NEW QUESTION # 105
A customer's enterprise architect has identified requirements around caching, queuing, error handling, alerts, retries, event handling, etc. The company has asked the integration architect to help fulfill such aspects with its Salesforce program. Which recommendation should the integration architect make?
Answer: C
Explanation:
Salesforce is a highly capable CRM platform, but it is not a dedicated messaging or orchestration engine. When requirements include complex message queuing, process choreography, and guaranteed quality of service (QoS), the Integration Architect must recommend a middleware solution (ESB or iPaaS).
"True message queuing" involves holding messages in a persistent state until the target system is ready to receive them, handling sophisticated retry logic (such as exponential backoff), and providing dead-letter queues for failed messages. While Salesforce has basic asynchronous tools like Outbound Messaging or Platform Events, they lack the granular control over queuing and orchestration that enterprise middleware provides.
Option A is incorrect because performing heavy transformation and protocol translation (like XML to JSON or SOAP to REST) within Salesforce consumes excessive Apex CPU time and is better handled by middleware designed for that purpose. Option B is conceptually backward; usually, architects move away from synchronous Request-Reply toward asynchronous Fire-and-Forget to improve scalability. By recommending a middleware solution to handle these infrastructure-level concerns, the architect ensures that Salesforce remains performant for its users while the middleware manages the technical complexities of reliably connecting the enterprise.
NEW QUESTION # 106
A business requires automating the check and updating of the phone number type classification for all incoming calls. Up to 100,000 calls per day are received, and the business is flexible with timing (every 6-12 hours is sufficient). A Remote-Call-In and/or Batch Synchronization pattern via middleware is planned. Which component should an integration architect recommend to implement these patterns?
Answer: A
Explanation:
In a Remote-Call-In or Batch Synchronization pattern where an external middleware initiates the connection to Salesforce, the external system must be authenticated. The standard Salesforce framework for this is the Connected App.
A Connected App provides a framework for external applications to integrate with Salesforce using APIs and standard protocols like OAuth 2.0. For a high-volume (100,000 records) batch process initiated by middleware every 6-12 hours, the architect would recommend a Connected App using a secure flow, such as the OAuth 2.0 JWT Bearer Flow. This allows the middleware to authenticate as a specific "Integration User" without storing clear-text passwords.
Option A (API Gateway) is used to manage and secure outbound calls from Salesforce or between external services; it does not handle inbound authentication to the Salesforce org itself. Option B (Remote Site Settings) is a whitelist configuration used purely to allow Salesforce to make outbound callouts to a specific URL; it provides no authentication mechanism for systems calling into Salesforce. By recommending a Connected App, the architect ensures that the middleware has the necessary permissions (scopes) to use the Bulk API-which is the appropriate mechanism for the 100,000 record volume-while maintaining a secure, auditable, and standard integration boundary.
NEW QUESTION # 107
A new Salesforce program has the following high-level abstract requirement: Business processes executed on Salesforce require data updates between their internal systems and Salesforce. Which relevant detail should an integration architect seek to specifically solve for integration architecture needs of the program?
Answer: B
Explanation:
In the discovery and translation phase of a Salesforce project, an Integration Architect must move beyond high-level business goals to define the technical "DNA" of the data exchange. While organizational readiness and user experience are vital to project success, they do not dictate the architectural patterns required to move data between systems.
The most critical details for designing an integration architecture are the Timing and Volume requirements. Identifying whether a business process is Synchronous or Asynchronous is the primary decision point. For example, if a Salesforce user requires an immediate validation from an external system before they can save a record, a synchronous "Request-Reply" pattern using an Apex Callout is required. If the data update can happen in the background without blocking the user, an asynchronous "Fire-and-Forget" pattern is preferred to improve system performance and user experience.
Furthermore, understanding the Update Frequency (e.g., real-time, hourly, or nightly) and the Data Volume (e.g., 100 records vs. 1 million records) allows the architect to select the appropriate Salesforce API. High-volume, low-frequency updates are best handled by the Bulk API to minimize API limit consumption, while low-volume, high-frequency updates are better suited for the REST API or Streaming API. By specifically seeking out these timing and frequency aspects, the architect ensures that the chosen solution is scalable, stays within platform governor limits, and meets the business's Service Level Agreements (SLAs). Without these details, the architect risks designing a solution that is either too slow for the business needs or too taxing on system resources.
NEW QUESTION # 108
When a user clicks "Check Preferences" as part of a Lightning flow, preferences from an externally hosted RESTful service are to be checked in real time. The service has OpenAPI 2.0 definitions. Which integration pattern and mechanism should be selected?
Answer: C
Explanation:
This scenario describes a classic Request and Reply pattern where a user action in the UI requires an immediate, synchronous response from an external system to determine the next step in a business process (the Flow).
The requirement specifies that an OpenAPI 2.0 (Swagger) definition is available. For an Integration Architect, this is a prime use case for External Services. External Services allow you to import an OpenAPI schema and automatically generate "Invocable Actions" that can be used directly in Flow Builder without writing a single line of Apex code.
Why this is the best fit:
Low Code: It fulfills the requirement purely through declarative configuration, which reduces maintenance and development costs.
Real-Time: It performs a synchronous HTTP callout and waits for the Boolean/String values to be returned to the Flow variables.
Type Safety: Because it uses the OpenAPI definition, Salesforce understands the data types (Boolean/String) natively.
Option A (Data Virtualization) is more suitable for viewing and searching large external datasets as if they were records; it is over-engineered for a simple "check status" function. Option C (Remote Call-In) is the inverse of the requirement; it refers to an external system calling into Salesforce. By using Enhanced External Services, the architect provides a scalable, declarative solution that perfectly aligns with modern Salesforce development best practices for real-time external system interaction.
NEW QUESTION # 109
An integration architect has designed a mobile application for Salesforce users to get data while on the road using a custom user interface (UI). The application is secured with OAuth and is currently functioning well. There is a new requirement where the mobile application needs to obtain the GPS coordinates and store them on a custom geolocation field. The geolocation field is secured with field-level security, so users can view the value without changing it. What should be don4e to meet the requirement?
Answer: C
Explanation:
When a custom mobile application already secured with OAuth needs to update a record in Salesforce, the standard architectural recommendation is to use the REST API. The REST API is optimized for mobile environments because it uses lightweight JSON payloads and follows standard HTTP methods (such as PATCH for updates), which are highly compatible with mobile development frameworks.
In this specific scenario, the architect must address the Field-Level Security (FLS) constraint. Because the geolocation field is set to read-only for users, a standard UI-based update would typically fail. However, when using an inbound REST API call with a properly authorized integration user or via a "System Mode" context (if utilizing a custom Apex REST resource), the system can be configured to bypass UI-level restrictions while maintaining data integrity.
The mobile device captures the coordinates via the device's native GPS capabilities and initiates an inbound call to the Salesforce REST endpoint. Option A (Apex inbound call) is a subset of REST functionality but is only necessary if complex server-side logic is required that the standard REST API cannot handle. Option C is technically incorrect as mobile devices do not typically "receive" callouts from Salesforce in this pattern; they initiate the requests. By leveraging the standard REST API, the architect ensures a scalable, secure, and standardized integration that adheres to Salesforce's mobile-first integration principles.
