質問 # 114
A company that is a leading provider of courses and training delivers courses using third-party trainers. The trainer for the company has to be verified by 10 different training accreditation verification agencies before providing training for the company. Each training accreditation agency has its own response time, which means it could take days to confirm a trainer. The company decided to automate the trainer accreditation verification process by integrating it with the agency's web service1s. What is the recommended approach to automa2te this process?3456
正解：B
解説：
In this scenario, the primary architectural challenge is managing high-latency, multi-step orchestration involving 10 disparate external systems. Each agency has a varying response time that can span several days, making a synchronous "Request-Reply" pattern within Salesforce technically impossible due to transaction timeout limits (maximum 120 seconds).
The recommended approach is to leverage Middleware as the orchestration and state-management layer. Middleware (such as an ESB or iPaaS) is specifically designed for Process Choreography. Salesforce initiates a single "Fire and Forget" request to the middleware. The middleware then takes responsibility for:
Sequential or Parallel Callouts: Initiating the requests to all 10 verification agencies.
Callback Management: Handling the asynchronous responses from each agency as they arrive over a period of days.
Aggregation Logic: Consolidating the results and determining when the "Business Process" is complete (e.g., all 10 agencies have approved).
Once the consolidation logic is satisfied, the middleware performs a Remote Call-In to the Salesforce REST API to update the trainer's record. This pattern keeps Salesforce "clean" by moving complex, long-running orchestration logic off-platform, preventing the consumption of excessive Apex CPU time and ensuring that Salesforce only receives a single, final status update.
Option B (External Services) is unsuitable for a multi-day asynchronous process as it is designed for real-time, synchronous Flow actions. Option C (@future) is restricted by the same 120-second timeout and cannot handle the "waiting" state required for days of verification. Using middleware provides the necessary Quality of Service (QoS), durability, and error handling required for such a critical enterprise compliance process.
質問 # 115
An enterprise architect has requested the Salesforce integration architect to review the following (see diagram and description) and provide recommendations after carefully considering all constraints of the enterprise systems and Salesforce Platform limits.
About 3,000 phone sales agents use a Salesforce Lightning user interface (UI) concurrently to check eligibility of a customer for a qualifying offer.
There are multiple eligibility systems that provide this service and are hosted externally.
However, their current response times could take up to 90 seconds to process and return (there are discussions to reduce the response times in the future, but no commitments are made).
These eligibility systems can be accessed through APIs orchestrated via ESB (MuleSoft).
All requests from Salesforce will have to traverse through the customer's API Gateway layer, and the API Gateway imposes a constraint of timing out requests after 9 seconds.
Which recommendation should the integration architect make?
正解：B
解説：
The primary architectural challenge in this scenario is the massive discrepancy between the backend response time (up to 90 seconds) and the API Gateway timeout constraint (9 seconds). In any synchronous integration pattern, the connection must remain open across the entire path; if the API Gateway closes the connection at 9 seconds, a standard Salesforce "Request-Reply" callout will fail long before the 90-second eligibility check is complete.
Option A is non-viable because synchronous polling at a high scale (3,000 concurrent users) would likely hit Salesforce concurrent request limits and place an immense, unnecessary load on the API Gateway. Option B, using Continuation, is designed to handle long-running callouts (up to 120 seconds) without blocking Salesforce threads, but it still requires the external connection path to remain open. It does not bypass the 9-second timeout imposed by the customer's API Gateway.
The optimal recommendation is Option C, which implements an Asynchronous Request-Reply pattern using Platform Events and the empAPI.12 Request Phase: The Salesforce UI initiates the request. To bypass the 9-second gateway timeout, the ESB (MuleSoft) should be configured to receive the request3 and immediately return an acknowledgment (e.g.,4 HTTP 202 Accepted). This allows the initial Salesforce callout to complete successfully within the 9-second window.56 Processing Phase: MuleSoft then proceeds with the long-running (up to 90 seconds) call to the external eligibility systems.78 Callback Phase (Remote Call-In)9: Once the eligibility result is received, MuleSoft calls back into Salesforce via the REST API to publish a Platform Event containing the result.10 UI Update (empA11PI): The 3,000 sales agents' browsers, having subscribed to the event channel using the empAPI (Lightning's built-in library for streaming events), receive the notification in real-time. The UI then updates to display the "Display Response" step.
