Question

You have a cluster of eight nodes with node majority quorum. Four nodes are in SiteX, and four are in SiteY. SiteX and SiteY can no longer communicate due to WAN failure. SiteY continues to provide clustered services, but SiteX goes offline. What feature in Windows Server 2016 caused SiteY to continue to provide services while SiteX did not?

Answer 1

In Windows Server 2016, the feature that allows SiteY to continue providing services while SiteX goes offline is Failover Clustering.

Step-by-step explanation:

Windows Server 2016 and Failover Clustering

In Windows Server 2016, the feature that allows SiteY to continue providing services while SiteX goes offline is Failover Clustering.

Failover Clustering is a feature of Windows Server that allows multiple servers to work together to provide high availability and fault tolerance for clustered services. In this scenario, the eight nodes are configured in a cluster with node majority quorum.

With node majority quorum, a majority of the nodes in the cluster must be online and able to communicate with each other for the clustered services to remain available. In this case, with four nodes in SiteX and four nodes in SiteY, SiteY can still communicate with a majority of the nodes and continue providing services while SiteX is offline due to the WAN failure.
