Which feature in Check Point ensures that a gateway can failover without a loss of continuity?

State Synchronization is the feature in Check Point that enables a gateway to achieve high availability and ensures that failover occurs without a loss of continuity. This feature allows active and standby gateways to maintain synchronized session information, which is crucial for seamless service continuity during a failover event.

When implemented, State Synchronization keeps track of the current sessions, connections, and the state information of the network traffic being processed. In the event that the active gateway fails or needs to be taken offline for maintenance, the standby gateway can take over the active role without interruption, as it has access to the most up-to-date session information.

This is particularly important for environments that require continuous availability and minimal downtime, as it ensures that users do not experience dropped connections or lost data during the transition from one gateway to another. Other features, while beneficial for security and traffic management, do not specifically address the need for maintaining session continuity during a failover scenario.
