Question 1

How many distributions does an Azure Synapse Analytics dedicated SQL pool use to spread data across compute nodes?

Accepted Answer

60

Answer

Azure Synapse Analytics dedicated SQL pools always use exactly 60 distributions to enable massively parallel processing (MPP) across compute nodes.

Question 2

Which table distribution type in an Azure Synapse dedicated SQL pool is best for large fact tables that are frequently joined on a specific column?

Accepted Answer

HASH

Answer

HASH distribution places rows sharing the same hash value on the same distribution, reducing data movement during joins when the join column matches the hash key.

Question 3

Which index type in Azure Synapse dedicated SQL pools provides the best compression and performance for large-scale analytical queries?

Accepted Answer

Clustered columnstore index

Answer

Clustered columnstore indexes store data column-by-column enabling high compression ratios and efficient columnar scans that dramatically improve analytical query performance.

Question 4

What is the primary purpose of an Azure Synapse workspace?

Accepted Answer

Providing a unified collaboration environment integrating SQL, Spark, pipelines, and analytics

Answer

A Synapse workspace is a unified analytics platform that integrates dedicated SQL pools, serverless SQL, Apache Spark, Data Explorer, and pipeline authoring in a single environment.

Question 5

What is the main advantage of using REPLICATE table distribution in Azure Synapse dedicated SQL pools?

Accepted Answer

Copies the full table to each compute node, eliminating data movement during joins

Answer

REPLICATE caches a full copy of the table on each compute node so that joins with large distributed tables require no data movement across nodes.