This event-driven architecture effectively "insulates" Salesforce and the API Gateway from the backend's high latency, ensures scalability for 3,000 concurrent users, and provides a seamless, real-time user experience without hitting governor limits or timeout constraints.
質問 # 116
A large enterprise customer is implementing Salesforce. Current systems include ERP for invoicing/fulfillment and a Marketing solution for email. Associates need to view and log interactions in Salesforce. Which system should be the system of record for customers and prospects?
正解：C
解説：
To achieve a "Customer 360" view where sales and service associates have the context needed for daily interactions, Salesforce is the logical System of Record (SoR) for customer and prospect engagement.
While the ERP remains the master for financial transactions (invoices) and the Marketing tool masters campaign analytics, Salesforce should house the core "Golden Record" of the customer. This is achieved by integrating relevant data from the ERP (order status, invoice history) and Marketing (lead source, email engagement) into Salesforce. This strategy (Option A) empowers associates to log interactions and view history in one place, fulfilling the primary goal of the CRM implementation while avoiding the complexity of a new custom database (Option B) or trying to force prospect-level engagement data into a rigid ERP (Option C).
質問 # 117
A global financial company with a core banking system processing 1 million transactions per day wants to build a community portal. Customers need to review their bank account details and transactions. What should an integration architect recommend to enable community users to view their financial transactions?
正解：A
解説：
When dealing with high-volume data (1 million transactions per day) that does not need to be stored natively in Salesforce, the architect should recommend Data Virtualization via Salesforce Connect.
Salesforce Connect allows the company to display external data as External Objects. This approach provides several architectural advantages for a banking community:
No Data Storage: Transactions remain in the core banking system, avoiding the massive storage costs and complex synchronization logic required to house millions of records natively in Salesforce.
Real-Time Visibility: Because External Objects are queried on-demand via the OData protocol or a custom Apex adapter, customers see the most up-to-date transaction history every time they refresh the page.
While an Iframe (Option B) is technically possible, it is often discouraged due to security concerns (such as clickjacking) and a poor user experience, as the Iframe does not natively integrate with Salesforce UI components or reporting. Salesforce Connect provides a "seamless" look and feel, allowing External Objects to be used in related lists and Lightning components just like standard Salesforce records, while keeping the heavy data burden on the performant core banking system.
質問 # 118
Northern Trail Outfitters (NTO) uses a custom mobile app to interact with its customers. One of the features of the app is Salesforce Chatter Feeds. NTO wants to automatically post a Chatter item to Twitter whenever the post includes the #thanksNTO hashtag.
Which API should an integration architect use to meet this requirement?
正解：C
解説：
When designing integrations that specifically involve Chatter, social collaboration, or Experience Cloud sites, the Connect REST API (formerly known as the Chatter REST API) is the architecturally recommended choice. While the standard REST API is optimized for CRUD operations on data records, the Connect REST API is specifically designed to handle the complex, nested structures of social feeds, including posts, comments, hashtags, and mentions.
The Connect REST API provides a specialized resource for feed elements that simplifies the process of identifying specific social markers like hashtags. In this use case, the mobile app or a middleware service can subscribe to or query the feed. The Connect REST API returns structured data where hashtags are identified as distinct message segments, making it trivial for an application logic to detect the #thanksNTO tag and trigger a subsequent call to the Twitter API.
From an architectural standpoint, using the Connect REST API offers several advantages over the standard REST API or Streaming API for this requirement:
Efficiency: Connect REST API responses are structured specifically for presentation in mobile applications, providing only the relevant social metadata and localized content needed for the feed.
Feature Richness: It provides native support for social actions such as liking, sharing, and following, which are often required alongside feed monitoring.
Scalability: It is designed to handle the high-volume, real-time nature of social interactions within Experience Cloud and mobile ecosystems.
While the Streaming API (Option B) can notify an application of record changes, it does not provide the rich, formatted social context that the Connect REST API delivers. The standard REST API (Option A) could technically access FeedItem records, but it would require significant custom parsing logic to identify hashtags within the raw body text, whereas the Connect REST API handles this segmenting natively. Therefore, for building custom mobile experiences that interact with Chatter data, the Connect REST API is the superior solution.
