B. Fibre Channel over Ethernet (FCoE) enables the transport of Fibre Channel traffic over Ethernet networks by encapsulating Fibre Channel frames over Ethernet networks.

Which of the following allows you to provide security to the data contained in a storage array? A. Trunking B. LUN masking C. LUN provisioning D. Multipathing

B. LUN masking enforces access policies to storage resources, and these storage policies make sure that the data on those devices is protected from unauthorized access.

Warren is a systems administrator working in a corporate data center, and he has been tasked with hiding storage resources from a server that does not need access to the storage device hosting the storage resources. What can Warren configure on the storage controller to accomplish this task? A. Zoning B. LUN masking C. Port masking D. VLANs

B. LUN masking is executed at the storage controller level instead of at the switch level. By providing LUN-level access control at the storage controller, the controller itself enforces access policies to the devices, making it more secure. This is the reason that physical access to the same device storing the LUNs remains "untouchable" by the entity using it.

Which of the following would increase availability from a virtualization host to a storage device? A. Trunking B. Multipathing C. Link aggregation D. VLANs

B. Multipathing creates multiple paths for the computer to reach the storage resources it is attempting to contact, improving fault tolerance and possibly speed.

Which provisioning model would you use if data is added quickly and often? The solution must ensure consistent performance. A. Thin provisioning B. Thick provisioning C. Overprovisioning D. Encryption

B. Thick provisioning would consume all the allocated space upon creation of the LUN, but performance would be consistent for a LUN that expects data to be added quickly and often because storage would not need to be continually allocated to the LUN and the storage would not be fragmented.

Which term describes the ability for an organization to store data based on performance, cost, and availability? A. RAID B. Tiered storage C. SSD D. Tape drive

B. Tiered storage refers to the process of moving data between storage devices based on performance, cost, and availability.

Which type of storage system is directly attached to a computer and does not use a storage network between the computer and the storage system? A. NAS B. SAN C. DAS D. Network share

C. DAS is a storage system that directly attaches to a server or workstation without a storage network in between the devices.

What RAID level would be used for a database file that requires minimum write requests to the database, a large amount of read requests to the database, and fault tolerance for the database? A. RAID 10 B. RAID 1 C. RAID 5 D. RAID 0
