Top Study Tips
1. Master KQL First
KQL is fundamental to this exam:
- Practice writing queries daily
- Learn all major operators (where, summarize, join, extend, etc.)
- Understand time-series functions (bin, ago, between)
- Master aggregation and windowing
- Practice query optimization
2. Understand Streaming Concepts
Real-time data has unique characteristics:
- Event time vs. processing time
- Late-arriving events
- Windowing strategies (tumbling, hopping, sliding)
- Watermarking
- Exactly-once vs. at-least-once processing
3. Build End-to-End Solutions
Don't just study components:
- Ingest data via Eventstream
- Store in KQL database
- Query with KQL
- Visualize in real-time dashboard
- Set up alerts
- Monitor performance
4. Practice Time-Series Analysis
Time-series queries are heavily tested:
- Aggregating by time windows
- Calculating moving averages
- Detecting anomalies
- Comparing time periods
- Trend analysis

Key KQL Patterns to Master
Time-Series Aggregation
```kql
Events
| where timestamp > ago(1h) |
|---|
| render timechart |
```
Anomaly Detection
```kql
Metrics
| make-series Value=avg(value) default=0 on timestamp from ago(7d) to now() step 1h |
|---|
| mv-expand timestamp, Value, anomalies |
| where anomalies != 0 |
```
Moving Average
```kql
Telemetry
| order by timestamp asc |
|---|
| render timechart |
```
Session Analysis
```kql
PageViews
| order by user_id, timestamp asc |
|---|
| extend new_session = iff(time_diff > 30 or user_id != prev(user_id), 1, 0) |
| extend session_id = row_cumsum(new_session) |
```
