What is required to maintain High Availability in the case of a node failure?
To maintain High Availability in a two-node cluster at a ROBO (Remote Office/Branch Office) site in the event of a node failure, a Witness VM is required. The Witness VM helps to prevent split-brain scenarios by acting as a tiebreaker, ensuring that the cluster remains operational and that data integrity is maintained. This setup is necessary because, with only two nodes, there is a risk that the cluster might not be able to resolve which node should continue operating alone if communication is lost between the two nodes.
dont think C is correct - documentation says a witness VM
Answer: Witness VM The witness VM must reside in a separate failure domain, which means that you need independent power and network connections from each of the two-node clusters. We recommend locating the witness VM in a third physical site with dedicated network connections to site one and site two to avoid a single point of failure.
