An enterprise has two nodes： -Node ’A’ runs a large relational database and ha six CPUs and  32GB of memory. -Node ’B’ is an application server with three CPU’s and 16GB of memory. During peak production periods， the CPU load for Node ’A’ is normally between 30% and 40%. For Node ’B’， the CPU load is 10% to 20% during peak production periods. 
Which of the following describes the best solution for an HACMP cluster？（）  

单项选择题Company.com has a three-node cluster （Node ’A’， Node ’B’， and Node ’C’） with three resource  Groups （rg1， rg2， and rg3）. Node ’A’ has twice as many CPUs and twice as much memory as the two test add development Nodes ’B’ and ’C’. During normal production processing， all resource groups are active on Node ’A’.  What is most efficient way to configure the cluster to manage the workload？（）

A. Use thee cascading resource groups where ’rg1’ and ’rg2’ fallover to Node ’B’ and ’rg3’ falls over to Node ’C’
B. Use Dynamic Node Priority resource groups with a priority chain consisting of Node ’A’ then Node ’B’ then Node ’C’
C. Use three rotating resource groups with ’rg1’ and ’rg2’ falling over to node ’B’ and ’rg3’ falling over to Node ’C’
D. Upgrade Nodes ’B’ and ’C’ to be equal to Node ’A in CPU and memory resources to enable the cluster to synchronize three resource groups

单项选择题Company.com has a three-node cluster with six resource groups. There are two resource groups  for each node. A new hardware component will be added to one of the nodes. The customer wants to move the resource groups to other nodes，but not necessarily in the normal fallover order. Also，the resource groups must be moved at night when there is no one in the computer center. What can be done so that the resource group is moved at the most convenient normal fallover order. Also，the resource groups must be moved at night when there is no one in the computer center.  What can be done so that the resource group is moved at the most convenient time for the customer？（）

A. Create a custom resource group with a custom fallback timer to cause the system shutdown at he appropriate time.
B. Set the system to stop with "shutdown" command at the appropriate time and allow HACMP to relocate the resources.
C. Use a script that calls the cIRGmove command and place it in the cron or a queue to execute at the appropriate time.
D. Change the existing resource groups to a custom type and add a timer to perform a "shutdown -h" command at the appropriate time.
