QUESTION: 6

Which statement is true about the Sync columns button on the Basic settings tab of the Component view? Choose 2 answers

Retrieves and synchronizes the output file schema with the input file schema for tFileOutputed limited.
Retrieves the schema of the current component to match the Next component
Retrieves the schema from the input component connected in the lob.
Retrieves and synchronizes the output schema with the input schema for tJavaRow.

Answer(s): C,D

Explanation:

The Sync columns button on the Basic settings tab of the Component view retrieves the schema from the input component connected in the Job and synchronizes it with the current component's schema. This button is available for most of the components that have an input and an output schema, such as tJavaRow, tMap, tFileOutputDelimited, etc. However, this button does not retrieve and synchronize the output file schema with the input file schema for tFileOutputDelimited, as this component only has one output schema.

QUESTION: 7

In some instances, after applying changes to a component schema, you are asked if you would like to propagate the changes.
What is the significance of this prompt?

Confirm Out you want to apply the schema, changes to the previous component in the Job.
Confirm That you want to apply the schema changes to the selected component.
Confirm that you want to apply the schema changes to both the previous and next components in the Job.
Confirm that you want to apply the schema changes to the next component in the Job.

Answer(s): D

Explanation:

In some instances, after applying changes to a component schema, you are asked if you would like to propagate the changes. This prompt is significant because it allows you to confirm that you want to apply the schema changes to the next component in the Job. This can save you time and effort by automatically updating the schema of the downstream component, instead of manually editing it. However, you should be careful when propagating changes, as it may overwrite existing schemas or cause errors in the Job logic. You can also choose to cancel the propagation and edit the schema manually.

QUESTION: 8

Using the following input file format as an example:

Which tFileinputDelimted component parameters should you configure to parse the input file correctly? Choose 3 answers

Limit
Schema
Field separator
Footer
Header

Answer(s): B,C,E

Explanation:

Using the following input file format as an example:
<OCR>Name, Phone Abraham Smith, 510-555-5555 ... Steven Doe, 613-555-5555 </OCR> The tFileInputDelimited component parameters that you should configure to parse the input file correctly are Schema, Field separator, and Header. The Schema parameter defines the structure and type of the data in the input file. You can use a built-in schema or a repository schema to specify the columns and their properties. The Field separator parameter defines the character that separates each field in a row of data. In this case, it is a comma (,). The Header parameter defines the number of rows to be skipped at the beginning of the file. In this case, it is 1, as the first row contains the column names.

QUESTION: 9

Which methods car you use to specify the schema in a tFilelnputDelimited component? Choose 3 answers

Drag a generic schema metadata item onto the Designer.
Add the component then drag and drop a generic schema metadata item onto the component.
Add the schema to the component using the Schema Editor
Drag a File delimited metadata item from the Repository onto the design workspace.
Add the component, open the Component view, select the Built-in schema type, then click the Edit schema button.

Answer(s): B,D,E

Explanation:

The methods that you can use to specify the schema in a tFileInputDelimited component are:
Add the component then drag and drop a generic schema metadata item onto the component. This method allows you to reuse an existing schema that is stored in the Metadata section of the Repository. A generic schema is a schema that is not associated with any specific file format or connection type. You can create a generic schema by right-clicking on Generic Schema in the Repository and selecting Create Generic Schema.
Drag a File delimited metadata item from the Repository onto the design workspace. This method allows you to create a new tFileInputDelimited component with a predefined schema that is based on a specific delimited file. A File delimited metadata item is a metadata item that contains information about a delimited file, such as its path, format, encoding, field separator, etc. You can create a File delimited metadata item by right-clicking on File delimited in the Repository and selecting Create File delimited.
Add the component, open the Component view, select the Built-in schema type, then click the Edit schema button. This method allows you to create a custom schema for the tFileInputDelimited component within the Component view. A built-in schema is a schema that is defined locally for a specific component and cannot be reused by other components. You can edit a built-in schema by clicking on the Edit schema button in the Basic settings tab of the Component view.

QUESTION: 10

You are using the tMap component to configure a mapping.
What do the tables on the left side of the Map Editor window represent?

Explosions to apply to the input data
Schemas of the output rows
Schemas of the input rows
Expression to apply to the output data

Answer(s): C

Explanation:

The tables on the left side of the Map Editor window represent the schemas of the input rows. The schemas define the structure and type of the data that is coming from the input components connected to the tMap component. You can drag and drop columns from the input tables to the output tables on the right side of the Map Editor window to create mappings and transformations.
