第1题：

A database administrator wants a unique IP address for each of three instances of a database.  Normally，all instances run on a large production node，but they may fallover to different standby nodes according to the dynamic node priority configuration.  What is the best way to obtain unique addresses for each of the three database instances？（）

• A、 There is no way since this cannot be configured with HACMP
• B、 Use IP Replacement address takeover and define all service addresses on the same NIC
• C、 Use IP Aliasing for address takeover and define each alias in a separate resource group
• D、 Use EtherChannel to map the three alias IP addresses to the common service address defined to HACMP

An enterprise has three nodes： -Node ’A’ is a production database， -Node ’B’ is a production  Application server， and -Node ’C’ is a test and development node. Node ’C’ is used by six programmers to develop and the production application as business critical and would like to make it highly available with HACMP. Application development and testing is not business critical.  Which of the following describes the best solution？（）  

• A、 There is not an adequate solution because HACMP should not be configured in this environment without a dedicated standby node.
• B、 Nodes ’A’ and ’B’ should be configured in a cluster with mutual fallover of two cascading resource groups to provide both nodes will deliver acceptable response time with both resource groups.
• C、 Nodes ’A’ and ’C’ should be configured in one cluster， and Nodes ’B’ and ’C’ in another cluster to prevent both the database and application server from falling over to Node ’C’ at the same time.

第6题：

During a cluster functionality test， and administrator performs a graceful stop for Node ’B’ in a three-node cluster. What is the expected state of the cluster after Node ’B’successfully completes？（）  

• A、 All cluster resources halt on Node ’B’，and one or both surviving nodes will gracefully acquire the resources.
• B、 All cluster processes halt on Node ’B’，the cluster resources remain active，and the remaining  nodes take no action.
