   Which statement accurately describes a trade-off of the Remote Process Invocation—Request and Reply pattern?

   • AIt is best suited for high-volume data transfers where immediate response is not required.
   • BIt eliminates the need for error handling because the caller always receives a successful response.
   • CIt allows the caller to continue processing without waiting, improving throughput at the cost of error visibility.
   • DIt provides immediate feedback to the caller but can increase latency and coupling between systems.

   Which statement correctly describes a trade-off of the Remote Process Invocation—Fire and Forget pattern?

   • AIt reduces coupling because the caller and receiver are fully decoupled and never interact.
   • BIt improves throughput by not blocking the caller, but error handling and state consistency become more challenging.
   • CIt guarantees exactly-once processing, ensuring state consistency at all times.
   • DIt is best used when a response is required to continue business logic.

   Which statement correctly describes a trade-off of the Remote Call-In pattern?

   • AIt is best for high-volume data transfers because it uses batch processing.
   • BIt eliminates the need for authentication because the call originates from a trusted external system.
   • CIt provides real-time data access but introduces security risks and scalability challenges.
   • DIt reduces network usage by sending data only when changes occur.

   A healthcare provider wants to allow its external partner to query patient appointment availability in Salesforce in real time. The partner will make occasional, low-volume requests. Security is a top concern, and the provider wants to avoid exposing Salesforce directly to the internet. Which pattern should the architect recommend?

   • AUse a platform event to publish appointment availability changes to the partner.
   • BUse a middleware platform to receive the partner's request, authenticate, and then call Salesforce via a private API.
   • CExpose a custom REST API in Salesforce and allow the partner to call it directly over the internet.
   • DUse a batch synchronization to replicate appointment data to the partner's system nightly.

   A university wants to allow students to check their grades in real time via a mobile app. The grades are stored in Salesforce. The university wants to avoid building a custom API and prefers a solution that is easy to maintain. Which pattern should the architect recommend?

   • AUse a platform event to push grades to the mobile app.
   • BUse a batch synchronization to export grades to a public database.
   • CUse Salesforce REST API with OAuth 2.0 for the mobile app.
