When evaluating technical requirements for Cluster2, what is the minimum number of Azure Site Recovery Providers you must install?

For Azure Site Recovery (ASR) to protect a Hyper-V cluster, you must install the Azure Site Recovery Provider on each node of the cluster. Cluster2 has four nodes, meaning each node requires an installation of the ASR Provider. Therefore, a minimum of four Azure Site Recovery Providers must be installed. Installing fewer than four would leave some cluster nodes unprotected, preventing ASR from fully managing the cluster's replication and recovery. The other options (1, 12, 16) are incorrect because they do not match the number of nodes in the cluster, which is the direct determinant of the required Provider installations.
