A
Increase the number of NFS daemons for increased performance.
B
Modify the nfsrg1 resource group to use local NFS cross-mounts.

考题
A step in the HACMP test plan is to gracefully stop the cluster on a node and to verify that the Shared resources fallover to the standby node. To prepare for this testing step， both nodes in the two-node cluster are in a stable state with the single resource group active on Node ’A’.

考题
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.

考题
As part of fallover testing of a corporate database server， client application connectivity must be verified. Which of the following would best verify the application functionality？（） A、 Perform a ping client verification test.B、 Review the number of active application processes.C、 Perform successful reads and writes to the application.D、 Run netstat -an to verify client connections to the listening ports.
考题
A two-node cluster provides NFS exports to a variety of UNIX clients. During fallover testing，it is determined that some clients are unable to mount the exported filesystems after fallover，and before node reintegration. It is verified that the filesystems belong to a resource group and are correct in /usr/es/sbin/cluster/etc/exports. Which of the following may provide a possible solution to this problem？（） A、 Use HWAT for IPAT to provide more reliable NFS serving.B、 Use AIX Fast Connect to provide more robust NFS serving.C、 Use NFS Cross Mounting to allow both nodes to export NFS properly.D、 Use the "Filesystem Mounted before IP Configured" flag to provide more predictable NFS serving.
