Question 1

In the context of observability, what are the three primary signal types (often called the 'three pillars') that systems emit to describe their internal state?

Metrics, logs, and traces Alerts, dashboards, and reports Counters, gauges, and histograms Scrapes, queries, and rules

Correct Answer:

Metrics, logs, and traces

Question 2

Which statement best describes why Prometheus uses a pull-based model for collecting metrics rather than a push-based model?

Pull requires no network configuration on the targets Pull guarantees metrics are never lost during a network partition The Prometheus server scrapes targets over HTTP, which centralizes control over scrape timing, makes target health visible via the up metric, and simplifies running multiple Prometheis Pull lets applications send metrics only when a value changes, reducing bandwidth

Correct Answer:

The Prometheus server scrapes targets over HTTP, which centralizes control over scrape timing, makes target health visible via the up metric, and simplifies running multiple Prometheis

Question 3

A team defines a target of '99.9% of HTTP requests succeed over a rolling 30-day window'. In SRE terminology, what is this statement an example of?

A Service Level Indicator (SLI) An error budget policy A Service Level Agreement (SLA) A Service Level Objective (SLO)

Correct Answer:

A Service Level Objective (SLO)

Question 4

What is the relationship between an SLO and an error budget?

The error budget is always 100% minus the SLA penalty The error budget is the portion of failures allowed by the SLO over the measurement window The error budget equals the SLO target percentage The error budget is the number of alerts a service may fire per day

Correct Answer:

The error budget is the portion of failures allowed by the SLO over the measurement window

Question 5

In distributed tracing, what is the relationship between a trace and a span?

A span contains many traces, one per service A trace represents one request's journey and is composed of one or more spans, each representing a unit of work A trace and a span are interchangeable names for the same object A span is a numeric metric while a trace is a log line
