- C. Repository
- D. Code
Answer: A
Explanation:
Explanation
The design workspace in Talend Studio allows the user to graphically connect components in a Job to run a dataflow process. The design workspace is the main area where the user can design the data integration logic by dragging and dropping components from the palette and linking them with connectors. The design workspace also shows the schema of each component, which defines the structure and type of the data.
NEW QUESTION # 15
You created a Job to process a customer database. Next, you want to debug the Job using Traces Debug and pause the execution when it encounters any records for customers residing in the state of California.
- A. Open the Debug Run tab of the Run view and click Traces Debug.
- B. Right-click the trace on the output of the input component and select Add Breakpoint.
- C. Add a breakpoint in the Advanced Settings tab of the Run view.
- D. Right-click the trace on the output of the input component and select Show Breakpoint Setup.
Answer: D
Explanation:
Explanation
To debug a job using Trace Debug mode and pause the execution when it encounters any records for customers residing in the state of California, you need to right-click on the trace on the output of the input component and select Show Breakpoint Setup option. Trace Debug mode is a feature that allows you to trace each row processed by your job components and see the values of each column in each row. You can access this mode by opening the Debug Run tab of the Run view and clicking on Trace Debug button. A trace is a link that shows the data flow between components in your job design workspace.
The Show Breakpoint Setup option allows you to set a breakpoint on a trace based on a condition or an expression. A breakpoint is a point where the execution of your job pauses and waits for your action. You can use breakpoints to inspect your data or debug your logic at specific points of your job execution. You can access this option by right-clicking on a trace on your job design workspace and selecting Show Breakpoint Setup. This will open a dialog box where you can enter a condition or an expression for your breakpoint.
For example, if you want to pause your job execution when it encounters any records for customers residing in the state of California, you can enter this condition for your breakpoint:
row1.state == "CA"
This will make your job stop at the trace where this condition is met and show you the values of each column for that row.
You do not need to add a breakpoint in Advanced settings tab of Run view, open Debug Run tab of Run view and click Trace Debug button, or right-click on trace on output of input component and select Add Breakpoint option. These options are not used to set breakpoints based on conditions or expressions. The Advanced settings tab of Run view is used to configure advanced settings for your job execution, such as JVM arguments, statistics parameters, implicit context load parameters, etc. The Debug Run tab of Runview is used to access Trace Debug mode, but not to set breakpoints. The Add Breakpoint option is used to add a simple breakpoint on a trace without any condition or expression.

NEW QUESTION # 16
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: D
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 # 17
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. Create DB Connections metadata to describe the database connection.
- B. Retrieve schemas from the database connection.
- C. Add a tMap component handle and convert DB Types.
- D. Drag the Db Connection metadata into the Designer to read from the database component.
- E. Add a tCreatTable component to create a table in the database.
Answer: A,B,D
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.

