Salesforce Certified Platform Integration Architect Sample Questions (Q78-Q83):
NEW QUESTION # 78
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: A
Explanation:
When an enterprise architect identifies infrastructure-level requirements such as caching, queuing, and complex event handling, it signals a need for a dedicated integration layer. Salesforce is an engagement platform, not a dedicated message broker or Enterprise Service Bus (ESB). For complex event handling in a publish/subscribe scenario, the architect should recommend leveraging middleware to act as the central nervous system of the integration landscape.
The middleware provides a robust environment to manage the lifecycle of a message. It can receive a single event from a publisher (like Salesforce via Platform Events) and then route that message to multiple active subscribers. This decoupling ensures that Salesforce doesn't need to manage the connection state or retry logic for every downstream system. Middleware tools are specifically designed to handle "Quality of Service" (QoS) requirements like guaranteed delivery, message sequencing, and dead-letter queuing, which are difficult to manage natively at scale within Salesforce limits.
Option A is incorrect because shifting from Fire-and-Forget to Request-Reply generally decreases performance and scalability due to the synchronous nature of the wait time. Option C is also incorrect; protocol translation (e.g., SOAP to REST) and heavy message transformation are exactly what middleware tools are built for. By performing these tasks in middleware, you conserve Salesforce's Apex CPU limits and maintain a cleaner, more maintainable CRM environment. Therefore, using middleware for routing and event handling is the standard architectural recommendation for a mature enterprise program.
NEW QUESTION # 79
A company captures orders and needs to send them to the Order fulfillment system. The user is not required to have confirmation from the fulfillment system. Which system constraint question should be considered when designing this integration?
Answer: A
Explanation:
When a business process does not require immediate confirmation from a target system, the architecture can move from a synchronous Request-Reply pattern to an asynchronous Fire-and-Forget pattern. In this transition, the most critical "non-functional" requirement for the Integration Architect is to define acceptable latency.
Latency determines the technical stack. If the fulfillment system must receive the order within seconds (Near Real-Time), the architect might choose Salesforce Outbound Messaging or a Flow-triggered Platform Event. If the order only needs to arrive within 4-12 hours, a Batch ETL process is more efficient as it conserves API limits and can handle much higher volumes more reliably.
While address validation (Option B) is a functional requirement, it does not define the architectural framework. Option C is a specific solution implementation question rather than a fundamental design constraint. By asking about latency, the architect identifies the time boundary between "Data Entry" in Salesforce and "Processing" in the fulfillment system. This answer directly informs the choice of pattern, the retry logic required, and the error-handling strategy needed to ensure the "Order-to-Cash" cycle is completed successfully without blocking the sales rep's productivity.
NEW QUESTION # 80
Northern Trail Outfitters needs to present shipping costs and estimated delivery times to its customers. Shipping services used vary by region and have similar but distinct service request parameters. Which integration component capability should be used?
Answer: A
Explanation:
When dealing with multiple external service providers (like different regional shippers) that have varying API requirements, the most scalable architectural choice is an Enterprise Service Bus (ESB) or middleware solution. This scenario describes a classic "Orchestration" and "Transformation" use case.
An ESB excels at:
1. Routing/Mediation: The ESB can receive a single, standardized request from Salesforce ("Get Shipping Rates") and use business logic to determine which regional carrier's API should be called.
2. Transformation: Each carrier likely has a distinct XML or JSON schema. The ESB can transform the common data model sent by Salesforce into the specific format required by the chosen shipper.
3. Protocol Bridging: If one shipper uses SOAP and another uses REST, the ESB handles these technical differences, allowing Salesforce to interact with a single, simplified interface.
Option A (Apex REST) would require the Salesforce team to maintain custom code for every new shipping provider added, leading to high technical debt and maintenance challenges. Option C is incorrect because an ESB is a back-end infrastructure component, not a user interface tool.
By utilizing an ESB, Northern Trail Outfitters decouples Salesforce from the complexities of the shipping providers' APIs. This "Hub and Spoke" model means that adding a new regional shipper in the future only requires configuration within the ESB, rather than a full code deployment in Salesforce. This provides the agility and architectural separation necessary for a global retail operation.
NEW QUESTION # 81
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 # 82
Northern Trail Outfitters leverages Sales Cloud. When an opportunity has changed its status to "Closed/Won" and there are products attached, the details should be passed to the OMS for fulfillment operations. The callout from Salesforce to the OMS should be synchronous. What should an integration architect do to satisfy these requirements?
Answer: A
Explanation:
A synchronous requirement in Salesforce implies a Request-Reply pattern where the user waits for a response. To implement this correctly while adhering to platform constraints, the architect must initiate the callout from the User Interface (UI) layer.3 Option C is the correct architectural choice. By using a Lightning component and a button (or a Quick Act4ion), the callout is initiated directly from the user's session. The component calls an Apex controller, which performs the synchronous REST callout to the OMS. This allows the user to receive immediate feedback-such as a "Success" message or an "Error" notification from the OMS-directly on the Opportunity page.
Option A is incorrect because Apex Triggers are prohibited from making synchronous callouts. If a trigger initiates a callout, it must be asynchronous (using @future or Queueable Apex), which violates the business requirement for synchronicity. Making a synchronous call from a trigger would block the database transaction and could lead to "Uncommitted Work Pending" errors or system timeouts. Option B (Batch Apex) is inherently asynchronous and delayed; an hourly job would not provide the real-time, synchronous feedback required during the "Closed/Won" transition. Therefore, moving the integration logic to a UI-driven button is the only way to satisfy the synchronous requirement while staying within Salesforce's execution and transaction limits.
