Sample questions

Try each one before opening the answer. Every option is explained, with the Microsoft documentation page that proves it.

Question 1 · choose 1

An admin wants personalized recommendations for a subscription across reliability, security, performance, operational excellence and cost, each with a suggested action. Which service provides them?

  1. AAzure Advisor
  2. BAzure Service Health
  3. CAzure Policy
  4. DAzure Monitor
Show the answer and why
  • AAzure Advisor

    Correct

    Advisor evaluates your resources and recommends improvements in reliability, security, performance, operational excellence and cost.

  • BAzure Service Health

    Incorrect

    Service Health reports on the health of Azure services, not on improvements to your own resources.

  • CAzure Policy

    Incorrect

    Azure Policy reports compliance with the rules you assign, not best-practice recommendations across these five areas.

  • DAzure Monitor

    Incorrect

    Azure Monitor doesn't produce best-practice recommendations across these five areas.

Azure Advisor is a personalized best-practices guide built into the portal. Its recommendations fall into five categories, and each comes with an action you can take now, postpone or dismiss.

Question 2 · choose 1

An operations team wants an email whenever Azure posts a service issue or planned maintenance that affects the Azure services and regions the company actually uses. Which tool should it configure?

  1. AThe Azure status page
  2. BAzure Service Health
  3. CAzure Resource Health
  4. DAzure Advisor
Show the answer and why
  • AThe Azure status page

    Incorrect

    The status page shows the health of all Azure services in all regions and isn't tailored to the company's resources.

  • BAzure Service Health

    Correct

    Service Health focuses on the services and regions you use and can alert you about outages, planned maintenance and advisories.

  • CAzure Resource Health

    Incorrect

    Resource Health doesn't cover service issues and maintenance across the company's services and regions.

  • DAzure Advisor

    Incorrect

    Advisor doesn't post notices of service incidents or maintenance.

Service Health is the personalized view of the Azure services and regions you use, showing outages, planned maintenance and health advisories, and it can alert you automatically. The Azure status page covers all of Azure, not the company's own footprint.

Question 3 · choose 1

A team wants an alert when the text PaymentTimeout appears in the application logs of any of 12 VMs more than five times in 10 minutes. The logs are collected in a Log Analytics workspace. Which kind of alert rule fits?

  1. AA log search alert rule
  2. BA metric alert rule on the VMs' CPU percentage
  3. CAn activity log alert rule
  4. DA Service Health alert rule
Show the answer and why
  • AA log search alert rule

    Correct

    Log search alerts run a Log Analytics query at a set frequency, so they can count an error pattern across many resources.

  • BA metric alert rule on the VMs' CPU percentage

    Incorrect

    A CPU threshold can't detect a specific error string in the logs.

  • CAn activity log alert rule

    Incorrect

    An activity log alert can't run a query that counts PaymentTimeout lines in the workspace's application logs.

  • DA Service Health alert rule

    Incorrect

    Service Health alerts are about the Azure platform's own health, not your application's errors.

Azure Monitor alerts can be metric-based or log-based. A log search alert runs a query over the logs collected in a Log Analytics workspace, which is how to watch for a specific error pattern across multiple resources.

Question 4 · choose 2

A team turns on Application Insights for its web application. Which two kinds of data will Application Insights give them about the app? (Choose TWO.)

  1. APlanned maintenance scheduled for the app's Azure region
  2. BRequest rates, response times and failure rates
  3. CThe app's costs grouped by resource group
  4. DRecommendations to resize underused VMs
  5. ECalls the app makes to dependencies and how long they take
Show the answer and why
  • APlanned maintenance scheduled for the app's Azure region

    Incorrect

    Planned maintenance notices aren't application telemetry; Azure publishes them through its own health service.

  • BRequest rates, response times and failure rates

    Correct

    Application Insights monitors request rates, response times and failure rates for the app.

  • CThe app's costs grouped by resource group

    Incorrect

    Cost data isn't application telemetry; it comes from Azure's billing tools.

  • DRecommendations to resize underused VMs

    Incorrect

    Rightsizing advice for VMs isn't application telemetry; it comes from a separate Azure service.

  • ECalls the app makes to dependencies and how long they take

    Correct

    Application Insights tracks dependency calls, such as to databases or APIs, and their performance.

Application Insights, a feature of Azure Monitor, watches the performance and usage of web apps wherever they run: request rates, response times and failure rates, dependency calls, page load times and sessions, and server performance counters.