Choose2answers
- A. TabletoTable
- B. FileToDatabase.
- C. JobletToFile
- D. TahleToFile
Answer: A,D
Explanation:
Explanation
Talend Studio provides templates that allow you to create ready-to-run Jobs for common scenarios, such as Table to Table, File to Database, Table to File, etc. You can access these templates from the Repository > Job Designs > Create Job from Template menu. Joblet to File is not a valid template name.
NEW QUESTION # 19
What is the generic Input component used for in a Joblet design?
- A. Triggering a Joblet
- B. Triggering a subJob
- C. Carrying data into a Joblet
- D. Carrying data into a subJob
Answer: C
Explanation:
Explanation
The generic Input component used for in a Joblet design is the tJobletInput component. This component is used to carry data into a Joblet from another component in the job that contains the Joblet. A Joblet is a reusable piece of a job that can be used in multiple jobs as a single component. A Joblet can have one or more input and output flows that connect it with other components in a job. To create these flows, you need to use generic input and output components, such as tJobletInput, tJobletOutput, tJobletTriggerInput, and tJobletTriggerOutput. These components allow you to define schemas and triggers for your Joblet without depending on specific components.
The tJobletInput component is not used for triggering a Joblet, triggering a subjob, or carrying data into a subjob. These are different concepts and functionalities in Talend Studio. A trigger is a link that activates a subjob or a component based on a condition or an event. A subjob is a part of a job that consists of one or more components connected by data flows or triggers. A subjob can be triggered by another subjob using triggers such as OnSubjobOk, OnSubjobError, Run if, etc. A subjob can also carry data into another subjob using data flows such as main, lookup, reject, etc. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [tJobletInput properties - 7.3], [Joblets - 7.3], [Triggers - 7.3]
NEW QUESTION # 20
Which Action on table operations are supported by a tMysqlOutput component?
Choose 3 answers
- A. Create table if does not exists
- B. Drop table
- C. Drop table if exists andcreate
- D. Create table
- E. Replace
Answer: A,C,D
Explanation:
Explanation
The tMysqlOutput component is used to write data into a MySQL database table. The Action on table parameter of this component allows you to specify what operation to perform on the table before loading data into it. The Action on table parameter supports the following operations:
Drop table if exists and create: This operation drops the table if it already exists in the database and creates a new one with the same name and structure as defined in the schema.
Create table: This operation creates a new table in the database with the name and structure as defined in the schema. If a table with the same name already exists, an error will be raised.
Create table if does not exist: This operation creates a new table in the database with the name and structure as defined in the schema only if there is no table with the same name already existing in the database. If a table with the same name already exists, no action will be taken.
The Action on table parameter does not support the following operations:
Replace: This is not an operation on the table, but on the data. The Replace parameter of the tMysqlOutput component allows you to specify whether to replace existing rows in the table with new rows based on a key attribute or to insert new rows only.
Drop table: This is not an operation on the table, but on the database. The Drop table parameter of the tMysqlConnection component allows you to specify whether to drop the table after closing the connection or not.

- C. ((Integer)globalMap.get(''tFieldInputDelimited_1NB_LINES''))===0
- D. ((Integer)globalMap.get(''tFieldInputDelimited_1NB_LINES''))--0
Answer: A
Explanation:
Explanation
To reference the value of a context variable you defined, you can use the syntax context.variable_name, where variable_name is the name of the context variable. For example, if you have a context variable named path, you can reference its value by using context.path. You do not need to specify the context name (such as test or prod) or use parentheses or brackets around the variable name.

NEW QUESTION # 22
Which characteristics distinguish Traces Debug from Java Debug?
Choose 2 answers
- A. Allow row-by-row inspection of data flows
- B. Requires a separate perspective
- C. Require Java development experiences
- D. Supports breakpoints based on input data condition
Answer: A,D
Explanation:
Explanation
Trace Debug and Java Debug are two modes that allow you to debug your jobs in Talend Studio. Trace Debug mode allows you to trace each row processed by your job components and see the values of each column in each row. Java Debug mode allows you to debug your job code in Java or Perl and see the values of each variable or expression in your code.
The characteristics that distinguish Trace Debug from Java Debug are:
Trace Debug mode allows row-by-row inspection of data flows, while Java Debug mode does not. Data flows are the links that show the data transfer between components in your job design workspace. In Trace Debug mode, you can see the data flow on each trace and inspect the values of each column for each row processed by your job. You can also use filters to display only the rows that match a condition or an expression. In Java Debug mode, you cannot see the data flow on each trace or inspect the values of each column for each row.
Trace Debug mode supports breakpoints based on input data condition, while Java Debug mode does not. Breakpoints are points where the execution of your job pauses and waits for your action. You can use breakpoints to inspect your data or debug your logic at specific points of your job execution. In Trace Debug mode, you can set breakpoints on traces based on a condition or an expression that involves input data columns. For example, you can set a breakpoint to pause your job when a customer name contains a certain string or when a product price exceeds a certain value. In Java Debug mode, you can only set breakpoints on lines of code based on a condition or an expression that involves variables or expressions.
The characteristics that do not distinguish Trace Debug from Java Debug are:
Both modes require a separate perspective. A perspective is a set of views and editors that are arranged in a specific way to support a specific task. In Talend Studio, you can switch between different perspectives, such as Integration, Debug, Profiling, etc. To use Trace Debug mode, you need to switch to the Debug perspective by clicking on the Open Perspective button and selecting Debug. To use Java Debug mode, you need to switch to the Java perspective by clicking on the Open Perspective button and selecting Java.
Neither mode requires Java development experience. Although Java Debug mode allows you to debug your job code in Java or Perl, you do not need to have Java development experience to use it. You can use the graphical interface of Talend Studio to design your job components and properties without writing any code. You can also use the Code view to see the generated code of your job in Java or Perl and modify it if needed. However, you do not need to write any code from scratch or understand all the details of the code to use Java Debug mode.

