The correct combination is Azure Monitor Metrics and Azure Monitor Logs. Azure Monitor Metrics is the right choice for real-time querying of custom metrics from AKS because it stores numeric time-series data with sub-minute granularity, enabling near-instant dashboard updates and alerts through Azure Dashboards or Grafana. Azure Monitor Logs, powered by Log Analytics, handles the one-year retention requirement by offering configurable retention up to 730 days and supports KQL queries for compliance audits. On the AZ-305 exam, this scenario tests your understanding of the separation between time-series metrics for operational speed and log-based data for long-term storage. A common trap is choosing Azure Monitor Metrics for logs or assuming Application Insights handles both, but Metrics lacks log retention and Logs lacks sub-minute granularity. Memory tip: think “Metrics for speed, Logs for need”—real-time dashboards need Metrics, compliance archives need Logs.
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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
You are designing a monitoring solution for a critical application running on Azure Kubernetes Service (AKS). The application generates custom metrics that need to be queried in real-time for dashboards. You also need to retain logs for one year for compliance. Which combination of services should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Monitor Metrics and Azure Monitor Logs
Azure Monitor Metrics is the correct choice for real-time querying of custom metrics because it stores numeric time-series data with sub-minute granularity and supports near real-time alerting and dashboarding via Azure Dashboards or Grafana. Azure Monitor Logs (Log Analytics) is required for retaining logs for one year, as it offers configurable retention up to 730 days (2 years) and supports KQL queries for compliance and audit needs. Together, they provide a unified monitoring solution for AKS that meets both real-time metric querying and long-term log retention requirements.
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.
✓
Azure Monitor Metrics and Azure Monitor Logs
Why this is correct
Metrics for real-time dashboards, Logs for long-term log retention and querying.
Related concept
Read the scenario before looking for a memorised answer.
✗
Prometheus and Azure Monitor Logs
Why it's wrong here
Prometheus is a metrics solution, but Azure Monitor already provides Metrics; Logs would be needed for log retention.
✗
Azure Data Explorer and Azure Blob Storage
Why it's wrong here
Data Explorer is not the primary monitoring tool for AKS; Blob Storage alone doesn't support real-time querying.
✗
Application Insights and Azure Storage
Why it's wrong here
Application Insights is for app telemetry, not infrastructure metrics; Storage is for archival, not real-time querying.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Prometheus as the only way to collect custom metrics in AKS, but Azure Monitor Metrics natively supports custom metrics via the Azure Monitor agent and does not require a separate Prometheus deployment for real-time dashboards.
Detailed technical explanation
How to think about this question
Azure Monitor Metrics uses a time-series database that stores metrics for up to 93 days by default, but you can extend retention by routing to Log Analytics, which uses Kusto Query Language (KQL) for complex queries. For AKS, custom metrics can be collected via the Metrics API or the Container Insights agent, which sends both metrics and logs to the same Log Analytics workspace, enabling correlation between real-time performance and historical log data. In a real-world scenario, you might use Azure Monitor Metrics for live dashboards showing CPU/memory of pods, while Azure Monitor Logs retains container stdout/stderr logs for one year to meet compliance audits.

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.
