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. A SQL Server 2008 instance is managed by you. A new database should be deployed, and the capacity requirements listed below should be satisfied. There should be 275 GB for the database data file, while there should be 50 GB for the transaction log file. There are six 100-GB disk drives which are accessible for the database in the storage array. The six disks are attached to a redundant array of independent disks (RAID) controller, and the controller supports RAID levels 0, 1, 5, and 10. Since you are the technical support, you are required to maximize the write performance of the transaction log. In addition, you should protect the database and transaction log files, when a drive fails. The storage system should be designed. From the following four storage configuration, which one should you utilize?()A、A single RAID 5 volume should be utilized. B、A RAID 1 volume and a RAID 5 volume should be utilized.C、A single RAID 10 volume should be utilized. D、A RAID 0 volume and a RAID 5 volume should be utilized.
