第1题：

On an existing two-node cluster， the system is configured with RAID5 SSA as the shared disk.  When adding a new node to the cluster， what must be taken into consideration？（）

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：

During normal cluster processing in a five-node cluster，one of the nodes unexpectedly crashes. A review of the system dump indicates that a DMS timeout has occurred. The cluster is configured to use disk heartbeats as a Point-to-Point network.  What should be done to address the problem with this configuration？（）  

• A、 More disk should be added to the disk heartbeat network，allowing more paths for heartbeats.
• B、 An RS232 network is required to supply a more robust non-IP network when disk heartbeating is implemented.
• C、 The network tunable parameters should be changed to allow more missed heartbeats since the disks may be heavily used.
• D、 An error notification method is required to determine the action to take in response to a failure of the disk heartbeat.

第4题：

Automatic error notification can be configured to manage which type of disk error？（）  

• A、 Hard errors
• B、 Media errors
• C、 Temporary errors
• D、 All disk error types

第5题：

An administrator has a 2 node cluster running PowerHA version 5.5. They remove a resource group from theactive cluster configuration. When performing a verify and synchronize of the cluster， the administrator getsthe following error： "migcheck[471]： cl_connect（） error， nodename=Node1， rc=-1 cldare： A communication error prevents obtaining the VRMF from remote nodes. A DARE event cannot be run until this is corrected. Please ensureclcomd is running." What is the most likely cause of this error？（）

• A、There is a DARE lock in place
• B、A PowerHA migration is in progress
• C、Cluster services is not active on the other node
• D、The other cluster node is running a different version of RSCT

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：

An administrator is configuring a new cluster and has a requirement for a notification to be generated if the /tmp File System becomes greater than 90% full. Which of the following PowerHA components will support theadministrator’s requirement？（）

• A、Pre-defined Events
• B、User-defined Events
• C、Remote notification methods
• D、The integration between RMC and WebSM

第8题：

A cluster administrator has defined a custom error notification method that will email and  administrator when a temp error is detected on an individual hdisk. What method should be used to test this functionality？（）  

• A、 sendmail -bi
