Which statement is true about using Microsoft Windows Cluster as a platform for MySQL?
The correct answer is A. It relies on the shared disk architecture being visible to both servers. Microsoft Windows Server Failover Clustering uses a shared disk architecture, where both cluster nodes have visibility to the same physical storage (typically a SAN), but only the active node accesses it at any given time - when that node fails, the passive node takes over…

Explanation
Microsoft Windows Server Failover Clustering uses a shared disk architecture, where both cluster nodes have visibility to the same physical storage (typically a SAN), but only the active node accesses it at any given time - when that node fails, the passive node takes over using the same shared disk. This is precisely what option A describes.
Why the distractors are wrong:
- B describes DRBD-style IP-level block replication, which is a Linux-based HA solution (not Windows Cluster), and is actually closer to how MySQL Replication or DRBD works.
- C confuses two unrelated features - the .NET Connector's load balancing is a client-side connection feature and plays no role in cluster-level High Availability.
- D describes MySQL NDB Cluster, which genuinely is a shared-nothing architecture - this is the most common trap, since "MySQL Cluster" and "Windows Cluster for MySQL" sound similar but are fundamentally different technologies.
Memory tip: Pair the opposites - Windows Failover Cluster = shared disk; MySQL NDB Cluster = shared nothing. If you remember that one pair, you can eliminate both B and C as irrelevant mechanisms, leaving A as the only accurate description.
