D) Graph nodes
Correct Answer: B) Time-series data
Rationale: Prometheus is built around a time-series data model where
metrics are stored as streams of timestamped values identified by
metric name and key-value labels. This allows efficient tracking of
system behavior over time.
Question 2
,What is a Prometheus “target”?
A) A dashboard panel
B) A time-series database
C) An endpoint that exposes metrics
D) A query language

exposes metrics in a format Prometheus can scrape, typically over
HTTP.
Question 3
Which protocol does Prometheus primarily use to collect metrics?
A) SNMP
B) SSH
C) HTTP pull model

A) A visualization tool
B) A service that sends logs
C) A component that exposes metrics
D) A database backup tool
Correct Answer: C) A component that exposes metrics
