NEW QUESTION # 13
What determines the name of the tMap output row that delivers join rejects?
- A. The name is configurable in the Component view of the tMapcomponent
- B. The name is determined by the output table you create to catch the rejects.
- C. The name is determined by the input table, you create to generate the rejects.
- D. The name is predetermined; it is always named Innerjoin Reject.
Answer: B
Explanation:
Explanation
The tMap component allows you to 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. The name of the output row that delivers the join rejects is determined by the output table you create to catch the rejects. You can name the output table as you wish, such as Rejects, Errors, etc. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend,
NEW QUESTION # 14
Where can you simultaneously define primary keys for the Update and Delete operations in a tMysqlOutput component?
- A. Advanced settings view, select the Additional columns options check box
- B. Advanced settings view, select the Use hint options check box
- C. Basic settings view, select the Use field options check box
- D. Advanced settings view, select the Use field options check box
Answer: D
Explanation:
Explanation
The tMysqlOutput component is used to write data into a MySQL database table. The Update and Delete operations are used to modify or remove existing rows in the table based on a primary key. To define the primary key for these operations, you need to use the Use field options check box in the Advanced settings view of the component. This will enable you to specify which columns are used as keys for each operation.
You can also define other options for each column, such as nullable, length, precision, etc. The Use field options check box is not available in the Basic settings view of the component. The Additional columns options check box and the Use hint options check box are used for other purposes, such as adding extra columns or hints to the SQL query, and they do not affect the primary key definition.

NEW QUESTION # 15
A colleague has exported a Data Integration Job to run outside Talend Studio.
How do you run the Job?
- A. Install the Job and start the resulting service.
- B. Extract the contents of the archive and run the batch file and shell script.
- C. Extract the content of the archive and run the batch file or the shell script.
- D. Extract the files from the archive and run the JAR file.
Answer: C
Explanation:
Explanation
To run a job that has been exported by a colleague to run outside Talend Studio, you need to extract the content of the archive and run the batch file or the shell script. The archive file contains all the files and libraries required to run the job independently from Talend Studio on any platform that supports Java. The archive file also contains two executable files: a batch file (.bat) for Windows platforms and a shell script (.sh) for Linux platforms. You need to run the appropriate file for your platform by double-clicking on it or using a command line tool. This will launch the job and display its output in a console window.
You do not need to extract the contents of the archive and run both the batch file and shell script, install the job and start the resulting service, or extract the files from the archive and run the JAR file. These methods are not correct or available in Talend Studio and may cause errors or unexpected results.

NEW QUESTION # 16
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 Branch1, copy lob 1, switch to Branch 2, and paste Job 1 over Job 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 Branch 1, right-click Job 1, select Copy to branch, and select Branch 2.
- D. Switch to branch 1, copy the Branch 1 Job, switch to Branch 2, and paste the Job into Branch 2.
Answer: C
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.

NEW QUESTION # 17
You need to set up a server in your Talend environment that enables several members of your team to collaborate on a project.
Which application must you enable before working on a remote project?
- A. Talent Administration Center instance must be running with the team members and project configured.
- B. Git or SVN server instance must be running.
- C. Git or SVN client must be installed on each developed workstation.
- D. Talend admission Center service must be running on each development workstation.
Answer: A,B
Explanation:
Explanation
To set up a server in your Talend environment that enables several members of your team to collaborate on a project, you need to enable two applications before working on a remote project: Git or SVN server instance and Talend Administration Center instance. These applications are used to manage version control and collaboration for your project.
Git or SVN server instance is a server application that allows you to store and track changes of your project files using a version control system. Git and SVN are two popular version control systems that are supported by Talend Studio. You need to have a Git or SVN server instance running and accessible by your team members before working on a remote project. You also need to have a Git or SVN client installed on each development workstation to connect to the server and perform version control operations.
Talend Administration Center is a web-based application that allows you to manage users, projects, tasks, execution servers, and licenses for your Talend environment. You need to have a Talend Administration Center instance running and accessible by your team members before working on a remote project. You also need to configure the team members and project settings in Talend Administration Center to grant access and permissions for your project.

