Domain Quick Reference

4.0Monitor, troubleshoot, and optimize Azure solutions

Instrument apps with Application Insights and query telemetry using KQL in Log Analytics; configure Azure Cache for Redis and Azure CDN for performance. The key is choosing the right tool: Redis for session/data caching, CDN for static content edge delivery.

Key concepts

✓Instrumenting .NET apps with Application Insights SDK, TelemetryClient, and dependency tracking
✓Writing KQL queries over Log Analytics tables like requests, traces, and exceptions
✓Configuring Azure Cache for Redis, including TTL, eviction policies, and connection resilience
✓Implementing autoscale rules, Azure CDN caching, and App Service scaling decisions

Watch out for

⚠Assuming Application Insights samples or ingests telemetry instantly, when sampling and ingestion latency can hide events during debugging.
⚠Confusing Azure Cache for Redis eviction policies or treating it as durable storage rather than an in-memory cache with data loss risk.
⚠Mixing up autoscale scale-out versus scale-up, or forgetting cooldown periods cause rules to fire slower than expected.

Exam Day Reminders

→Read every question stem fully — look for qualifiers like 'MOST likely,' 'BEST,' or 'EXCEPT.'

→Flag uncertain questions and come back — don't waste time on one question.

→Eliminate obviously wrong options first, then choose between remaining ones.

→Trust your first instinct unless you have a specific reason to change.

→For AZ-204, scenarios typically have one clearly best answer — look for the option that matches the specific constraints in the question.
