QUESTION: 21

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?

Fsc + Space
Ctrl + Alt + Space
Ctrl + Space
Alt - Space

Answer(s): C

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.

QUESTION: 22

Which factors can affect the context in which a Job is run? Choose 2 answers

Context chosen by the developer when running the Job. Context available in the Basic Run tab of Run Job section.
tContextLoad component can change the context name in the course of the Job execution.
tContextDump component ran change the context name in the course of the lob execution.
tRunJob component can influence the context in which the child Job runs.

Answer(s): 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.

QUESTION: 23

Which statements are true about using the Implicit Context Load feature in Talend Studio? Choose? answers

Loads context parameters from a database table only
Loads context parameters dynamically at the time of Job execution
Loads context parameters from both a delimited file and a database table
Loads context parameters from a delimited file only

Answer(s): B,C

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.

QUESTION: 24

You are building a Job that consists of two subJobs being sequentially executed I he first subJob completes successfully.
Which component in the first subJob triggers the execution of the second subJob?

Start component
Final component
Input component
Any component

Answer(s): A

Explanation:

The Start component in a subjob triggers the execution of the next subjob in a sequential order. The Start component is used to define where a subjob begins and to link it with other subjobs within a job. The Start component has only one output link that can be connected to any other component in the same subjob or to another Start component in another subjob.
When a subjob completes successfully, it sends an OnSubjobOk trigger to its Start component, which then activates the next subjob linked to it. The Final component, on the other hand, is used to define where a subjob ends and to perform some actions after its completion, such as sending an email or logging a message. The Final component has no output link and does not trigger any other subjob. The Input component and any other component in a subjob do not trigger any other subjob by themselves, unless they are connected to a Start component through an output link or an OnComponentOk trigger.