NEW QUESTION # 18
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 database table only
- C. Loads context parameters from both a delimited file and a database table
- D. Loads context parameters from a delimited file 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 # 19
You create a Job consisting of two subJobs, A and B. You added Joblet C with the intension of running it between A and B.
What are the minimum requirements to orchestrate this?(Choose Two)
- A. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into B.
- B. Link A, B and C using On Subject Ok triggers.
- C. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into C
- D. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into A.
Answer: B,C
Explanation:
Explanation
To create a job consisting of two subjobs, A and B, and add a Joblet C with the intention of running it between A and B, you need to do the following steps:
Design subjob A by adding components and links to it in the Designer workspace.
Add a Start component to mark the beginning of subjob B and link it to subjob A using an OnSubjobOk trigger.
Design subjob B by adding components and links to it after the Start component in the Designer workspace.
Add a tJobletTriggerInput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.
Add a tJobletTriggerOutput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.
Drag your Joblet C from the Repository tree view to the Designer workspace between subjob A and subjob B.
Link your Joblet C to subjob A using an OnComponentOk trigger from the last component of subjob A to the tJobletTriggerInput component of your Joblet C.
Link your Joblet C to subjob B using an OnComponentOk trigger from the tJobletTriggerOutput component of your Joblet C to the Start component of subjob B.
The minimum requirements to orchestrate this are adding TRIGGER_INPUT and TRIGGER_OUTPUT components into C and linking A, B, and C using OnSubjobOk triggers. These are generic components that allow you to define triggers for your Joblet without depending on specific components. You do not need to add TRIGGER_INPUT and TRIGGER_OUTPUT components into A or B, as these are regular subjobs that can use any type of components or triggers.

NEW QUESTION # 20
Which exceptions car be caught using tLogCatcher?
Choose 3 answers
- A. tDie
- B. tAssertCatcher
- C. tWarn
- D. OnbubjobError Exception
- E. Java Exception
Answer: A,C,E
Explanation:
Explanation
The tLogCatcher component can catch exceptions from three types of components: tWarn, tDie, and Java Exception. The tWarn component is used to trigger a warning message that can be caught by the tLogCatcher component for an exhaustive log. The tDie component is used to stop the execution of a job or a subjob and return an error code that can be caught by the tLogCatcher component for an exhaustive log. The Java Exception component is used to handle any Java exception that occurs during the execution of a job or a subjob and pass it to the tLogCatcher component for an exhaustive log. The tLogCatcher component cannot catch exceptions from other types of components, such as OnSubjobError Exception or tAssertCatcher. The OnSubjobError Exception is a trigger that is activated when an error occurs in a subjob and can be used to perform some actions after the error, such as sending an email or logging a message. The tAssertCatcher component is a component that collects the assert data generated by the tAssert component and passes it on to the output defined. The tAssert component is used to verify if a condition is true or false and generate an assert data accordingly. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend,

NEW QUESTION # 21
In Talend Studio, you have access to a references project named project_ref. You need to reuse a Job named testJob from the project_ref in your main Job.
- A. Navigate to @ Referenced project, @ project_ref, Job Designs, Standard, then select testJob.
- B. Right-click Job Designs and click import items.
- C. Right-click Job Designs, click Crete Standard Job, and enter testJob as the Job name.
- D. Navigate to Metadata, @ project ref, Job Designs, Standard, then select testJob.
Answer: A
Explanation:
Explanation
To reuse a job named testJob from a referenced project named project_ref in your main job, you need to navigate to @Referenced project, @project_ref, Job Designs, Standard, then select testJob. A referenced project is a project that can be accessed from another project in read-only mode. You can add a referenced project to your main project by using the Project Settings window in Talend Studio. You can then browse the items (such as jobs, metadata, routines, etc.) of the referenced project in the Repository tree view under the
@Referenced project node. You can drag and drop any item from the referenced project to your main job design workspace.
You do not need to use import items, create standard job, or navigate to Metadata options. These options are not used to reuse jobs from referenced projects. 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 Metadata node in the Repository tree view is used to store and manage metadata definitions for various data sources (such as databases, files, web services, etc.).

NEW QUESTION # 22
Which factors can affect the context in which a Job is run?
Choose 2 answers
- A. Context chosen by the developer when running the Job. Context available in the Basic Run tab of Run Job section.
- B. tContextDump component ran change the context name in the course of the lob execution.
- C. tRunJob component can influence the context in which the child Job runs.
- D. tContextLoad component can change the context name in the course of the Job execution.
Answer: A,C
Explanation:
Explanation
The context in which a job is run can be affected by different factors, such as the context chosen by the developer when running the job, or the tRunJob component that can influence the context in which the child job runs. The context chosen by the developer when running the job can be selected from the Basic Run tab of Run Job section in Talend Studio. This allows the developer to test the job with different sets of context variables without modifying the job design. The tRunJob component can be used to call another job as a subjob within a parent job. The tRunJob component can pass the context parameters from the parent job to the child job, or use a specific context for the child job. This allows the developer to reuse existing jobs and control their execution contexts. The tContextLoad component and the tContextDump component do not affect the context name in which a job is run, but they can affect the context values. The tContextLoad component can load context parameters from a file or a database table at runtime and overwrite the existing values. The tContextDump component can display or save the current context parameters and their values for debugging purposes.

