Explanation
Cluster quorum in ONTAP is defined as a state where a simple majority (more than half) of the participating nodes are healthy and communicating.
Common mistakes.
- A. Two-thirds is not the threshold used by ONTAP for quorum - the requirement is a simple majority, which is a lower threshold.
- C. Three-quarters is not the defined quorum threshold in ONTAP cluster architecture.
- D. Exactly half is insufficient for quorum - a simple majority requires strictly more than half of nodes to be healthy.
