An administrator runs clstat on a cluster node and receives the following response： ’Can not get  Cluster Information.’ Which of the following daemons may need to be started in order to correct this problem？（）

单项选择题During a cluster synchronization， an administrator inadvertently performs al ctrl ’C’ causing the synchronization to fail. After restarting the resynchronization， the administrator notices a message stating that a previous dare operation has been detected.  What is the best way to resolve this problem？（）

A. Perform a ’Recover from HACMP Script Failure’.
B. Perform a ’Release Lock Set By Dynamic Reconfiguration’.
C. Perform a graceful stop an& start of all cluster processing.
D. Perform a ’Restore HACMP Configuration Database from Active Configuration’.

单项选择题When the clverify utility is run，verification checks use ODM data provided by the common communication infrastructure. This provides efficient access to configuration ODMs from the other nodes. The utility manages these files by storing the copies in various directories depending on the success or failure of the verification pass.  By default，this directory is  var hacmp clverify current nodename  if the ’current’ directory still exists when clverify stops running，this indicates which of the following？（）

A. A successful completion of clverify
B. A problem with the clverify utility
C. All nodes agree on active configuration
D. Configuration differences between current and last successful clverify

单项选择题Theuserbaseofathree-nodeclusterhasincreased.Inordertoaddclustereduserstoallnodes，whichofthefollowingstepsshouldbeperformed？（）

A. On one of the nodes，add the users via C-SPOC ’Add a User to the Cluster’smit menu.
B. Use C-SPOC to synchronize the password files between cluster nodes.
C. On all of the nodes，add the users to the /etc/passwd and system security files，and then synchronize the cluster.
D. On one of the nodes，add the users to the /tec/passwd and system security files，add home directories，and use cron to automate the movement of system security files between nodes.

单项选择题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.

单项选择题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.
