Which term is a documented record of normal network performance metrics used as a reference point for identifying anomalies?

• A. Baseline
• B. IP Address Management
• C. Change Management
• D. Configuration Backup

Answer: (A)

In network performance management, a baseline is a documented record of normal performance metrics across the network. It includes measurements such as latency, throughput, packet loss, jitter, and device utilization gathered during typical operation. This baseline serves as a reference point; when current measurements exceed or fall short of the baseline by predefined thresholds, it signals potential anomalies that warrant investigation. Baselines are best built from stable periods and updated as the network evolves (new devices, capacity changes), and they can be defined for individual devices, interfaces, or services to keep monitoring precise. The other terms aren’t about recording normal performance levels: IP Address Management deals with tracking address allocations; Change Management governs how changes to the network are proposed and approved; Configuration Backup stores device configurations for recovery.
