Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 408

Which two VPN tunneling protocols support the use of IPsec to provide data integrity, authentication, and data encryption? (Choose two.)

Answer options

Correct answer: C, D

Explanation

Generic Routing Encapsulation Protocol (GRE) and Layer 2 Tunneling Protocol (L2TP) can both work with IPsec to provide strong security features. The other options, such as Secure Socket Tunneling Protocol (SSTP) and OpenVPN, do not rely on IPsec for their security, while Point-to-Point Tunneling Protocol (PPTP) is known for its weak security standards.
