Implementing Cisco Service Provider Advanced Routing Solutions (SPRI) — Question 29

What are three requirements for a static IPv6-in-IPv4 tunnel? (Choose three.)

Answer options

• A. A dynamic IPv6 address must be configured
• B. A dynamic IPv4 address must be configured
• C. A static IPv4 address must be configured
• D. A static IPv6 address must be configured
• E. Each tunnel endpoint must support IPv4 and IPv6
• F. Cisco Express Forwarding must be enabled

Correct answer: C, D, E

Explanation

The correct answers, C, D, and E, are essential because a static IPv4 address and a static IPv6 address are required to set up the tunnel, and both ends must support IPv4 and IPv6 protocols. Options A and B are incorrect since dynamic addresses are not a requirement for static tunnels, and F is not needed for the basic functioning of the tunnel.
