iSCSI for LUN access.
Before the LUN can be seen, what must be configured on the host?
A. the LUN partitioning
B. the Host Utilities Kit
C. the iSCSI software initiator
D. the HBA queue depth
Answer: C
QUESTION 41
You have executed the following FC configuration workflow:
1. Verify IMT supported configuration.
2. Install VSC for VMware vSphere on a Windows Server.
3. Add the storage cluster to VSC and set recommended values.
4. Update host HBA firmware and BIOS.
5. Provision the LUN.
6. Manually create an igroup and add the host WWPNs into it.
7. Map the LUN to the igroup.
8. Create datastore and its containing LUNS and volumes.
In step 8, you are not able to see the LUNs you provisioned on your storage controller.
When you run igroup show you see the ESX host’s initiators; however, they are listed “not logged in”.
What is the problem?
A. You need to configure ALUA.
B. TheLUN was not put online.
C. The LUN type is not set to type VMware.
D. You need to configure zoning.
Answer: D
