Troubleshooting and Maintaining Cisco IP Networks (TSHOOT, legacy) — Question 47

You must connect two remote sites over the public Internet. Multicast support, security, and simplicity are required. Which tunneling technology should you consider?

Answer options

• A. GET VPN
• B. IPsec
• C. GRE over Ipsec
• D. MPLS

Correct answer: A

Explanation

GET VPN is designed specifically for secure communication between multiple sites over the Internet, providing multicast support and simplicity. IPsec, while secure, does not inherently support multicast traffic. GRE over IPsec can add complexity and does not provide the same level of multicast efficiency as GET VPN. MPLS is more suited for service provider networks rather than direct Internet connections.
