For automatically updating contact statuses when an account type changes:
* D. Record triggered flow. This type of automation can monitor changes in account types and accordingly update related records, such as contacts.
Steps to implement:
* Navigate to Setup # Flows.
* Create a new Flow and choose the record-triggered flow type.
* Configure the flow to trigger when the Account record is updated to 'Past-Customer'.
* Add an Update Records element to modify all related contacts, setting their status to 'Re-Market'.
* Activate the flow.
This automation ensures that contact statuses are updated in real-time when their related account's type changes, maintaining data consistency and relevancy.

One of the limitations when using the Schema Builder for creating fields is:
* C. Cannot add fields to page layouts. While Schema Builder allows for easy visualization and creation of fields and objects, it does not support placing these fields onto specific page layouts directly from the Schema Builder interface.
To place fields on page layouts, you need to:
* Navigate to Setup # Object Manager # select your object.
* Click on Page Layouts, choose the appropriate layout, and manually add the newly created fields.
This step is necessary to ensure fields are visible and properly arranged on user interfaces.
