B. Create two EVSs and use DNS aliasing to represent the four names and four IP addresses.

C. Create four individual EVSs representing the four servers.

D. Create four individual EVSs, two on each node and use QoS to balance the load.

A. Intelligent Data Replication at the file system level

B. Intelligent Data Replication at the storage pool level

C. Incremental Block Replication at the storage pool level

D. Intelligent Data Replication at the virtual volume level

E. Incremental Block Replication at the file system level

A customer is running Web messaging related applications using a Hitachi NAS Platform 3080.

A. multiple Checkpoints

B. quick rollback to a previous successful snapshot

C. data recovery from the deleted file system

D. the "consistency-check" command

A customer is asking for a detailed description of clustering technology on the Hitachi NAS Platform cluster with multiple GbE ports in the aggregates. Which two statements describe the automatic failover behavior? (Choose two.)

A. Only the EVS affected by a problem will failover to another node.

B. All EVS will failover when a GbE port in an aggregation fails.

C. An EVS will failover when all GbE ports in an aggregation used by an EVS fail.

D. An EVS will not failover when all GbE ports used by an EVS fail.
