单项选择题An enterprise has two nodes： -Node ’A’ runs a large relational database and ha six CPUs and  32GB of memory. -Node ’B’ is an application server with three CPU’s and 16GB of memory. During peak production periods， the CPU load for Node ’A’ is normally between 30% and 40%. For Node ’B’， the CPU load is 10% to 20% during peak production periods.  Which of the following describes the best solution for an HACMP cluster？（）

A. Two cluster with two resource groups in a mutual takeover configuration.
B. One cluster with two cascading resource groups in a mutual takeover configuration.
C. One cluster with two rotating resource groups in a one-sided hot standby configuration.
D. Two clusters with two resource groups in a hot-standby configuration with a newly acquired third node.

单项选择题Company.com has a three-node cluster （Node ’A’， Node ’B’， and Node ’C’） with three resource  Groups （rg1， rg2， and rg3）. Node ’A’ has twice as many CPUs and twice as much memory as the two test add development Nodes ’B’ and ’C’. During normal production processing， all resource groups are active on Node ’A’.  What is most efficient way to configure the cluster to manage the workload？（）

A. Use thee cascading resource groups where ’rg1’ and ’rg2’ fallover to Node ’B’ and ’rg3’ falls over to Node ’C’
B. Use Dynamic Node Priority resource groups with a priority chain consisting of Node ’A’ then Node ’B’ then Node ’C’
C. Use three rotating resource groups with ’rg1’ and ’rg2’ falling over to node ’B’ and ’rg3’ falling over to Node ’C’
D. Upgrade Nodes ’B’ and ’C’ to be equal to Node ’A in CPU and memory resources to enable the cluster to synchronize three resource groups

A. Nothing， the "Recover From Script Failure" will correct the issue.
B. Disable and re-enable the effected Ethernet adapter by using ifconfig.
C. Correct the error by setting the hostname on the effected node from the command line.
D. Verify that the clinfo daemon is running prior to executing the "recover from scriptfailure".

单项选择题A recommended PTF is released to resolve reliability issues with bos .net.tcp.server. A Maintenance windows has been scheduled to install the PTF on all nodes.  In order to complete the maintenance，what are the next logical steps to be completed after the install of the PTF on all nodes？（）

A. Test Ethernet fallover and bring all of the resource groups online.
B. Upgrade the firmware on all Ethernet adapters and bring all of the resource groups online. 
C. Verify all necessary applications and resource groups are functioning properly and test ethernet fallover on all nodes.
D. Verify all necessary applications and resource groups are functioning properly and bring all of the resource groups online.
