Question 218 of 760
DP-203 Develop data processing Practice Question
You are designing a data processing solution in Azure Synapse Analytics. You need to load data from multiple sources into a dedicated SQL pool. Which THREE of the following are best practices for loading data?
⚠ Common exam trap
Many candidates assume more files always increase parallelism, but Azure Synapse Analytics optimizes for fewer, larger files to minimize metadata operations and maximize throughput.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use round-robin distribution for staging tables
Round-robin distribution is recommended for staging tables because it distributes data evenly across all distributions without requiring a hash key, minimizing data movement during the load process. Since staging tables are temporary and used for intermediate storage, the even distribution ensures that the subsequent INSERT...SELECT operation into the final table benefits from maximum parallelism and reduced skew.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use round-robin distribution for staging tables
Why this is correct
Round-robin distributes data evenly for fast load.
- ✓
Use a staging table to load data and then insert into the final table
Why this is correct
Staging reduces locking and allows data validation.
- ✗
Split data into many small files to increase parallelism
Why it's wrong here
Many small files cause overhead; use fewer, larger files.
- ✓
Use PolyBase or COPY statement for parallel loading
Why this is correct
Parallel loading maximizes throughput.
- ✗
Enable clustered columnstore index during load to improve query performance
Why it's wrong here
Disable indexes during load for faster inserts.
