NEW QUESTION # 14
You are using the tMap component to configure a mapping.
What do the tables on the left side of the Map Editor window represent?

• A. Schemas of the input rows
• B. Expression to apply to the output data
• C. Explosions to apply to the input data
• D. Schemas of the output rows

Answer: A

Explanation:
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.

NEW QUESTION # 15
You need to create a centralized metadata connection to database server for an application.
Which steps should you take before building a Job that reads from that database?
Choose 3 answers

• A. Retrieve schemas from the database connection.
• B. Drag the Db Connection metadata into the Designer to read from the database component.
• C. Create DB Connections metadata to describe the database connection.
• D. Add a tCreatTable component to create a table in the database.
• E. Add a tMap component handle and convert DB Types.

Answer: A,B,C

Explanation:
Explanation
To create a centralized metadata connection to a database server for an application, you need to take the following steps before building a job that reads from that database:
Create DB Connections metadata to describe the database connection. You can do this by right-clicking on the DB Connections node in the Repository and selecting Create Connection. You can then enter the connection details, such as host, port, database, username, password, etc., and test the connection.
Retrieve schemas from the database connection. You can do this by expanding the DB Connections node in the Repository and right-clicking on the connection you created. You can then select Retrieve Schema and choose the tables or views you want to import as metadata schemas. You can also edit or customize the schemas as needed.
Drag the DB Connection metadata into the Designer to read from the database component. You can do this by dragging the connection or a specific schema from the Repository to the Designer workspace.
This will automatically create a database input component (such as tMysqlInput) that is configured with the connection and schema properties. You can then use this component to read data from the database in your job.
You do not need to add a tMap component to handle and convert DB Types, nor a tCreateTable component to create a table in the database. These components are not required for reading data from an existing database, but they can be used for other purposes, such as transforming or writing data.

NEW QUESTION # 18
You are collaborating on a project with other developers using talend best practices.
When should you use a tag?

• A. Capturing snapshot of a codebase that requires ongoing maintenance.
• B. Denoting a milestone in the lifecycle of a project
• C. Fixing hugs or enhancements.
• D. Denoting major or minor releases.

Answer: B

Explanation:
Explanation
Tags are used to mark specific points in the development lifecycle of a project. This can be done for a variety of reasons, such as:
To mark the completion of a major feature or release
To mark the start of a new development phase (e.g., QA, production)
To mark a known good state of the codebase (e.g., before a risky change) Tags can be used to create branches, which can then be used to develop and test new features or bug fixes.
They can also be used to deploy the codebase to different environments (e.g., development, staging, production).
Examples of when to use a tag:
When you are ready to release a new version of your application to production.
When you have completed a major feature or milestone in the development of your application.
Before making a risky change to your codebase, such as a database migration or refactoring.
When you need to deploy your application to a different environment, such as staging or production.
Benefits of using tags:
Tags can help you to keep track of the different versions of your codebase.
Tags can help you to roll back to a previous version of your codebase if necessary.
Tags can help you to deploy your codebase to different environments.
Tags can help you to collaborate with other developers more effectively.

NEW QUESTION # 19
Which statements are true about using the Implicit Context Load feature in Talend Studio?
Choose? answers

• A. Loads context parameters dynamically at the time of Job execution
• B. Loads context parameters from a delimited file only
• C. Loads context parameters from both a delimited file and a database table
• D. Loads context parameters from a database table only

Answer: A,C

Explanation:
Explanation
The Implicit Context Load feature in Talend Studio is a way of loading context parameters dynamically at the time of job execution from an external source, such as a delimited file or a database table. This feature can be enabled by checking the Implicit Context Load option in the Advanced Settings tab of Run Job section in Talend Studio. This feature allows the developer to avoid hard-coding context parameters in the job design and to change them easily without modifying the job. The Implicit Context Load feature can load context parameters from both a delimited file and a database table, depending on the configuration of the Implicit Context Load option. The developer can specify the file path or the database connection details, as well as the mapping between the source columns and the context variables.

NEW QUESTION # 20
Which statement is true about the Sync columns button on the Basic settings tab of the Component view?
Choose 2 answers

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

Answer: B,C

Explanation:
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.

NEW QUESTION # 21
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?

• A. Int nb_line-(String)globalMap.put(''tFileInputDelimited_1_NB_LINE'')
• B. Int nb.line-(integer)globalMap.put(''tFileInputDelimited_1_NB_LINE'')
• C. Int nb_line=(integer)globalMap.put(''tFileInputDelimited_1_NB_LINE'')
• D. Int nb_line-(integer)globalMap.put(''tFileInputDelimited_1_NB_LINE'')

Answer: B

Explanation:
Explanation
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.

NEW QUESTION # 22
Which methods car you use to specify the schema in a tFilelnputDelimited component?
Choose 3 answers

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

Answer: A,B,D

Explanation:
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.

NEW QUESTION # 23
Which statements are true about configuring the input sources of a tMap component?
Choose answers

• A. Thy main input source is always placed on topand cannot be moved within the tMap component.
• B. You can use the up and down arrows to interchange the order of the Lookup tables.
• C. The order in which the input sources appear on the map does not matter, provided the joins are configured correctly.
• D. The main input source will always be placed on top by default hut ran be dragged to any position.

Answer: A,B

Explanation:
Explanation
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.

