az-801 Practice Question 1909
Exam: az-801
Domain: Implement and manage Windows Server high availability
Topic: Implement a Windows Server failover cluster
Difficulty: medium
In a Windows Server Failover Cluster environment, you need to ensure that the cluster can maintain quorum even if one node fails. Which of the following should you configure to achieve this? Assume you have three nodes in your cluster and no external storage is available.
Answer Options
A
Cloud Witness
B
Majority Node Set
C
Node Majority
D
Disk Witness
Correct Answer
A: Cloud Witness
Explanation
A Cloud Witness is used to ensure quorum in a Windows Server Failover Cluster when an external storage solution is not available. It provides a reliable way to determine which node should be the active node in case of a failure. Option B (Majority Node Set) is incorrect because it requires more than half of the nodes to be online, which is not possible with only three nodes. Option C (Node Majority) is also incorrect as it requires more than half of the nodes to be online, which again is not possible with only three nodes. Option D (Disk Witness) is incorrect because it requires an external storage solution, which is not available in this scenario.
