第3题：

An enterprise has three nodes： -Node ’A’ is a production database， -Node ’B’ is a production  Application server， and -Node ’C’ is a test and development node. Node ’C’ is used by six programmers to develop and the production application as business critical and would like to make it highly available with HACMP. Application development and testing is not business critical.  Which of the following describes the best solution？（）  

• A、 There is not an adequate solution because HACMP should not be configured in this environment without a dedicated standby node.
• B、 Nodes ’A’ and ’B’ should be configured in a cluster with mutual fallover of two cascading resource groups to provide both nodes will deliver acceptable response time with both resource groups.
• C、 Nodes ’A’ and ’C’ should be configured in one cluster， and Nodes ’B’ and ’C’ in another cluster to prevent both the database and application server from falling over to Node ’C’ at the same time.
• D、 Nodes ’A’， ’B’， and ’C’ should be configured in a cluster with Node ’C’ the hot standby for both the database and application server resource groups. Workload Manager （WLM） must be configured on database and application developers from over utilizing the CPU resources.

第4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.
• C、 HACMP can delay making the network label available until after the filesystem checks have completed with the "filesystem mounted before IP is configured".
• D、 The IP service label can be in a second resource group allowing the sequential processing of resource groups to control when the IP service label is made available.

• A、archival
• B、log writer
• C、database writer
• D、system monitor
• E、process monitor
• F、change tracking writer
