第2题：

While installing the equipment for a new two-node cluster， it is discovered that the disk subsystem  Rack has one connection to the power mains. The explanation given was that the disks are to be mirrored between the two disk drawers in the rack and that a failure in either of the disk drawers would simply result in half of the disk being lost.  What can be done to avoid a single point of failure？（）   

• A、 Customize HACMP to overcome quorum issues.
• B、 Add a second PDU to separate the power connections.
• C、 Use RAID5 when implementing two IO racks in a HACMP environment.
• D、 Add another shared disk to each volume group to avoid quorum issues during fallover.

第3题：

A two-node cluster is attached via SAN to shared disk. The customer has requested that one of  the nodes be moved to another room 300 feet away. However， this distance exceeds the length specified by the RS232 specifications.  What solution would resolve the RS232 specification issue with the fewest additional components？（）

• A、 Target mode fiber channel can be used with a SAN solution.
• B、 The heartbeat could be established by using a disk heartbeat.
• C、 An RS232 line driver can be used to extend the existing serial connection.
• D、 The NIM for the serial connection can be altered to compensate for the additional delay caused by the increased distance.

第4题：

During routine examination of the log files，a message similar to "TS_DMS_WRINING_ST" was discovered. To avoid future problems，change the Network Module failure detection rate to：（）

• A、 a faster value on the fastest heartbeat network.
• B、 a slower value on the slowest heartbeat network.
• C、 a faster value on the slowest heartbeat network.
• D、 a slower value on the fastest heartbeat network.

第5题：

Which of the following is required to ensure the completion of all tests within the automated procedure of thecluster test tool？（）

• A、Application monitoring has been configured
• B、Only disk heartbeat networks have been used
• C、Cluster nodes are attached to two IP networks
• D、Resource Group dependencies have been configured

第6题：

During implementation of a two-node cluster，it is determined that error notification for the shared Disk subsystem would be beneficial.  Which of the following is a pre-requisite for implementing automatic error notification？（）  

• A、 The cluster must not be running.
• B、 The cluster.es.server.utils lpp must be installed.
• C、 The error notification module must be enabled in RSCT.
• D、 The permissions on /tmp/hacmp.out need to be changed to 774.

第7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

第8题：

While adding the forced varyon volume group option， it is decided to create a disk heartbeat  Network over the disk paths. Which HACMP function is used to create disk heartbeat devices？（）

• A、 The Disk hearbeat facility is initialized when creating enhanced concurrent mode volume groups through HACMP.
