問題 #81
Northern Trail Outfitters has recently implemented middleware for orchestration of services across platforms. The Enterprise Resource Planning (ERP) system being used requires transactions be captured near real-time at a REST endpoint initiated in Salesforce when creating an Order object. Additionally, the Salesforce team has limited development resources and requires a low-code solution. Which option should fulfill the use case requirements?
答案：A
解題說明：
To satisfy a requirement for near real-time REST updates with limited development resources, the architect should utilize Flow Builder. Flow Builder is Salesforce's primary low-code tool for automating complex business logic and outbound integrations.
The Remote Process Invocation-Fire and Forget pattern is the most efficient way to signal an external system (or middleware) that a record was created without blocking the user. Using a Record-Triggered Flow on the Order object, the architect can configure an Action (such as an External Service or a simple HTTP Callout) to send the order data to the middleware's REST endpoint.
Option A is slightly incorrect because creating a platform event is just one step in an event-driven flow; the "Fire and Forget" pattern more accurately describes the end-to-end intent. Option B (Change Data Capture) is a powerful tool, but it is considered a "pro-code" or high-configuration so12lution on the middleware side, requiring the middleware to manage Replay IDs and Bayeux subscriptions. Option C leverages the native strengths of Flow to fulfill the requirement declaratively, 13allowing the team to14 deliver a functional integration without writing Apex code while meeting the near-real-time performance expectations of the ERP.

Northern Trail Outfitters has recently implemented middleware for orchestration of services across platforms. The Enterprise Resource Planning (ERP) system being used requires transactions be captured near real-time at a REST endpoint initiated in Salesforce when creating an Order object. Additionally, the Salesforce team has limited development resources and requires a low-code solution. Which option should fulfill the use case requirements?12
答案：C
解題說明：
To satisfy a requirement for near real-time updates to an ERP system while adher9ing to a low-code constraint, the architect must leverage Salesforce's modern declara10tive automation tools. The goal is to initiate an outbound signal that the existing middleware can then orchestrate and deliver to the ERP's REST endpoint.
The Remote Process Invocation-Fire and Forget pattern is perfectly suited for this scenario. In this pattern, Salesforce sends a message to an external system and does not wait for a functional response. This is ideal for "capturing" transactions in an ERP where the primary goal is record synchronization rather than a real-time calculation return. By using Flow Builder, the team can implement a record-triggered flow on the Order object. This flow can be configured to execute "Actions" that send data to the middleware via External Services or standard HTTP Callouts (Beta/GA features in modern Flow), which requires zero Apex coding.
Option B, Outbound Messaging, is a legacy declarative tool that is highly reliable but has a significant limitation: it natively sends messages in SOAP format. Since the requirement specifically specifies a REST endpoint, using Outbound Messaging would require additional transformation logic in the middleware, making it a less direct architectural fit than a modern Flow-based REST call. Option C, Change Data Capture (CDC), is a highly scalable, event-driven mechanism, but it is typically considered more complex to implement and maintain. It requires the middleware to manage "Replay IDs" and subscribe to a streaming channel, which often requires more specialized development effort on the middleware side compared to a simple HTTP POST from a Flow. For a team with limited development resources, Flow Builder provides the most accessible and maintainable path to achieving near real-time integration.
問題 #83
Northern Trail Outfitters has a registration system that is used for workshops offered at its conferences. Attendees use Salesforce Community to register for workshops, but the scheduling system manages workshop availability based on room capacity. It is expected that there will be a big surge of requests for workshop reservations when the conference schedule goes live. Which Integration pattern should be used to manage the influx in registrations?
答案：C
解題說明：
When dealing with a "big surge" or high-volume influx of requests, a synchronous pattern like Request and Reply (Option A) can lead to significant performance bottlenecks. In a synchronous model, each Salesforce user thread must wait for the external scheduling system to respond, which could lead to "Concurrent Request Limit" errors during peak times.
The Remote Process Invocation-Fire and Forget pattern is the architecturally sound choice for managing surges. In this pattern, Salesforce captures the registration intent and immediately hands it off to an asynchronous process or a middleware queue. Salesforce does not wait for the external system to process the room capacity logic; instead, it receives a simple acknowledgment that the message was received.23 This pattern decouples the front-end user experience from the back-end processing limits. Middleware can then "drip-feed" these registration4s into the scheduling system at a rate it can handl5e. If the scheduling system becomes overwhelmed or goes offline, the messages remain safely in the queue. Option C (Batch) is unsuitable because users expect near real-time feedback on their registration attempt, even if the final confirmation is sent a few minutes later. By utilizing Fire and Forget, NTO ensures a responsive Community Experience during the critical launch window while maintaining system stability.
問題 #84
A company's cloud-based single page application consolidates data local to the application with data from on-premise and Third-party systems. The diagram below typifies the application's combined use of synchronous and asynchronous calls. The company wants to use the average response time of its application's user interface as a basis for certain alerts. For this purpose, the following occurs:
Log every call start and finish date and time to a central analytics data store.
Compute response time uniformly as the difference between the start and finish date and time (A to H in the diagram).
Which computation represents the end-to-end response time from the user's perspective?
答案：C
問題 #85
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?
答案：B
解題說明：
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.
