App Builder Platform-App-Builder Salesforce Study Notes

Schema Builder is a tool that allows app builders to view and modify the data model of their Salesforce org. Some of the capabilities of Schema Builder are:

Creating and editing custom objects and fields

Creating and editing relationships between objects

Showing selected objects on a page

Editing custom settings

Schema Builder cannot be used to create a new record type or view page layouts in a new window.

AppExchange is a marketplace where app builders can find prebuilt resources to help with migration and adoption projects. AppExchange offers apps, components, solutions, and consulting services that can assist with moving from Classic to Lightning Experience. Import Wizard, Lightning Object Creator, and Flow Builder are not sources of prebuilt resources, but tools for data import, object creation, and automation respectively.

The requirement specifies:

Subset of production data (not all data)

Under 5 GB of data

Periodic refresh (every weekend)

A Partial Copy sandbox fits these requirements perfectly — it includes sample data defined by a sandbox template, up to 5 GB, and has a refresh interval of 5 days (the shortest interval available besides Developer types).

Why A (Partial Copy) is correct:Exact Extract:“A Partial Copy sandbox includes your organization’s metadata and a sample of your production data as defined by a sandbox template. The maximum size is 5 GB and the refresh interval is 5 days.” — Salesforce Help | Sandbox Types and Templates

Why not B (Full Copy):Full Copy includes all production data and has a 29-day refresh interval.

Why not C or D:Developer and Developer Pro sandboxes contain metadata only and no production data.

The validation rule should be AND(ISNEW(), ISBLANK(Lead.Owner:User.Id)). This rule will prevent saving a new lead record if the owner is not a user. This will ensure that campaign members have a sales owner. Option A is incorrect because it will prevent saving any lead record if the owner is blank, which is not the requirement. Option B is incorrect because it will prevent saving an existing lead record if the owner is a queue, which is not the requirement. Option D is incorrect because it will prevent saving any lead record if the owner is a queue, which is not the requirement.
