DreamHouse Realty (DR) is expanding into subsidized housing by partnering with local government entities.

The correct answers are A. Data loss may occur when changing custom field types and D. Field History Tracking records value changes of 255 characters or less.

A is correct because Salesforce warns that changing the data type of an existing custom field can cause data loss in certain situations. This is a key consideration before converting Text Area (Long) fields to Rich Text Area fields.

D is correct because Salesforce field history tracking has a character limitation. Salesforce tracks changes to fields with more than 255 characters as edited, but it does not record the old and new values. That means long/rich text changes beyond that limit do not provide full before-and-after history values.

Why others are incorrect:

B is not the relevant consideration for this field conversion requirement.

C is incorrect because Salesforce reports do not display rich text field values of all lengths fully; Salesforce documentation notes report display limits for long text and rich text area fields.
