IBM(000-237)單項(xiàng)選擇題每日一練(2019.01.10)

Company.com has a resource group that contains a database that is accessed by a web client  based on another system. The communication to the database is TCP/IP. Occasionally after a failure， the end users get unusual error messages that indicate the database server is not available. It has been determined that the web server is trying to access the database server’s information before it has completed file system recovery after a failure. 
How can HACMP affect this problem？（）   

A node in a three-node cluster was started， ad it acquired the following three cascading resourcegroups： 
’rg1’， ’rg12’， and ’rg3’. The cluster design is to have ’rg1’ normally Node ’A’， ’rg2’ normally on Node ’B’， and rg3’ normally on Node ’C’. 
How can the administrator reposition the resource groups and correct the problem？（）  

Company.com is adding HACMP to an existing pair of nodes. One node is using EtherChannel  with only one adapter. The other node is using regular Ethernet connection to the switch. The customer is going to increase the number of network interfaces to two for each node. 
What other considerations need to be addressed in a HACMP environment？（）
