Talend-Core-Developer Exam - Topic 5 Question 14 Discussion

Posted by Herschel on Nov 22, 2025 at 07:08 AM

You are collaborating on a project with other developers using talend best practices.

When should you use a tag?

Suggested Answer: D

Tags are used to mark specific points in the development lifecycle of a project. This can be done for a variety of reasons, such as:

To mark the completion of a major feature or release

To mark the start of a new development phase (e.g., QA, production)

To mark a known good state of the codebase (e.g., before a risky change)

Tags can be used to create branches, which can then be used to develop and test new features or bug fixes. They can also be used to deploy the codebase to different environments (e.g., development, staging, production).

Examples of when to use a tag:

When you are ready to release a new version of your application to production.

When you have completed a major feature or milestone in the development of your application.

Before making a risky change to your codebase, such as a database migration or refactoring.

When you need to deploy your application to a different environment, such as staging or production.

Benefits of using tags:

Tags can help you to keep track of the different versions of your codebase.

Tags can help you to roll back to a previous version of your codebase if necessary.

Tags can help you to deploy your codebase to different environments.

Tags can help you to collaborate with other developers more effectively.

I’m a bit confused about this one. I can see how tags could apply to fixing bugs too, but I think that’s more about commits than tags, right?
LI
Linn 9 months ago
I think we practiced a question similar to this, and it emphasized using tags for major releases. So, I’m leaning towards C.
AL

I’m not entirely sure, but I feel like tags could also be useful for ongoing maintenance, which might relate to option A.

I'm pretty confident that tags are used to denote major or minor releases, so I'm going to go with option C.
JO

I'm not too familiar with Talend best practices, but from what I remember, tags are used to fix bugs or make enhancements. I'll go with option B.
JE
Jesse 10 months ago
Okay, let me see. I think tags are used to mark milestones in a project's lifecycle, so I'll go with option D.

I remember we discussed tags in our last study group, and I think they’re mainly for marking significant points in the project, like releases. So, maybe C or D?
CH

C) Denoting major or minor releases.

Fixing bugs should be noted, but tagging feels less critical there.
JA

Hmm, I'm a bit confused. I thought tags were for capturing a snapshot of the codebase, but I'm not sure if that's for ongoing maintenance or not. I'll have to think this through.
