A new server has been installed in your environment, but it is unable to see its NetApp boot
LUN. You have narrowed the problem down to the zoning on your Cisco switch which has the following configuration: zone name z_NetAppvsan 400 memberpwwn 20:00:00:25:b5:c0:ff:ee memberpwwn 50:0a:09:84:8d:7c:51:d5 zoneset name zs_NetAppvsan 400 memberz_NetApp zoneset activate name zs_NetAppvsan 400
What is the problem with your zoning configuration?
- A. The member does not reference the VSAN.
- B. The zone and zoneset names do not match.
- C. The zoneset was improperly activated.
- D. The PWWN for your NetApp LIF is incorrect.
Answer : D

- C. fcping
- D. zoneshow
Answer : B
A volume with a single LUN shows 30% deduplication savings. However, the output of df on the cluster does not show the 30% savings back to the volume or aggregate.
What is causing this behavior?
- A. Volume space guarantee is set to none.
- B. Volume space guarantee is set to volume.
- C. LUN space reserve is disabled.
- D. LUN space reserve is enabled.
Answer : A

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
A customer has recently deployed a clustered Data ONTAP 8.3 system and is trying to mount LUNs to a Windows 2012 Server using the iSCSI protocol. They are using Cisco
Nexus 5548 network switches and the network administrator has informed the storage administrator that the ports are set to switchport mode trunk. The storage administrator has also been informed that the host and storage should be using VLAN 400 for iSCSI traffic.
When the storage administrator attempts to add the SVM as an iSCSI target, it fails to connect.
What is causing the problem?
- A. The storage administrator has not enabled VLAN tagging on the storage ports.
- B. Clustered Data ONTAP 8.3 does not support the iSCSI protocol on a VLAN tagged interface.
- C. Windows 2012 Server does not support the iSCSI protocol on a VLAN tagged interface.
- D. Clustered Data ONTAP 8.3 does not support running iSCSI on a VLAN ID below 1024.
Answer : A
You have a new FAS8080EX 2-node cluster. The FC switch ports connected to the onboard UTA2 ports will not come online.
Which two node-based issues would case the problem? (Choose two.)
- A. The UTA2 ports are set to target.
- B. The UTA2 ports have 10 GB SFP+ optics installed.
- C. The UTA2 ports have 16 GB SFP+ optics installed.
- D. The UTA2 ports are in cna mode.
Answer : A,D
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.

A customer has a host experiencing performance problems with its FC LUNs. The customer has examined the nodes hosting the LUNs, and both the disk and CPU performance are below 50% utilization. The customer examined the switch ports connected to the storage array, and they are also below 50% utilization.
Which three should the customer verify? (Choose three.)
- A. that the HBA queue depth is set properly
- B. that the host HBA has the correct port settings
- C. that the host Ethernet interfaces are using jumbo frames
- D. that the host is running SnapDrive
- E. that the FC switch ports connected to the host have not exceeded the maximum capacity
Answer : A,C,D
You recently configured your SVM to serve data with the FC protocol by issuing the following commands:
However, your LIF still shows an operational status of down.
What must you do to change the operational status to up?
- A. Configure zoning on the switch.
- B. Create a LIF on the node’s HA partner.
- C. Add the LIF to a igroup.
- D. License and enable the FC service.
Answer : D

A company has a 4-node Data ONTAP cluster called cl01. Each node uses two UTA2 ports for data traffic, so that both LAN and SAN traffic pass over the same physical ports. A storage virtual machine called svm1 is created and enabled for iSCSI only. An administrator creates a LUN named svm1 and maps it to an igroup. Storage is scanned on the end host but the LUN is not visible.
What caused this problem?
- A. The SVM firewall policy is blocking port 3260 on the data LIFs.
- B. One of the LIFs is not online and communicating with the end host.
- C. Switch zoning is not configured properly to allow connectivity.
- D. The igroup does not contain the appropriate initiators.
Answer : D
Which two port personality combinations are valid for the onboard UTA2 ports on a
FAS8040 controller?

- B. e0e/0e – fc e0f/0f – cna e0g/0g – fc e0h/0h –cna
- C. e0e/0e – fc e0f/0f – fc e0g/0g – fc e0h/0h –cna
- D. e0e/0e – cna e0f/0f –cna e0g/0g – fc e0h/0h – fc
Answer : C
