Question 920
An operations team needs to query log records using Kusto Query Language. The team observes: The workspace query returns no data despite activity in the app. Which underlying mistake most directly explains the reported symptom?
- The required monitoring data source was not configured.
- The monitoring plan excluded platform health events.
- The team did not review Azure Advisor recommendations.
- Diagnostic logs were not being routed to that workspace.
Explanation
Correct Answer
D:Diagnostic logs were not being routed to that workspace. That explains the symptom: The workspace query returns no data despite activity in the app. The targeted corrective action is: Send relevant logs to the intended workspace and run a KQL query.
Incorrect Answers
A:This cause is consistent with a different issue: The dashboard is empty because no diagnostics are collected. It does not account for the reported symptom here: The workspace query returns no data despite activity in the app.
B:The alternate mechanism would more directly produce this other failure: A regional outage triggers no alert because only CPU thresholds were configured. The current incident instead involves: The workspace query returns no data despite activity in the app.
C:That explanation belongs to a different fault pattern: A cost issue remains unnoticed despite available rightsizing findings. It does not explain why the workspace query returns no data despite activity in the app.
Question 921
A DevOps team wants an email when VM CPU use exceeds a defined threshold. What is the most appropriate cloud concept or service for this need?
- Use Azure Service Health planned maintenance information.
- Use Application Insights dependency telemetry and distributed tracing.
- Use Azure Advisor for personalized cost, performance and reliability recommendations.
- Use Azure Monitor alerts with an appropriate rule and action group.
Explanation
Correct Answer
D:Use Azure Monitor alerts with an appropriate rule and action group. The governing requirement is: A DevOps team wants an email when VM CPU use exceeds a defined threshold. This solution specifically supports the outcome that a threshold test fires the alert and delivers the configured notification.
Incorrect Answers
A:This design is appropriate for a different requirement: A resource owner wants planned Azure maintenance announcements relevant to a region. Here the decisive outcome must instead be: A threshold test fires the alert and delivers the configured notification.
B:That concept addresses this separate situation: A system administrator needs to identify which application dependency causes high request latency. It does not by itself establish the result required here: A threshold test fires the alert and delivers the configured notification.
C:This option solves a different planning problem: A team asks about Azure Advisor suggestions to right-size underutilized resources. The current acceptance criterion is specific: A threshold test fires the alert and delivers the configured notification.
Question 922
A DevOps team wants an email when VM CPU use exceeds a defined threshold. What should the team configure or perform to implement the correct approach?
- Assign recommendation owners and verify actual remediation after approval.
- Set diagnostic settings to a workspace and query the correct time window.
- Enable request and exception collection and inspect correlated traces.
- Create a metric alert and connect it to the intended action group.
Explanation
Correct Answer
D:Create a metric alert and connect it to the intended action group. The implementation operationalizes this design choice: Use Azure Monitor alerts with an appropriate rule and action group. Acceptance should demonstrate: A threshold test fires the alert and delivers the configured notification.
Incorrect Answers
A:This setup is relevant to another workload: A security reviewer wants to know whether Azure Advisor directly fixes every identified issue. The current configuration must instead achieve: A threshold test fires the alert and delivers the configured notification.
B:That action implements a different requirement: An auditor wants to review resource diagnostic events for the last week. It does not establish the required result in this case: A threshold test fires the alert and delivers the configured notification.
C:This change would be appropriate under a different condition: A web service's request error rate rises while Azure infrastructure metrics remain healthy. Here it would not validate: A threshold test fires the alert and delivers the configured notification.
Question 923
A DevOps team wants an email when VM CPU use exceeds a defined threshold. Which evidence best confirms the requirement is being met?
- A threshold test fires the alert and delivers the configured notification.
- Request performance and dependency traces appear for sample traffic.
- A high-memory event is recorded as a resource metric, not a global service outage.
- Actionable reliability suggestions appear for the tenant.
Explanation
Correct Answer
A:A threshold test fires the alert and delivers the configured notification. That directly tests the stated requirement: A DevOps team wants an email when VM CPU use exceeds a defined threshold. It contrasts with the observed failure: The alert condition triggers but no email reaches the responder.
Incorrect Answers
B:That check tests another control: An app owner wants request latency, failure and dependency traces for a web application. The decisive result for this workload is: A threshold test fires the alert and delivers the configured notification.
