Salesforce Certified Platform Integration Architect Sample Questions (Q90-Q95):NEW QUESTION # 90
A customer is evaluating the Platform Events solution and would like help in comparing/contrasting it with Outbound Messaging for real-time/near-real time needs. They expect 3,000 customers to view messages in Salesforce. What should be evaluated and highlighted when deciding between the solutions?12
  • A. Message sequence is possible in Outbound Messaging, but not guaranteed with Platform Events. Both offer very high reliability. Fault handling and recovery are fully handled by Salesforce.
  • B. In both Platform Events and Outbound Messaging, the event messages are retried by and delivered in sequence, and 3only once. Sales4force ensures there is no duplicate message delivery.
  • C. Both Platform Events and Outbound Messaging are highly scalable. However, unlike Outbound Messaging, only Platform Events have Event Delivery and Event Publishing limits to be considered.
Answer: C
Explanation:
When comparing Platform Events and Outbound Messaging for a near-real-time architecture, a Salesforce Platform Integration Architect must evaluate fundamental differences in their delivery models and governance. While both provide declarative, asynchronous "Fire-and-Forget" capabilities, their technical constraints differ significantly, particularly regarding scalability and platform limits.
The key architectural highlight in this scenario is that Platform Events operate on a specialized event bus with specific Event Publishing and Event Delivery limits. Unlike Outbound Messaging, which is governed by more general daily outbound call limits (often tied to user licenses), Platform Events have a dedicated allocation for the number of events that can be published per hour and delivered in a 24-hour period to external clients via the Pub/Sub API or CometD. For example, the number of concurrent subscribers to a Platform Event channel is typically capped at 2,000 for standard configurations. Since the customer expects 3,000 customers to view these messages, this limit is a critical evaluation point; the architecture would need to account for this gap, perhaps by using middleware to fan out messages to the larger audience.
In contrast, Outbound Messaging does not have an "Event Delivery" limit in the same sense. It is a point-to-point SOAP-based push mechanism where Salesforce manages retries for up to 24 hours if the receiving endpoint is unavailable. However, it is less flexible for multi-consumer scenarios because it requires a separate configuration for every unique destination.
Regarding the other options: Option A is incorrect because neither system strictly guarantees "exactly-once" delivery without the possibility of duplicates; in fact, Outbound Messaging may deliver a message more than once if it doesn't receive a timely acknowledgment. Option B is incorrect because Platform Events do not have built-in "fault recovery" handled by Salesforce in the same way as Outbound Messaging's automatic retry queue; with Platform Events, it is the subscriber's responsibility to use a Replay ID to retrieve missed events within the 72-hour retention window. Therefore, highlighting the unique delivery and publishing limits is the most vital step for the architect.

NEW QUESTION # 91
Northern Trail Outfitters (NTO) has recently changed its Corporate Security Guidelines. The guidelines require that all cloud applications pass through a secure firewall before accessing on-premise resources. NTO is evaluating middleware solutions to integrate cloud applications with on-premise resources and services. Which consideration should an integration architect evaluate before choosing a middleware solution?12
  • A. The middleware solution enforces the OAuth security protocol.
  • B. The middleware solution is able to interface directly with databases via an5 Open Database Connectivity (ODBC) con6nection string.
  • C. An API Gateway component is deployable behind a Demilitarized Zone (DMZ) or perimeter network.
Answer: C
Explanation:
In modern enterprise architecture, securing the boundary between cloud environments like Salesforce and on-premise data centers is a critical responsibility of the Integration Architect. When Corporate Security Guidelines mandate that all traffic must pass through a secure firewall, the architecture must support a Demilitarized Zone (DMZ) or "erimeter Network" strategy.
An API Gateway or a specialized middleware connector acts as the "front door" for these on-premise resources. The architect must evaluate whether the chosen middleware solution supports a distributed deployment model where the gateway component can reside within the DMZ. This setup allows the organization to terminate external (cloud) connections in a hardened environment before the traffic is inspected and proxied to the internal, trusted network.
While supporting OAuth (Option C) is essential for modern authentication, it does not satisfy the specific network-level firewall requirement described. Similarly, ODBC connections (Option B) are low-level database protocols that usually operate deep within the internal network and would typically be considered a security risk if exposed directly to a firewall.
By ensuring the middleware has an architecturally compatible gateway for the DMZ, the architect provides a solution that allows for deep packet inspection, IP whitelisting, and rate limiting at the edge of the corporate network. This approach aligns with the "Defense in Depth" principle, ensuring that Salesforce can securely communicate with legacy systems (like SAP or internal databases) without exposing those systems directly to the public internet, thereby satisfying the new Corporate Security Guidelines.

