You have an on‑premises, two‑node, hyperconverged Windows Server Failover Cluster named Cluster1 and an Azure subscription. To configure a cloud witness for Cluster1, which type of Azure Storage must you use?

To configure a cloud witness for a Windows Server Failover Cluster, you must use Azure Blob Storage. Specifically, it leverages a blob in a general-purpose Azure Storage account to act as the witness. This blob is a small file that the cluster nodes use to maintain quorum. Azure File Storage (file) is used for file shares and is not the correct mechanism for a cloud witness. Azure Queue Storage (queue) is for storing large numbers of messages, and Azure Table Storage (table) is for structured NoSQL data, neither of which is designed for cluster quorum.
