Talend-Core-Developer Practice Questions

To add a Joblet to your Talend Job, you can use one of these options:

Type the Joblet name on the Studio canvas, then select it from the Palette drop-down menu. This will create a Joblet container on your canvas that contains all the components and links of your Joblet.

Drag the Joblet from Repository tree view to designer canvas. This will also create a Joblet container on your canvas that contains all components and links of your Joblet.

Drag Joblet from Palette to design workspace. This will open a dialog box where you can select an existing Joblet from Repository or create a new one.

You cannot use a tRunJob component and select Joblet from drop-down menu, nor right-click Joblet from Palette and select Add option. 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]

Add a task and then run the task (Option A):

Once the task is created, you can run it manually or schedule it for execution.​

Select the artifact name, add and configure a task, then run the task (Option D):

In TMC, go to theArtifactssection to view your published Jobs.​

Select the desired artifact and click onAdd Task.​

Option C:While you can select and configure an existing task, the initial step requires creating the task associated with the artifact.​
