1
Q
What is a Business Object?
A
Business objects, including Account, Contact, Opportunity, and Case, are provided by Salesforce, which means that custom objects are not required for them.
2
Q
What are custom Objects used for?
A
Custom objects are used to store information specific to the company or organization, such as properties or employees.
3
Q
What are the different types of relationships?
A
Lookup
Master Detail
Many to Many
External Lookup
Indirect Lookup
Hierarchical
4
Q
While objects in a lookup relationship are loosely coupled, objects in a master-detail relationship are tightly coupled. True or False?
A
True
5
Q
What does a lookup relationship do?
A
Link two different objects in a loose relationship where the parent and child records have independent sharing settings and are deleted separately.
6
Q
What does a master detail relationship do?
A
Link two different objects in a tight relationship where the sharing settings of the child record depend on the parent’s, and deleting the parent also deletes the child record.
7
Q
While a many-to-many relationship requires a third object in order to create the relationship, the <Blank> object is only what is needed in a hierarchical relationship</Blank>
A
User Object
8
Q
What does a many to many relationship do?
A
Link two objects such that a record of one object can be related to multiple records of another and vice versa.
9
Q
What does a hierarchical relationship do?
A
Create a lookup field to associate one user with another that does not directly or indirectly refer to itself.
10
Q
What does a External Lookup relationship do?
A
Link a child standard, custom, or external object to a parent external object using the standard External ID field.
11
Q
What does an Indirect Relationship do?
A
Link a child external object to a parent standard or custom object through a custom unique, External ID field.
12
Q
Parent and child objects have independent sharing settings. Each object has an owner field. True or False?
A
True for lookup relationships
False for master detail
13
Q
Records of the child object will appear in a related list on the parent record. True or False?
A
True
14
Q
Can you delete the parent of a lookup relationship?
A
The parent can be prevented from being deleted if children exist. Children can also be deleted when parent is deleted (requires Salesforce support).
15
Q
Do Lookup relationships support roll-up summary fields?
A
Lookup relationships can link two objects together. They are similar to master-detail relationships but they do not support roll-up summary fields or sharing.
16
Q
Lookup relationships allow one object to be related to another in a one-to-many relationship. True or False?
A
True
17
Q
Lookup relationships can link one object with itself.
A
True
17
Q
Where is the related list added in a lookup relationship?
A
Related lists are added to the Lookup Object.
18
Q
Is Child access inherited from the parent?
A
No. Access to child records is independent from access to parent records.
19
Q
Standard report types are created for each lookup relationship. True or False?
A
True
20
Q
True or False? Once a lookup relationship is defined, a related list that shows the child records can be added to the page layout of the lookup object.
A
True
21
Q
A custom report type can be created if additional fields from the lookup object are required for the purpose of reporting. True or False?
A
True
22
Q
What is a Master Detail Relationship?
A
A master-detail relationship can be used to link two objects together closely.
23
Q
Is record security inherited in a master detail relationship?
A
Yes. The detail records inherit the sharing and security settings of the master record.
24
Deleting the master record automatically deletes the detail records in master detail relationships. True or False?
True
25
Can rollup summary fields be created in master detail relationships?
Yes. Roll-up summary fields can be created on the parent object to summarize the detail records.
26
A master-detail relationship field is always required on the detail records. Reparenting detail records can be enabled or disabled. True or False?
True
27
Each object can have up to two master-detail relationships, but standard objects cannot be on the detail side of a master-detail relationship when a custom object is on the master side. True or False?
True
28
Can you reparent records that are part of a master detail relationship?
By default, reparenting of records part of a master-detail relationship is not possible. However, administrators have the option to ‘Allow reparenting’ when creating the master-detail relationship which allows custom object child records to be reparented to different parent records.
29
What happens when a detail record in a master detail relationship is deleted?
If a detail record is deleted, the detail record will be moved to the Recycle Bin but the master record will remain. Undeleting a deleted detail record will restore that record.
30
What happens when a master record is deleted from a master detail relationship?
If a master record is deleted, the master and any detail records will be deleted and moved to the Recycle Bin. Undeleting a deleted master record will restore that record as well as any related detail records.
