In a node majority cluster with an odd number of nodes, the cluster does not require a ____.

• A. Quorum
• B. Witness
• C. Cluster Master
• D. Disk

Answer: (B)

Quorum decisions in a node-majority cluster are based on votes, with each node contributing one vote and the cluster staying online only while more than half the votes are available. When you have an odd number of nodes, the total votes are odd, so there cannot be a tie. That means the nodes alone provide a clear majority to maintain quorum, and an external witness is not needed. For example, with three nodes, a majority is two votes. If any two nodes are online, quorum is achieved without a witness. If only one node is online, quorum isn’t met, and the cluster won’t stay online. A disk or file share witness is typically used to add an extra vote to break ties or to help sustain quorum in even-numbered configurations, but it isn’t required in an odd-numbered node-majority setup.
