Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 308

What are two features of 6RD IPv6 transition mechanism? (Choose two.)

Answer options

• A. It inserts IPv4 bits into an IPv6 delegated prefix.
• B. It uses a native IPv6-routed network between CE routers and the BR router.
• C. It allows dynamic 1:N translation of IPv6 address.
• D. It uses stateful automatic 6to4 tunnels between CE routers and the BR router.
• E. It uses stateless automatic 6to4 tunnels between CE routers and the BR router.

Correct answer: A, E

Explanation

Option A is correct because 6RD involves embedding IPv4 bits into an IPv6 prefix to facilitate transition. Option E is also correct as 6RD employs stateless automatic 6to4 tunnels for communication. The other options are incorrect because they either describe mechanisms not specific to 6RD or refer to features that do not align with its operation.
