Which statement is most correct regarding about "CoreXL Dynamic Dispatcher"?
Correct Answer: B
Explanation The statement that is most correct regarding about "CoreXL Dynamic Dispatcher" is: The CoreXL FW instances assignment mechanism is based on the utilization of CPU cores. CoreXL Dynamic Dispatcher is a feature that allows the Security Gateway to dynamically assign connections to the most available CoreXL FW instance, based on the CPU core utilization. This improves the performance and load balancing of the Security Gateway, especially when handling connections with different processing requirements. The other statements are either incorrect or describe the CoreXL Static Dispatcher mechanism, which assigns connections based on a hash function of the Source IP, Destination IP, and IP Protocol type.
Question 227
From SecureXL perspective, what are the tree paths of traffic flow:
Correct 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.

Question 228
Which packet info is ignored with Session Rate Acceleration?
Correct Answer: C
Explanation Session Rate Acceleration is a SecureXL feature that accelerates the establishment of new connections by bypassing the inspection of the first packet of each session. Session Rate Acceleration ignores the source port information of the packet, as well as the destination port ranges, protocol type, and VPN information. The other packet info is used by Packet Acceleration, which is another SecureXL feature that accelerates the forwarding of subsequent packets of an established connection.

Question 229
Using mgmt_cli, what is the correct syntax to import a host object called Server_1 from the CLI?
Correct Answer: B
Explanation The correct syntax to import a host object using mgmt_cli is mgmt_cli add host name <name> ip-address <ip-address> --format <format>1. The name and ip-address parameters are mandatory, while the format parameter is optional and can be either json or txt. The other options are incorrect because they either use wrong parameters, wrong hyphens, or wrong object types. References: 1: Check Point Resource Library2
