Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 291

The network administrator must implement IPv6 in the network to allow only devices that not only have registered IP addresses but are also connecting from assigned locations. Which security feature must be implemented?

Answer options

• A. IPv6 Snooping
• B. IPv6 Destination Guard
• C. IPv6 Router Advertisement Guard
• D. IPv6 Prefix Guard

Correct answer: D

Explanation

The correct answer is D, IPv6 Prefix Guard, which prevents devices from using unauthorized prefixes and ensures that only legitimate devices can connect from assigned locations. The other options, while related to IPv6 security, do not specifically restrict connections based on registered IP addresses and their locations.
