# Exam day playbook — SnowPro Core COF-C03

## Night before (30 minutes)

Say out loud:

1. **Three layers:** Storage · Compute (WH) · Cloud Services  
2. **Editions:** Standard (1-day TT) · Enterprise (90-day TT, MCW…) · Business Critical (security) · VPS  
3. **TT ≠ Fail-safe** · Transient has **no** Fail-safe  
4. **Masking = columns · RAP = rows**  
5. **COPY (WH) vs Snowpipe (serverless) vs Streaming (rows/SDK)**  
6. **Scale up = harder queries · Scale out = concurrency**  
7. **Share = live · Clone = zero-copy twin · Replicate = DR**

## Booking gate

- [ ] Lab 19 mock ≥ 32/40 **twice**
- [ ] `EXAM_BLUEPRINT.md` checkboxes done
- [ ] Drills from weak labs said aloud

## Pearson VUE

- Valid ID matching registration name  
- Quiet room / on-site rules followed  
- 100 questions · 115 minutes · pass **750**/1000 scaled  
- Flag hard ones; don’t bleed 5 minutes on a single stem  

## During the exam

- Prefer the **precise Snowflake term** when two answers feel right  
- “Warehouse stores data” → always false  
- Edition questions: don’t over-pick Business Critical for Time Travel alone  

## After

If you fail: 7-day wait (policy), retake fee, redo weak domains from the score report — then Lab 19 again.
