Question #1 (Topic: demo questions)

You are building a Job to run outsode Talend Studio that must run on both Linux and Windows.
Which action should you take when building the Job?

A.
Select Build Job because Jobs are runnable on all platforms
B.
Specify All for the Shell launcher option in the Build Job windows.
C.
Configure the Job properties building the Job.
D.
Build one package for each platform.
Correct Answer: B
Explanation:
To build a job to run outside Talend Studio that must run on both Linux and Windows, you
need to select Build Job because jobs are runnable on all platforms. The Build Job 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 specify All for the Shell launcher option in the Build Job window,
configure the job properties before building the job, or build one package for each platform.
These methods are not necessary or available in Talend Studio and may cause errors or
unexpected results.
Question #2 (Topic: demo questions)

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.
Context parameters
B.
File
C.
CommandLine options
D.
Java Function paramters
Correct Answer: A
Explanation:
To call a different job within ajob 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, youcan 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 tabof 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.
Question #3 (Topic: demo questions)

You have a Job that uses a tFileInputDelimited component to extract data from an input file. You built a
spate subjob, called W, to handle the condition when the input file is empty.
Which condition syntax is correct for the Run if connection?

A.
((Integer)globalMap.get(‘’tFieldInputDelimited_1NB_LINES’’))=0
B.
((Integer)globalMap.get(‘’tFieldInputDelimited_1NB_LINES’’))--0
C.
((Integer)globalMap.get(‘’tFieldInputDelimited_1NB_LINES’’))-0
D.
((Integer)globalMap.get(‘’tFieldInputDelimited_1NB_LINES’’))===0
Correct Answer: C
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.
Question #4 (Topic: demo questions)

Which section in Talend Studio allows you to graphically connect components in a Job to run a dataflow
process?

A.
Design workspace
B.
Component view
C.
Repository
D.
Code
Correct Answer: A
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.
Question #5 (Topic: demo questions)

Which factors can affect the context in which a Job is run?

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.
Correct Answer: A, D
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.
