1. What is the primary purpose of Grafana in an observability stack?
A. Data storage engine
B. Data visualization and monitoring platform
C. Log ingestion agent
D. Network firewall
Answer: B
Rationale: Grafana is primarily used to visualize metrics, logs, and
traces from multiple data sources, enabling monitoring and
observability rather than storing or ingesting data directly.
2. Which of the following is NOT a supported Grafana data source?
A. Prometheus
B. Loki
, C. MySQL
D. Kubernetes kernel module
Answer: D
Rationale: Grafana supports databases and observability systems like
Prometheus, Loki, and MySQL, but Kubernetes kernel modules are not
data sources.
3. What is a Grafana dashboard primarily used for?
A. Writing backend code
B. Storing logs
C. Visualizing metrics and data
D. Managing operating systems
Answer: C
Rationale: Dashboards in Grafana are designed to visualize time-
series data and other observability information in graphical form.
4. Which component is used for log aggregation in Grafana’s
ecosystem?
A. Prometheus
B. Loki
, C. Tempo
D. Cortex
Answer: B
Rationale: Loki is Grafana’s log aggregation system designed to work
efficiently with labels similar to Prometheus.
5. What is Grafana Loki optimized for?
A. Metrics storage
B. Distributed tracing
C. Log aggregation with low cost indexing
D. Database replication
Answer: C
Rationale: Loki is optimized for cost-effective log aggregation by
indexing metadata rather than full log content.
6. Which tool is used for distributed tracing in Grafana?
A. Tempo
B. Loki
C. Prometheus
D. Elasticsearch
, Answer: A
Rationale: Grafana Tempo is designed for distributed tracing and
helps visualize request flows across services.
7. What is Prometheus primarily used for in Grafana setups?
A. Log storage
B. Metrics collection and monitoring
C. CI/CD automation
D. User authentication
Answer: B
Rationale: Prometheus collects and stores time-series metrics used for
monitoring systems and services.
8. What language is commonly used in Prometheus queries?
A. SQL
B. PromQL
C. LogQL
D. GraphQL
Answer: B
