SmartView Monitor is a GUI client that is supported in R81. It allows you to monitor the network and security performance of your Security Gateways and devices5. You can use it to view real-time statistics, alerts, logs, reports, and graphs6. The other GUI clients are not supported in R81 because:
A) SmartProvisioning was replaced by SmartLSM in R80.20 and later versions7. SmartLSM is a unified solution for managing large-scale deployments of Security Gateways8.
B) SmartView Tracker was replaced by SmartLog in R80 and later versions9. SmartLog is a powerful log analysis tool that enables fast and easy access to log data from multiple Security Gateways10.
D) SmartLog is not a GUI client, but a web-based application that runs on the Security Management Server or Log Server10. You can access it from any web browser or from SmartConsole.

Explanation
The lock symbol in the left column of the rule means that another user has locked the rule for editing. This is to prevent multiple users from editing the same rule at the same time and causing conflicts. References:

Harmony Endpoint is a solution that provides comprehensive protection for endpoint devices against cyber threats. Harmony Endpoint includes a personal firewall that controls the network traffic to and from the endpoint device, based on predefined rules and policies. Harmony Endpoint also integrates with Check Point's VPN solutions to provide secure remote access to corporate resources1. Therefore, the customer will need Harmony Endpoint because of the personal firewall requirement.

Explanation
ClusterXL is a clustering technology that provides high availability and load sharing for Security Gateways.
ClusterXL uses a proprietary protocol called Check Point Cluster Protocol (CCP) to communicate between cluster members. CCP has two main functions: Health Check and State Synchronization. Health Check is the mechanism that monitors the status and availability of each cluster member and determines which member is the active one. State Synchronization is the mechanism that synchronizes the connection and NAT tables between cluster members to ensure a smooth failover in case of a member failure. CCP uses UDP port 8116 for both Health Check and State Synchronization messages. The other options are not correct because:
A: CCP and 18190: This option is incorrect because CCP does not use port 18190. Port 18190 is used by Secure Internal Communication (SIC) between Security Gateways and Management Servers.
B: CCP and 257: This option is incorrect because CCP does not use port 257. Port 257 is used by Check Point Security Management Protocol (CPM) for communication between SmartConsole and Management Servers.
D: CPC and 8116: This option is incorrect because there is no such protocol as CPC in ClusterXL.

After clicking "Next", the above configuration is supported by Active Directory integration which allows the Security Gateway to correlate Active Directory users and machines to IP addresses in a method that is completely transparent to the user. This is a feature of Identity Awareness that allows the Security Gateway to identify users and machines on the network and enforce security policies based on their identity. The administrator can configure Identity Awareness to use various methods for acquiring identity, including Active Directory integration, browser-based authentication, terminal servers, and transparent authentication1.
