NS0-506 Online Practice Questions and Answers

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

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 showyou see the ESX host's initiators; however, they are listed "not logged in".

What is the problem?

A. You need to configure ALUA.

B. The LUN was not put online.

C. The LUN type is not set to type VMware.

D. You need to configure zoning.

Which two port personality combinations are valid for the onboard UTA2 ports on a FAS8040 controller?

A. e0e/0e - fc e0f/0f - fc e0g/0g - cna e0h/0h -cna

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

Which two flags would you use to enable NetApp thin provisioning on a LUN? (Choose two.)

A. -space-reserve enabled -space-allocation enabled

B. -space-reserve enabled -space-allocation enabled

C. -space-reserve disabled -space-allocation disabled

D. -space-reserve disabled -space-allocation enabled

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

Exhibit

You currently have the following configuration on your cluster:

cl01::>igroup show -instance Vserver Name: svm1 Igroup Name: ig2 Protocol: mixed OS Type: linux Portset Binding Igroup: -Igroup UUID: 3fb136c7-cfd6-11df-a9ab-123478563412

Initiators:

What must you do to limit the LIFs that are used by an initiator to access a LUN?

A. Create a portset.

B. Create an additional igroup.

C. Change the protocol to iSCSI.

D. Change the OS type to windows_gpt.

A customer has a 4-node cluster and wants to use iSCSI for LUN traffic. Which license needs to be installed on the nodes?

A. iSCSI

B. SnapRestore

C. CIFS

D. FC

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.

Exhibit

cl01::>lun mapping show vserver svm1 path /vol/svm1_vol1/lun1 igroup svm1-ig1 Vserver Name: svm1 LUN path: /vol/svm1_vol1/lun1 Volume Name: svm1_vol1 Qtree Name: "" LUN Name: lun1 Igroup Name: svm1-ig1 Igroup OS Type: windows

Igroup Protocol Type: iscsi LUN ID: 3 Portset Binding Igroup: ALUA: true Initiators: iqn.199105.com.microsoft: host1 LUN Node: cl01-04 Reporting Nodes: cl01-01, cl01-02, cl01-03, cl01-04

You have a 2-node cluster. You have added an HA pair with all flash drives for a high- performance database that is currently experiencing performance problems on SAS drives. The LUN shown in the exhibit is moved from cl01-01 to cl01-04 to address the problems.

What is the next step in this scenario?

A. Rescan the host to discover the new LUN location.

B. Remove the old path entries from the host.

C. Remove the previous owner and partner from the reporting nodes list.

D. Unmap the LUN, then remap the LUN.

You are asked to configure the Service Processor on a newly installed node, and must verify the following command:

system-service processor network modify -node local -address-family IPv4 -enable true -ip-address 192.168.123.98 -netmask 255.255.255.0

Which statement about this command is true?

A. -nodeshould reference the actual node name.

B. The gateway IP address is missing.

C. The Link Local IP Address is missing.

D. IPv6 is required for the SP.