Explanation:
Explanation
A middleware application is a software that acts as a mediator between different data sources and data consumers. It can normalize data and bring it into a master data pool, which is a centralized repository of consistent and quality data. This can help a data professional to combine multiple data sources into a relational database to improve their business efficiency. A middleware application can also provide data integration services such as data transformation, validation, cleansing, and enrichment. References: What is Data Integration?, What is Middleware?
NEW QUESTION # 24
Which tab provides lines of code generated for the selected component in Telend Studio?
- A. Run consult
- B. Jobscript tab
- C. Code viewer tab
- D. Outline tab
Answer: C
Explanation:
Explanation
The code viewer tab in Talend Studio provides lines of code generated for the selected component in a Job. It shows the code in the language of the component, such as Java or Perl. The code viewer tab allows the user to view and edit the code, as well as copy and paste it to another editor. The code viewer tab also displays errors and warnings related to the code. References: Code viewer tab
NEW QUESTION # 25
How are contexts defined?
- A. Talend Studio defines a default context, and you can define more as needed.
- B. In addition to a default context, Talend Studio defines a list of standard contexts you can use in your Ions.
- C. You must define the contexts
- D. They are automatically defined by the types of components used in the Job.
Answer: C
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. Right-click the Job in the Repository and select Build Job
- B. Click the Export button in the Edit Properties window.
- C. Select Save As on the main File menu
- D. Right-click the Job in the Repository and select Export items.
Answer: A
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:

Which file should you edit to enable SSL for a JobServer?
- A. Conf/TalendServer.properties
- B. Conf/server.xml
- C. Jsl_stati64.ini
- D. Conf/TalendJobServer.properties
Answer: D
Explanation:
Explanation
To enable SSL for a JobServer, you need to edit the conf/TalendJobServer.properties file. A JobServer is a server application that allows you to execute jobs remotely from Talend Studio or Talend Administration Center. The conf/TalendJobServer.properties file contains various configuration parameters for your JobServer, such as port number, log level, security options, etc. To enable SSL for your JobServer, you need to set the ssl parameter to true and provide the path and password of your keystore file that contains your SSL certificate.
You do not need to edit conf/TalendServer.properties, conf/server.xml, or jsl_static64.ini files. These files are not related to JobServer configuration or SSL settings. The conf/TalendServer.properties file is used to configure Talend Administration Centersettings, such as database connection, LDAP authentication, email notification, etc. The conf/server.xml file is used to configure Tomcat server settings, such as connectors, realms, valves, etc. The jsl_static64.ini file is used to configure Java Service Launcher settings, such as service name, description, startup type, etc. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Configuring Talend JobServer - 7.3], [Configuring Talend Administration Center - 7.3],

