Salesforce Certified Platform Integration Architect Sample Questions (Q110-Q115):NEW QUESTION # 110
Universal Containers (UC) is a global financial company that sells financial products and services. There is a daily scheduled Batch Apex job that generates invoices from a given set of orders. UC requested building a resilient integration for this Batch Apex job in case the invoice generation fails. What should an integration architect recommend to fulfill the requirement?
  • A. Build Batch Retry and Error Handling in the Batch Apex job itself.
  • B. Build Batch Retry and Error Handling using BatchApexErrorEvent.
  • C. Build Batch Retry and Error Handling in the middleware.
Answer: B
Explanation:
Resiliency in long-running Batch Apex processes is best achieved by utilizing modern, event-driven error handling frameworks provided by the Salesforce platform. The BatchApexErrorEvent is the architecturally recommended component for monitoring and responding to failures in Batch Apex jobs.
When a Batch Apex class implements the `Database.RaisesPlatformEvents` interface, the platform automatically publishes a BatchApexErrorEvent whenever an unhandled exception occurs during the execution of a batch. This event contains critical metadata, including the exception message, the stack trace, and the scope (the specific IDs of the records that were being processed when the failure occurred).
An Integration Architect should recommend building a Platform Event Trigger that subscribes to these error events. This trigger can perform sophisticated error handling logic, such as:
* Logging the failure details into a custom "Integration Error" object for auditing.
* Initiating a retry logic by re-enqueuing only the failed records into a new batch job.
* Notifying administrators or external systems via an outbound call or email.
This approach is superior to Option B (internal handling) because unhandled exceptions often cause the entire batch transaction to roll back, potentially losing any error logging performed within the same scope. It is also more efficient than Option C (middleware), as it keeps the error recovery logic "close to the data," reducing the need for external systems to constantly poll for job status or parse complex logs. By using BatchApexErrorEvent, UC ensures a resilient, self-healing process that maintains the integrity of the invoice generation cycle.

NEW QUESTION # 111
An enterprise customer with more than 10 million customers has the following systems and conditions in its landscape:
Enterprise Billing System (EBS) - All customers' monthly billing is generated by this system.
Enterprise Document Management System (DMS) - Bills mailed to customers are maintained in the Document Management system.
Salesforce CRM (CRM) - Customer information, sales, and support information is maintained in the CRM.
Only authorized users are allowed access to the EBS and the Enterprise DMS. Customers call Customer Support when they need clarification on their bills. Customer Support needs seamless access to customer billing information from the EBS and to view generated bills from the DMS. Which authorization and authentication need should an integration consultant consider while integrating the DMS and EBS with Salesforce?
  • A. Identify options to maintain DMS and EBS authentication and authorization details in Salesforce.
  • B. Consider Enterprise security needs for access to DMS and EBS.
Answer: B
Explanation:
When integrating high-security back-office systems like an Enterprise Billing System (EBS) and a Document Management System (DMS) with Salesforce, the primary concern for an Integration Architect is maintaining the integrity of the organization's existing security perimeter. In an enterprise landscape with over 10 million customers, these systems are typically governed by strict regulatory and compliance standards (such as PCI-DSS or GDPR) that dictate who can view financial records.
The consultant must consider Enterprise security needs for access to these systems rather than simply attempting to synchronize credentials. This involves evaluating an Identity Federation strategy using protocols like SAML 2.0 or OpenID Connect. Instead of maintaining a separate silo of authentication details within Salesforce (which creates a security risk and administrative overhead), Salesforce should act as a Service Provider (SP) that trusts a central Identity Provider (IdP).1234 Furthermore, the "seamle5ss access" requirement implies that once a support agent is authenticated into Salesforce, their identity should be propagated to the EBS and DMS to authorize the specific 6view of a7 customer's bill. This is often achieved through Single Sign-On (SSO) and Token-Based Authentication8. By prioritizing the enterprise security framewo9rk, the architect ensures that access is auditable, centralized, and compliant with corporate policies, while providing th10e "360-degree" view required by support agents without forcing them to log in to multiple disconnected systems. Migrating such massive systems (Option A) into Salesforce is technically and financially unfeasible for most enterprises due to data volume and specialized processing logic.

