Salesforce Certified Platform Integration Architect Sample Questions (Q126-Q131):

NEW QUESTION # 126
The director of customer service at Northern Trail Outfitters (NTO) wants to capture and trend specific business events that occur in Salesforce in real time. The metrics will be accessed in an ad-hoc manner using an external analytics system. The events include product exchanges, authorization clicks, subscription cancellations, and refund initiations via Cases. Which solution should meet these business requirements?

Answer: B

Explanation:
To meet a requirement for real-time event capture that supports an external analytics system, the arc14hitect must choose a pattern that is scalable, decoupled, and reliable. Platform Events are the modern standard for this use case.
By using a Case Trigger to publish a specific Platform Event, NTO creates a highly decoupled Publish/Subscribe architecture. The external analytics system (or a middleware layer feeding it) acts as a subscriber to the event channel. This is superior to standard callouts or outbound messaging for several reasons:
Durability: Platform Events offer a 72-hour retention window. If the analytics system is momentarily offline, it can use the Replay ID to retrieve missed events.
Atomic Transactions: Triggers can be configured to publish events only after the database transaction successfully commits ("Publish After Commit"), ensuring the analytics system doesn't receive data for transactions that were eventually rolled back.
Event Volume: Platform Events are designed to handle much higher volumes of real-time messages than standard synchronous callouts.
Option A (Apex Callouts) is a point-to-point, synchronous pattern that would block Case processing and risk hitting "Concurrent Long-Running Request" limits. Option B (Outbound Messaging) is reliable but is limited to a single object per message and uses a rigid SOAP format that is less flexible for ad-hoc external analytics than the modern JSON/CometD/gRPC structures used by the event bus. By implementing Option C, the architect ensures that every specific business milestone (refund, exchange, cancellation) is broadcasted immediately, providing the customer service director with the accurate, real-time visibility required for trending and metrics.


NEW QUESTION # 127
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: A

Explanation:
To provide near real-time notifications to a client that already supports CometD, an Integration Architect should leverage the Streaming API. While Platform Events are a modern alternative, PushTopic Events are specifically designed to stream changes to Salesforce records based on a defined SOQL query.
A PushTopic event is triggered when a record is created, updated, deleted, or undeleted. By creating a PushTopic on the Opportunity object, NTO defines the criteria (fields and record states) that should trigger a message to the 1subscriber. The affiliate's CometD client can then subscribe to this topic's channel (e.g., /topic/OpportunityUpdates) to receive the data payload instantly.
Option A is incorrect because "Accept CometD API Requests" is not a standard checkbox or configuration within a Connected App; authentication is handled via standard OAuth flows, but the streaming channel must still be defined. Option C describes a Polling mechanism, which is the architectural opposite of the requested "immediate notification" and would unnecessarily consume SOAP API limits while introducing latency. By using a PushTopic, NTO ensures a decoupled, event-driven architecture that scales effectively for notification-only use cases while respecting the technical capabilities of the affiliate's existing CometD-compatible infrastructure.


NEW QUESTION # 128
An architect decided to use Platform Events for integrating Salesforce with an external system for a company. What should an architect consider when proposing this type of integration mechanism?

Answer: C

Explanation:
When proposing Platform Events as an integration mechanism, an architect must ensure that the security model is correctly configured to allow for the publication and subscription of events. Unlike standard objects, Platform Events have specific permission requirements for the "Integration User" or any system entity interacting with the event bus.
For an external system to subscribe to a Platform Event stream (via CometD or the Pub/Sub API), the user account used to authenticate the connection must have the "Read" permission on the specific Platform Event entity. Similarly, if the external system needs to publish events back into Salesforce, the user must have "Create" permissions. These permissions are typically managed through a Profile or a Permission Set assigned to the Integration User.
Regarding the other options, Option A is incorrect because Platform Events are designed for asynchronous communication. They are inherently decoupled; the external system does not need the same uptime as Salesforce. High-volume platform events are stored in the event bus for 72 hours, allowing an external system to "catch up" using a Replay ID once it comes back online. Option C is also incorrect because Platform Events follow a Publish/Subscribe pattern. Salesforce "broadcasts" the event to the bus without needing to know which specific external systems are listening. This decoupling is a primary advantage of event-driven architecture, as it allows for a "one-to-many" distribution model where multiple systems can consume the same message without additional configuration within Salesforce. Thus, ensuring the correct object-level permissions (Read/Create) is the most critical technical consideration for the architect to guarantee successful message delivery.


NEW QUESTION # 129
Northern Trail Outfitters is planning to perform nightly batch loads into Salesforce using the Bulk API. The CIO is curious about monitoring recommendations for the jobs from the technical architect. Which recommendation should help meet the requirements?

Answer: C


NEW QUESTION # 130
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: A

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.
