A sinkhole is a router designed to accept and analyze attack traffic. Sinkholes can be used to do the following: Draw traffic away from a target Monitor worm traffic Monitor other malicious traffic

Agree. Sinkhole is the best option here. UTM's can also block this traffic, but they can be overwhelmed by the sheer volume.

Selected Answer: D
A sinkhole is a solution to prevent future DNS DDoS attacks by rerouting malicious traffic away from the target network to a separate, isolated network or device. This reduces the amount of traffic that reaches the target network, thus reducing the potential impact of the attack. This is a preferred solution as it does not rely on the Internet Service Provider (ISP) to block the attack, but rather it is managed internally by the organization, providing greater control and visibility over the mitigation process.
