The correct command to store the GAIA configuration in a file is save configuration 1. This will create a file with the current system level configuration in the home directory of the current user1. The other commands are incorrect because they either do not exist or do not save the configuration to a file.

 SecureXL templates are a mechanism to accelerate the rate of connection establishment by grouping connections that match a particular service and whose sole differentiating element is the source port. SecureXL templates enable even the very first packets of a TCP handshake to be accelerated, without waiting for the Firewall kernel to create a connection entry. The first packets of the first connection on the same service will be forwarded to the Firewall kernel, which will then create a template of the connection. The template will contain all the relevant information for the connection, such as source and destination IP addresses, destination port, NAT information, policy decision, etc. The template will be used by SecureXL to handle subsequent connections on the same service, without involving the Firewall kernel. This reduces the CPU load and increases the throughput.

There are three types of SecureXL templates: Accept, Drop, and NAT. Accept templates are used for connections that are allowed by the Firewall policy. Drop templates are used for connections that are blocked by the Firewall policy. NAT templates are used for connections that require NAT translation. Deny templates are not a valid type of SecureXL template.

The Sticky Decision Function in ClusterXL is primarily used in Load Sharing implementations. In Load Sharing, the pivot member is responsible for determining the destination of new connections and ensures that traffic from the same source IP address is directed to the same cluster member. This ensures session stickiness for the same source IP, improving load sharing efficiency.

 The main stages of a policy installation are Verification & Compilation, Transfer and Commit. Verification & Compilation is the stage where the Security Management Server checks the validity and consistency of the policy and compiles it into a binary format. Transfer is the stage where the compiled policy is sent to the Security Gateways over a secure channel. Commit is the stage where the Security Gateways activate the new policy and update their connections table accordingly. References: Check Point Security Expert R81 Course, Policy Installation Process
