Helping Hand Questions for 156-215.81

To achieve the requirement of giving the Network Operations Center administrator access to Check Point Security devices mostly for troubleshooting purposes, but not to the expert mode, and still allowing her to run tcpdump, you need to:

• Add tcpdump to CLISH using add command. This command adds a new command to the Command Line Interface Shell (CLISH) that allows running tcpdump without entering the expert mode .
• Create a new access role. This option defines a set of permissions and commands that can be assigned to a user or a group of users.
• Add tcpdump to the role. This option grants the permission to run tcpdump to the role.
• Create new user with any UID and assign role to the user. This option creates a new user account with any User ID (UID) and assigns the role that has tcpdump permission to the user.

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.

 A clean-up rule is a rule that is placed at the end of the security policy to drop any traffic that is not explicitly allowed by the previous rules. It is a best practice to have a clean-up rule to prevent unauthorized access and log the dropped packets for analysis12. The other options are not the purpose of a clean-up rule. References: Clean-up Rule, Check Point CCSA - R81: Practice Test & Explanation

The correct answer is D because from SecureXL perspective, the three paths of traffic flow are Firewall Path, Accelerated Path, and Medium Path3. The Firewall Path is used when SecureXL is disabled or traffic is not eligible for acceleration3. The Accelerated Path is used when SecureXL handles the entire connection and bypasses the Firewall kernel3. The Medium Path is used when SecureXL handles part of the connection and forwards packets to the Firewall kernel for further inspection3. The other options are not valid paths of traffic flow from SecureXL perspective3.
