Which technique helps network administrators develop new filtering techniques and update load balancing and throttling countermeasures?

• A. Traffic Pattern Analysis
• B. Event Log Analysis
• C. Cisco IPS Source IP Reputation Filtering
• D. RFC 3704 Filtering

Answer: (A)

Analyzing traffic patterns lets you see how data normally flows and how it changes under different conditions. By collecting flow data, throughput, timing, packet sizes, and session counts, you establish baselines and can spot deviations quickly. When new or unusual patterns appear—sudden spikes, unfamiliar ports, new destinations, or shifts in traffic mix—you can craft targeted filtering rules and adjust how load balancers distribute or throttle traffic. This approach directly supports developing new filters and updating throttling and balancing countermeasures to handle evolving traffic and threats. Event logs are great for investigations and auditing, but they don’t provide the real-time, pattern-based visibility needed to design new traffic filters or rate-limiting strategies. IPS reputation filtering relies on known bad IPs rather than discovering and adapting to new traffic behaviors. RFC 3704 filtering focuses on preventing IP spoofing, not on evolving filtering techniques or load-balancing responses.
