Exam: dp-203
Domain: Monitor and optimize data storage and data processing
Topic: Monitor data storage and data processing
Difficulty: medium
You are managing a large-scale ETL process in Azure Synapse Analytics and want to optimize the performance of your queries. You notice that one of the queries is taking longer than expected and suspect that the query execution plan might be suboptimal. What tool or feature in Azure Synapse Analytics would you use to analyze and optimize the query execution plan?
Answer Options
A
Use Azure Data Factory to schedule and manage data integration tasks.
B
Enable the Query Store in Azure Synapse Analytics to analyze query execution plans.
C
Implement Azure SQL Database Transparent Data Encryption to secure the data.
D
Deploy Azure Machine Learning to predict future query performance.
Correct Answer
B: Enable the Query Store in Azure Synapse Analytics to analyze query execution plans.
Explanation
The correct answer is B. You should use the Query Store in Azure Synapse Analytics to analyze and optimize the query execution plans. The Query Store provides detailed information about query performance and execution plans, allowing you to identify and optimize inefficient queries. Option A is incorrect because it refers to Azure Data Factory, which is used for data integration and not for query optimization. Option C is incorrect as it pertains to Azure SQL Database, which is a different service with its own query optimization tools. Option D is incorrect as it refers to Azure Machine Learning, which is used for predictive analytics and not for query execution plan analysis.
