Explanation

In Exchange 2000, Microsoft's best practice for multiple storage groups is to place each storage group's transaction log files on its own dedicated, separate physical drive. Transaction logs are written sequentially and continuously; giving them a dedicated spindle eliminates I/O contention with the database files and maximizes write throughput, directly improving performance. Keeping group A's logs on a separate drive from group B's logs also ensures that a disk failure affecting one storage group's logs does not impact the other group, improving availability and simplifying recovery. Placing both groups' transaction logs on the same drive (Option C) defeats this isolation. A mirrored volume for transaction logs (Option A) adds redundancy but is not the primary recommendation for logs because Exchange's own circular logging and log shipping provide recoverability; the dedicated, isolated drive is the higher-priority recommendation. Option D correctly reflects the Exchange 2000 guidance: a single dedicated drive per storage group for transaction logs, separate from the database (.edb/.stm) files.
