第2题：

A customer has 5 older POWER5 systems and they want to consolidate them onto a POWER6 system. What information is important to analyze when deciding how to design the new machine using the System Planning Tool?（）

• B、 The number of CPUs that were installed in the original machines 
• C、 Data from Workload Estimator (WLE) and IBM Performance Management (PM) 
• D、 Performance data that is collected from the new system after it has been put into production

第3题：

During a planning session， the customer indicates the need to provide high availability between a  Node attached to an IBM TotalStorage Enterprise Storage Server and a remote node attached to a IBM TotalStorage FAStT server with automatic fallover in the event of a disaster.  Which of the following HACMP options will provide this functionality？（）  

• A、 GeoRM
• B、 HACMP/XD://PPRC
• C、 HACMP/XD://GPFS
• D、 HACMP/XD://HAGEO

第4题：

During an HACMP migration，two nodes of a four-node cluster have been migrated. The existing hardware of the remaining two nodes do not meet the pre-requisites of the HACMP level that is being installed.  Which of the following is the best method for resolving this issue？（）

• A、 Upgrade the unsupported hardware and continue with the migration.
• B、 Restore the two nodes that have been migrated with a cluster snapshot.
• C、 Restore the two nodes that have not been migrated with a cluster snapshot.
• D、 Synchronize the cluster to allow the nodes that didn’t migrate to join the cluster.

During Company.com planning session， the LVM requirements for HACMP are provided. The administrator explains that there are five volume groups in the current production environment because filesystems constantly change due to the nature of the business. Maintenance outages are limited to one Saturday per month. There is some concern about the amount of time that will be required for outages once HACMP is installed.  With HACMP，what will be the simplest methods of managing LVM changes while minimizing required downtime.（）  

• A、 Make changes and allows Lazy Update to sync the changes later.
• B、 Use the Cluster Single Point Of Control to manage LVM changes.
• C、 Use exportvg on the primary node and improtvg on the second node.
• D、 Set up a local NFS cross-mount， and use the local filesystem until the outage.

第14题：

During a planning session， it is determined that a three node cluster （Node ’A’， Node ’B’， and Node ’C’） will meet the customer’s application needs. Node ’B’ will be a hot-standby fallover node for both Node ’A’ and Node ’C’ resource groups.  A serial network for this cluster will require which connections？（）  

• A、 A single serial network between Node ’A’ and Node ’B’ and Node ’C’
• B、 A point-to-point link between Node ’A’ and Node ’C’，and Node ’B’ and Node ’C’
• C、 A serial network between Node ’A’ and Node ’C’，and a serial network between Node ’B’ and Node ’C’
• D、 A point-to-point link between Node ’A’ and Node ’B’ Node ’B’ and Node ’C’ and Node ’A’ ad Node ’C’

During an internal IT organization planning session， it is decided that a new cluster node would  Enhance the performance of a distributed corporate application. Planning details have been assigned to the administrator. System outages are limited to one weekend per month； therefore， availability will be a key issue in the planning process.  How much cluster downtime will need to be allocated for adding a new node？（）  

• A、 None，everything can be done with the cluster active.
• B、 Minimal downtime will be required to import the volume groups.
• C、 Several hours are required for testing before final synchronization.
• D、 Minimal downtime will be required to connect and test the serial network.

第16题：

During Company.com planning session， the discussion focuses on how the IP connections are  Managed after a cluster node failure. This is critical for the business since their production application is a Lotus Domino solution requiring multiple IP addresses and recovery time is critical.  What type of IPAT implementation would best address these requirements？（）