C:The test is relevant when a new engineer confuses Azure Service Health with monitoring one VM's memory. It cannot establish the specified acceptance result: A threshold test fires the alert and delivers the configured notification.
D:This observation is evidence for a separate scenario: A business manager wants to see specific recommendations for Azure service reliability. It does not test the necessary outcome here: A threshold test fires the alert and delivers the configured notification.
Question 924
A DevOps team wants an email when VM CPU use exceeds a defined threshold. The team observes: The alert condition triggers but no email reaches the responder. What is the most likely cause of the observed failure?
- The monitoring plan excluded platform health events.
- Diagnostic logs were not being routed to that workspace.
- The alert rule lacks a working action-group notification configuration.
- Service Health planned-maintenance notifications were not configured.
Explanation
Correct Answer
C:The alert rule lacks a working action-group notification configuration. That explains the symptom: The alert condition triggers but no email reaches the responder. The targeted corrective action is: Create a metric alert and connect it to the intended action group.
Incorrect Answers
A:This cause is consistent with a different issue: A regional outage triggers no alert because only CPU thresholds were configured. It does not account for the reported symptom here: The alert condition triggers but no email reaches the responder.
B:The alternate mechanism would more directly produce this other failure: The workspace query returns no data despite activity in the app. The current incident instead involves: The alert condition triggers but no email reaches the responder.
D:This cause is consistent with a different issue: Maintenance affects an application without a configured notice path. It does not account for the reported symptom here: The alert condition triggers but no email reaches the responder.
Question 925
An app owner wants request latency, failure and dependency traces for a web application. Which architectural decision meets the described priority?
- Connect alert action groups to supported automation targets where appropriate.
- Use Azure Service Health planned maintenance information.
- Use Log Analytics query capability for collected resource logs.
- Use Azure Monitor Application Insights for application performance monitoring.
Explanation
Correct Answer
D:Use Azure Monitor Application Insights for application performance monitoring. The governing requirement is: An app owner wants request latency, failure and dependency traces for a web application. This solution specifically supports the outcome that request performance and dependency traces appear for sample traffic.
Incorrect Answers
A:This design is appropriate for a different requirement: An operator wants automated remediation after certain Azure Monitor alerts. Here the decisive outcome must instead be: Request performance and dependency traces appear for sample traffic.
B:That concept addresses this separate situation: A resource owner wants planned Azure maintenance announcements relevant to a region. It does not by itself establish the result required here: Request performance and dependency traces appear for sample traffic.
C:This option solves a different planning problem: An auditor wants to review resource diagnostic events for the last week. The current acceptance criterion is specific: Request performance and dependency traces appear for sample traffic.
Question 926
An app owner wants request latency, failure and dependency traces for a web application. Which configuration or operating action most directly puts that decision into practice?
- Instrument the eligible app with Application Insights telemetry collection.
- Configure diagnostic settings and applicable retention policies.
- Review Advisor recommendations and validate impact before changes.
- Adjust appropriate threshold, lookback and severity settings after validation.
Explanation
Correct Answer
A:Instrument the eligible app with Application Insights telemetry collection. The implementation operationalizes this design choice: Use Azure Monitor Application Insights for application performance monitoring. Acceptance should demonstrate: Request performance and dependency traces appear for sample traffic.
Incorrect Answers
B:That action implements a different requirement: A compliance analyst wants to retain Azure diagnostic logs for later KQL search. It does not establish the required result in this case: Request performance and dependency traces appear for sample traffic.
C:This change would be appropriate under a different condition: A team asks about Azure Advisor suggestions to right-size underutilized resources. Here it would not validate: Request performance and dependency traces appear for sample traffic.
D:This setup is relevant to another workload: A team receives too many low-value alerts from brief metric spikes. The current configuration must instead achieve: Request performance and dependency traces appear for sample traffic.
Question 927
An app owner wants request latency, failure and dependency traces for a web application. Which observation is the strongest acceptance test for this scenario?
- Log queries return recorded events from the required retention period.
- Incidents correspond more closely to sustained actionable conditions.
- Operators can chart CPU percentage and query detailed events separately.
- Request performance and dependency traces appear for sample traffic.