31
Fact - if a detail record is deleted and then the master record is deleted, undeleting the master record would restore the master record but not the detail record as they were not related at point of deletion.
32
How is sharing and security handled in a master detail relationship?
Detail and subdetail record permissions and security settings are inherited from the master record.
33
Owner fields in a master detail relationship are not available on detail and subdetail records, as they inherit the owner of the master record. True or False?
True
34
Custom objects on the detail side of a master-detail relationship are unable to use sharing rules, manual sharing or queues, as the Owner field is required. True or False?
True
35
Master-detail relationships allow data from three objects to be joined in one report: the master object, the detail object, plus one other lookup object. True or False?
True
36
How do you create a Junction Object?
A custom junction object is created with two master-detail relationships, each for one of the two objects that need to be linked together.
37
How is record access determined in a many to many relationship?
Access to a junction object record is determined by a user’s sharing access to both master records.
38
Roll-up summary fields can be created on both master objects to summarize data from the junction object. True or False?
True
39
How does deletion work in a many to many relationship?
Junction object records are deleted when either associated master record is deleted. If both master records are deleted, the junction object record is deleted permanently.
40
What is a Junction Object?
Junction objects are used to create many-to-many relationships. They sit between the two objects to be related. On the junction object, two master-detail relationship fields are created.
41
What does the read/write setting on two master records in a many to many relationship do?
If the sharing setting is ‘Read/Write’ on the two master records, then a user must have ‘Read/Write’ access to both master records to get ‘Read/Write’ access to the junction object records.
42
What does the read only setting on two master records in a many to many relationship do?
If the sharing setting is ‘Read Only’ on the two master records, then a user must have ‘Read Only’ access to both master records to get ‘Read’ access to the junction object records.
43
What are External Id's?
External IDs are fields that contain a unique identifier from a system outside of Salesforce.
44
What is the Unique Id Setting for on an external Id field?
External IDs are often created with the ‘Unique ID’ setting enabled so that External ID values are unique to each record inside Salesforce.
45
How many external Ids can be created on an object?
25
46
What are the valid field types for external Ids?
Text, email, number, auto-number.
47
Are External Ids Searchable?
Yes
48
Are External Ids Indexed?
Yes
49
What does an external lookup allow?
External lookup allows linking a child standard, custom or external object with a parent external object.
50
When would you use a lookup relationship?
When you need to effectively allow referencing data outside of the Salesforce organization.
51
The standard External ID field on the parent external object is matched against the values of the child’s external lookup relationship field. True or False?
True
52
What does an Indirect Lookup Allow?
Indirect lookup allows linking a child external object with a parent standard or custom object.
53
In an Indirect Lookup Relationship, how do we match and associate records?
A External Column Name and a unique External Id field are used for matching and associating the records.
54
How can we define a hierarchical relationship?
A hierarchical relationship can be defined on the User object to allow relating one user to another.
55
Creating a custom hierarchical relationship field is only allowed on the User object. True or False?
True
56
What are custom settings?
Custom settings enable application developers to create custom sets of data for an organization, profile, or specific user.
57
Can custom settings being queried?
Custom settings can be queried just like a custom object.

65
What is Schema Builder?
Schema Builder is a tool that can be used for creating and viewing the data model or customizing it according to requirements.
66
What viewing ability to does the schema builder provide?
It provides the ability to view the relationships and fields that are available for each object in Salesforce.
67
What elements can be added in schema builder?
Custom objects, master-detail relationships, lookup relationships, and custom fields except Geolocation can be added.
68
What is a limitation to adding custom fields via the schema builder?
Custom fields are not added automatically to page layouts. Custom field permissions are set to visible and editable for internal profiles only.
69
Can elements be hidden in the Schema Builder?
Yes, Objects and relationships that appear in the Schema Builder can be hidden to improve performance, but it is not possible to hide any fields.
70
What option can be used to manage permissions of a field in schema builder?
The ‘Manage Field Permissions’ option can be used to manage the permissions of a custom field for all standard and custom profiles.
