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？（）

单项选择题An administrator has made several topology and resource group changes on one node in a running cluster.During verification and synchronization， using the  Emulate  option， many errors are reported. Theadministrator decided the best course of action was to roll back the changes. Prior to the changes beingmade， a cluster snapshot was taken. Which of the following actions will roll back the changes with the least disruption？（）

A.Perform a synchronization from a node without the changes.
B.Apply the cluster snapshot on both nodes while the cluster is running.
C."Restore HACMP Configuration Database from Active Configuration" on the node where the changes weremade
D.Stop the cluster using the option "Unmanage Resource Groups" and apply the cluster snapshot on thenode where the changes were made
