To answer this question, you need to understand the Microsoft SQL BI tool and its components.
Option A) SSAS - This option is correct because SSAS (SQL Server Analysis Services) is the service/server in the Microsoft SQL BI tool that supports the creation and design of OLAP (Online Analytical Processing) databases. SSAS provides tools for creating multidimensional and tabular models that can be used for data analysis and reporting.
Option B) SSIS - This option is incorrect because SSIS (SQL Server Integration Services) is a service/server in the Microsoft SQL BI tool that is used for data integration and ETL (Extract, Transform, Load) processes. While SSIS can be used to extract data from various sources and load it into an OLAP database, it is not specifically designed for the creation and design of OLAP databases.
Option C) SSRS - This option is incorrect because SSRS (SQL Server Reporting Services) is a service/server in the Microsoft SQL BI tool that is used for creating and managing reports. SSRS is not specifically designed for the creation and design of OLAP databases.
Option D) SQL RDBMS - This option is incorrect because SQL RDBMS (Relational Database Management System) refers to the underlying database engine that powers the Microsoft SQL BI tool. While SQL RDBMS is used for storing and managing relational data, it is not specifically designed for the creation and design of OLAP databases.
The correct answer is A) SSAS. This option is correct because SSAS is the service/server in the Microsoft SQL BI tool that supports the creation and design of OLAP databases.