NEW QUESTION # 112
Universal Containers (UC) has a legacy homegrown application that stores customer data. Sales representatives edit contact records in Salesforce. UC requirements: 1. Salesforce updates should update the homegrown application. 2. Synchronization should be event-driven. 3. Integration should be asynchronous. Which option should an architect recommend?
  • A. Leverage Platform Events to publish a custom event message containing changes to the Contact object.
  • B. Leverage Change Data Capture to track changes to the Contact object and write a CometD subscriber on the homegrown application.
Answer: B
Explanation:
For a requirement focused on synchronizing record updates from Salesforce to an external system in an event-driven and asynchronous manner, Change Data Capture (CDC) is the architecturally preferred solution over custom Platform Events.
CDC is designed specifically for data replication and synchronization. It automatically publishes change events for Salesforce records (Create, Update, Delete, and Undelete) to the event bus. Unlike Platform Events, which require manual publishing via Apex triggers or Flows, CDC is a low-code feature that requires only a simple activation for the Contact object in Setup. The external homegrown application can then act as a CometD subscriber, listening to the specialized /data/ContactChangeEvent channel to receive near real-time updates without the need for constant polling. Furthermore, CDC provides ordered, replayable events and an extended 72-hour retention window, ensuring that the homegrown application can recover missed updates using a Replay ID if it momentarily loses connection. This native broadcasting capability ensures data integrity across systems while breaking the tight coupling between Salesforce and the legacy application.

NEW QUESTION # 113
Salesforce is the system of record for Leads, Contacts, Accounts, and Cases. Customer data also exists in an ERP, ticketing system, and data lake, each with unique identifiers. Middleware is used to update systems bidirectionally. Which solution should be recommended to handle this?
  • A. Use Change Data Capture to update downstream systems accordingly.
  • B. Design an MDM solution that maps external IDs to the Salesforce record ID.
  • C. Locally cache external IDs at the middleware layer.
Answer: B
Explanation:
In a complex landscape where multiple systems contain overlapping customer data, each with its own primary key, the core architectural challenge is Identity Management. To ensure that an update in Salesforce (the System of Record) correctly updates "Customer A" in the ERP and "Customer A" in the Data Lake, a Master Data Management (MDM) strategy is required.
An MDM solution creates a Cross-Reference (X-Ref) Table or a "Golden Record" that maps the unique identifiers from all systems. In the Salesforce record, the architect should implement External ID fields for each corresponding system (e.g., ERP_ID__c, Ticket_System_ID__c).
Why this is the superior recommendation:
Bidirectional Integrity: When the middleware receives an update from the ERP, it uses the ERP_ID__c to perform an "upsert" in Salesforce, ensuring no duplicates are created.
Traceability: It allows for easy auditing of data lineage across the enterprise.
Decoupling: Salesforce doesn't need to know the internal logic of the ERP; it simply holds the reference key.
Option B (CDC) is a delivery mechanism, not an identity management strategy; it tells you that something changed, but not which record in the ERP it corresponds to without the ID mapping. Option C (Local caching in middleware) is an "anti-pattern" because it makes the middleware stateful; if the middleware cache is lost or out of sync, the entire integration breaks. By designing an MDM-based mapping solution directly within the data model, the architect ensures a robust, scalable, and transparent identity framework for the entire enterprise.

NEW QUESTION # 114
A company accepts payment requests 24/7. Once the company accepts a payment request, its service level agreement (SLA) r5equires it to make sure each payment request is processed by its Payment System. The co6mpany tracks payment requests using a globally unique identifier created at the Data Entry Point. The company's simplified flow is as shown in the diagram.

The company encounters intermittent update errors when two or more processes try to update the same Payment Request record at the same time.
Which recommendation should an integration architect make to improve the company's SLA and update conflict handling?
  • A. Payment System and Middleware should automatically retry requests.
  • B. Middleware should coordinate request delivery and payment processing.
  • C. Data Entry Point and Middleware should automatically retry requests.
Answer: B
Explanation:
To fulfill the SLA of ensuring every payment is processed while simultaneously resolving the issue of intermittent update errors, the architect must introduce an orchestration layer capable of managing state and concurrency. In a high-volume payment environment, "Fire and Forget" messages (as seen in the provided diagram) can lead to race conditions if multiple threads attempt to update a single record simultaneously-a common challenge when scaling payment systems.
The recommendation to have Middleware coordinate request delivery and payment processing (Option C) transforms the architecture into a managed queueing system. By coordinating delivery, the middleware can act as a traffic controller, ensuring that requests are delivered sequentially or that appropriate locks are respected before an update is attempted. This orchestration allows the system to meet its SLA by implementing a "guaranteed delivery" pattern, where the middleware tracks the status of each payment and only "forgets" the message once the Payment System confirms successful processing.
Furthermore, the architect should emphasize idempotency by leveraging the globally unique identifier created at the Data Entry Point. The Payment System should be designed to use this identifier to check if a specific transaction has already been processed before attempting an update. This prevents duplicate entries and conflicting updates, even if the middleware retries a message due to a network timeout. While retries (Options A and B) are part of a resilient system, they do not solve the root cause of record contention; only the coordination and sequencing provided by the middleware can ensure a stable, conflict-free integration flow.78
