To enable VMAC mode on a cluster member, you need to set the value of the global kernel parameter fwha_vmac_global_param_enabled to 1. This can be done on-the-fly using the command fw ctl set int fwha_vmac_global_param_enabled 1 on all cluster members. This command does not require a reboot or a policy installation. VMAC mode allows the cluster to use a virtual MAC address for its virtual IP addresses, which reduces the number of gratuitous ARP packets sent upon failover and avoids ARP cache issues on some routers and switches.

Check Point API is a set of web services that enable the usage of functions and commands in a dynamic and automated fashion. Check Point API is available in different types, each serving a different purpose and functionality. According to the Check Point Resource Library1, the following are the types of Check Point API available in R81.x:

• Identity Awareness Web Services: This type of API allows external applications to send identity and location information to the Security Gateway, which can then use this information for policy enforcement. Identity Awareness Web Services can be used for scenarios such as guest registration, captive portal, identity agents, etc.
• OPSEC SDK: This type of API provides a framework for developing applications that interact with Check Point products using the OPSEC (Open Platform for Security) protocol. OPSEC SDK can be used for scenarios such as log export, event management, anti-virus integration, etc.
• Management: This type of API allows external applications to perform management operations on the Check Point Management server using RESTful web services. Management API can be used for scenarios such as policy installation, object creation, configuration backup, etc.

Mobile Access is not a type of Check Point API, but rather a feature that provides secure remote access to corporate resources from various devices. Mobile Access uses SSL VPN technology and supports different authentication methods and access scenarios.

 The correct command to add an “emailserver1” host with IP address 10.50.23.90 using GAiA management CLI is mgmt: add host name emailserver1 ip-address 10.50.23.90. This command will create a new host object in the Security Management Server database, with the specified name and IP address. The mgmt: prefix indicates that the command is executed on the Security Management Server, and not on the local GAiA machine. The other commands are either missing the mgmt: prefix, or have incorrect syntax or parameters. 

 For best practices, the recommended time for automatic unlocking of locked admin accounts is 30 minutes at least. Admin accounts can be locked due to failed login attempts, password expiration, or manual locking by another admin. To prevent unauthorized access or brute force attacks, locked admin accounts should not be unlocked automatically too soon. The recommended minimum time for automatic unlocking is 30 minutes, which can be configured from the SmartConsole under Manage > Permissions and Administrators > Advanced > Unlock locked administrators after. 

Check Point APIs let system administrators and developers make changes to the security policy with CLI tools and web-services. You can use an API to:

• Use an automated script to perform common tasks

• Integrate Check Point products with 3rd party solutions

• Create products that use and enhance the Check Point solution

 The command that would be used to set the network interfaces’ affinity in Manual mode is sim affinity -s. Sim affinity is a command that allows administrators to view and modify the CPU core affinity of network interfaces and SecureXL instances. Core affinity is a feature that binds network interfaces and SecureXL instances to specific CPU cores, which improves the performance and load balancing of the Security Gateway. Sim affinity -s sets the network interfaces’ affinity in Manual mode, which means that administrators can manually assign network interfaces to CPU cores. The other options are either invalid or perform different functions. 

The command that would show the API server status is api status. API stands for Application Programming Interface, and it is a web service that allows external applications to interact with the Check Point management server using standard methods such as HTTP(S) requests and JSON objects. API status is a command that shows the current status of the API server, such as whether it is enabled or disabled, running or stopped, listening on which port, using which certificate, etc. The other commands are either invalid or perform different functions. 

Tom’s changes will have been stored on the Management when he reconnects and he will not lose any of his work.

This is because SmartConsole has a feature called Concurrent Administration, which allows multiple administrators to work on the same Security Policy simultaneously, without blocking each other or creating conflicts. Concurrent Administration uses a locking mechanism to prevent multiple administrators from modifying the same rule or object at the same time. When an administrator clicks on a rule or an object, it becomes locked and a lock icon appears next to it. The lock icon shows the name of the administrator who is working on that rule or object, and prevents other administrators from editing it until it is unlocked12.

Concurrent Administration also has a feature called Session Persistence, which preserves the changes made by an administrator in case of a network failure or a SmartConsole crash. When an administrator reconnects to the Management Server after a network failure or a SmartConsole crash, they can resume their work from where they left off, without losing any changes. The changes are stored locally on the administrator’s machine until they are published to the Management Server13.

Therefore, if Tom has connected to the R81 Management Server remotely using SmartConsole and is in the process of making some Rule Base changes, when he suddenly loses connectivity, his changes will not be lost. They will be stored locally on his machine and he can resume his work when he reconnects to the Management Server.
