What type of cluster can a Security Group can be compared to?

A Security Group in a Check Point Scalable Platform (Maestro) environment is a logical collection of Security Gateway Modules (SGMs) that work together as a single entity. All SGMs within the group are active and process traffic simultaneously. An Orchestrator distributes the traffic load across all active SGMs. This operational model is functionally equivalent to a traditional ClusterXL cluster configured in Load Sharing Active/Active mode, where all members are active and share the traffic load.

B. VSLS (Virtual System Load Sharing) is a specific mode for VSX environments, while a Security Group is a more general concept applicable to non-VSX gateways as well.
C. Active / Backup is a synonym for Active/Standby and is incorrect because all members of a Security Group are active, not just one.
D. Active / Standby involves one active member processing all traffic while others wait in a passive state, which is contrary to how a Security Group operates.

The guide explicitly states: "A Security Group is a logical group of Security Gateway Modules (SGMs). It is equivalent to a traditional Check Point ClusterXL in Load Sharing mode."

2. Check Point. (2023). R81.20 ClusterXL Administration Guide. Chapter 3, "Load Sharing". This chapter describes the Active/Active nature of Load Sharing, which directly corresponds to the functionality of a Security Group.
