Selected Answer: AD

A - correct because some training course may not have any students yet. B - incorrect because roll-up summary only works for master-detail relationship C - incorrect because a detail record will be deleted if a master record is deleted. here is a lookup relationship so no record will be deleted and should not be deleted. D - correct because cross object field will not update in a lookup relationship.

A is right lookup fields can be optional. D is also valid because cross-object field updates don’t work with lookup relationships.

Answers are A and D since the cross object field update is only supported on a master-detail relationship, it's worth mentioning that this can be achieved for a lookup relationship using a flow but the question mentions nothing about flows.

D is incorrect. This article states Cross-object field updates are supported for all custom objects that are children of custom objects in a master-detail relationship. "D" says they are not... So that answer is A and C https://help.salesforce.com/s/articleView?id=sf.workflow_cross_object_field_updates.htm&type=5

Hello Bekahjoy. D is correct. Notice that the question states that the relationship is a lookup version NOT master-detail. Cross-Object if for master-detail.

C to me is incorrect because the user could have a read-only access to the Student record.

Not sure if the comma in "[...] users can ONLY DELETE Students, IF they have access to it." is purposely set, but as per what's written isn't it stating that, should a user be able to visualize Students, he could only delete them instead of maybe add/edit them? Along this line, I went for A & D.

Change my mind A and D - Parent to child relationship. Cross Object Field updates are possible for Lookup Relationships using Process builder.

A & C - A cross-object formula also works with lookup relationships.

A & C. A is because not all students will attend all trainings. C is because owner of a training may not be an owner of student record and since they are loosely related, record access may be different. D is definitely false because cross-object field updates between any related records can be achieved by using Flow.
