When changing VLAN configurations for hosts and Controller Virtual Machines (CVMs) in a Nutanix cluster, doing so while the cluster is running can result in temporary communication losses, leading to alerts such as a node appearing down. To avoid these disruptions and ensure a smooth reconfiguration process, it is advisable to stop the cluster services before making VLAN changes. This prevents the cluster from detecting intermittent connectivity as node failures, thereby avoiding false alerts in Prism Element.

When a NearSync Replication window is missed due to high write volume during nightly backups, the expected behavior of the system is to adjust the replication schedule temporarily and continuously attempt to return to the configured NearSync schedule. The correct answers are:

Option B, "Protection Domain transitions back to the hourly schedule." If the NearSync cannot maintain the 15-minute schedule due to excessive write volume, it may temporarily fall back to a less frequent schedule, such as hourly, to stabilize.

Option D, "The system continuously tries to get to the NearSync schedule." NearSync is designed to handle transient high-load situations by trying to catch up and revert to the pre-set NearSync schedule as conditions allow.

References:These behaviors are outlined in the Nutanix documentation for NearSync, which describes how the system manages periods of high I/O and missed replication windows.
