Explanation

Network Intrusion Detection Systems (NIDS) are purpose-built tools that continuously analyze network traffic in real time, flagging suspicious patterns, anomalies, or known attack signatures - making them the standard methodology for network traffic monitoring. Manual log reviews (B) are reactive and human-dependent, prone to delay and oversight, not a systematic monitoring tool. Social media monitoring (C) tracks online content and public sentiment, with no relevance to network infrastructure. Public Wi-Fi monitoring (D) refers to observing activity on open wireless networks, which is a narrow context rather than a general monitoring methodology.

Memory tip: Think "NIDS watches the network highway 24/7 automatically" - if a question mentions automated, real-time, or traffic analysis, NIDS is your answer.
