第1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2题：

A highly available WebLogic cluster in UNIX is configured for automatic server migration. Node Managed is configured on both machines to start managed servers. How should you simulate a managed server failure to test whether automatic server migration is working?（）

• A、Shut down the managed server from the WebLogic console.
• B、Shut down the managed server using the WLST command through Node Manager.
• C、Run "kill -9" once to kill the managed server process.
• D、Run "kill -9" to kill the managed server process, and run "kill -9" one more time if the managed  server is restarting.

第3题：

When your WebLogic Server solution needs to be scaled out with additional capacity and you  Don’t want to add additional hardware, which three techniques should you us?（）

• A、Assign more than one managed server to a physical hardware that allows better CPU  utilization
• B、Assign more than one application to one managed server to better utilize threads within a single JVM process
• C、Assign the same application to more than one managed server to load balance requests  between servers
• D、Assign the same heap size to the managed server across the cluster for easier control of  memory footprint  
• E、Create a virtualized environment with hypervisor for an easier solution

第4题：

第5题：

How can an Oracle WebLogic cluster’s capacity be increased ？（）

• B、 by adding machines to host server for more clustered instances
• C、 by adding machines to the cluster to host the incremental server instances
• D、 by adding node managers to an existing machine

第6题：

Company.com is migrating from a third party managed disk subsystem to an IBM TotalStorage Enterprise Storage Server. Connection of the new storage server is complete， and it has been tested on all of the nodes in the three node HACMP cluster.  How does the customer migrate to the new storage server with minimum down time？（）

• A、 Shut down one node at a time and let the other node serve the application
• B、 Stop HACMP with the forced option and perform migration of the disks on one node，then restart HACMP
• C、 Stop both nodes and perform the migration all at once using standard AIX commands in parallel， then restart the cluster
• D、 Use C-SPOC to add the new disks to the cluster and migrate the information off the existing disks， then remove the old disks with C-SPOC