Explanation
Correct Answer
D:Request performance and dependency traces appear for sample traffic. That directly tests the stated requirement: An app owner wants request latency, failure and dependency traces for a web application. It contrasts with the observed failure: Only host CPU metrics exist and no app request spans are visible.
Incorrect Answers
A:This observation is evidence for a separate scenario: An auditor wants to review resource diagnostic events for the last week. It does not test the necessary outcome here: Request performance and dependency traces appear for sample traffic.
B:That check tests another control: A team receives too many low-value alerts from brief metric spikes. The decisive result for this workload is: Request performance and dependency traces appear for sample traffic.
C:The test is relevant when a developer wants to distinguish Azure Monitor metrics from logs. It cannot establish the specified acceptance result: Request performance and dependency traces appear for sample traffic.
Question 928
An app owner wants request latency, failure and dependency traces for a web application. The team observes: Only host CPU metrics exist and no app request spans are visible. Which planning or configuration error best accounts for this result?
- Application-level telemetry was not instrumented.
- Retention was not configured to match audit requirements.
- Individual resource health was confused with broad Service Health notices.
- A scheduled alert rule or action group was not established.
Explanation
Correct Answer
A:Application-level telemetry was not instrumented. That explains the symptom: Only host CPU metrics exist and no app request spans are visible. The targeted corrective action is: Instrument the eligible app with Application Insights telemetry collection.
Incorrect Answers
B:The alternate mechanism would more directly produce this other failure: Required records age out earlier than the audit period. The current incident instead involves: Only host CPU metrics exist and no app request spans are visible.
C:That explanation belongs to a different fault pattern: The team checks only global incidents for a single VM outage. It does not explain why only host CPU metrics exist and no app request spans are visible.
D:This cause is consistent with a different issue: The query works manually but never sends an automated incident alert. It does not account for the reported symptom here: Only host CPU metrics exist and no app request spans are visible.
Question 929
A team asks about Azure Advisor suggestions to right-size underutilized resources. Which Azure or cloud concept most directly matches the requirement?
- Use Resource Health for supported individual-resource health status.
- Use the Azure Service Health service issues view for subscribed regional incidents.
- Use a Log Analytics workspace for supported centralized log queries.
- Use Azure Advisor for personalized cost, performance and reliability recommendations.
Explanation
Correct Answer
D:Use Azure Advisor for personalized cost, performance and reliability recommendations. The governing requirement is: A team asks about Azure Advisor suggestions to right-size underutilized resources. This solution specifically supports the outcome that the team gets supported optimization suggestions based on its resources.
Incorrect Answers
A:This design is appropriate for a different requirement: A service desk wants to view resource outage notifications in the Azure portal. Here the decisive outcome must instead be: The team gets supported optimization suggestions based on its resources.
B:That concept addresses this separate situation: A company needs to know if a cloud region is impacted by a Microsoft outage. It does not by itself establish the result required here: The team gets supported optimization suggestions based on its resources.
C:This option solves a different planning problem: An operations team needs to query log records using Kusto Query Language. The current acceptance criterion is specific: The team gets supported optimization suggestions based on its resources.
Question 930
A team asks about Azure Advisor suggestions to right-size underutilized resources. Which implementation step would best fulfill the stated requirement?
- Filter Service Health to relevant subscriptions, services and regions.
- Enable appropriate diagnostic and metric collection for target resources.
- Review Advisor recommendations and validate impact before changes.
- Choose metric charts for CPU trends and log queries for diagnostic records.
Explanation
Correct Answer
C:Review Advisor recommendations and validate impact before changes. The implementation operationalizes this design choice: Use Azure Advisor for personalized cost, performance and reliability recommendations. Acceptance should demonstrate: The team gets supported optimization suggestions based on its resources.
Incorrect Answers
A:This setup is relevant to another workload: A company needs to know if a cloud region is impacted by a Microsoft outage. The current configuration must instead achieve: The team gets supported optimization suggestions based on its resources.
B:That action implements a different requirement: An application team wants telemetry on CPU, requests and resource health. It does not establish the required result in this case: The team gets supported optimization suggestions based on its resources.
D:This setup is relevant to another workload: A developer wants to distinguish Azure Monitor metrics from logs. The current configuration must instead achieve: The team gets supported optimization suggestions based on its resources.
