While it can perform large-scale data processing and integrates with Apache Spark, Synapse is more focused on data warehousing, ETL (extract, transform, load) processes, and business intelligence rather than being a dedicated platform for Spark-based data processing like Databricks.
D) Azure Cosmos DB is a globally distributed NoSQL database service designed for fast, scalable, and low-latency data access. While it is a powerful database solution, it is not specifically tailored for big data processing or distributed data analytics using Apache Spark.
Question 80:
Which of the following Azure services can be used to analyze and visualize data stored in Azure Data Lake and other big data sources in real time?
A) Azure Power BI
B) Azure Synapse Analytics
C) Azure Stream Analytics
D) Azure Data Factory
Answer: C) Azure Stream Analytics
Explanation:
C) Azure Stream Analytics is the correct answer. Azure Stream Analytics is a fully managed real-time analytics service that enables users to analyze and visualize streaming data from various sources, such as IoT devices, sensors, or event streams. It can process large amounts of data in real time, applying transformations and running analytics queries to derive insights as data flows into the system. Stream Analytics integrates seamlessly with Azure Data Lake, Azure Blob Storage, and other Azure data services, making it ideal for scenarios where data needs to be processed and analyzed in real time.
The service supports various data inputs, including real-time event streams from devices or applications, and outputs the processed data to a variety of destinations, such as Power BI for visualization, Azure SQL Database for further analysis, or even Azure Data Lake for long-term storage.
A) Azure Power BI is a data visualization and business intelligence tool that allows users to create reports and dashboards based on data stored in various sources, including Azure Data Lake. However, Power BI is not designed for real-time data processing like Stream Analytics, which is more suited for streaming and analyzing data as it arrives.
B) Azure Synapse Analytics is a comprehensive analytics service that integrates big data and data warehousing. While it supports data exploration and analysis, it is more focused on large-scale batch processing rather than real-time data streaming.
D) Azure Data Factory is a data integration service that facilitates ETL (extract, transform, load) processes for moving and transforming data across different sources. While Data Factory is excellent for batch data movement and transformation, it does not provide real-time analytics and visualization like Stream Analytics.
