A. Data Progression moves data from the pagepool class into another class

B. System allocates more raw space for use by the pagepool class

C. Performance is degraded for volumes with active data in the pagepool class

D. Data Progression no longer moves data into the pagepool class

Correct Answer: D

Question 2

What are the effects of pre-allocating space on a volume?

A. Data Progression will no longer work on the volume and the volume will no longer thin provisioned

B. Improved performance on the volume for a specific application and the RAID level of the volume will be changed to RAID 0

C. Data Progression will longer work on the volume and Ute RAID level of the volume will be changed to RAID 0

D. Improved performance on the volume for a specific application and the volume will no longer be thin provisioned

Correct Answer: A

Question 3

You need to configure a server that is connected to a Storage Center through iSCSI. You will need to use one or more hardware iSCSI host bus adapters. In addition, if connectivity is lost due to controller failover, the server needs to reconnect to the Storage Center iSCSI target ports.

D. ARP Redirect

Correct Answer: D

Question 4

A local SC Series storage array is replicating to a remote SC Series storage array. A problem occurs on the local array which causes you to failover to the remote array.

What is the reason for this Issue?

A. Replication restore points need to be validated

B. Remote SC Series array is still running

C. No replication QoS definitions exist

D. Local SC Series array is still running

Correct Answer: A

A. Ensure the servers are set up for multipagthing with Round Robin
Ensure all server iSCSI adapters are able to communicate with the storage.

B. Ensure Delayed Acknowledgment has been disabled on the iSCSI adapters.
Ensure all server iSCSI adapter are able to communicate with the storage.

C. Ensure the servers are set up for multipathing with Round Robin.
Ensure Deplayed Acknowledgment has been disabled on the iSCSI dapters.

D. Ensure the iSCSI adapters are set up for Jumbo Frames.
Ensure all server iSCSI adapters are able to communicate with the storage.

Correct Answer: D

Question 7

You are configuring a host to Boot from SAN through iSCSI. During the start of the boot process, the host times out when attempting to reach the volume and the boot fails. Which configuration setting action should occur to resolve this issue?
