Answers

Firewall Path; Accept Path; Drop Path
D.
Firewall Path; Accelerated Path; Medium Path
Answers
D.
Firewall Path; Accelerated Path; Medium Path
Suggested answer: D

Explanation:

SecureXL is a technology that improves the performance of Security Gateway by offloading the processing of some packets from the Firewall kernel to the SecureXL device driver1.SecureXL can handle packets in three different paths, depending on the type and state of the packet2:

Firewall Path: This is the slowest path, where packets are processed by the Firewall kernel and all the inspection blades. This path is used for packets that require full inspection, such as the first packet of a connection, packets that match a rule with a UTM blade, or packets that are not eligible for acceleration.

Accelerated Path: This is the fastest path, where packets are processed by the SecureXL device driver and bypass the Firewall kernel. This path is used for packets that belong to an established connection that is marked for acceleration, and do not require any further inspection by the Firewall or other blades.

Medium Path: This is a hybrid path, where packets are processed by both the SecureXL device driver and the Firewall kernel, but skip some inspection steps. This path is used for packets that belong to an established connection that is not marked for acceleration, but do not require full inspection by all the blades.

The other options are not correct because:

A) Initial Path; Medium Path; Accelerated Path: There is no such thing as Initial Path in SecureXL terminology. The initial packet of a connection is always handled by the Firewall Path.

B) Layer Path; Blade Path; Rule Path: These are not paths of traffic flow, but components of the unified policy in R80 and above versions.The Layer Path refers to the order of layers in the policy, the Blade Path refers to the order of blades within a layer, and the Rule Path refers to the order of rules within a blade3.

C) Firewall Path; Accept Path; Drop Path: These are not paths of traffic flow, but possible actions that the Firewall can take on a packet. The Firewall Path is one of the paths of traffic flow, but the Accept Path and Drop Path are not.The Accept Path means that the packet is allowed to pass through the Firewall, and the Drop Path means that the packet is blocked by the Firewall4.