NEW QUESTION # 28
You are collaborating on a project with other developers using talend best practices.
When should you use a tag?
- A. Fixing hugs or enhancements.
- B. Denoting a milestone in the lifecycle of a project
- C. Capturing snapshot of a codebase that requires ongoing maintenance.
- 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 # 29
You need to call a different Job within a Job you are developing.
Which mechanism allows you to pass the parameters to the lob you want to call?
- A. Java Function paramters
- B. Context parameters
- C. CommandLine options
- D. File
Answer: B
Explanation:
Explanation
To call a different job within a job you are developing, you can use the tRunJob component. This component allows you to execute another job as a subjob within a parent job. To pass the parameters to the job you want to call, you can use the context parameters. Context parameters are variables that can store values that can be changed at runtime or between different contexts. You can define context parameters in the Contexts tab of your job and assign them values for each context. You can also pass context parameters from the parent job to the child job by using the Context Param tab of the tRunJob component. This way, you can parameterize the properties or expressions of the child job with the values from the parent job.
You do not need to use a file, command line options, or Java function parameters to pass parameters to a different job. These methods are not supported by Talend Studio and may cause errors or unexpected results.

NEW QUESTION # 30
What determines the name of the tMap output row that delivers join rejects?
- A. The name is determined by the output table you create to catch the rejects.
- B. The name is determined by the input table, you create to generate the rejects.
- C. The name is configurable in the Component view of the tMapcomponent
- D. The name is predetermined; it is always named Innerjoin Reject.
Answer: A
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 # 32
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 configuredbetween 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?
- A. If an output is configured to collect inner join rejects, the data flows to that output as well as the main output.
- B. If an output is not configured to collect inner Join rejects, the data flows to the main output.
- C. If an output is not configured to collect inner join rejects, an error condition is raises.
- D. If an output is configured to collect inner join rejects, the data flows only to that output.
Answer: D
Explanation:
Explanation
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 capabilities does Traces Debugprovide?
Choose 2 answers
- A. Advancing one column at a time
- B. Advancing one row at a time
- C. Filtering which data is propagated by a flow
- D. Breaking on a selected line of code
- E. Breaking when an input column fulfills a condition
Answer: B,E
Explanation:
Explanation
Trace Debug mode is a feature that allows you to trace each row processed by your job components and see the values of each column in each row. You can access this mode by opening the Debug Run tab of the Run view and clicking on Trace Debug button.
The capabilities that Trace Debug mode provides are:
Breaking when an input column fulfills a condition. You can set breakpoints on traces based on a condition or an expression that involves input data columns. For example, you can set a breakpoint to pause your job when a customer name contains a certain string or when a product price exceeds a certain value. To set a breakpoint based on a condition, you need to right-click on a trace on your jobdesign workspace and select Show Breakpoint Setup option. This will open a dialog box where you can enter a condition or an expression for your breakpoint.
Advancing one row at a time. You can advance the execution of your job one row at a time by using the Step Over button in the toolbar of the Run view. This will allow you to see how each row is processed by your job components and how it affects the output data.
The capabilities that Trace Debug mode does not provide are:
Filtering which data is propagated by a flow. You cannot filter which data is propagated by a flow in Trace Debug mode. A flow is a link that shows the data transfer between components in your job design workspace. In Trace Debug mode, you can see the data flow on each trace and inspect the values of each column for each row processed by your job. However, you cannot change which rows are propagated by a flow based on a condition or an expression.
Advancing one column at a time. You cannot advance the execution of your job one column at a time in Trace Debug mode. You can only advance the execution of your job one row at a time by using the Step Over button in the toolbar of the Run view. This will allow you to see how each row is processed by your job components and how it affects the output data. However, you cannot see how each column is processed by your job components and how it affects the output data.
Breaking on a selected line of code. You cannot break on a selected line of code in Trace Debug mode.
You can only break on a trace based on a condition or an expression that involves input data columns.
To break on a selected line of code, you need to use Java Debug mode. Java Debug mode allows you to debug your job code in Java or Perl and see the values of each variable or expression in your code.

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.
