单项选择题
Company.com has a resource group that contains a database that is accessed by a web client based on another system. The communication to the database is TCP/IP. Occasionally after a failure， the end users get unusual error messages that indicate the database server is not available. It has been determined that the web server is trying to access the database server’s information before it has completed file system recovery after a failure. How can HACMP affect this problem？（）
A. HACMP can resequence the order to the starting of the various resource group elements by utilizing Dynamic Node Priority.
B. The order of dependency can be controlled though the HACMP resource group configuration if the web server was made to be part of the HACMP cluster.
