You are planning to implement a 32 Gb FC SAN on a 2-node AFF A700 ONTAP 9.5 cluster. You need to create 112 FC LIFs across the HA pair with a limit of 20 FC LIFs per physical HBA port.

In this scenario, how many 2-port 32 Gb HBA cards do you need per storage controller?

A. 2

B. 1

C. 4

D. 3

A company has 20 ESX hosts. Ten of the hosts are connected using FC, and the rest are connected over iSCSI. The FC host HBA queue depth is set to 32, and the iSCSI LUN queue depth is set to 64. The FC hosts are now experiencing random connectivity issues.

In this scenario, what would be the reason for the disconnects?

A. The FC host has a lower queue depth.

B. According to the IMT, unsupported HBA firmware is in use.

C. All of the hosts are part of the same cluster.

D. The queue depth is not consistent across the cluster.

You are about to replace a failed Brocade Fibre Channel switch. Which three steps do you take prior to connecting the switch in the SAN? (Choose three.)

B. Change the domain ID of the replacement switch to the domain ID of the failed switch.

C. Clear all zoning configurations on the replacement switch.

D. Change the core PID format of the replacement switch to the core PID format of the failed switch.

E. Preload the zoning information from the fabric onto the new switch.

A storage administrator created a LUN using two ports on a storage system. Later, additional LUNs were added to the same node as the original LUN. After a while, the performance of the original LUN dropped beyond an acceptable level.

What would you advise to remedy the Issue?

A. Add an additional switch between the hosts and cluster.

B. Add new LIFs on unused ports.

C. Add new LIFs on the used ports.

D. Reduce the queue depth on the used ports.

A database administrator needs to ensure that snapshot copies of database files across multiple LUNs are taken at the same point in time. Which action achieves this outcome?

A. Create each LUN within the same FlexVol volume

B. Create each LUN on the same Fabric Pool aggregate

C. Add each LUN volume to the same snapshot schedule

D. Create each LUN within the same FlexGroup Volume
