Explanation
The consultant should design the FlexCards as follows to meet the requirements:
Parent FlexCard with multiple Child Flex Cards and Card Actions. A Parent FlexCard is a construct in Financial Services Cloud that allows you to display information from one record in a card-like format on a Lightning page. A Child FlexCard is a construct in Financial Services Cloud that allows you to display information from related records in a card-like format within a Parent FlexCard. A Card Action is a construct in Financial Services Cloud that allows you to perform actions on a record from within a FlexCard, such as edit, delete, renew, or view details. You can use Parent FlexCards, Child FlexCards, and Card Actions to create an agent console that provides a 360-degree view of your customers and enables quick actions on their records.
