NEW QUESTION # 24
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 C
- B. Link A, B and C using On Subject Ok triggers.
- C. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into B.
- D. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into A.
Answer: A,B
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 # 25
In the tMap component, where do you set up a filter on the input fields?
- A. Match Model parameter field for one of the main inputs
- B. Expression filter in the output table
- C. Expression field for a single column of the output
- D. Match Model parameter field for fine of the inputs
Answer: B
Explanation:
Explanation
The tMap component allows you to set up a filter on the input fields by using the Expression filter in the output table. The Expression filter is a field where you can enter a logical expression that evaluates to true or false for each input row. For example, if you want to filter out the rows that have null values in a certain column, you can use row1.column != null as the expression filter for that output. The expression filter applies to all the input fields of the row, not just a single column. You cannot set up a filter on the input fields by using the Match Model parameter field for one of the inputs or outputs, as this field is used to define how to match rows between different inputs or outputs based on a key attribute.

NEW QUESTION # 26
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?
- A. Set the Property type to Repository and replace the credential1; in each component.
- B. Set the Property type, to Repository and use a common DB connection metadata
- C. Set the Database file to Metadata
- D. Set the Property type to Built-in and set all the relevant properties manually.
Answer: D
Explanation:
Explanation
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.

NEW QUESTION # 27
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 main input source will always be placed on top by default hut ran be dragged to any position.
- D. The order in which the input sources appear on the map does not matter, provided the joins are configured correctly.
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 # 28
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. File
- B. Context parameters
- C. CommandLine options
- D. Java Function paramters
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. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [tRunJob properties - 7.3], [Contexts - 7.3]
NEW QUESTION # 29
A Job has two contexts defined: lest (the default) and Prod, and two context variables defined: path and server.
Which expression should you use to reference the path?
- A. contex,(test.Prod).path
- B. context(path)
- C. context.Tfblpdtr1
- D. context, path
Answer: D
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 # 30
Which types of SQL templates does Talend Studio provide?
Choose 2 answers
- A. System-defined SQL templates
- B. Use-defined SQL templates
- C. System SQL templates
- D. Custom SQL templates
Answer: B,C
Explanation:
Explanation
Talend Studio provides two types of SQL templates: system SQL templates and user-defined SQL templates.
SQL templates are predefined SQL queries that can be used in various components that execute SQL statements, such as tDBInput, tDBRow, tDBOutput, etc. System SQL templates are provided by Talend Studio and cover common SQL operations, such as creating, dropping, or altering tables, inserting, updating, or deleting data, etc. User-defined SQL templates are created by the user and can be customized according to specific needs. User-defined SQL templates can be created by using the SQL Templates view in Talend Studio and can be organized into categories and subcategories. There are no custom SQL templates orsystem-defined SQL templates in Talend Studio. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [SQL Templates - 7.3]
NEW QUESTION # 31
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. Heading the time stamps from the execution console in the Run view.
- B. Comparing time stamp in Trace Debug mode.
- C. Observing the execution times that annotate the flows in the Designer.
- D. Observing the execution time in the Code view.
Answer: A,C
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 # 32
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, copy the Branch 1 Job, switch to Branch 2, and paste the Job into Branch 2.
- B. Switch to Branch1, copy lob 1, switch to Branch 2, and paste Job 1 over Job 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. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Copy to branch - 7.3]
NEW QUESTION # 33
You have two Talend Jobs. Job A need to call Job B. After Job B is complete, processed data stored in the tBufferOutput buffer memory must be transferred back to Job A.
How can you achieve this requirement?
- A. Select the Propagate the child result to output schema in Advanced settings of the tRunJob when calling Job B from Job B.
- B. Select the Transmit whole context in Advanced settings of the tRunJob when calling Job B from Job A.
- C. Select the Transmit whole context in the basic settings of the tRunJob when calling Job B from Job A.
- D. Select the Propagate the child result to output schema in the Basicsettings of the tRunJob when calling B from Job A.
Answer: A
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.
To transfer processed data stored in the tBufferOutput buffer memory back to the parent job, you need to select the Propagate the child result to output schema option in the Advanced settings of the tRunJob component. This option allows you to retrieve the data from the tBufferOutput component of the child job and send it to an output row of the parent job. The tBufferOutput component is used to store data in memory without writing it to disk or database. You can use this component to optimize the performance and memory usage of your job.
You do not need to select the Transmit whole context option in either Basic or Advanced settings of the tRunJob component. This option allows you to pass all the context parameters from the parent job to the child job without specifying them individually. This option does not affect the data transfer from the tBufferOutput component. You also do not need to select the Propagate the child result to output schema option in Basic settings of the tRunJob component, as this option is only available in Advanced settings.

Which statements are true about using the Implicit Context Load feature in Talend Studio?
Choose? answers
- A. Loads context parameters from a delimited file only
- B. Loads context parameters from a database table only
- C. Loads context parameters dynamically at the time of Job execution
- D. Loads context parameters from both a delimited file and a database table
Answer: C,D
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.

- D. Manually collect the data from various source interfaces,thenclean and combine the data into one warehouse.
Answer: A
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 # 37
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. Add a tCreatTable component to create a table in the database.
- C. Create DB Connections metadata to describe the database connection.
- D. Drag the Db Connection metadata into the Designer to read from the database component.
- E. Add a tMap component handle and convert DB Types.
Answer: A,C,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.

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

Which method allows you to execute the compiled Job Talend Studio?
- A. Right-click the Job in the Repository and select Export items.
- B. Select Save As on the main File menu
- C. Click the Export button in the Edit Properties window.
- D. Right-click the Job in the Repository and select Build Job
Answer: D
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/server.xml
- B. Conf/TalendServer.properties
- C. Conf/TalendJobServer.properties
- D. Jsl_stati64.ini
Answer: C
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 # 43
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 Out you want to apply the schema, changes to the previous component in the Job.
- C. Confirm that you want to apply the schema changes to the next component in the Job.
- D. Confirm that you want to apply the schema changes to both the previous and next components 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.
