   A business requires a solution that can scale to handle unpredictable spikes in user demand. How might incorporating an external application affect the scalability of the overall architecture?

   • AIt guarantees that the entire solution will scale automatically without any additional design effort
   • BIt eliminates the need to consider scalability because the external application handles everything
   • CIt may offload scalability concerns to the vendor, but the integration layer must also be designed to handle the load
   • DIt reduces scalability because external applications are always less scalable than custom code

   A global logistics company is evaluating a third-party route optimization service that will be called from Salesforce to calculate delivery routes. The service is known for excellent algorithms but has a variable response time, sometimes exceeding 10 seconds. The company's dispatchers need route suggestions within 2 seconds to maintain operational efficiency. What should the solution architect recommend?

   • AIntegrate the service synchronously via API, accepting the variable response time.
   • BCall the external service only during off-peak hours to avoid slow responses.
   • CUse a middleware layer that caches route results and asynchronously updates them, providing fast responses from cache.
   • DBuild a custom route optimization algorithm in-house to ensure consistent performance.

   A healthcare organization wants to integrate a third-party patient portal with Salesforce. The portal needs to display appointment information and allow patients to update their contact details. The organization requires real-time data synchronization to ensure patients see the most current information. Which integration pattern should the solution architect recommend?

   • BBatch data synchronization nightly using a middleware tool.
   • CFile-based data exchange via SFTP on a scheduled basis.
   • DAPI-based integration where the portal calls Salesforce APIs in real time to fetch and update data.
