Given the below system requirements:

-Two Fabrics

-Each fabric has 4 switches, 1 core director and 3 edge switches

-A new storage array is being added

-HA environment that is fully redundant

Where would a storage administrator MOST likely place the storage and how many connections would the administrator need to connect the array to the environment?

A. Connected to the core; all connections from the storage array controller 1 go to fabric A and controller 2 goes to fabric B.

B. Connected to the edge switches; each controller has its connections balanced between all edge switches on both fabrics.

C. Connected to the edge switches; controller 1 has its connections balanced between all edge switches on fabric A, controller 2 has its connections balanced between all edge switches on fabric B.

D. Connected to the core; half of the connections to each storage array controller connects to each of the fabrics.

An administrator would like to combine several ISLs into a single virtual connection. Which of the following technologies should be implemented to accomplish this?

A. LUN Masking

B. Trunking

C. Flow Control

D. VLAN Trunking

An administrator has just replaced a single-port HBA and needs to complete zoning changes to replace the current alias. The administrator creates the new alias, adds it to the existing zone, and then deletes the old alias. When applying the new configuration, an error states that the originalalias is not found and the configuration cannot be applied. Which of the following steps did the administrator miss?

A. Create a new zone with the new alias and add it to the existing configuration

B. Remove the original zone and recreate it with the new alias.

C. Rename the original alias before deleting it.

D. Remove the original alias from the zone before deleting it.

Which of the following BEST prevents unauthorized access to storage data via a username/password?

A. ACL

B. Encryption

C. Physical access restrictions

D. Compression

On a Fibre Channel switch, port error counters for one storage port show a high number of CRC errors, invalid transmit words, and bad end of frames. Which of the following are the MOST likely causes? (Select TWO).

A. Failing Switch ASIC

B. Failing HBA/SFP on storage

C. Loose or damaged cable

D. Server is rebooting

E. HBA driver

Which of the following storage techniques places frequently accessed data on faster media while placing seldom accessed data on slower media?

A. Defragmenting

B. De-duplication

C. Thin provisioning

D. Tiering

A dual controller head storage array is zoned to two different fabrics. How should the administrator cable up the storage array to ensure redundancy and resiliency?

A. ISL the FC switches together

B. Cable both controller heads to one switch

C. Have at least one path from each controller head going to each fabric

D. Cable one controller port to one fabric and the other controller port to a second fabric

A large number of intermittent SCSI errors are suddenly appearing in a host's log, but the storage array has been verified as fully operational. The link lights on the SAN switch connections have been confirmed. Which of the following should a storage administrator check?

A. Switch zone errors

B. Port errors counters

C. FC cable

D. HBA topology configuration

An administrator is troubleshooting an outage in which a core switch in one of the redundant fabrics has failed. The servers connected to one of the storage arrays lost access to their assigned LUNS, while servers with LUNs assigned from other storage arrays continue to have access. Which of the following caused the outage?

A. The array controllers were not configured for failover.

B. The array has only one controller.

C. All controllers of the array are connected to the failed fabric.

D. Servers' redundant HBAs have incompatible firmware.

The name server shows an FC switch port connected to a VM Server with 6 different WWPNs. This is an example of which of the following?

A. Multipathing

B. VSAN

C. Virtual fabric

D. NPIV
