Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Patch compliance percentage
KPIs measure the effectiveness of security controls and processes. Mean time to respond (MTTR) measures incident response effectiveness. Patch compliance percentage measures the effectiveness of patch management. Number of vulnerabilities is a KRI, not a KPI per se. Budget spent is a financial metric. Employee satisfaction is HR-related.