NEW QUESTION # 24
You have two branches: Branch1 contains Job1, and Branch 2 contains Job 2. You want to copy Job1 to Branch 2 and preserve the change history when connecting Studio to Talend Administrator Center.
Which method should you use to preserve the change history?

• A. Switch to Branch 1, right-click Job 1, select Copy to branch, and select Branch 2.
• B. Switch to branch 1, copy the Branch 1 Job, switch to Branch 2, and paste the Job into Branch 2.
• C. Switch to Branch1, copy lob 1, switch to Branch 2, and paste Job 1 over Job 2.
• D. Switch to Branch 1, copy the Branch 1 job, switch to Branch 2, and paste the job into Branch 2.

Answer: A

Explanation:
Explanation
To copy Job1 from Branch1 to Branch2 and preserve the change history when connecting Studio to Talend Administration Center, you need to use the Copy to branchoption. This option allows you to copy a job or a folder from one branch to another branch in the same project without losing the version history. You can access this option by switching to Branch1, right-clicking on Job1 in the Repository tree view, and selecting Copy to branch. This will open a dialog box where you can select Branch2 as the target branch and confirm the copy operation.
You do not need to use the import items, create standard job, or paste over options. These options are not used to copy jobs between branches and preserve the change history. The import items option is used to import items (such as jobs, metadata, routines, etc.) from an archive file that can be exported from another project or workspace. The create standard job option is used to create a new job with a name and a description. The paste over option is used to overwrite an existing job with another job that has been copied or cut from the same or another project. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Copy to branch - 7.3]

NEW QUESTION # 25
Where can you specify the remote JobServer to execute a Job?

• A. Extra tab in the Job view
• B. Target Exec tab in the Run view
• C. Run/Debug section in the Preference window
• D. Job settings section of the Project Settings windows

Answer: B

Explanation:
Explanation
To specify the remote JobServer to execute a job, you need to use the Target Exec tab in the Run view of Talend Studio. The Run view allows you to configure and execute your job from Talend Studio. The Target Exec tab allows you to select whether you want to run your job locally or remotely on a JobServer. A JobServer is a server application that allows you to execute jobs remotely from Talend Studio or Talend Administration Center. To run your job on a remote JobServer, you need to select Remote Jobserver option from the drop-down menu and select or add a JobServer connection from the list.
You do not need to use Job settings section of Project Settings window, Extra tab in Job view, or Run/Debug section in Preferences window. These windows are not used to specify remote JobServer execution. The Job settings section of Project Settings window is used to configure general settings for your jobs, such as versioning, statistics, logs, etc. The Extra tab in Job view is used to configure extra features for your job, such as implicit context load, tStatCatcher, tLogCatcher, etc. The Run/Debug section in Preferences window is used to configure run/debug settings for your Talend Studio, such as JVM arguments, execution mode, etc. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Run view - 7.3],

NEW QUESTION # 26
You are building a complex Job and want to explore different optionsfor optimizing execution timesusing parallelism.
How can you identify execution times to verify the effectiveness of your changes?
Choose 2 answers

• A. Comparing time stamp in Trace Debug mode.
• B. Observing the execution time in the Code view.
• C. Observing the execution times that annotate the flows in the Designer.
• D. Heading the time stamps from the execution console in the Run view.

Answer: C,D

Explanation:
Explanation
To identify execution times to verify the effectiveness of your changes, you can use one of these methods:
Reading the time stamps from the execution console in the Run view. This method allows you to see the start and end time of each subjob and component in your job, as well as the total execution time of the job. You can also see the number of rows processed by each component and the status of the job (success or failure).
Observing the execution times that annotate the flows in the Designer. This method allows you to see the execution time of each flow (main, lookup, reject, etc.) between components in your job. You can also see the number of rows processed by each flow and the throughput (rows per second) of each flow.
You cannot use these methods to identify execution times:
Observing the execution time in the Code view. This method does not show you the execution time of your job or its components, but only the generated code of your job in Java or Perl. The Code view is useful for debugging or customizing your code, but not for measuring performance.
Comparing time stamps in Trace Debug mode. This method does not show you the execution time of your job or its components, but only the values of eachcolumn for each row processed by your job. The Trace Debug mode is useful for tracing data quality or transformation issues, but not for measuring performance.

NEW QUESTION # 27
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

• A. Header
• B. Field separator
• C. Footer
• D. Limit
• E. Schema

Answer: A,B,E

Explanation:
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.

NEW QUESTION # 28
You are building a Job that consists of two subJobs being sequentially executedI he first subJob completes successfully.
Which component in the first subJob triggers the execution of the second subJob?

• A. Input component
• B. Any component
• C. Final component
• D. Start component

Answer: D

Explanation:
Explanation
The Start component in a subjob triggers the execution of the next subjob in a sequential order. The Start component is used to define where a subjob begins and to link it with other subjobs within a job. The Start component has only one output link that can be connected to any other component in the same subjob or to another Start component in another subjob. When a subjob completes successfully, it sends an OnSubjobOk trigger to its Start component, which then activates the next subjob linked to it. The Final component, on the other hand, is used to define where a subjob ends and to perform some actions after its completion, such as sending anemail or logging a message. The Final component has no output link and does not trigger any other subjob. The Input component and any other component in a subjob do not trigger any other subjob by themselves, unless they are connected to a Start component through an output link or an OnComponentOk trigger.
