You are a professional level SQL Sever 2008 Database Administrator in an international corporation named Wiikigo. You are experienced in managing databases in an enterprise-level organization, optimizing and sustaining the database life cycle. In the company, your job is to implement solutions on security, troubleshooting, deployment and optimization. SQL Server 2008 servers on a single site are managed by you. Two SQL Server 2008 instances are contained by the site. One is an Enterprise Edition server, and it is on a server that has a redundant array of ndependent disks (RAID) 10 disk system. The other is a Standard Edition server, and it is on a server that has a RAID 5 disk system. A single application is hosted by each instance. A high-availability solution should be recommended for the site to satisfy the business requirements listed below. First, the solution can be implemented on the current systems. Secondly, the database is available with least downtime. Thirdly, Data loss should be cut to the least. Fourthly, the existing system should be with least impact. Which solutions should be utilized to finish the task?（）A、To finish the task, Log shipping should be utilized. B、To finish the task, Failover clustering should be utilized.C、To finish the task, Replication should be utilized. D、To finish the task, Database snapshot should be utilized.
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.

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.D、 Nodes ’A’， ’B’， and ’C’ should be configured in a cluster with Node ’C’ the hot standby for both the database and application server resource groups. Workload Manager （WLM） must be configured on database and application developers from over utilizing the CPU resources.