NEW QUESTION # 92
Universal Containers (UC) is a leading provider of management training globally. UC embarked on a Salesforce transformation journey to allow students to register for courses in the Salesforce Community. UC has a learning system that masters all courses and student registration. UC requested a near real-time feed of student registration from Salesforce to the learning system. The integration architect recommends using Salesforce Platform Events. Which API should be used for the Salesforce pl1atform event solution?
  • A. Streaming API
  • B. REST API
  • C. SOAP API
Answer: A
Explanation:
Salesforc30e Platform Events are built on top of a highly scalable, event-driven messaging architecture designed to enable real-time communication between apps. To consume these events from outside Salesforce-such as from a legacy learning system-clients must use the Streaming API.
The Streaming API is the technical foundation for receiving event notifications in a Publish/Subscribe model. It utilizes the CometD protocol or the newer gRPC-based Pub/Sub API to maintain a persistent connection between the external client and Salesforce. When a student registers for a course in the Salesforce Community, a Platform Event is "published" to the event bus. The learning system, acting as a "subscriber," remains connected via the Streaming API and receives the event message instantly without needing to poll Salesforce for updates.
This architecture is ideal for "near real-time" requirements because it eliminates the overhead of traditional point-to-point integrations. While the REST and SOAP APIs (Options A and B) can be used to publish events into Salesforce, they are not designed to receive unsolicited notifications from the platform. By using the Streaming API, the integration architect ensures the solution is both responsive and efficient, as Salesforce only pushes data when a relevant event occurs. Furthermore, because Platform Events provide a retention window, the Streaming API allows the learning system to use a Replay ID to catch up on any registration events missed during a brief network outage.

NEW QUESTION # 93
Universal Containers (UC) works with third-party agents on banner initial design concepts. The design files (2.5 GB) are stored in an on-premise file store. UC wants to allow agencies to view these files in the community. Which solution should an integration architect recommend?
  • A. Use Salesforce Files to link the files to Salesforce records and display the record and the files in the community.
  • B. Create a Lightning component with a Request and Reply integration pattern to allow the community users to download the design files.
  • C. Create a custom object to store the file location URL; when a community user clicks on the file URL, redirect the user to the on-premise system file location.
Answer: C
Explanation:
When dealing with extremely large files, such as the 2.5 GB design files mentioned, an architect must consider the platform's file size limits and storage costs. Salesforce Files have a maximum upload size of 2 GB through most interfaces, making Option B technically unfeasible for a 2.5 GB file. Furthermore, storing numerous large files natively in Salesforce would lead to excessive storage consumption and costs.
The most efficient and cost-effective approach is Data Virtualization or Redirection. By creating a custom object to store the file location URL (Option C), the actual file remains in the performant on-premise file store. When the community user needs to access the design, they are redirected to the source system, which handles the massive data transfer. This fulfills the requirement to "view" the files without the overhead of moving gigabytes of data through the Salesforce infrastructure. Option A is less ideal because a 2.5 GB download over a standard Request-Reply pattern would likely lead to timeouts and a poor user experience.

NEW QUESTION # 94
Northern Trail Outfitters submits orders to the manufacturing system web service. Recently, the system has experienced outages that keep service unavailable for several days. Which solution should an integration architect recommend to handle errors during these types of service outages?1718
  • A. Use middleware queuing and buffering to insulate Salesforce from1920 system outages.
  • B. Use Platform Event replayId and custom scheduled Apex process to retrieve missed events.
  • C. Use Outbound Messaging to automatically retry failed service calls.
Answer: A
Explanation:
When a target system experiences prolonged outages (lasting "several days"), point-to-point integrations built directly within Salesforce are prone to failure because they lack the persistence required for long-term retries. The architecturally sound recommendation is to utilize middleware queuing and buffering to "insulate" Salesforce from the target system's instability.
In this architecture, Salesforce sends the order to a middleware layer (such as an ESB or iPaaS). The middleware immediately acknowledges receipt of the message, freeing up Salesforce resources. If the manufacturing system is offline, the middleware stores the order in a persistent Message Queue. Unlike Salesforce Outbound Messaging (Option B), which only retries for up to 24 hours, enterprise middleware can be configured to hold messages for days or even weeks.
Middleware also provides sophisticated Quality of Service (QoS) features, such as "Dead Letter Queues" for manual intervention and customized retry schedules (e.g., retrying every hour instead of every few minutes). This decoupling ensures that Salesforce users can continue to create and "send" orders without seeing technical errors, even while the backend manufacturing system is down. Once the manufacturing service is restored, the middleware "drains" the queue, delivering all buffered orders in the correct sequence. This strategy provides the highest level of reliability and resilience for mission-critical business processes.
