# Section 1: Performance Metrics & Key Performance Indicators (KPIs)
(1–20)
**1.** What is the difference between a metric and a Key Performance
Indicator (KPI)?
A) Metrics are qualitative; KPIs are quantitative
B) All metrics are KPIs, but not all KPIs are metrics
C) KPIs are a subset of metrics directly tied to business objectives and
critical success factors
D) Metrics measure past performance; KPIs predict future performance
**Answer:** C
**Rationale:** KPIs are specific, measurable values that demonstrate
how effectively an organization is achieving key business objectives.
While all KPIs are metrics, not all metrics are KPIs—only those that are
strategically important.
**2.** Which of the following is a leading indicator (predictive) rather
than a lagging indicator?
A) Customer satisfaction score
B) Revenue growth
,3|Page
C) Number of active users currently in the system (concurrent users)
D) Quarterly sales
**Answer:** C
**Rationale:** Leading indicators predict future performance.
Concurrent users indicate current load and can predict system
degradation before user complaints. Lagging indicators (customer
satisfaction, revenue) measure outcomes after the fact.
**3.** An SLA (Service Level Agreement) defines:
A) The maximum budget for IT operations
B) Agreed-upon performance targets between a service provider and
customer (e.g., uptime, response time)
C) A type of load testing tool
D) A security certification
**Answer:** B
**Rationale:** SLAs are formal agreements specifying measurable
performance standards (e.g., 99.9% availability, <200ms response time)
and consequences for non-compliance. They are foundational to IT
service management.

**4.** The "golden signals" of monitoring (according to Google SRE)
include:
A) CPU, memory, disk, network
B) Latency, traffic, errors, saturation
C) Uptime, downtime, MTBF, MTTR
D) Revenue, cost, profit, ROI
**Answer:** B
**Rationale:** The four golden signals are: Latency (time to process
request), Traffic (demand on system), Errors (rate of failed requests),
Saturation (how "full" the system is). They provide a comprehensive
view of system health.
**5.** Which metric measures the average time to resolve an incident
from detection to closure?
A) MTBF (Mean Time Between Failures)
B) MTTR (Mean Time to Repair/Resolve)
C) MTTD (Mean Time to Detect)
D) SLA (Service Level Agreement)
**Answer:** B
