Question 980 A support engineer manually queries error logs and assumes stakeholders will automatically be notified of future matches. What extra configuration is needed? A VM image label indicating Error An Azure resource lock on the workspace A suitable Azure Monitor log alert rule and action group Create a saved log query but do not create an alert rule or action group Explanation Correct Answer C:Manual KQL queries do not create recurring alert notifications by themselves. Incorrect Answers A:Metadata can't send alert emails. B:Locks don't evaluate query results. D:Saved queries support investigation; notifications require separate alert evaluation and routing configuration.
Question 981 A company wants to correlate diagnostic events from a VPN Gateway and an App Service in one investigation. Which design helps? Keep all diagnostic output isolated and never export anything Use a common VM availability set for the two services Give the applications a shared dashboard title without routing data to a common workspace Route supported logs from both sources to an accessible shared analytic workspace Explanation Correct Answer D:Central collection permits time-aligned queries across services. Incorrect Answers A:Silos make correlation harder. B:A VPN gateway and App Service don't share availability-set membership. C:Dashboard naming does not cause supported log records from separate resources to be ingested together.
Question 982 An incident occurred last night, but diagnostic settings were enabled only this morning. What limitation should investigators understand? Enabling logs now automatically reconstructs every past network packet A budget alert can reconstruct all missing exception stacks Assume redeploying the app restores all previously uncollected production log events Collection normally cannot recreate all previously uncollected resource logs retrospectively Explanation Correct Answer D:Logging must be configured in time to retain needed evidence. Incorrect Answers A:Future collection doesn't imply historical packet recovery. B:Costs don't provide past app exceptions. C:A new deployment cannot recreate telemetry that was never collected or retained during the incident.
Question 983 A web application is running on Azure, and its team wants request duration, failures and dependencies. Which Azure Monitor component is relevant? A VM availability set Azure Data Box Application Insights Review only infrastructure CPU charts to diagnose application dependency failures Explanation Correct Answer C:Application Insights collects and analyzes supported application performance telemetry. Incorrect Answers A:Fault placement is not app instrumentation. B:Offline transfer doesn't observe live web requests. D:Host metrics may show resource pressure but do not replace request and dependency telemetry in Application Insights.
Question 984 Customers report intermittent HTTP 500 errors, but infrastructure CPU looks normal. What telemetry is most useful? Check only the platform deployment success status to find failed HTTP requests Only a subscription cost budget Application Insights failed request and exception diagnostics Only the VM's disk tier Explanation Correct Answer C:App-level telemetry can expose errors that resource utilization alone misses. Incorrect Answers A:Deployments can succeed while application requests fail; request telemetry is the relevant evidence. B:Spending alerts don't contain the HTTP exception. D:Disk speed doesn't identify the failing method.
Question 985 A website responds slowly because SQL calls take several seconds. Which Application Insights capability helps narrow the bottleneck? Only a VM availability set's fault domain Only a billing currency chart Only a resource group's tag list Dependency telemetry showing downstream call duration and failures Explanation Correct Answer D:Database dependency spans can reveal time spent outside the web process. Incorrect Answers A:Placement doesn't measure SQL call latency. B:Costs aren't service dependency timings. C:Metadata doesn't trace requests.
Question 986 A customer request passes through multiple instrumented components, and developers need an end-to-end timeline. What telemetry concept should they use? An Azure Backup restore point Distributed tracing with correlated operation identifiers Rely only on independent per-service CPU metrics with no request correlation A static diagram of resource names only Explanation Correct Answer B:Correlated spans help follow one transaction across service boundaries. Incorrect Answers A:Recovery points don't trace a live request. C:CPU measurements cannot reconstruct a cross-service request path or its dependency spans. D:Topology alone doesn't show actual transaction latency.
Question 987 An operations team wants to detect whether its public website responds successfully from external test locations. Which feature may help? Application Insights availability tests, where supported Only Blob access-tier monitoring Only a VM resource lock Look at historical usage trends without configuring an active availability test Explanation Correct Answer A:Availability monitoring can periodically probe an endpoint from configured locations. Incorrect Answers B:Object temperature doesn't test a site URL. C:Locks don't issue HTTP probes. D:Usage trends do not themselves probe an endpoint at defined intervals to detect outages.
Question 988 A product team instruments client usage but wants to avoid collecting personally sensitive fields unnecessarily. What design consideration is important? Use only a resource tag named Compliant Configure telemetry collection and data-handling practices to minimize sensitive information Log all authentication tokens because the app is internal Make every telemetry workspace public for convenience Explanation Correct Answer B:Application instrumentation should respect privacy and organizational policies. Incorrect Answers A:Metadata cannot validate telemetry privacy. C:Internal users still need secret protection. D:Public exposure is not a privacy control.
Question 989 A freshly deployed API shows no request telemetry despite handling live traffic. What should developers investigate? Application Insights instrumentation, connection configuration and telemetry ingestion Only an unrelated subscription budget Only the VM availability zone Increase the App Service plan size without enabling supported application instrumentation Explanation Correct Answer A:The application must be correctly instrumented or connected for supported telemetry to appear. Incorrect Answers B:Cost management doesn't capture request spans. C:Zone selection isn't instrumentation configuration. D:More compute does not automatically supply the missing request or dependency telemetry.
Question 990 A high-traffic application sends enormous telemetry volume to monitoring and needs to manage ingestion while retaining useful trends. Which technique might help? Increase log-retention time as the only method of reducing ingestion volume Use an availability set to compress events Delete every error event indiscriminately without metrics Supported application telemetry sampling with awareness of analysis trade-offs Explanation Correct Answer D:Sampling can reduce volume but may omit rare events. Incorrect Answers A:Longer retention changes storage economics, not the rate at which verbose telemetry is submitted. B:Compute placement isn't telemetry sampling. C:Suppressing all failures destroys incident evidence.
