7. **What is Smartscape?**
Real-time, auto-generated topology map showing all dependencies between applications, services, processes, hosts, containers, and cloud services.
8. **What are Management Zones?**
Logical segmentation of the environment (e.g., Prod vs Dev, Team A vs Team B) to control data access and alerting scope.
9. **Difference between Dynatrace SaaS and Dynatrace Managed?**
SaaS = fully hosted and maintained by Dynatrace
Managed = customer-hosted cluster with full data residency control
10. **How does Dynatrace discover new services automatically?**
OneAgent detects new processes and containers, builds service flow using PurePath, and Smartscape updates topology instantly.
11. **What is Real User Monitoring (RUM)?**

SQL-like query language to explore logs, traces, metrics, events, and business data stored in Grail.
15. **Explain the difference between a Service and a Process Group in Dynatrace.**
Process Group = instances of the same application binary
Service = logical entry points (e.g., REST endpoints, message listeners) detected inside a process group.
16. **How do you create custom alerts in Dynatrace?**
Settings → Anomaly detection → Custom events for alerting → define metric + threshold + entity scope.
17. **What are Request Attributes?**
Captured data from method arguments, headers, or payloads that can be used for service splitting, filtering, and dashboards.
18. **What is a Problem in Dynatrace?**
A single actionable incident created by Davis AI after correlating multiple anomalies and impacts.
19. **What is the purpose of Calculated Service Metrics?**

20. **What is Session Replay?**
Pixel-perfect replay of real user sessions with masking of sensitive data for UX debugging.
21. **How does Dynatrace monitor Kubernetes?**
Dynatrace Operator deploys OneAgent on nodes and injects into pods; provides cluster, namespace, workload, pod, and container metrics + Cloud Native Full Stack view.
22. **What is the difference between Host Units (HU) and Davis Data Units (DDU)?**
HU = infrastructure monitoring consumption
DDU = logs, traces, RUM, synthetics, and metrics consumption
23. **What are Extensions in Dynatrace?**
Custom plugins (Extensions 2.0 uses WebAssembly) to pull in metrics from technologies not auto-detected (e.g., Kafka lag, F5, Cisco).
24. **What is Log Monitoring & Analytics in Dynatrace?**
Automatic log ingestion via OneAgent, enrichment with trace context, unlimited retention in Grail, and DQL queries.
25. **How do you tag entities automatically in Dynatrace?**
Settings → Tags → Auto-tagging rules based on process properties, environment variables, Kubernetes labels, cloud tags, etc.
### Advanced & Scenario-Based Questions (26–55+)
26. **How do you monitor AWS Lambda functions with Dynatrace?**
Serverless extension + OneAgent in Lambda layers or container images; provides PurePaths across Lambda invocations.
27. **How do you monitor Azure App Services or AWS Fargate?**
Site extensions (Azure) or task/container deployment with OneAgent operator (Fargate).
28. **Explain Service Flow and Backtrace.**
Service Flow = visual request journey between services
Backtrace = reverse path showing which downstream services were called.
29. **What is Multidimensional Analysis (MDA)?**
Ability to split any metric by any dimension (e.g., response time by country, device, OS, backend).
30. **How does Dynatrace support OpenTelemetry?**
Full support for traces, metrics, and logs via OTLP; auto-correlates with PurePath.
31. **What is the difference between Metric Events vs Log Events for alerting?**
Metric Events = threshold on metrics
Log Events = trigger when specific log pattern appears.
32. **How do you create an SLO in Dynatrace?**
Settings → SLO → create from metric selector or built-in templates (availability, latency, error budget).
33. **What is the User Action PurePath?**
End-to-end trace from browser click → frontend → backend services in one continuous trace.
34. **Explain the role of Environment ActiveGate vs Cluster ActiveGate.**
Environment AG = installed in customer environment for secure outbound
Cluster AG = internal to extend SaaS cluster capabilities.
35. **How do you reduce OneAgent traffic in large environments?**
