Actual exam question for Talend's Data-Integration-Developer exam
Question #: 10
Topic #: 4
[All Data-Integration-Developer Questions]

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?

Show Suggested Answer Hide Answer
Suggested Answer: A

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.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Start properties - 7.3], [Final properties - 7.3]

Agreed, Final component makes the most sense!

It's definitely the Final component that triggers the next subJob.

I’m leaning towards the Final component too, but I wonder if the Input component could also play a role in triggering the next job.

I'm a bit confused; could it be any component? I feel like I read something about that in the study materials.

I remember practicing a similar question, and I think the Start component is what triggers the next job.

I think the answer might be the Final component since it usually indicates the end of a process, but I'm not entirely sure.

Hmm, I'm leaning towards the Final component as the answer, since that would make sense as the component that signals the completion of the first subJob and allows the second one to start. But I'll double-check the other options just to be sure.

I think the key here is understanding the relationship between the two subJobs. The question is asking which component in the first subJob is responsible for initiating the second subJob, so I'll need to focus on that connection.

I'm a bit confused on this one. Is it the Start component that kicks off the whole process, or is there some other component that specifically triggers the second subJob?

Okay, let me see... The question says the second subJob is executed after the first one completes successfully, so I'm guessing the component that triggers the second subJob is the one that signals the completion of the first one.

Hmm, this seems like a tricky one. I'll need to think through the sequence of the subJobs and how they're connected.

This seems like a straightforward question about the requirements for the new inventory management system. I think the key is to focus on the exceptional condition that must be proven, as stated in the question.

This looks like a classic access list configuration question. I'll need to carefully analyze the network diagram and the requirements to determine the correct interface to apply the access list.

I'm a little confused on this one. I know we shouldn't store credentials in the source code, but I'm not sure about the other options. I'll have to review the material on secure credential storage before I decide.

This looks like a straightforward question. The Get Metadata activity should be able to retrieve the DateTime of the files, which can then be used to insert the data into the Table1 with the additional DateTime column.

Hmm, I'm a bit unsure about this one. The company has a good credit rating, so that's a plus, but I'll need to think through the pros and cons of each borrowing method to determine the most cost-effective approach.

In that case, maybe the final component would be the one to trigger the second subJob.

I think using any component to trigger the next subJob might not be reliable in all cases. The Start component is specifically designed for this purpose.
