Company.com is considering converting from IPAT via replacement to IPAT via IP aliasing. What condition of IPAT via IP aliasing must be taken into consideration？（）

单项选择题Company.com has a four-node cluster （nodes ’A’， ’B’， ’C’， and ’D’）. The nodes are set up in  Resource group pairs. Node ’A’ falls over to Node ’B’， and Node ’C’ falls over to Node ’C’. During a maintenance windows， it was discovered that the six resource groups on Node ’A’ are too much to be adequately handled by Node ’B’.  What could be done to better utilize the available resources during fallover？（）

A. Implement Work Load manager so that the application monitors for additional resource      requirements.
B. Add a fifth node to function as a load leveler in order to control the dispatching of the resource jobs.
C. Implement Dynamic Node Priorities in the resource groups in order to find a node with suitable system resources.
D. Reduce the number of resource groups on Node ’A’ to 1 in order to ensure faster and more robust fallover to a single system.

A. Disk should be mirrored across separate storage enclosures.
B. Disk heartbeats should be added over multiple disk adapters.
C. Disk major and minor numbers should be set as unique across nodes.
D. Disk adapter queue_depth should be increased from the default values.
