NEW QUESTION # 83
Northern Trail Outfitters (NTO) is planning to create a native employee-facing mobile app with the look and feel of Salesforce Lighting Experience. The mobile app needs to integrate with NTO's Salesforce org. Which Salesforce API should be used to implement this integration?
Answer: C
Explanation:
When building custom mobile or web applications that aim to replicate the look and feel of Salesforce Lightning Experience, the User Interface (UI) API is the architecturally recommended choice.
The UI API is specifically designed to provide the metadata and data needed to build high-fidelity user interfaces. Unlike the standard REST API (Option B), which returns raw record data, the UI API returns both data and metadata in a single response. This includes information about page layouts, field-level security, picklist values, and localized labels. By using the UI API, the mobile app can dynamically render fields according to the user's permissions and the organization's layout configurations, ensuring that the custom app stays in sync with changes made in Salesforce Setup without requiring code updates in the mobile app.
Connect REST API (Option A) is primarily used for Chatter, Communities (Experience Cloud), and CMS content, and while it is useful for those specific social features, it does not provide the layout and record-level metadata required for a full CRM interface. The UI API is the same underlying technology that powers the Salesforce mobile app and Lightning Experience itself. Therefore, utilizing this API allows NTO's developers to build a native app that perfectly mimics the Lightning Experience while reducing the amount of custom logic needed to handle complex Salesforce UI requirements.
NEW QUESTION # 84
Northern Trail Outfitters needs to make synchronous callouts to "available-to-promise" services to query product availability and reserve inventory during the customer checkout process. What should an integration architect consider when building a scalable integration solution?
Answer: A
NEW QUESTION # 85
Northern Trail Outfitters has had an increase in requests from other business units to integrate opportunity information with other systems from Salesforce. The developers have started writing asynchronous @future callouts directly into the target systems. The CIO is concerned about the viability of this approach and scaling for future growth. What should be done to mitigate the CIO's concerns?
Answer: A
Explanation:
The CIO's concern regarding "viability" and "scaling" is rooted in the risks associated with tightly coupled, point-to-point integrations. Using @future methods for direct callouts creates a "spaghetti" architecture where Salesforce must manage the specific endpoints, authentication, and error logic for every external system.
The architect should recommend implementing an Enterprise Service Bus (ESB). An ESB acts as a centralized middleware layer that provides mediation, routing, and orchestration. By moving the integration logic to an ESB, Salesforce only needs to send a single message to the bus. The ESB then takes responsibility for delivering that data to multiple business units and external systems. This decouples Salesforce from the downstream systems; if a target system changes its API or is replaced, only the ESB configuration needs to be updated, not the Salesforce Apex code.
While External Services (Option A) provide a low-code way to call APIs, they still represent point-to-point connections and do not solve the broader orchestration and scaling challenges. ETL tools (Option C) are designed for bulk data movement and would not satisfy the need for the near real-time updates that the existing callout logic likely supports. An ESB provides the "quality of service" features-such as guaranteed delivery, retries, and protocol transformation-that are necessary for a growing enterprise to maintain a stable and scalable integration landscape.
NEW QUESTION # 86
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.
NEW QUESTION # 87
Northern Trail Outfitters submits orders to a manufacturing system web service that has experienced multi-day outages. Which solution should an integration architect recommend to handle errors during these types of outages?
Answer: C
Explanation:
When a target system experiences prolonged outages (lasting "several days"), point-to-point integration solutions built within Salesforce are likely to fail or reach their retry limits. For example, Salesforce Outbound Messaging (Option B) only retries for up to 24 hours before dropping the message.
The architecturally robust solution is to introduce a Middleware layer (ESB or iPaaS) that provides queuing and buffering. In this model, Salesforce sends the order to the middleware. The middleware immediately acknowledges receipt (preserving Salesforce performance). If the manufacturing system is offline, the middleware stores the message in a persistent queue.
Middleware is designed for this high level of Quality of Service (QoS). It can be configured with custom retry logic-such as waiting 30 minutes between attempts-and can hold millions of messages for days or even weeks. This effectively "insulates" Salesforce from the manufacturing system's instability. Option C is overly complex and requires custom development in both the event bus and Apex, whereas middleware provides this functionality as a native capability. By using middleware, the architect ensures that no orders are lost during extended manufacturing downtime and that the integration is decoupled and resilient.
