Which statement is true regarding redundancy?

The statement regarding redundancy that is true is that both ClusterXL and VRRP are fully supported by Gaia and available to all Check Point appliances, open servers, and virtualized environments. This means that these technologies are integrated within the Gaia operating system, which is the foundation for Check Point's security appliances, allowing for effective high availability and disaster recovery solutions across various hardware and virtual platform configurations.

ClusterXL is designed to provide advanced clustering capabilities, supporting load balancing and high availability, while VRRP (Virtual Router Redundancy Protocol) helps to ensure seamless failover for IP routing. Both technologies enhance a network's reliability and availability, which are critical in maintaining continuous service in security environments. Being fully supported in Gaia ensures that administrators can leverage these clustering technologies in their network design without compatibility issues.

In the context of the other options, one points out a command related to cluster failover, but it does not capture the broader applicability of redundancy solutions like ClusterXL and VRRP. Another choice mentions specific load-sharing solutions provided by ClusterXL but does not address the full support aspect within Gaia. Lastly, the requirement for synchronization in High Availability configurations is specifically relevant to ClusterXL but does not encompass the complete picture offered by VRRP, which can operate under different conditions
