• B. Single-use, disposable resources
• C. Hierarchical organization of related content
• D. Random access to unrelated content

How does a C4E differ from a Center of Excellence (CoE)?

• A. C4E decentralizes enablement, while CoE centralizes expertise.
• B. C4E focuses more on governance, while CoE focuses on innovation.
• C. C4E is less about providing support and more about enforcing policies.
• D. There is no difference; they are just different terms for the same concept.

An architect is designing APIs to be used by e-commerce channels. The current design for the Shopping Cart API has a direct query to the inventory system's data store to check for available inventory before an item can be added to the cart. The inventory system has recently been updated and has sufficient capacity to respond to predicted volumes of inventory queries in a timely manner.
The Shopping Cart API is not the only application that interacts with the inventory system. The architect is aware that the inventory system also broadcasts inventory update messages to the enterprise messaging system (available via a JMS topic).
What pragmatic design change can be made to make the Shopping Cart API more composable?

• A. Add an Inventory System API to the design to encapsulate all inventory queries, replace the direct query to the inventory data source from the Shopping Cart API with a call to the Inventory System API instead
• B. Subscribe to receive inventory update messages (from the JMS topic) and maintain in-memory inventory levels in the Shopping Cart API so that queries to the external inventory system can be completely removed from the design
• C. Add in-memory caching to the inventory lookup in the Shopping Cart API implementation to reduce queries to the backend inventory system and improve response times for the Shopping Cart API
• D. Add an Inventory Update Notification API that consumes inventory update messages from the JMS topic and updates an in-memory cache of inventory levels that is stored in a new Inventory System API; update the Shopping Cart API to query the Inventory System API for all inventory queries

Which principles of architecting with Catalyst are valuable for projects and engagements?
