In R81, you can manage your Mobile Access Policy through the Unified Policy. The Unified Policy is a single policy that combines access control, threat prevention, data protection, and identity awareness. You can create rules for mobile access in the Unified Policy rulebase and apply them to mobile devices, users, and applications. You can also use the Mobile Access blade to configure additional settings for mobile access, such as authentication methods, VPN settings, and application portal.

The Management API supports three methods of communication: mgmt_cli command, SmartConsole GUI dialog box, and Gaia CLI. Sending API commands over an http connection using web-services is not a supported method. Reference: Check Point Management APIs

Implied rules are predefined rules that are automatically added to the Access Control rulebase by the Security Management Server. Implied rules allow the control connections that are essential for the functionality and security of the Check Point products, such as communication between the Security Gateway and the Security Management Server, synchronization between cluster members, logging, VPN, and ICMP. Implied rules are not visible in the SmartConsole, but they can be viewed and modified using the Global Properties window.

CoreXL is a performance-enhancing technology that enables the processing CPU cores to concurrently perform multiple tasks on Security Gateways with multiple CPU cores. CoreXL replicates the Firewall kernel multiple times, creating multiple Firewall instances that run on different CPU cores. These Firewall instances handle traffic concurrently, and each Firewall instance is a complete and independent Firewall inspection kernel. To show the current connections distributed by CoreXL FW instances, you can use the command fw ctl multik stat on the Security Gateway. This command will display information such as the number of connections, packets, bytes, drops, and errors handled by each CoreXL FW instance, as well as the CPU utilization and affinity of each instance. The other options are not correct because:
B) fw ctl affinity -l: This command will show the CPU affinity of all processes and IRQs on the Security Gateway. It will not show the current connections distributed by CoreXL FW instances.
C) fw ctl instances -v: This command will show the details of all CoreXL FW instances on the Security Gateway, such as their ID, type, state, priority, and interfaces. It will not show the current connections distributed by CoreXL FW instances.
D) fw ctl iflist: This command will show the list of all interfaces on the Security Gateway, along with their names

The command that lists all interfaces using Multi-Queue is cpmq get. Multi-Queue is a feature that allows network interfaces to use multiple transmit and receive queues, which improves the performance and scalability of the Security Gateway by distributing the network load among several CPU cores. Cpmq is a command that allows administrators to configure and manage Multi-Queue settings on network interfaces. Cpmq get lists all interfaces using Multi-Queue and shows their queue count and core distribution.
