A new HACMP maintenance level has recently been released. An administrator is creating a  project plan that is required for applying the updates for a three-node production cluster. 
To minimize downtime，what is the best way to accomplish the updates on all cluster nodes？（）  

单项选择题While reviewing the HACMP log file， a warning message appears stating that a custom event script could not be found. A check of the current path settings indicates that all required paths are present.  What step can be taken to correct the missing paths issues during cluster event processing？（）

A. Move the custom script to a different location such as /usr/sbin.
B. Include required paths at the start of the custom script.
C. Synchronize and verify the cluster to ensure both nodes are the same.
D. Create a pre event that sets the correct paths and executes the script.

单项选择题In the past several months， manual intervention has been required to correct improper cluster configuration changes. The administrator received a directive from management to create a more effective strategy for making the changes required fro month-end processing.  How can HACMP be used to meet the requirements of management’s directive？（）

A. Create a snapshot for each of the required cluster configurations.
B. Create a custom snapshot method to handle the configuration changes.
C. Create a custom verification method to verify configuration changes.
D. Create a cluster custom event to mange required configuration changes.
