An HACMP cluster is planned for two logical partitions ……

An HACMP cluster is planned for two logical partitions on IBM p690 servers. Both partitions have three network interface adapters： two service adapters on a production network connected to an IP switch， and an administration adapter on a stand-alone hub that is connected to the p690 server’s HMC. Non-IP hearbeat paths cannot be configured due to the available hardware in the p690 servers.
Given the resources available，what is the best configuration for this cluster？（）

A. Add hardware to provide either serial heartbeats or shared disk heartbeats.
B. Define the administration network so HACMP will send heartb4eats over the non-routed network.
C. Add the administration network adapters to the production resource groups with IPAT via IP replacement selections.
D. Configure the IP Network Interface Module in HACMP with an increased heartbeat detection rate to prevent node isolation confutations.

单项选择题Whatmustbedonetomakeasharedtapedrivehighlyavailable？（）

A. Ensure the rmt numbers are unique per node.
B. Nothing，because HACMP manages the state of the tape drive.
C. Nothing，because highly available tape devices are not supported.
D. Ensure that the tape device is in a defined state after system startup.

单项选择题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.

单项选择题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.

A. include the hostname in the resource group definition.

单项选择题An enterprise has two nodes： -Node ’A’ runs a large relational database and ha six CPUs and 32GB of memory. -Node ’B’ is an application server with three CPU’s and 16GB of memory. During peak production periods， the CPU load for Node ’A’ is normally between 30% and 40%. For Node ’B’， the CPU load is 10% to 20% during peak production periods. Which of the following describes the best solution for an HACMP cluster？（）

A. Two cluster with two resource groups in a mutual takeover configuration.
B. One cluster with two cascading resource groups in a mutual takeover configuration.
C. One cluster with two rotating resource groups in a one-sided hot standby configuration.
D. Two clusters with two resource groups in a hot-standby configuration with a newly acquired third node.
