• A、 Multiple application servers must be in a single resource group.
• B、 Multiple application servers per resource group may be monitored.
• C、 Multiple resource groups must each contain a single application server.

第2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.

An administrator is evaluating an application for application monitoring. What command should be  Used to determine if the application can be monitored with a process monitor？（）  

• A、 pa aux
• B、 ps -el
• C、 ps -ef
• D、 ps -pl

第5题：

Company.com has installed HACMP and is configuring a three-node cluster. One of the Applications  uses the AIX hostname as a key for authorization to execute on the specific computer. The application vendor was contacted and consented to having multiple copies of the application but required that only one application be active at any one point in time.  How can the AIX host name dependency be managed in an HACMP environment.（）  

• A、 It cannot be managed because the application will not work properly with HACMP.
• B、 The application start and stop script for the application can manage the hostname.
• C、 HACMP will require customization to correctly manage a change in the hostname since it is tied to the primary network adapter.
• D、 HACMP will have to be restarted if the hostname is changed. This can be done with customization in the node_up and node_down event scripts.

第6题：

Which tool must be used to analyze all of the database operations performed by an application against a DB2 for i5/OS database?（）

• A、Visual Explain
• B、Activity Monitor
• C、SQL Performance Monitor
• D、DB2 Performance Monitor

第7题：

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？（）  

• A、 Only one application server per resource group can be monitored.
• B、 Process monitoring is part of RSCT and requires no special scripts.
• C、 Any application can be monitored as long as it has an application server.
• D、 Having all application servers in one resource group improves recovery time.

第9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.
