Salesforce Updated Integration-Architect Exam Questions and Answers by rumaysa

User Interface API should be used to implement this integration. User Interface API is a RESTful API that allows you to create native mobile apps and custom web apps with the look and feel of Salesforce’s Lightning Experience. User Interface API provides access to metadata, data, and UI components, such as layouts, actions, picklists, and record types. User Interface API also handles security, performance, and compatibility across different devices and browsers.

The integration architect should consider Change Data Capture Events and High Volume Platform Events for using the Streaming API with minimal data loss. Change Data Capture Events capture changes to Salesforce records and deliver them as events to subscribers. High Volume Platform Events are custom events that can be published and consumed at a large scale. Both types of events support reliable event delivery, which means that events are stored for 72 hours and can be replayed by subscribers in case of connection loss or failure. This ensures that data loss is minimized, even when the client re-connects every couple of days12

The end-to-end response time from the user’s perspective is the time elapsed between the user’s request and the user’s receipt of the final response. In the diagram, this corresponds to the sum of A and H, which are the durations of the synchronous calls from the user interface to the cloud-based application and back. The other durations (B to G) are either internal to the cloud-based application or asynchronous calls that do not affect the user’s perception of response time. Therefore, the correct answer is D, because it represents the sum of A and H.

Using an Enterprise Service Bus (ESB) to determine which shipping service to use, and transform requests to the necessary format is a good solution because it can provide routing, transformation, mediation, and orchestration capabilities for integrating different services. An ESB can also abstract the complexity and heterogeneity of the services from the client application, which simplifies the integration. Using Outbound Messaging to request costs and delivery times from Shipper delivery services with automated error retry is not a good solution because Outbound Messaging is a Salesforce-specific feature that uses SOAP web services, which may not be compatible with all shipping services. Using APEX REST Service to implement routing logic to the various shipping service is also not a good solution because it can introduce performance and scalability issues, as well as increase the maintenance cost and complexity of the code. Using Enterprise Service Bus user interface to collect shipper-specific form data is not a valid option because an ESB does not have a user interface component.
