The answer is data sources, alert rules, and visualization tools. These three components are required for a complete Azure Monitor solution because data sources collect metrics and logs from Azure resources and applications, alert rules define conditions that trigger proactive notifications when thresholds are crossed, and visualization tools like dashboards or workbooks allow you to analyze and interpret the collected data. Without alert rules, your monitoring data remains passive and cannot automatically inform you of issues, while without visualization, raw data is difficult to act upon. On the AZ-305 exam, this tests your understanding of the Azure Monitor architecture and the distinction between optional features and core pillars. A common trap is selecting only data sources and alerts, forgetting that a complete solution must also present the data in a consumable way. Memory tip: think of the three pillars as "Collect, Alert, Display" — you need all three for a full monitoring loop.
AZ-305 Practice Question: Design identity, governance, and monitoring solutions
This AZ-305 practice question tests your understanding of design identity, governance, and monitoring solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Which THREE components are required to implement a complete monitoring solution with Azure Monitor? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Alert rules to notify on conditions
Alert rules (C) are a core component of a complete monitoring solution because they define conditions that trigger notifications or automated actions when monitored metrics or log data cross thresholds. Without alert rules, collected data remains passive and cannot proactively inform administrators of issues, making the solution incomplete.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Application Insights for every application
Why it's wrong here
Application Insights is optional, not required for all monitoring.
✗
Azure Policy assignments
Why it's wrong here
Azure Policy is for compliance, not monitoring.
✓
Alert rules to notify on conditions
Why this is correct
Alerts are essential for proactive monitoring.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse optional monitoring tools (like Application Insights) with mandatory components, or they mistakenly think governance tools (like Azure Policy) are part of the monitoring pipeline, when in fact the three required components are data sources, a Log Analytics workspace, and alert rules.
Detailed technical explanation
How to think about this question
Azure Monitor's architecture relies on a pipeline: data sources (E) send metrics and logs to a Log Analytics workspace (D), where they are stored and queried; alert rules (C) then evaluate these logs or metrics against thresholds (e.g., using KQL queries or metric alerts) to trigger actions like email, SMS, or webhooks. A common subtlety is that alert rules can use dynamic thresholds that adapt to historical patterns, reducing noise from static thresholds.

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
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
