Question 690
A custom discount capability needs a measurable signal when users discover, activate and successfully use it. The developer recommends the following change: Emit purposeful custom feature telemetry such as usage, uptake and error signals. Which technical explanation most directly justifies it in this case?
- Structured telemetry dimensions let investigators narrow events to a deployment and correlate performance or errors
- Custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal
- Performance work should target observed long-running calls rather than speculative components
- Environment-level telemetry sends service operation events to Azure Application Insights for monitoring and troubleshooting
Explanation
Correct Answer
B:Custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal. It connects the proposed action to the exact failure or requirement—A custom discount capability needs a measurable signal when users discover, activate and successfully use it. Confirmation would be sample business actions produce identifiable feature events with useful non-sensitive dimensions.
Incorrect Answers
A:That mechanism explains why the alternative action—analyze application insights traces using kql filters for environment, app id, version and time—helps in another case. It does not justify the proposed fix here; custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal. The distinguishing requirement is: A custom discount capability needs a measurable signal when users discover, activate and successfully use it.
C:That mechanism explains why the alternative action—use timing and performance telemetry to locate the measured slow operation before optimizing—helps in another case. It does not justify the proposed fix here; custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal. The distinguishing requirement is: A custom discount capability needs a measurable signal when users discover, activate and successfully use it.
D:That mechanism explains why the alternative action—enable and verify environment-level telemetry to the intended application insights resource—helps in another case. It does not justify the proposed fix here; custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal. The distinguishing requirement is: A custom discount capability needs a measurable signal when users discover, activate and successfully use it.
Question 691
A custom discount capability needs a measurable signal when users discover, activate and successfully use it. The team implemented a change aligned with this plan: Emit purposeful custom feature telemetry such as usage, uptake and error signals. Which acceptance result specifically verifies that the reported problem is resolved?
- A filtered query returns the known failed operation in the correct release window without mixing other apps
- Instrumented measurements identify a slow code path and show reduced duration after a controlled fix
- Sample business actions produce identifiable feature events with useful non-sensitive dimensions
- Test operations produce expected environment events in the designated resource and environment dimension
Explanation
Correct Answer
C:Sample business actions produce identifiable feature events with useful non-sensitive dimensions. This is stronger than an unrelated health check because the desired design action is emit purposeful custom feature telemetry such as usage, uptake and error signals, and custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal. The local requirement is: A custom discount capability needs a measurable signal when users discover, activate and successfully use it.
Incorrect Answers
A:This would verify analyze application insights traces using kql filters for environment, app id, version and time, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: A custom discount capability needs a measurable signal when users discover, activate and successfully use it. The decisive local proof is sample business actions produce identifiable feature events with useful non-sensitive dimensions.
B:This would verify use timing and performance telemetry to locate the measured slow operation before optimizing, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: A custom discount capability needs a measurable signal when users discover, activate and successfully use it.

Question 692
A custom discount capability needs a measurable signal when users discover, activate and successfully use it. A targeted trial still reproduces the original gap after the team attempted this change: Emit purposeful custom feature telemetry such as usage, uptake and error signals. Which repair directly addresses the remaining defect?
- Correct the KQL dimensions and time window so relevant traces are included and unrelated ones excluded
- Reproduce with telemetry, identify the expensive operation and optimize that path before retesting
- Correct the environment Application Insights connection settings and ingestion access then verify signals
- Instrument the missing business paths with appropriate feature telemetry and exclude confidential field values
Explanation
Correct Answer
D:Instrument the missing business paths with appropriate feature telemetry and exclude confidential field values. This directly addresses the remaining defect for the requirement—A custom discount capability needs a measurable signal when users discover, activate and successfully use it. It restores the mechanism described here: custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal.
Incorrect Answers
A:This correction is for the separate condition: A regional operations team needs to compare latency for two app versions using structured telemetry fields. It would not directly restore the intended behavior in this situation: A custom discount capability needs a measurable signal when users discover, activate and successfully use it. Here, instrument the missing business paths with appropriate feature telemetry and exclude confidential field values, because custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal.
B:This correction is for the separate condition: A warehouse application sometimes times out and engineers guess which database operation is expensive. It would not directly restore the intended behavior in this situation: A custom discount capability needs a measurable signal when users discover, activate and successfully use it. Here, instrument the missing business paths with appropriate feature telemetry and exclude confidential field values, because custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal.
C:This correction is for the separate condition: A support team wants error and latency signals from an on-premises Business Central instance into Azure Monitor. It would not directly restore the intended behavior in this situation: A custom discount capability needs a measurable signal when users discover, activate and successfully use it. Here, instrument the missing business paths with appropriate feature telemetry and exclude confidential field values, because custom feature telemetry records application-specific behavior that generic infrastructure events may not reveal.
