NEW QUESTION # 86
Northern Trail Outfitters (NTO) has an affiliate company that would like immediate notifications of changes to opportunities in the NTO Salesforce instance. The affiliate company has a CometD client available.
Which solution is recommended in order to meet the requirement?
Answer: C
Explanation:
To provide "immediate notifications" to a client that already supports CometD, the architect must utilize Salesforce's Streaming API. PushTopic Events are the classic Streaming API implementation for broadcasting changes to specific records.
A PushTopic is a definition that includes a SOQL query and a set of trigger events (Create, Update, Delete). When an Opportunity in NTO's instance is updated and matches the query, Salesforce automatically pushes a notification to the topic's channel. The affiliate's CometD client, having subscribed to this channel, receives the data payload instantly.12 Option A (Polling) is the architectural opposite of "immediate notifications". Polling is inefficient, consumes API limits, and int13roduces latency between the actual record change and the client's discovery of that change. Option C is incorrect as there is no "Accept CometD" setting in a Connected App; while a Connected App is used for OAuth authentication, the PushTopic is the mechanism that actually defines and delivers the stream. By using PushTopic, NTO provides a decoupled, event-driven architecture that fulfills the requirement for real-time visibility while minimizing the technical burden on the affiliate's infrastructure.
NEW QUESTION # 87
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.
Their current response times could take up to 90 seconds to process and return.
These eligibility systems are accessed through APIs orchestrated via ESB (MuleSoft).
All requests from Salesforce traverse the customer's API Gateway layer, which imposes a timeout constraint of 9 seconds.
Which recommendation should the integration architect make?
Answer: B
Explanation:
In this architectural scenario, the Integration Architect must navigate two critical technical "bottlenecks": the 9-second API Gateway timeout and the 90-second backend processing time. Since the backend takes significantly longer than the gateway allows for a synchronous connection, a standard Request-Reply pattern will fail. Furthermore, having 3,000 concurrent agents perform synchronous callouts would risk hitting Salesforce's concurrent long-running request limits.
The most scalable and user-friendly solution is to implement an Asynchronous Request-Reply pattern using Platform Events and the empAPI.
When an agent clicks "Check Eligibility," Salesforce sends an initial asynchronous request to the ESB (MuleSoft). The ESB immediately acknowledges receipt with a 202 Accepted status, freeing up the Salesforce UI thread and avoiding the API Gateway's 9-second timeout. Once the backend eligibility system completes its 90-second process, MuleSoft acts as a client to Salesforce, performing a Remote Call-In to publish a specific Platform Event containing the result and the original Request ID.
On the frontend, the Lightning UI uses the empAPI (Enterprise Messaging Platform API) to subscribe to the streaming channel for that Platform Event. Because the empAPI uses CometD technology to maintain a single long-lived connection, it can efficiently push the response to the agent's screen the moment it arrives, without requiring the agent to manually refresh or click a "Check Update" button (as suggested in Option B). This provides a "real-time" feel despite the long backend latency.
Option A is non-viable because synchronous polling would exacerbate the load on the API Gateway and likely lead to governance limit issues within Salesforce. By using Platform Events and empAPI, the architect ensures the solution remains within Salesforce's execution limits while providing a seamless, automated experience for a high-volume call center environment.
NEW QUESTION # 88
Northern Trail Outfitters needs a low-code, near real-time REST integration to an ERP when an Order is created. They have limited development resources. Which option should fulfill the use case requirements?
Answer: B
Explanation:
For a team with limited development resources and a low-code requirement, Lightning Flow (Flow Builder) is the primary declarative engine for modern integrations.
In this scenario, creating a Platform Event via a record-triggered flow provides a highly scalable, near real-time "Fire-and-Forget" signal to the middleware. This is considered low-code because it can be built entirely using point-and-click tools within Salesforce. Once the Order is created, the flow publishes the event to the bus. The middleware, acting as a subscriber, receives the event and orchestrates the REST call to the ERP.
Option C (Outbound Messaging) is also a low-code tool, but it natively sends messages in SOAP format. Since the ERP requires a REST endpoint, using Outbound Messaging would necessitate additional transformation logic in the middleware, making it a less efficient architectural choice than using a Flow to trigger an event or an External Service. Option B (Change Data Capture) is a powerful tool but often requires more advanced "pro-code" configuration on the subscriber/middleware side to handle Replay IDs and Bayeux protocols, which might exceed the "limited resources" constraint of the Salesforce team.
NEW QUESTION # 89
Universal Containers (UC) is currently managing a custom monolithic web service that runs on an on-premise server. This monolithic web service is responsible for Point-to-Point (P2P) integrations between Salesforce and a legacy billing application, a cloud-based ERP, and a data lake. UC has found that the tight interdependencies are causing failures. What should an integration architect recommend to decouple the systems and improve performance?
Answer: A
Explanation:
The primary architectural flaw in UC's current landscape is the reliance on a monolithic P2P integration layer. In such designs, any failure in one integration thread or a surge in volume for one system can monopolize resources (CPU, memory, threads), causing the entire service-and thus all other integrations-to fail. This lack of isolation leads to the "tight interdependencies" described.
To effectively decouple these systems, the architect should recommend a Microservices Architecture. By breaking the monolithic service into smaller, independent, and modular components, each integration (Billing, ERP, Data Lake) becomes its own isolated service. This approach provides several key architectural benefits:
Isolation of Failure: If the connection to the legacy billing application fails or times out, it no longer impacts the ERP or Data Lake integrations.
Independent Scalability: If the Data Lake integration requires high throughput, that specific microservice can be scaled horizontally without wasting resources on the others.
Technology Agility: Each microservice can be updated or patched independently, allowing for faster maintenance cycles.
Furthermore, moving a "monolithic" service to the cloud (Option B) is simply a "lift and shift" that preserves the underlying fragility. While the Bulk API (Option A) is excellent for high-volume data loading, it does not solve the fundamental problem of system interdependency and orchestration failure. Transitioning to a modular, service-oriented design allows UC to implement modern integration patterns, such as asynchronous queuing between the microservices, which significantly improves the overall resilience and performance of the Salesforce-to-back-office landscape.
NEW QUESTION # 90
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?
Answer: A
Explanation:
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.
