Which term is used as a reference point to compare current performance against past measurements?

• A. Baseline
• B. Monitoring Control
• C. Change Management
• D. Metrics

Answer: (A)

Baseline is the reference point for comparing current performance to past measurements. It comes from historical data under normal operation, and you use it to spot deviations and trends. For example, if typical CPU usage is 30% and it jumps to 85%, the baseline helps you recognize this anomaly. The other terms describe different ideas: monitoring control is the ongoing act of watching systems, change management governs how changes are proposed and approved, and metrics are the actual measurements collected rather than the reference point you compare against.
