Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 606

Which feature minimizes DoS attacks on an IPv6 network?

Answer options

• A. IPv6 Binding Security Table
• B. IPv6 Router Advertisement Guard
• C. IPv6 Prefix Guard
• D. IPv6 Destination Guard

Correct answer: D

Explanation

The correct answer, IPv6 Destination Guard, prevents unwanted traffic directed to the host by ensuring that only valid destination addresses are allowed. The other options, while they provide security features, do not specifically address the mitigation of DoS attacks as effectively as Destination Guard does.
