Adobe AD0-E716 Exam - Topic 12 Question 54 Discussion

Actual exam question for Adobe's AD0-E716 exam

Question #: 54
Topic #: 12

An Adobe Commerce developer has installed a module from a third-party vendor. This module fires a custom event named third_party_event_after and also defines an observer named third_party_event_after_observer that listens to that event. The developer wants to listen to this custom event in their own module but wants to execute their observer's logic after the third_party_event_after_observer observer has finished executing.

What would the developer do to ensure their observer runs after the observer defined by the third-party module?

AEnsure the third-party module is listed in the <sequence> node of the developer's module.xmi file.

BSet the sort order of the new observer to be less than that of the third-party vendor's observer.

CThis is not possible as observers listening to the same event may be invoked in any order.

Show Suggested Answer

Suggested Answer: B

To ensure that the developer's observer runs after the observer defined by the third-party module, they need to set the sort order of the new observer to be less than that of the third-party vendor's observer.

The sort order is a number that is assigned to each observer. The lower the number, the earlier the observer will be executed.

For example, if the third-party vendor's observer has a sort order of 10, the developer's observer would need to have a sort order of 9 or lower.

C) is just plain wrong. The order of observer execution can definitely be controlled using the sort order.

I agree with B. It's the only way to guarantee the order of execution for observers listening to the same event.

B) is the correct answer. Setting the sort order of the new observer to be less than that of the third-party vendor's observer will ensure that the developer's observer runs after the third-party observer.

I thought observers could be executed in any order, but maybe there's a way to set priorities that I'm missing.

I recall a similar question where we had to manage observer priorities, and it seems like option B aligns with that concept.

I'm not entirely sure, but I feel like the sequence node is more about module dependencies rather than observer execution order.

I think I remember that the sort order can control the execution sequence of observers, so option B might be the right choice.

Okay, I think I've got it. B is the right answer. By setting the sort order of our observer to be less than the third-party one, we can ensure our logic runs after theirs. Nice, I feel confident about this now.

I'm not too sure about this one. The question says it's not possible to control the order of observers listening to the same event, so I'm a bit hesitant to go with B. Maybe there's some other trick I'm missing here.

Ah, I see what's going on here. The key is that we want our observer to run after the third-party one, so B is definitely the way to go. Setting the sort order is the best way to control the execution order of the observers.

I'm a bit confused on this one. I know we need to make sure our observer runs after the third-party one, but I'm not sure if setting the sort order is the right approach. Hmm, let me think this through a bit more.

I think the answer is B. Setting the sort order of the new observer to be less than the third-party vendor's observer should ensure my observer runs after theirs.