NEW QUESTION # 23
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?
- A. Confirm That you want to apply the schema changes to the selected component.
- B. Confirm that you want to apply the schema changes to both the previous and next components in the Job.
- C. Confirm that you want to apply the schema changes to the next component in the Job.
- D. Confirm Out you want to apply the schema, changes to the previous component in the Job.
Answer: C
Explanation:
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.
NEW QUESTION # 24

- D. Type the Joblet name on the Studio canvas, then select if from the Palette drop-down menu.
- E. Use a tRunJob component and select the Joblet from the drop-down menu.
Answer: B,C,D
Explanation:
Explanation
To add a Joblet to your Talend Job, you can use one of these options:
Type the Joblet name on the Studio canvas, then select it from the Palette drop-down menu. This will create a Joblet container on your canvas that contains all the components and links of your Joblet.
Drag the Joblet from Repository tree view to designer canvas. This will also create a Joblet container on your canvas that contains all components and links of your Joblet.
Drag Joblet from Palette to design workspace. This will open a dialog box where you can select an existing Joblet from Repository or create a new one.
You cannot use a tRunJob component and select Joblet from drop-down menu, nor right-click Joblet from Palette and select Add option. These methods are not available in Talend Studio and may cause errors or unexpected results. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend,

NEW QUESTION # 25
How are contexts defined?
- A. They are automatically defined by the types of components used in the Job.
- B. Talend Studio defines a default context, and you can define more as needed.
- C. In addition to a default context, Talend Studio defines a list of standard contexts you can use in your Ions.
- D. You must define the contexts
Answer: D
Explanation:
Explanation
Contexts are a way of defining different sets of values for variables that are used in a job. For example, you can define a context for testing and another context for production, with different values for the database connection parameters, file paths, etc. You can then switch between the contexts easily without modifying the job design. Contexts are not automatically defined by the types of components used in the job, nor by Talend Studio. You must define the contexts yourself in the Contexts tab of your job. You can also create context groups in the Repository and reuse them in multiple jobs. References: Talend Data Integration - Software to Connect, Access, and Transform Data | Talend,
NEW QUESTION # 26
Which method allows you to execute the compiled Job Talend Studio?
- A. Click the Export button in the Edit Properties window.
- B. Select Save As on the main File menu
- C. Right-click the Job in the Repository and select Build Job
- D. Right-click the Job in the Repository and select Export items.
Answer: C
Explanation:
Explanation
To execute the compiled job outside Talend Studio, you need to right-click on the job in the Repository tree view and select Build Job option. This option allows you to export your job as an executable file that can be run independently from Talend Studio on any platform that supports Java. You can access this option by right-clicking on your job in the Repository tree view and selecting Build Job. This will open a dialog box where you can configure the build settings, such as destination folder, archive name, context, etc.
You do not need to click the Export button in the Edit Properties window, right-click on the job in the Repository and select Export items, or select Save As on the main File menu. These options are not used to execute the compiled job outside Talend Studio. The Export button in the Edit Properties window is used to export your job properties as an XML file. The Export items option is used to export your items (such as jobs, metadata, routines, etc.) as an archive file that can be imported into another project or workspace. The Save As option is used to save a copy of your job with a different name or location. References: Talend Open Studio:

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. Footer
- B. Limit
- C. Field separator
- D. Header
- E. Schema
Answer: C,D,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 designing a Job that can run in two contexts, Test and Production. You want to run it as a standalone job outside Talend Studio.
How do you accomplish this?
- A. Set the desired context as the default, then build the Job. Rebuild the Job if you need to run it in a different context.
- B. Build the Job with the desired context selected in the Build Job windows. Build a separate copy if you need to run the Job in a different context.
- C. Build the Job with the Context scripts option selected in the Build Job windows. You will be prompted for the context.
- D. Build the Job with the Context scripts option selected in the Build Job windows. Before running the Job, edit the script according to the context in which want to run the job.
Answer: B
Explanation:
Explanation
To design a job that can run in two contexts, Test and Production, and run it as a standalone job outside Talend Studio, you need to do the following steps:
Define the context variables and values for each context in the Contexts tab of your job. A context variable is a variable that can store a value that can be changed at runtime or between different contexts.
You can use context variables to parameterize the properties or expressions of your job components.
Build the job with the desired context selected in the Build Job window. You can access this option by right-clicking on your job in the Repository tree view and selecting Build Job. This will open a dialog box where you can configure the build settings, such as destination folder, archive name, context, etc.
You need to select the context that you want to use for your job execution from the drop-down menu.
Extract the content of the archive file that contains your job executable files and libraries. The archive file also contains two executable files: a batch file (.bat) for Windows platforms and a shell script (.sh) for Linux platforms. You need to run the appropriate file for your platform by double-clicking on it or using a command line tool. This will launch the job and display its output in a console window.
If you need to run the job in a different context, you need to build a separate copy of the job with the other context selected in the Build Job window. You cannot change the context of an already built job without rebuilding it.
You do not need to build the job with the Context scripts option selected in the Build Job window, edit the script according to the context in which you want to run the job, set the desired context as the default, rebuild the job if you need to run it in a different context, or be prompted for the context. These methods are not correct or available in Talend Studio and may cause errors or unexpected results.
