Which two considerations should be made by the team?

DreamHouseRealty (DR) is expanding into subsidized housing by partnering with local government entitles. DR uses Sales Cloud and has enabled field history tracking on the Opportunity object. Due to increased Information requirements, the App Dev team is changing Text Area (Long) fields to Rich Text fields to allow for up to 1,000 characters and better descriptions.

Which two considerations should be made by the team? Choose 2 answers
A . Rich text field values of all lengths are displayed fully in reports.
B . Data loss may occur when changing custom field types.
C . Field History Tracking records value changes of 255 characters or less.
D . Audit Trail is available through REST API extracts.

Answer: B, C

Explanation:

Changing custom field types may result in data loss if the new field type is incompatible with the old one. For example, changing a text field to a number field may cause text values to be deleted. Field history tracking records value changes of 255 characters or less. If a rich text field value exceeds this limit, only the first 255 characters are tracked.
