Question
A new technician has been tasked with implementing a QoS policy for the Network. The technician decides it would be best to monitor the information traversing the network to gain statistical information on ports and protocols utilized. Which of the following tools should the technician use to complete this objective QUICKEST?
Options
- ATraffic analyzer
- BNetwork sniffer
- CSNMPv3
- DSystem logs

Explanation
A traffic analyzer (e.g., NetFlow analyzer) is purpose-built to collect and aggregate statistical data about network traffic - including ports used, protocols, bandwidth consumption, and flow information - across the entire network quickly. A network sniffer (B) captures raw packets and requires manual analysis, making it slower for statistical summarization. SNMPv3 (C) monitors device health metrics (CPU, memory, interface counters) but does not provide deep traffic/protocol statistics. System logs (D) record events but are not designed for real-time traffic profiling. For fast, high-level QoS planning based on port/protocol usage, a traffic analyzer is the correct and quickest choice.
