A. One disk per node，one networkB. Two disks per node，o……

During the initial cluster design，a disk heartbeat，Point-to-Point non-IP network is being planned as part of a three-node cluster implementation. The disk environment will use LVM mirroring for disk redundancy. The volume groups will be created as Enhanced Concurrent Capable.
To facilitate disk heartbeating，how many disks per node and how many networks will be required？（）

A. One disk per node，one network
B. Two disks per node，one network
C. Two disks per node，six networks
D. Two disks per node，three networks

单项选择题Company.com has two sites that are 3072 kilometers apart and wants to implement HACMP between eh two locations. The nodes at each location must be capable of running the application in the event of a failure. Currently the customer’s disk technology is SCSI. How can HACMP be used in this environment？（）

A. HACMP cannot span sites； the environment must be contained in a single site.
B. HACMP/XD：HAGeo has unlimited distance mirroring that may be appropriate for this environment.
C. HACMP cannot be split into two sites that exceed the limitation s of the storage cable length.
D. HACMP/XD：PPRC that is included with the base HACMP distribution will enable site-to-site communications in HACMP.

单项选择题During Company.com planning session，Company.com presents the details of the current Network design. The network design serves four separate company facilities， each on as separate subnet. As part of a disaster recovery plan， the customer is evaluating the use of HACMP. Specifically， the have reviewed IPAT via IP aliasing and are questioning the number of IP subnets required. Given the customer’s current configuration，what is the recommended minimum number of IP subnets that would be required？（）

A. 4
B. 5
C. 6
D. 8

单项选择题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.
