Free Practice Questions for Salesforce Integration-Architect Exam

Middleware should coordinate request delivery and payment processing, and Payment System should process a payment request only once. This solution ensures that each payment request is delivered to the Payment System in a reliable and consistent manner,and avoids duplicate or conflicting updates to the same Payment Request record. Middleware can act as a mediator between the Data Entry Point and the Payment System, and implement logic to handle errors, retries, and acknowledgments. Payment System can usethe globally unique identifier to check if a payment request has already been processed, and avoid processing it again.

The Data Virtualization pattern allows Salesforce to access external data sources without storing the data in Salesforce. This reduces the data storage and synchronization costs and enables real-time access to the historical data. Salesforce Connect can be used to consume OData endpoints exposed by the ESB tool and display the external objects as related lists or custom components on the Case object

 These are three considerations that an Integration Architect should consider when recommending Platform Event as an Integration solution. Platform Events are a type of event-driven architecture thatallows you to publish and subscribe to custom events in Salesforce and external systems. Platform Events have some limitations and features that an Integration Architect should be aware of, such as:

Inability to query event messages using SOQL. Platform Events are not stored in Salesforce database, but in an event bus that retains them for 24 hours. You cannot use SOQL to query event messages, but you can use the EventLogFile object or the Event Monitoring feature to access them.

Inability to create a Lightning record page for platform events. Platform Events are not standard or custom objects, but a special type of sObject that can be inserted into the event bus. You cannot create a Lightning record page for platform events, but you can use Apex triggers, Lightning web components, or CometD clients to subscribe to them.

When you delete an event definition, it’s permanently removed and can’t be restored. An event definition is a metadata type that defines the schema and properties of a platform event message.You can create or modify event definitions in Salesforce Setup or using Metadata API. However, if you delete an event definition, it’s permanently removed from your org and can’t be restored. You also lose access to any event messages that use that eventdefinition.

UseSalesforce Connect if the database supports Open Data Protocol (OData). Salesforce Connect allows you to integrate external data sources with Salesforce without copying the data into Salesforce. OData is a standard protocol for accessing data from different sources. Use Salesforce Connect if the database supports Open Database Connectivity (ODBC) is incorrect because ODBC is not supported by Salesforce Connect. Use Heroku Connect if the data is hosted in Heroku is incorrect because Heroku Connect is used to synchronize data between Salesforce and a Heroku Postgres database, not an on-premises system.

The Fire and Forget pattern is suitable for this business use case because it allows sending a message from Salesforceto the remote system without waiting for a response or acknowledgement. This reduces the latency and complexity of the integration and enables asynchronous processing of the orders in the remote system. The platform event defined in Salesforce can be used to publish the order details to the remote system, which can subscribe to the event and create the order accordingly1

The integration consultant should evaluate current and future data and system usage andthen identify potential integration requirements to Salesforce. This approach can help to understand the business needs, data flows, data quality, data volume, data frequency, and data security of the proposed CRM system. Based on this analysis, the integration consultant can design and implement the best integration solution for each system, such as Marketing, ERP, or Outlook.

Trigger invokes Queueable Apex method, with custom error handling process. Queueable Apex allows you to run asynchronous jobs that can make callouts to external web services. You can use custom error handling logic to handle any failures and retry the callouts if necessary. You can also use Database.Stateful interface to maintain state across transactions and ensure that each order is sent exactly once. This solution meets the requirements of sending order and line items directly to an existing finance application web service when an order is fulfilled, and ensuring that each order reaches the finance application exactly once for accurate invoicing.

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 correct answer is A, C, and D. These are three relevant details that a Salesforce Integration Architect should seek to specifically solve for Integration architecture needs of the program. These detailscan help the Integration Architect to understand the scope, requirements, and constraints of the integration solution, and to choose the appropriate tools, methods, and patterns. The details are:

Source and Target system, Directionality, data volume & transformation complexity along with any middleware that can be leveraged. This detail can help theIntegration Architect to identify the systems involved in the integration, the direction of data flow, the amount and complexity of data to be exchanged, and the middleware or platform capabilities that can facilitate the integration.

Timing aspects - real-time/near real-time (synchronous or asynchronous), batch; update frequency. This detail can help the Integration Architect to determine the latency, reliability, and scalability requirements of the integration solution, and to choose the suitable integration protocols and techniques.

Integration Style - Process based, Data based, Virtual integration. This detail can help the Integration Architect to select the appropriate integration style that matches the business needs and objectives. Process based integration focuses on orchestrating business processes across systems, data based integration focuses on synchronizing data across systems, and virtual integration focuses on providing a unified view of data across systems.

Handle verification process error in the Verification Webservice API in case there is a connection issue to the Webservice or if it responds with an error. This solution ensures that the agent can see an error message when the credit verification process failed, and take appropriate actions. The Verification Webservice API can implementerror handling logic to catch anyexceptions or errors that occur during the callout to the external agencies, and return a meaningful error message to the agent. The agent can then retry the verification process, or escalate the issue to a supervisor. References: Certification - Integration Architect - Trailhead, [Apex Web Services and Callouts]
