Correct Answer:
D
The valid SecureXL paths in R81.20 areF2F (Slow path), Accelerated Path, Medium Path and F2V1.SecureXL is a technology that accelerates the performance of the Security Gateway by offloading CPU-intensive operations to the SecureXL device2.SecureXL uses different paths to process packets, depending on the type and state of the connection3.The SecureXL paths are3:
F2F (Slow path): This path handles packets that require a full inspection by the Firewall kernel. It is the slowest path, but it supports all features and blades. Examples of packets that use this path are packets that belong to a new connection, packets that match a rule with UTM blades, or packets that require address translation.
Accelerated Path: This path handles packets that belong to an established connection that does not require any further inspection by the Firewall kernel. It is the fastest path, but it supports only a limited set of features and blades. Examples of packets that use this path are packets that match an accept rule with no UTM blades, or packets that match a rule with SecureXL acceleration enabled.
Medium Path: This path handles packets that belong to an established connection that requires some inspection by the Firewall kernel, but not a full inspection. It is faster than the F2F path, but slower than the Accelerated path. It supports more features and blades than the Accelerated path, but less than the F2F path. Examples of packets that use this path are packets that match a rule with IPS or Anti-Bot blades, or packets that require NAT templates.
F2V: This path handles packets that are encapsulated or decapsulated by the VPN kernel. It is faster than the F2F path, but slower than the Accelerated path. It supports VPN features such as encryption, decryption, encapsulation, and decapsulation.
