https://kb.vmware.com/s/article/1024051The correct answers for this question are A. Microsoft SQL Server 2012/2014 AlwaysOn Availability Groups (AG) and E. Microsoft Windows Server Failover Clustering.
Explanation: vCenter Server is a critical component of the VMware vSphere virtualization platform, and any downtime of vCenter Server can impact the availability of virtual machines and other vSphere components. Therefore, it is essential to ensure the availability of the vCenter Server database. Here are the two options that can be used for vCenter Server 6.x database availability:
A. Microsoft SQL Server 2012/2014 AlwaysOn Availability Groups (AG): AlwaysOn Availability Groups is a high-availability and disaster-recovery solution provided by Microsoft SQL Server. It provides database-level failover of multiple databases, supports up to eight secondary replicas, and allows automatic or manual failover of the primary replica to a secondary replica. vCenter Server can use AlwaysOn Availability Groups to ensure high availability of its database.
E. Microsoft Windows Server Failover Clustering: Windows Server Failover Clustering is a high-availability solution provided by Microsoft Windows Server. It allows multiple servers to work together to provide high availability of services and applications. vCenter Server can use Windows Server Failover Clustering to ensure high availability of its database.
B. vCenter Server Watchdog: vCenter Server Watchdog is a built-in component of vCenter Server that monitors the health of vCenter Server services and automatically restarts them if they fail. However, Watchdog does not provide high availability of the vCenter Server database.
C. NSX load balancer: NSX load balancer is a component of VMware NSX that provides load balancing of network traffic. However, it does not provide high availability of the vCenter Server database.
D. vCenter Server Heartbeat: vCenter Server Heartbeat is a deprecated product that was previously used to provide high availability of vCenter Server. It is no longer supported and has been replaced by other solutions like AlwaysOn Availability Groups and Windows Server Failover Clustering.
