NEW QUESTION # 60
Northern Trail Outfitters uses Salesforce to track leads and opportunities, and to capture order details. However, Salesforce isn't the system that holds or processes orders. After the order details are captured in Salesforce, an order must be created in the Remote system, which manages the order's lifecycle. The integration architect for the project is recommending a remote system that will subscribe to the platform event defined in Salesforce. Which integration pattern should be used for this business use case?
Answer: B
Explanation:
In this scenario, Salesforce acts as the trigger for a business process that completes in an external system. The architect's recommendation for the remote system to subscribe to a platform event is the classic implementation of the Remote Process Invocation-Fire and Forget pattern.1 In a Fire and Forget pattern, Salesforce initiates a process by publishing a message (the event) to the event bus and then immediately continues its own2 processing without waiting for a functional response from the target system. The "Fire" part occurs when the order details are captured and the event is published; the "Forget" part refers to Salesforce handing off the responsibility of order creation to the remote system. This pattern is ideal for improving user experience and system performance, as it avoids blocking the user interface while waiting for potentially slow back-office systems to respond.
Option A (Request and Reply) is incorrect because that would require Salesforce to make a synchronous call and wait for the remote system to confirm the order was created before allowing the user to proceed. Option C (Remote Call-In) is the inverse of what is described; it would involve the remote system actively reaching into Salesforce to "pull" the data, whereas here Salesforce is "pushing" the notification via an event stream. By using Platform Events to facilitate this hand-off, Northern Trail Outfitters ensures a decoupled, scalable architecture where the remote system can process orders at its own pace while Salesforce remains responsive to sales users.
NEW QUESTION # 61
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: B
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 # 62
Northern Trail Outfitters requires an integration to be set up between one of its Salesforce orgs and an External Data Source using Salesforce Connect. The External Data Source supports Open Data Protocol. Which configuration should an integration architect recommend be implemented in order to secure requests coming from Salesforce?
Answer: C
Explanation:
Salesforce Connect is a powerful tool for data virtualization, allowing users to view and manage data in external systems (via OData) as if it were stored natively in Salesforce. However, a critical security decision during the setup of an External Data Source is determining the Identity Type.
The Identity Type determines how the external system authenticates the Salesforce user. There are two primary options:
Named Principal: Every Salesforce user accesses the external system using the same set of credentials. This is easier to maintain but provides less granular security tracking in the target system.
Per User: Each individual Salesforce user must provide their own credentials for the external system. This ensures that the data visible in Salesforce respects the user's specific permissions in the external source.
Configuring the Identity Type is the fundamental way an architect secures OData requests because it defines the authentication boundary between the platforms. While certificates (Option A) can be used for transport layer security, the "Identity Type" configuration is the specific Salesforce Connect setting that governs how a session is authorized. Option B (Special Compatibility) is a technical setting used to handle non-standard OData implementations and does not directly relate to securing the request. By recommending the correct Identity Type, the architect ensures that the integration adheres to the "Principle of Least Privilege," ensuring that users only see the external data they are authorized to access.
NEW QUESTION # 63
The URL for a business-critical external service providing exchange rates changed without notice. Which solutions should be implemented to minimize potential downtime for users in this situation?
Answer: C
Explanation:
To minimize downtime when an external endpoint changes, an Integration Architect must ensure that the URL is not "hardcoded" within Apex code or configuration. The standard Salesforce mechanism for abstracting and managing external endpoints is Named Credentials.
Named Credentials specify the URL of a callout endpoint and its required authentication parameters in one definition. If the URL changes, an administrator simply updates the "URL" field in the Named Credential setup. This change takes effect immediately across all Apex callouts, Flows, and External Services that reference it, without requiring a code deployment or a sandbox-to-production migration.
Along with Named Credentials, Remote Site Settings (or the more modern External Website Configurations) are required. Salesforce blocks all outbound calls to URLs that are not explicitly whitelisted.
By having both in place, the remediation process is:
Update the URL in the Named Credential.
Update (or add) the new URL in the Remote Site Settings.
This approach follows the "Separation of Concerns" principle. Option B (ESB) could technically handle this, but it adds an extra layer of failure and complexity for a simple URL change. Option C (Content Security Policies) is used to control which resources (like scripts or images) a browser is allowed to load in the UI; it does not govern server-side Apex callouts. Therefore, the combination of Named Credentials and Remote Site whitelisting is the most efficient and standard way to provide architectural agility and minimize downtime.
NEW QUESTION # 64
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?
Answer: C
Explanation:
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.
