NEW QUESTION # 16
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. Link A, B and C using On Subject Ok triggers.
- B. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into B.
- C. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into C
- D. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into A.
Answer: A,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 # 18
Which Action on table operations are supported by a tMysqlOutput component?
Choose 3 answers
- A. Drop table
- B. Create table
- C. Replace
- D. Drop table if exists andcreate
- E. Create table if does not exists
Answer: B,D,E
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.

NEW QUESTION # 19
Which characteristics distinguish Traces Debug from Java Debug?
Choose 2 answers
- A. Allow row-by-row inspection of data flows
- B. Require Java development experiences
- C. Requires a separate perspective
- 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.

NEW QUESTION # 20
Which exceptions car be caught using tLogCatcher?
Choose 3 answers
- A. Java Exception
- B. OnbubjobError Exception
- C. tWarn
- D. tDie
- E. tAssertCatcher
Answer: A,C,D
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
Which tab provides lines of code generated for the selected component in Telend Studio?
- A. Outline tab
- B. Code viewer tab
- C. Jobscript tab
- D. Run consult
Answer: B
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 # 22
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. Right-click the trace on the output of the input component and select Show Breakpoint Setup.
- B. Add a breakpoint in the Advanced Settings tab of the Run view.
- C. Open the Debug Run tab of the Run view and click Traces Debug.
- D. Right-click the trace on the output of the input component and select Add Breakpoint.
Answer: A
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 # 23
What determines the name of the tMap output row that delivers join rejects?
- A. The name is predetermined; it is always named Innerjoin Reject.
- B. The name is configurable in the Component view of the tMapcomponent
- C. The name is determined by the output table you create to catch the rejects.
- D. The name is determined by the input table, you create to generate the rejects.
Answer: C
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 # 24
You have a tMap component configured with a single input row1and three outputs: CA, NY, Rejects. The input row1 consists of two columns. Name and State, containing the following data:
All outputs map only the Name column from row1, but CA employs a filter expression, CA.equals(row1.state), while Ny employs a filter expression, NY. Equals(row1,State). All Rejects have no such configuration.
Under these conditions, how does data flow to the outputs?
- A. CA:Thomas Coodge;Calvin Adams; rejects:Andrew Taylor
- B. CA:Thomas Coolidge;Ny:Calvin Adams;rejects:Thomas Coolidge, adrew taylor, Calvin Adame
- C. CA:Thomas Coolidge, Andrew Taylor;Ny:Calvin Adams; rejects:Thomas Coolidge, Andrew Taylor,Calvin Adams
- D. CA:Thomas Coolidge Andrew TyalorlNY;Calvin Adams;rejects;none
Answer: A
Explanation:
Explanation
The tMap component allows you to configure multiple outputs for your data transformation and mapping. You can apply filter expressions on each output to filter out the rows that meet certain criteria. For example, if you want to send only the rows that have CA as the state value to one output, you can use CA.equals(row1.state) as the filter expression for that output. The filter expression evaluates to true or false for each row, and only the rows that evaluate to true are sent to the output. In this case, only Thomas Coolidge and Andrew Taylor have CA as their state value, so they are sent to the CA output. Similarly, only Calvin Adams has NY as his state value, so he is sent to the NY output. The Rejects output has no filter expression, so it receives all the rows from the input by default. However, since there is a conflict between the CA and NY outputs and the Rejects output, only the rows that are not sent to any other output are sent to the Rejects output. In this case, there are no such rows, so the Rejects output receives no data. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend,
NEW QUESTION # 25
You want to use the value of a context variable you defined to configure a component, but you do not remember the exact name. You decide to use the auto-completion feature in Talend Studio Studio to get assistance.
Which keystrokes can you use to trigger auto-completion?
- A. Alt - Space
- B. Ctrl + Alt + Space
- C. Fsc + Space
- D. Ctrl + Space
Answer: D
Explanation:
Explanation
To trigger auto-completion in Talend Studio, you can use the keystrokes Ctrl + Space. This will display a list of possible suggestions based on what you have typed so far. For example, if you type context. and press Ctrl
+ Space, you will see a list of all the context variables you have defined. You can then select the one you want from the list or continue typing to narrow down the choices. Auto-completion can help you avoid typing errors and save time when configuring components or writing expressions. References: Talend Open Studio:

NEW QUESTION # 26
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. tContextLoad component can change the context name in the course of the Job execution.
- C. tContextDump component ran change the context name in the course of the lob execution.
- D. tRunJob component can influence the context in which the child Job runs.
Answer: A,D
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 # 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. Schema
- B. Field separator
- C. Limit
- D. Header
- E. Footer
Answer: A,B,D
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 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 Built-in and set all the relevant properties manually.
- B. Set the Database file to Metadata
- C. Set the Property type, to Repository and use a common DB connection metadata
- D. Set the Property type to Repository and replace the credential1; in each component.
Answer: A
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.

- A. Create an empty Job, then export it as a Joblet by right-clicking it in the Repository.
- B. Right-clicking a space in the Designer and select refactor to Joblect.
- C. Create an empty Jon and use the file menu to save it as Joblet.
- D. Right-click Joblet Designs the Repository and select Create Joblet.
Answer: D
Explanation:
Explanation
To create an empty Joblet, you need to right-click on the Joblet Designs node in the Repository tree view and select Create Joblet option. This will open a dialog box whereyou can enter the name and description of your Joblet and select an icon for it. You can then design your Joblet by adding components and links to it in the Designer workspace.
You cannot create an empty Joblet by creating an empty job, then exporting it as a Joblet by right-clicking it in the Repository, creating an empty job and using the file menu to save it as Joblet, or right-clicking a space in the Designer and selecting refactor to Joblet. 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, [Joblets - 7.3]
NEW QUESTION # 30
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 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.
