Cluster1 is a failover cluster with 6 nodes, dynamic quorum, and a file-share witness using dynamic witness. What is the maximum number of node failures the cluster can tolerate while still maintaining quorum?

A failover cluster with 6 nodes and dynamic quorum can tolerate a certain number of failures while maintaining quorum. Dynamic quorum automatically adjusts the quorum vote based on the number of active nodes. With a file-share witness using dynamic witness, the witness only gets a vote if there's an even number of nodes, preventing a tie. In this scenario, with 6 nodes, the cluster needs 4 votes to maintain quorum (6 nodes / 2 + 1 = 4). If 1 node fails, 5 nodes remain. Quorum is 5 / 2 + 1 = 3.5, rounded up to 4. Still has quorum. If 2 nodes fail, 4 nodes remain. Quorum is 4 / 2 + 1 = 3. Still has quorum. If 3 nodes fail, 3 nodes remain. Quorum is 3 / 2 + 1 = 2.5, rounded up to 3. Still has quorum. If 4 nodes fail, 2 nodes remain. Quorum is 2 / 2 + 1 = 2. Loses quorum. Therefore, the cluster can tolerate 3 node failures while maintaining quorum.
