Explanation
DDoS Attack Prevention's two core features are automatic traffic control (A) and rapid mitigation speed (D). These systems are designed to intelligently distinguish malicious flood traffic from legitimate requests and block it automatically - no manual intervention required - and to act fast enough (within seconds of detection) to prevent meaningful service disruption.
Why the distractors are wrong:
- B is incorrect because redirecting attack traffic back to the attacker is not a standard DDoS mitigation technique; it would constitute a counterattack, which is both legally problematic and not how these systems work.
- C is incorrect because AMP ThreatGrid is Cisco's malware analysis sandbox technology, not a DDoS mitigation feature - this is a classic distractor that mixes two different security product categories.
Memory tip: Think of DDoS prevention with two words - "Auto" and "Fast". It automatically blocks bad traffic (A) and acts fast (seconds, not minutes) (D). If an answer sounds like hacking back or involves malware sandboxing, it's the wrong domain.
