第1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.

第5题：

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？（）

• D、 Two disks per node，three networks

第6题：

Company.com is planning for an HACMP cluster and wants to know more about the network requirements. The plan is to use IPAT via IP aliasing and heartbeating via IP aliasing to preserve the corporate IP addresses. Currently the customer uses a separate VLAN for each individual subnet.  Which statement best describes how HACMP co-exists with VLAN’s in this configuration？（）   

• A、 All subnets in use by HACMP must be in the same VLAN.

第8题：

A database administrator wants a unique IP address for each of three instances of a database.  Normally，all instances run on a large production node，but they may fallover to different standby nodes according to the dynamic node priority configuration.  What is the best way to obtain unique addresses for each of the three database instances？（）
