A network engineer must connect two sites across a public network using a secure tunneling technology that supports multicast traffic. Which technology should be selected?
D is correct: "GRE tunnels allow to tunnel unicast, multicast, and broadcast traffic between routers and are often used for routing protocols between different sites. The downside of GRE tunneling is that it is clear text and offers no protection. On Cisco IOS routers however we can use IPSEC to encrypt the entire GRE tunnel, this allows us to have a safe and secure site-to-site tunnel."
