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?

  1. The required monitoring data source was not configured.
  2. The monitoring plan excluded platform health events.
  3. The team did not review Azure Advisor recommendations.
  4. 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?

  1. Use Azure Service Health planned maintenance information.
  2. Use Application Insights dependency telemetry and distributed tracing.
  3. Use Azure Advisor for personalized cost, performance and reliability recommendations.
  4. 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?

  1. Assign recommendation owners and verify actual remediation after approval.
  2. Set diagnostic settings to a workspace and query the correct time window.
  3. Enable request and exception collection and inspect correlated traces.
  4. 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?

  1. A threshold test fires the alert and delivers the configured notification.
  2. Request performance and dependency traces appear for sample traffic.
  3. A high-memory event is recorded as a resource metric, not a global service outage.
  4. 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?

  1. The monitoring plan excluded platform health events.
  2. Diagnostic logs were not being routed to that workspace.
  3. The alert rule lacks a working action-group notification configuration.
  4. 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?

  1. Connect alert action groups to supported automation targets where appropriate.
  2. Use Azure Service Health planned maintenance information.
  3. Use Log Analytics query capability for collected resource logs.
  4. 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?

  1. Instrument the eligible app with Application Insights telemetry collection.
  2. Configure diagnostic settings and applicable retention policies.
  3. Review Advisor recommendations and validate impact before changes.
  4. 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?

  1. Log queries return recorded events from the required retention period.
  2. Incidents correspond more closely to sustained actionable conditions.
  3. Operators can chart CPU percentage and query detailed events separately.
  4. 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?

  1. Application-level telemetry was not instrumented.
  2. Retention was not configured to match audit requirements.
  3. Individual resource health was confused with broad Service Health notices.
  4. 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?

  1. Use Resource Health for supported individual-resource health status.
  2. Use the Azure Service Health service issues view for subscribed regional incidents.
  3. Use a Log Analytics workspace for supported centralized log queries.
  4. 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?

  1. Filter Service Health to relevant subscriptions, services and regions.
  2. Enable appropriate diagnostic and metric collection for target resources.
  3. Review Advisor recommendations and validate impact before changes.
  4. 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.
