Q 1. A Mapping is developed to extract data from XML file and using normalizer transformation normalization is done and loaded into a database table. In a particular project, this logic is used by many applications so for reusability, this logic is decided to incorporate in a mapplet. By this way, all applications can use this single mapplet while developent.
Which of the below statement is true regarding this design?

Note: There can be multiple correct answers to this question.

Q 2. A Mapping will extract data from staging table and based on some conditions it is routed to 3 different target tables. Router transformation is used to achieve this. A temporary audit table is populated after the completion of each run. So we need to delete that temporary audit table, before reading data from the staging table.
How can this be achieved?

Note: There can be multiple correct answers to this question.

Q 3. Source qualifier transformation can be used to join data from multiple sources. But a mapping is developed with joiner transformation to join source data. What can be the reasons to do so?

Note: There can be multiple correct answers to this question.
