Exam Certified Platform App Builder topic 1 question 355 discussion

A-UC requires a report that shows the related custom objects of Postings, you'll need to create custom report types. Standard report types won't provide the ability to traverse the custom relationships you've created. B-Lookup relationships are appropriate when you want to create a many-to-one relationship between Postings and Positions, and Postings and Websites. C-This allows a single Posting to be related to one Position and one Website.Master-detail relationships create a strong ownership dependency. If a Position or Website record is deleted, the related Postings would also be deleted. This is likely not the desired behavior.D-Standard report types will not include custom objects or relationships. Therefore, they cannot be used to create the required report.

It should be C and not B, because if you delete a Posting record you also want the related record on the child objects to de removed

If C is right, which all claim, then D is the other correct answer because: When custom objects and custom master detail relationships are created Salesforce will often automatically create "standard" report types.

I have tested this too and if you select available for reporting in the "Other Reports" section you will find the report Postings with Positions and Websites. C & D are the correct answers.

I've tested it. I've created a Postings object with Master-Detail field to both Positions and Websites and no standard report type was created. So it seems to be AC is the right answer.

I am confused on this question. Can anyone explain further?

C and D Report type would be created automatically in Master-Detail Relation

I think C and D is the right answer. The report needs to show the records that have always related records and this is true for standard report type. No need so for custmos report type where you can show records if they have related records or not

C D Is the right answer.

Why Master Detail?
