第4题：

Company.com is migrating from a third party managed disk subsystem to an IBM TotalStorage Enterprise Storage Server. Connection of the new storage server is complete， and it has been tested on all of the nodes in the three node HACMP cluster.  How does the customer migrate to the new storage server with minimum down time？（）

• A、 Shut down one node at a time and let the other node serve the application

• C、 Stop both nodes and perform the migration all at once using standard AIX commands in parallel， then restart the cluster
• D、 Use C-SPOC to add the new disks to the cluster and migrate the information off the existing disks， then remove the old disks with C-SPOC

第5题：

A cluster node has been started and has not acquired the resources in the resource groups.  Which log file will show the details of any event script processing that has occurred？（）  

• A、 /tmp/hacmp.out
• B、 /tmp/clstrmgr.debug
• C、 /usr/es/adm/cluster.log
• D、 /var/adm/hacmp/hacmp.out

第6题：

An administrator has added an additional network adapter to each cluster node. The adapters  have been configured and tested， and the /etc/hosts file has been updated. However，the adapters do not appear in the pick list when the administrator tries to define the adapters to HACMP.  What would be required to correct this problem？（）  

• A、 Rerun autodiscovery.
• B、 Synchronize the cluster.
• C、 Restart cluster services.
• D、 Delete and recreate the adapters.

第7题：

A new administrator is performing fallover testing on a two-node cluster and is concerned that the cascading resource group belonging to Node ’A’ did not reintegrate properly after the cluster was restarted on Node ’A’. A stable cluster is reported by clstat，and clRGinfo reports the resource group online on Node ’B’.  What type of configuration would cause this type of behavior？（）  

• A、 The resource group DNP has been configured.
• B、 The resource group option CWOF has been enabled.
• C、 The resource group option Inactive Takeover is set.
• D、 A resource group fallback timer has been configured.

第8题：

A new HACMP maintenance level has recently been released. An administrator is creating a  project plan that is required for applying the updates for a three-node production cluster.  To minimize downtime，what is the best way to accomplish the updates on all cluster nodes？（）  

• A、 Perform a graceful takeover one node at a time and apply the updates.
• B、 Perform the updates on all nodes simultaneously using C-SPOC utilities.
• C、 Perform the updates on node at a time with the cluster software active.
• D、 Perform a graceful stop of all cluster nodes and apply updates to all nodes.

第9题：

Company.com has installed HACMP and is configuring a three-node cluster. One of the Applications  uses the AIX hostname as a key for authorization to execute on the specific computer. The application vendor was contacted and consented to having multiple copies of the application but required that only one application be active at any one point in time.  How can the AIX host name dependency be managed in an HACMP environment.（）  

• A、 It cannot be managed because the application will not work properly with HACMP.
• B、 The application start and stop script for the application can manage the hostname.
• C、 HACMP will require customization to correctly manage a change in the hostname since it is tied to the primary network adapter.
• D、 HACMP will have to be restarted if the hostname is changed. This can be done with customization in the node_up and node_down event scripts.

第10题：

A HACMP/XD://HAGeo cluster has been installed with four nodes， two nodes at each site. The cluster is protected from site isolation by the DBFS facility in HACMP/XD://HAGeo.  In the event of a site failure，what happens？（）  

• A、 The dominate site will always assume the non-dominate site has failed and continue processing.
• B、 The dominate site initiates a call to the non-dominate site to verify if any of the nodes are functional.
• C、 The non-dominate site initiates a call to the dominate site to verify if any of the nodes are functional.
• D、 The nodes are completely independent and can call each other if they detect a total failure of the ZGeo_Primary network.
