What you get
Papers are cut from the bank and weighted like the real exam, and no question appears in two of them. Every wrong answer comes back on later days until you have it right.
What the exam covers
| The Databricks Lakehouse Platform and Delta Lake | Not published |
| Building pipelines, production and governance | Not published |
Two sample questions
1. Which risk accompanies using spot instances for workers?
- Cost increases
- Jobs run faster always
- No risk arises
- Workers may be reclaimed, causing task retries or job failure — correct
Why: Spot capacity can be reclaimed by the provider, so tasks must be retried and long jobs may fail.
2. Which technique addresses skew on a join key?
- Increasing the cluster only
- Salting the key or letting adaptive execution split the skewed partition — correct
- Removing the join
- Disabling statistics
Why: Salting spreads a hot key across partitions, and adaptive execution can split skewed partitions automatically.