Question 5 · choose 1

One VM stopped responding. An engineer wants to know whether that specific VM has a problem and whether the cause is on Azure's side or in the company's own configuration. Which view should she check?

  1. AAzure status page
  2. BAzure Advisor
  3. CCost analysis
  4. DResource Health
Show the answer and why
  • AAzure status page

    Incorrect

    The status page shows global health across all services and regions, not the state of one VM.

  • BAzure Advisor

    Incorrect

    Advisor makes best-practice recommendations; it doesn't diagnose a current outage.

  • CCost analysis

    Incorrect

    Cost analysis shows spending and has nothing to say about a VM's health.

  • DResource Health

    Correct

    Resource Health reports on individual resources, whether they're running normally and whether an issue is on Azure's side or yours.

Azure Service Health has three views that narrow from global to specific, from the Azure status page down to Resource Health for individual resources such as a particular VM.

Question 6 · choose 1

An engineer wants to find all errors her app recorded in the last hour and chart how often they've occurred over the past week, using the data Azure Monitor collects. Which tool in the Azure portal should she use?

  1. AAzure Advisor
  2. BAzure Service Health
  3. CLog Analytics
  4. DThe Azure pricing calculator
Show the answer and why
  • AAzure Advisor

    Incorrect

    Advisor offers recommendations; it doesn't query collected logs.

  • BAzure Service Health

    Incorrect

    Service Health reports Azure incidents and maintenance, not your app's own errors.

  • CLog Analytics

    Correct

    Log Analytics is where you write and run queries against data Azure Monitor collects, from simple filters to trend visualizations.

  • DThe Azure pricing calculator

    Incorrect

    The pricing calculator estimates costs, not log data.

Azure Monitor gathers logs and metrics from applications, operating systems and networks. Log Analytics is the portal tool for querying that data, whether a simple filter such as errors in the last hour or advanced analytics charting trends over time.

Question 7 · choose 1

An admin creates an Azure Monitor alert rule for a VM. The alert fires as expected, but nobody receives an email or text message. Which part of the alert setup decides who is notified and what happens next?

  1. AThe alert rule's condition
  2. BThe Log Analytics workspace that stores the data
  3. CThe action group attached to the alert rule
  4. DAn Azure Monitor workbook for the VM
Show the answer and why
  • AThe alert rule's condition

    Incorrect

    The condition decides when the alert fires, and here it's firing as expected.

  • BThe Log Analytics workspace that stores the data

    Incorrect

    The workspace holds collected data; it doesn't send notifications.

  • CThe action group attached to the alert rule

    Correct

    The action group controls who gets notified and which actions run when the alert fires.

  • DAn Azure Monitor workbook for the VM

    Incorrect

    Workbooks don't send notifications or run actions when an alert fires.

An Azure Monitor alert has two parts: an alert rule that specifies the condition and an action group that controls who gets notified and what happens next, such as an email, a text message or an automated workflow.

Question 8 · choose 1

Azure Advisor keeps recommending a larger size for one test VM that the team deliberately keeps small. The team wants that one recommendation off its list of active recommendations, while still seeing Advisor's other recommendations for the VM and its resource group. What should it do?

  1. AAdd a tag that marks the VM as a test machine
  2. BCreate a Service Health alert for the VM's region
  3. CDismiss or postpone that recommendation in Advisor
  4. DExclude the VM's resource group in Advisor's configuration
Show the answer and why
  • AAdd a tag that marks the VM as a test machine

    Incorrect

    Tags add metadata for organizing, reporting and automation; a tag alone doesn't change which Advisor recommendations are active.

  • BCreate a Service Health alert for the VM's region

    Incorrect

    Service Health alerts tell you about Azure service events in the regions you use; they don't affect Advisor recommendations.

  • CDismiss or postpone that recommendation in Advisor

    Correct

    Advisor lets you postpone or dismiss a recommendation, which moves it out of the active list while the rest stay active.

  • DExclude the VM's resource group in Advisor's configuration

    Incorrect

    Excluding the resource group would hide every recommendation for it, including the ones the team still wants to see.

Advisor recommendations have a status: active, postponed, dismissed or completed. Postponing or dismissing a recommendation that doesn't apply removes it from the active list without changing the resource, while Advisor's configuration can exclude whole subscriptions or resource groups when no recommendations are wanted for them.
