With SecureXL enabled, accelerated packets will pass through the following:  Network Interface Card and the Acceleration Device . SecureXL is a technology that accelerates network traffic processing by offloading intensive operations from the Firewall kernel to a dedicated SecureXL device. Accelerated packets are packets that match certain criteria and can be handled by SecureXL without involving the Firewall kernel. These packets bypass the OSI Network Layer, OS IP Stack, and Check Point Firewall Kernel, and are processed directly by the Network Interface Card and the Acceleration Device.  The other options are either incorrect or describe non-accelerated packets.

The port that the CPM process runs on is  TCP 19009 . CPM stands for Check Point Management, and it is the main process that runs on the Security Management Server and interacts with SmartConsole clients. CPM is responsible for managing policies, objects, logs, tasks, and other management functions. CPM listens on TCP port 19009 for incoming connections from SmartConsole clients.  The other ports are either used by other processes or not related to CPM. 

Session unique identifiers are passed to the web API using the  X-chkp-sid  HTTP header option. The web API is a service that runs on the Security Management Server and enables external applications to communicate with the Check Point management database using REST APIs. To use the web API, you need to create a session with the management server by sending a login request with your credentials. The management server will respond with a session unique identifier (SID) that represents your session. You need to pass this SID in every subsequent request to the web API using the X-chkp-sid HTTP header option. This way, the management server can identify and authenticate your session and perform the requested operations. References:  Check Point R81 REST API Reference Guide

 The most ideal Synchronization Status for Security Management Server High Availability deployment is  Synchronized . Security Management Server High Availability deployment is a feature that allows two or more Security Management Servers to provide redundancy and load balancing for managing security policies and logs. Synchronization Status is a parameter that indicates how up-to-date the databases of the Security Management Servers are with each other. Synchronization Status can have one of the following values: Synchronized, Lagging, Never been synchronized, or Collision. Synchronized means that the databases of all Security Management Servers are identical and have no conflicts. This is the most ideal status as it ensures consistency and reliability of security management. Lagging means that one or more Security Management Servers have not received all the updates from other Security Management Servers, and their databases are outdated. Never been synchronized means that one or more Security Management Servers have never synchronized their databases with other Security Management Servers, and their databases are independent.  Collision means that one or more Security Management Servers have received conflicting updates from other Security Management Servers, and their databases have discrepancies.

 How many interfaces can you configure to use the Multi-Queue feature? You can configure up to  5 interfaces  to use the Multi-Queue feature. Multi-Queue is a performance enhancement feature that allows distributing the network traffic among multiple CPU cores, instead of using a single core for all traffic. Multi-Queue can be enabled on interfaces that have high traffic load and support multiple receive/transmit queues. Multi-Queue can be configured via SmartConsole or via CLI with the command  sim affinity -m . References:  R81 Performance Tuning Administration Guide , page 18.
