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.

Dynamic Dispatch is a feature that enhances CoreXL performance by dynamically assigning new connections to CoreXL FW instances based on their CPU utilization1. To enable Dynamic Dispatch on Security Gateway without enabling Firewall Priority Queues (FPQ), you need to run the command fw ctl multik set_mode 4 in Expert mode and reboot2. This command will set the CoreXL mode to Dynamic Dispatcher without FPQ. The other options are not correct because:

• A. fw ctl Dyn_Dispatch on: This command does not exist and will return an error message.
• B. fw ctl Dyn_Dispatch enable: This command does not exist and will return an error message.
• D. fw ctl multik set_mode 1: This command will set the CoreXL mode to Static Dispatcher without FPQ, which is the default mode2. This mode will use a static hash function to assign new connections to CoreXL FW instances based on their IP addresses and protocol.

 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.

Threat Extraction is a software blade that always delivers a file to user. Threat Extraction removes or sanitizes the active content from the files and converts them to PDF format, which is safer and more compatible. Threat Extraction can also work together with Threat Emulation to provide both clean and original files to the users. Threat Extraction works on MS Office, PDF, and archive files, but not on executables. Threat Extraction can take up to 3 minutes to complete, depending on the file size and complexity.
