You need to calculate the total number of rows in an input file using a tMlelnputDelimited component.Which code should you use in a tJava component to write a nb-line variable?
Answer(s): C
You need to use the following code in a tJava component to write a nb_line variable:int nb_line = (Integer)globalMap.get("tFileInputDelimited_1_NB_LINE"); This code retrieves the value of the global variable tFileInputDelimited_1_NB_LINE, which stores the number of rows processed by the tFileInputDelimited component, and assigns it to an integer variable named nb_line. You can then use this variable to print or manipulate the number of rows in your Job. Note that you need to use globalMap.get, not globalMap.put, to access the value of a global variable.
Which parameters are defined in File Delimited metadata? Choose? answers
Answer(s): B,C
The parameters that are defined in File Delimited metadata are:Row separator: This parameter defines the character or string that separates each row of data in a delimited file. For example, a row separator can be a newline character (\n), a carriage return (\r), or a combination of both (\r\n).File path: This parameter defines the location and name of the delimited file that you want to read or write. You can browse your local system or enter a URL to specify the file path. You can also use context variables or global variables to make the file path dynamic.
You built multiple Jobs in Studio, each uses its own tDBInput component to connect to a common database server, but they all use different credentials.How should you configure the tDBInput components?
Answer(s): B
The tDBInput component allows you to configure the connection properties either by using a built-in mode or by using a repository mode. The built-in mode lets you set all the relevant properties manually, such as host, port, database, username, password, etc. The repository mode lets you reuse an existing connection metadata that is stored in the repository. If you have multiple jobs that use different credentials to connect to a common database server, you should use the built-in mode and set the properties for each job individually. This way, you can avoid creating multiple connection metadata in the repository and maintain them separately.

You have a tMap component whose main input provides the following data:There is also a lookup table with the following data:An inner join is configured between the State column of the main input with the State Code column of the lookup table.What happens when the row containing the name Andrew laylor is processed?
Answer(s): D
The tMap component allows you to perform data transformations and joins between multiple input sources and output targets. You can configure different types of joins between the main input and the lookup tables, such as inner join, left outer join, right outer join, etc. An inner join returns only the matching rows from both tables based on a join condition. If a row from the main input does not match any row from the lookup table, it is considered as an inner join reject. You can configure an output to collect these rejects by setting the Catch inner join reject option to true. If you do so, the data will flow only to that output and not to the main output. If you do not configure an output to collect the rejects, the data will be ignored and no error will be raised.

Which statements are true about configuring the input sources of a tMap component? Choose answers
Answer(s): A,B
The tMap component allows you to configure multiple input sources for your data transformation and mapping. The main input source is always placed on top of the tMap component and cannot be moved within it. The main input source provides the data flow that drives the processing of the tMap component. The lookup tables are placed below the main input source and can be reordered by using the up and down arrows on the toolbar. The order in which the lookup tables appear on the tMap component does not affect the functionality of the joins, as long as they are configured correctly with the appropriate join conditions and expressions.
