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？（）

第3题：

Continuous availability is required for an application in a two-node cluster. There is one rotating resource group in the cluster， and the nodes are identical machines. Client telnet connections to the application cannot be broken because it takes 20 to 30 minutes to recycle the client workstations and transactions will be lost.  What configuration best provides continuous connectivity to the application？（）   

• A、 IPAT using IP Replacement without MAC address takeover.

第5题：

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：

A cluster with 10 adapters per node is converted to use IPAT address takeover vial IP aliasing.  During the conversion， the customer ran out of IP subnets in the allocated range.  What feature in HACMP can help resolve this issue？（）  

• A、 Disk based heartbeats
• B、 Heart beating via IP aliasing
• C、 IP aliases for the non-service addresses
• D、 A single subnet for all non-standby adapters

第7题：

Which of the following statements is true about IPAT via IP replacement？（）  

• A、 Configuration of Hardware Address Takeover is supported.
• B、 Fewer physical network interface cards are required in the cluster.
• C、 It is the default for keeping a service IP labels highly available.
• D、 None-service ip labels must use different subnets than service IP labels.

第8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.

A two-node cluster is configured for mutual takeover with two service IP labels. The cluster is Being tested for fallover behavior. Both nodes in the cluster have two network interfaces （ent0’ and ’ent1’） configured with IPAT via IP Replacement. When the network cable is removed from the interface card with the service address （’ent0’）， the service address is moved to ’ent1’， and ’ent0’ is reconfigured on its boot address. When the network cable is replaced on ’ent0，the service address does not switch back to ’ent0’.  What statement most accurately describes this situation？（）   

• A、 EtherChannel is needed to automatically switch the service IP address back to ’ent0’.
• B、 This is the default behavior for a network interface failure with this configuration.
• C、 Gratuitous ARP support needs to be enabled for the IP Network Interface Module in SMIT.
• D、 The Inactive Network Takeover option should be set to "true" to forece the service address back to ’ent0’.
