• 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2题：

During Company.com planning session， the network administrator discusses the requirements of having a persistent MAC address associated with the IP Service address.  How can this be accomplished using HACMP？（）

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：

One service IP label and one volume group are assigned to a resource group in a cluster. An  Additional service IP label and volume group need to be added to the resource group.  How can this be done with the minimum disruption of the cluster？（）  

• A、 Make the changes in HACMP and synchronize the cluster.
• B、 It cannot， because changes like this cannot be made while the cluster is running.
• C、 Make the changes in HACMP and wait until the next failure for the changes to take affect.
• D、 Use the forced option to stop the cluster，make the changes，and restart cluster services.

第5题：

Defining an HACMP cluster using the Initialization and Standard Configuration menu is limited to the use of：（）  

• A、 IPAT via IP aliasing
• B、 Custom Resource Groups
• C、 Heartbeating over IP Aliases
• D、 Concurrent Capable Volume Groups

第6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？（）  

• 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

• C、 Volume Groups using raw logical volumes
• D、 Volume Groups supporting concurrent access

第8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.
• B、 All subnets in sue by HACMP must be in a different VLAN.
• C、 HACMP does not support multiple subnets when using heartbeating via IP aliasing.
• D、 HACMP does not support the use of VLAN.

第9题：

• A、 The Volume Groups must be changed with chvg -E vgname.
• B、 The Volume Groups must be a member of a resource group and must be varied on al nodes of       the cluster.
• C、 The Volume Groups must be a member of a resource group and must be varied off all nodes      of the cluster.
• D、 The Volume Grups cannot be changed to enhanced concurrent capable because they must be      recreated with mkvg -C vgname.
