Cloud Native Observability Fundamentals

1. What is the purpose of service mesh observability?

To manage container images

To monitor inter-service communication and traffic patterns

To replace Kubernetes networking

To encrypt all data at rest

2. What is the primary advantage of using pull-based metrics collection over push-based?

Lower latency

Server controls what data to scrape

Better for real-time streaming

Simpler to implement

3. Which component in OpenTelemetry handles data collection?

Exporter

Collector

Instrumentation

Propagator

4. True or False: Alerting should be based solely on metric thresholds.

True

False

Submit

6. What is a SLI (Service Level Indicator)?

A type of alerting rule

A measurable characteristic of service performance

A Kubernetes resource

A container image repository

7. Which of the following is a key benefit of structured logging?

Reduces disk space usage

Enables easier parsing and querying of logs

Improves application performance

Eliminates the need for monitoring

8. True or False: Observability requires collecting every piece of data generated by your system.

True

False

Submit

10. In Kubernetes, which component collects metrics from the kubelet?

Kube-controller-manager

Prometheus

Metrics server

Etcd

11. What is the primary purpose of observability in cloud native systems?

To eliminate all system errors

To gain insight into system behavior through metrics, logs, and traces

To reduce infrastructure costs

To replace traditional testing

12. Which metric type represents a single numerical value that can only increase or reset?

Gauge

Histogram

Counter

Summary

13. True or False: Metrics and logs serve the same purpose in observability.

True

False

Submit

15. What does distributed tracing help you identify?

CPU usage across nodes

Request paths and latency across microservices

Storage capacity issues

Network bandwidth utilization

16. Which tool is commonly used for centralized log aggregation in cloud native environments?

Grafana

Prometheus

Elasticsearch or Loki

Jaeger

17. What is a cardinality explosion in Prometheus?

Too many Prometheus servers

Uncontrolled growth of unique metric label combinations

Excessive alerting rules

High volume of time-series data

18. In Kubernetes, which resource type defines how Prometheus discovers targets?

ServiceMonitor

PodMonitor

Both ServiceMonitor and PodMonitor

MonitoringRule

19. What type of data does Prometheus primarily collect?

Structured logs

Time-series metrics

Distributed traces

Event streams

20. Which of the following is NOT part of the three pillars of observability?

Metrics

Logging

Tracing

Configuration management
