- A
AzureActivity | where TimeGenerated > ago(24h) | where OperationNameValue has_any ("Microsoft.Compute/virtualMachines/deallocate/action", "Microsoft.Compute/virtualMachines/powerOff/action")
This query filters the AzureActivity table to the last 24 hours and then matches the VM stop-related operations you need to review.
- B
AzureActivity | summarize count() by OperationNameValue
Why wrong: This query only counts operations and does not filter to the recent 24-hour window or the stop-related actions.
- C
AzureActivity | where ResourceType == "Microsoft.Compute/virtualMachines" | project TimeGenerated, ResourceGroup
Why wrong: This query lists VM-related records, but it does not restrict the results to stop or deallocate events.
- D
AzureActivity | sort by TimeGenerated asc
Why wrong: This query only sorts the data and does not filter for the time range or the VM operations you are investigating.
AZ-104 Monitor and Maintain Azure Resources Practice Question
This AZ-104 practice question tests your understanding of monitor and maintain azure resources. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
In Log Analytics, you need to find AzureActivity records for VM stop or deallocate operations from the last 24 hours. Which query should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AzureActivity | where TimeGenerated > ago(24h) | where OperationNameValue has_any ("Microsoft.Compute/virtualMachines/deallocate/action", "Microsoft.Compute/virtualMachines/powerOff/action")
Option A is correct because it uses the `has_any` operator to filter AzureActivity records for the exact operation names corresponding to VM stop (powerOff) and deallocate actions, and it restricts the time range to the last 24 hours using `ago(24h)`. This directly matches the requirement to find VM stop or deallocate operations within the specified timeframe.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the `has_any` operator with `contains` or `in`, or forget to include the time filter, leading them to select options that either don't filter by operation type or don't restrict the time window.
Detailed technical explanation
How to think about this question
The `has_any` operator in Kusto Query Language (KQL) performs a case-insensitive substring match against a list of strings, which is efficient for filtering operation names that contain the specified action identifiers. The `ago(24h)` function returns a datetime value representing 24 hours before the current time, and when used in a `where` clause with `TimeGenerated`, it creates a time-bounded query that leverages the table's time-partitioning for faster execution. In real-world scenarios, you might also need to consider that `powerOff` is the operation for stopping a VM while `deallocate` releases the underlying hardware, and both are distinct actions in Azure Resource Manager.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
