Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 280

What is a function of NPTv6?

Answer options

• A. It interferes with encryption of the full IP payload.
• B. It maintains a per-node state.
• C. It is checksum-neutral.

Correct answer:

Explanation

The correct answer is B, as NPTv6 is designed to maintain state information for each node involved in the translation process. Option A is incorrect because NPTv6 does not interfere with encryption, and option C is misleading since while NPTv6 is designed to be transparent, its operation does not inherently guarantee checksum neutrality.
