Show Suggested Answer

Suggested Answer: C

Trunk-based development is a version control management practice where all developers work on the same trunk of shared code. The trunk is always in a releasable state, which means that at least once a day, developers must integrate their changes to the trunk. This is accomplished through short-lived feature branches related to project tasks. Trunk-based development is a common practice among DevOps teams and part of the DevOps lifecycle since it streamlines merging and integration phases. It also enables continuous integration, which is the practice of merging all development versions of a code base several times a day. Trunk-based development has several benefits, such as:

It reduces the complexity and conflicts of merging long-lived branches

It improves the quality and consistency of the code by enforcing frequent testing and validation

It accelerates the delivery and deployment of new functionality by minimizing the transaction cost and risk

It fosters a culture of collaboration and transparency among developers

I'm with Rosalind on this one. Option C is the way to go. All teams working in one trunk, that's the essence of trunk-based development. Easy peasy.

It makes sense to have all teams committing their code into one trunk.

Ha! Looks like the exam writers are trying to trick us. 'Every team works in their own trunk'? That's just plain silly. Definitely going with Option C.

Hmm, I'm not so sure. Wouldn't Option B make more sense? Teams with similar dependencies working in one branch for the team's work? That sounds like the definition to me.

I guess it depends on how the teams prefer to work. Both Option B and Option C could fit the definition of trunk-based development.

That's true, Option C could also be considered trunk-based development. It's all about how the teams collaborate.

But what about Option C? All teams committing their code into one trunk could also be trunk-based development.

I think Option B is correct. It does make sense for teams with similar dependencies to work in one branch.

I disagree, I believe it's when teams with similar dependencies create one single branch for their work.

I think trunk-based development is when each developer maintains a separate branch.
