CCDE: Cisco Certified Design Expert (Written) — Question 38

Company X will be integrating an IPv6 application into their network and wants to develop a test environment to evaluate application performance across the network. This application will require both unicast and multicast communications. The company can do this implementation only in certain areas of its existing
IPv4-only network, but wants all areas to communicate with each other. When developing the design to provide connectivity between these testing locations, what tunneling technology would work in this scenario?

Answer options

• A. ISATAP
• B. 6to4
• C. DMVPN
• D. 6vPE
• E. 6PE

Correct answer: C

Explanation

DMVPN (Dynamic Multipoint Virtual Private Network) is the correct choice as it allows for dynamic and scalable communication between multiple sites over an IPv4 infrastructure while supporting IPv6 applications. The other options, such as ISATAP and 6to4, are less suited for establishing dynamic multi-site connectivity, and 6vPE and 6PE are more focused on service provider scenarios rather than direct site-to-site connections.
