How can you ensure that changes to a card will be updated across all layouts using that card?

• A. Create a new version of the card
• B. Test the layouts with the updated card
• C. Clone the card and select layouts
• D. Create a public version using the XML interface

Answer: (A)

Creating a new version of the card is the correct approach to ensure that any changes made will be reflected across all layouts that utilize that card. In the Vlocity platform, cards are reusable components, and when you create a new version, it allows the system to manage updates in a way that maintains consistency. All instances of the card across various layouts will automatically use the updated version, thus guaranteeing that the latest changes are presented uniformly.

In contrast, the other options don't effectively accomplish the goal of ensuring uniform updates across all layouts. While testing the layouts with the updated card might help to identify issues, it does not facilitate automatic updates without manually adjusting each layout. Cloning the card and selecting layouts could lead to the creation of multiple versions, which may complicate maintenance rather than streamline it. Lastly, creating a public version using the XML interface might provide options for sharing or accessing the card, but it does not inherently ensure that all layouts will reflect any changes made to the card. Therefore, maintaining a single, updated version through versioning is the most effective strategy.
