Checkpoint 156-215.81 Online Access

This answer is correct because for a certificate-based VPN tunnel, both gateways need to have a certificate issued by a certificate authority (CA) that they trust1. A CA is a trusted entity that verifies the identity of the gateways and signs their certificates2. The gateways can either use the same CA or different CAs, as long as they trust each other’s CA3. This way, the gateways can authenticate each other using their certificates and establish a secure VPN tunnel.

The other answers are not correct because they are either irrelevant or incompatible with certificate-based VPN tunnel. Shared secret passwords and unique passwords are used for pre-shared key (PSK) authentication, which is a different method than certificate authentication4. PSK authentication is less secure and more vulnerable to brute force attacks than certificate authentication. Shared user certificates are not used for gateway authentication, but for user authentication, which is a different level of authentication than gateway authentication. User authentication is optional and can be used in addition to gateway authentication to provide more granular access control.

The correct answer is D because the command save configuration  stores the Gaia configuration in a file for later reference1. The other commands are not valid in Gaia Clish1. References: Gaia R81.10 Administration Guide

The Shared policies feature allows administrators to share a policy with other policy packages3. This can save time and effort when managing multiple gateways with similar security requirements. Shared policies can be applied to Access Control, Threat Prevention, and HTTPS Inspection layers4.

The correct answer is D because sending API commands over an http connection using web-services is not one of the ways to communicate using the Management API’s3. The Management API’s support HTTPS protocol only, not HTTP3. The other methods are valid ways to communicate using the Management API’s3.
