A VM named VM01 stopped sending Heartbeat records to Log Analytics 15 minutes ago. Which KQL query should you run to confirm the VM's recent heartbeat entries?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Heartbeat | where Computer == "VM01" and TimeGenerated > ago(15m)
This query filters the Heartbeat table for VM01 entries from the last 15 minutes.
B
Distractor review
AzureActivity | where ResourceProviderValue == "Microsoft.Compute/virtualMachines"
This query reads activity logs, not heartbeat data from Log Analytics.
C
Distractor review
Heartbeat | summarize count() by Computer
This query counts heartbeats, but it does not limit results to the last 15 minutes.
D
Distractor review
Perf | where CounterName == "% Processor Time"
This query looks at performance counters, not the heartbeat table used for agent health.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Heartbeat | where Computer == "VM01" and TimeGenerated > ago(15m) — The Heartbeat table is used to verify that a machine is still reporting into Log Analytics. Filtering by Computer isolates VM01, and using TimeGenerated > ago(15m) limits the results to the last 15 minutes. This makes the query suitable for quickly checking whether recent heartbeat records exist before building an alert or investigating an agent communication issue. Why others are wrong: AzureActivity contains management events such as create and delete actions, not heartbeat telemetry. The summarize query only counts rows and does not verify recency. The Perf table stores performance metrics like processor time, which is different from the heartbeat signal used to confirm connectivity and agent reporting.
