Network Performance and Capacity Planning Questions

Covers monitoring, testing, design, and capacity forecasting for network infrastructure. Candidates should know key network performance metrics such as bandwidth utilization, latency, jitter, packet loss, throughput, and error rates; how to establish a performance baseline and detect anomalies; common network monitoring techniques and tools for traffic analysis and device statistics; methods for network performance testing and validation including active throughput and latency tests; and basic capacity planning and upgrade strategies for small sites and departmental networks. Also includes considerations for quality of service, redundancy, modest growth forecasting, and tradeoffs when designing small scale network segments and link capacities.
