A customer has a volume with the configuration shown in the exhibit.

What will happen if the volume vs_iscsi_exch01 reaches 85% used?

A. The volume will delete snapshots until 20% is free in the volume.

B. The volume will automatically grow up to 6 GB.

C. The volume will no longer be accessible from the host.

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

A customer is configuring their host for FC connectivity to a clustered Data ONTAP storage solution. They have installed a 4 GB FC HBA into the host and connected it with optical cables to an 8 GB FC switch. They have also connected the UTA2 ports from the FAS2552 with 16 GB SFP+ optics installed using optical cables to the switch.

Which two actions will improve host FCP throughput? (Choose two.)

A. replacing the existing 8 GB FC switch with a new 16 GB FC switch.

B. replacing the switch with a 10 GB Ethernet switch

C. adding 16 GB FC HBA and appropriate optics

D. replacing the optical cables with copper TwinAx cables.

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.

A Windows 2012 Server has a 1 GB thin-provisioned LUN in a 10 GB thin-provisioned volume. After copying a 500 MB file to the LUN, you observe the LUN using 500 MB of space in the volume. After deleting the 500 MB file, you observe the LUN is still using 500 MB of space in the volume.

Which two steps are required to reclaim the space? (Choose two.)

A. Press Optimize in the Windows Defragment and Optimize Drives utility.

B. Enable space-allocationon the LUN.

C. Run TRIM on the host.

D. Empty the Recycle Bin on the host.
