第1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

第2题：

A cluster using IPAT via IP aliasing has four adapters. Normally there are several resource  groups that have a total of four service IP labels. When two of the adapters fail， what happens？（）  

• A、 The resource group containing the IP labels changes to an "offline" state.
• B、 The IP service labels of the failed adapters relocate the surviving adapters.
• C、 Nothing because the resource groups wait for the adapters to become active again.
• D、 The resource groups containing the IP labels of the failed adapters migrate to a backup node.

第3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4题：

A cluster node has three network interfaces that support three resource groups with three service  IP labels. Each IP label uses IPAT via IP aliasing. One of the adapters fails， and all of the IP labels on it are moved to other interfaces as expected. The system supports the "hot swap" replacement of the network interfaces， and the system engineer has corrected the problem.  What will happen to the service IP lab3els when the repaired adapter is noticed by HACMP？（）

• A、 They will migrate back to the repaired interface.
• B、 They will not move，the interface will join the pool of available resources.
• C、 They will not move； the interface will join the cluster as an available non-service adapter. 
• D、 They will migrate to the repaired interface to create an equal number of service IP labels per interface.

A pSeries technical specialist is configuring the network adapters for an HACMP cluster.  The plan is to use a four-port Ethernet adapter with IPAT via IP aliasing for the two service IP labels.  Which of the following would be a critical concern with the proposed configuration？（）

• A、A four-port adapter is not supported.
• B、The four-port adapter is a single point of failure.
• C、There should be a spare port for each service IP label.
• D、The four-port adapter could be a potential performance bottleneck.

第6题：
