During initial cluster planning session， a requirement is mandated that application monitoring will  Be used to monitor the production database and three application servers. Since all the application servers rely on the database being active， only one resource group has been planned to manage the starting/stopping of the cluster resources. 
How ill the initial design impact the use of application monitoring？（）  

单项选择题To enhance the availability of an application running under HACMP， a decision was made to use  The application monitoring facility. The application consists of several components and can take several minutes to initialize. The components use socket communication and can be initialized in any order as long as it is a serial order. The customer’s concern is that if the application stop and start scripts are used during application monitoring recovery，it may take an extraordinary length of time to reset all of the application components.  What can be done to ensure the best recover time？（）

A. Use a process monitor that restarts the named processes in the original start order.
B. Use the defined application start and stop scripts to control the application if there is a failure.
C. Use multiple application monitors for this resource group to enable the monitoring of the specific components of the resource group.
D. Use application cleanup and restart scripts designed to determine the state of the various components of the application and start only the parts required.

A. Two cluster with two resource groups in a mutual takeover configuration.
B. One cluster with two cascading resource groups in a mutual takeover configuration.
C. One cluster with two rotating resource groups in a one-sided hot standby configuration.
D. Two clusters with two resource groups in a hot-standby configuration with a newly acquired third node.

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
