   What is the primary benefit of analyzing trace data across multiple services in a distributed system?

   • AIt eliminates the need for application logging
   • BIt allows you to see the end-to-end flow of a request and identify which service contributes the most latency
   • CIt automatically fixes performance issues in the services
   • DIt reduces the number of services needed in the architecture

   A retail company runs a microservices application on Azure Kubernetes Service (AKS). Support engineers report that when they investigate a slow checkout request, they can see the Azure Monitor metrics for each pod, but they cannot see the full path of the request across the front-end, payment, and inventory services. The application already emits logs and metrics to Azure Monitor. What should you do to enable end-to-end request tracing?

   • ACreate a Log Analytics workspace query that joins pod metrics by timestamp to reconstruct the request path.
   • BEnable Azure Monitor Container Insights and configure the AKS cluster to collect stdout/stderr logs from every pod.
   • CInstrument each service with the OpenTelemetry SDK and configure the exporters to send traces to Azure Monitor.
   • DAdd a Network Performance Monitor solution to the AKS cluster to trace network packets between services.

   A gaming company uses OpenTelemetry to trace player requests. They notice that the 'MatchmakingService' span shows a duration of 500 ms, but the 'PlayerProfileService' span (a child) shows a duration of 450 ms. The total request time is 2 seconds. What is the most likely explanation for the missing time?

   • AThe MatchmakingService is using asynchronous processing that is not captured by the span.
   • BThe sampling rate is set to 50%, so half of the spans are missing.
   • CThe PlayerProfileService span is using a different trace ID than the MatchmakingService span.
   • DThe MatchmakingService is waiting on an external dependency that is not instrumented with OpenTelemetry.

   A developer is new to OpenTelemetry and wants to understand the difference between traces and logs. They are building a distributed system and need to troubleshoot a specific user request. What should they use?

   • AUse metrics instead of traces and logs.
   • BUse only traces because they contain all the necessary information.
   • CUse only logs because they are easier to query.
   • DUse traces to follow the request across services and logs to get detailed error messages.
