To answer this question, you need to understand the purpose and functionality of the Application Source Qualifier transformation in Informatica PowerCenter.

The Application Source Qualifier transformation is used to read data from various data sources and apply business rules or transformations on that data before loading it into the target. It helps in extracting, filtering, and transforming data from different types of sources.

Let's go through each option to understand why it is correct or incorrect:

Option A) COBOL Sources - This option is incorrect because the Application Source Qualifier transformation is not specifically designed for COBOL sources. However, it can be used with COBOL sources if the data can be extracted and transformed using standard connectors or plugins.

Option B) XML Sources - This option is incorrect because the Application Source Qualifier transformation is not specifically designed for XML sources. However, it can be used with XML sources if the data can be extracted and transformed using standard connectors or plugins.

Option C) Salesforce.com Sources - This option is correct because the Application Source Qualifier transformation can be used with Salesforce.com sources. It allows you to extract data from Salesforce objects and apply transformations on that data before loading it into the target.

Option D) Relational DB Sources - This option is incorrect because the Application Source Qualifier transformation is not specifically designed for relational database sources. However, it is commonly used with relational database sources to extract and transform data before loading it into the target.

The correct answer is: C) Salesforce.com Sources. This option is correct because the Application Source Qualifier transformation can be used with Salesforce.com sources to extract and transform data from Salesforce objects.

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.
