Check Point Certified Security Expert (CCSE) R81 — Question 20

What are valid authentication methods for mutual authenticating the VPN gateways?

Answer options

• A. PKI Certificates and Kerberos Tickets
• B. PKI Certificates and DynamicID OTP
• C. Pre-Shared Secrets and Kerberos Ticket
• D. Pre-shared Secret and PKI Certificates

Correct answer: D

Explanation

The correct answer is D because both Pre-shared Secrets and PKI Certificates are widely used methods for mutual authentication in VPNs. Options A and B include Kerberos, which is not typically utilized for VPN gateway mutual authentication, while option C combines Pre-Shared Secrets with Kerberos, which also doesn't align with standard practices.
