Adobe Exam AD0-E703 Topic 7 Question 48 Discussion

Actual exam question for Adobe's AD0-E703 exam

Question #: 48
Topic #: 7

In a code review of a merchant's site you have discovered that there are multiple observers for the checkout_submit_all_after event. After closer inspection, you notice one of these observers is relying on the others being executed before it is called.

What risk does this pose, and how can it be mitigated?

AThere is no risk posed as long as each event observer specifies a correct sortOrder. Nothing needs to be changed.

BEvent observers are fired in alphabetical order of the observer name. There is no risk here.

CMagento only supports one observer per event. These observers will need to be combined into a single point of customization.

DOrder of listener execution cannot be guaranteed, resulting in a fragile implementation. This code should be re-worked using plugins
