Which of the following are the prevention mechanisms supported by Huawei Anti-DDoS? (Multiple choice)

Question

Options

• ASession check
• BCurrent limiting
• CFilter
• DFirst package inspection

• A
  100% (30)

Explanation

Huawei Anti-DDoS employs all four listed mechanisms as part of its multi-layered defense strategy. Session check (A) validates the legitimacy of TCP/UDP sessions, filtering out spoofed or incomplete handshakes common in SYN flood attacks. Current limiting (B) enforces rate thresholds on incoming traffic to prevent bandwidth and resource exhaustion. Filter (C) applies signature- and rule-based packet inspection to block traffic matching known attack patterns. First package inspection (D) analyzes the initial packet of a new flow to decide whether to allow the session before any resources are committed - an efficient early-drop mechanism.

Since all four options are correct, there are no distractors in this question - it is testing comprehensive recall of the full feature set, not the ability to eliminate wrong choices.

Memory tip: Use the acronym "SC-FL-FI-FP" → Session Check, Flow Limiting, Filter, First Package - or think of it as a security funnel: you check the session, limit the rate, filter by rules, and inspect the first packet. All four layers together = Huawei Anti-DDoS.
