Which two considerations should be made?

Show Answer Hide Answer
Correct Answer: A, B

The two considerations that should be made are: The Star records are all required to have an existing value in their Galaxy field. This is a prerequisite for converting a lookup relationship to a master-detail relationship. A lookup relationship is an optional relationship that links two objects together, but does not enforce referential integrity or cascade delete. A master-detail relationship is a required relationship that links two objects together and enforces referential integrity and cascade delete. To convert a lookup relationship to a master-detail relationship, all child records must have a value in their lookup field that references an existing parent record. The Galaxy object has fewer than two existing master-detail relationships. This is another prerequisite for converting a lookup relationship to a master-detail relationship. An object can have up to two master-detail relationships with other objects and can act as both the parent and child in different relationships. To convert a lookup relationship to a master-detail relationship, the parent object must have fewer than two existing master-detail relationships with other objects. The Galaxy object is required to contain existing roll-up summary fields is not a valid consideration, as it is not related to converting a lookup relationship to a master-detail relationship.

Question No. 4

An app builder has modified a Lightning record page for a case and has added an email button item to the page layout; however, users are unable to see the new item on the layout.

What are two potential reasons why users are unable to view the item on the Case Lightning record page?

Choose 2 answers

Show Answer Hide Answer
Correct Answer: A, B

The email button item will not be visible on the Lightning record page if the page layout includes the case feed component or if the email button contains JavaScript. The case feed component replaces the standard buttons on the page layout with actions in the feed. The email button item will not work if it contains JavaScript because JavaScript buttons are not supported in Lightning Experience.
