NEW QUESTION # 81
A business requires automating the check and updating of the phone number type classification for all incoming calls. Up to 100,000 calls per day are received, and the business is flexible with timing (every 6-12 hours is sufficient). A Remote-Call-In and/or Batch Synchronization pattern via middleware is planned. Which component should an integration architect recommend to implement these patterns?
Answer: A
Explanation:
In a Remote-Call-In or Batch Synchronization pattern where an external middleware initiates the connection to Salesforce, the external system must be authenticated. The standard Salesforce framework for this is the Connected App.
A Connected App provides a framework for external applications to integrate with Salesforce using APIs and standard protocols like OAuth 2.0. For a high-volume (100,000 records) batch process initiated by middleware every 6-12 hours, the architect would recommend a Connected App using a secure flow, such as the OAuth 2.0 JWT Bearer Flow. This allows the middleware to authenticate as a specific "Integration User" without storing clear-text passwords.
Option A (API Gateway) is used to manage and secure outbound calls from Salesforce or between external services; it does not handle inbound authentication to the Salesforce org itself. Option B (Remote Site Settings) is a whitelist configuration used purely to allow Salesforce to make outbound callouts to a specific URL; it provides no authentication mechanism for systems calling into Salesforce. By recommending a Connected App, the architect ensures that the middleware has the necessary permissions (scopes) to use the Bulk API-which is the appropriate mechanism for the 100,000 record volume-while maintaining a secure, auditable, and standard integration boundary.
NEW QUESTION # 82
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: A
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 # 83
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?
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 # 84
Northern Trail Outfitters needs a synchronous callout from Salesforce to an Order Management System (OMS) when an opportunity is "Closed/Won" with products attached. What should an integration architect do to satisfy these requirements?
Answer: A
Explanation:
To satisfy a requirement for a synchronous callout triggered by a user action, the architect should use a UI-driven approach, such as a Lightning component and a button.
In Salesforce, triggers (Option B) are primarily used for asynchronous logic in integration contexts. Because a trigger executes as part of the database save operation, making a synchronous callout directly from a trigger is prohibited as it would block the database transaction until the external system responds, leading to performance degradation and "uncommitted work pending" errors. If a trigger must initiate an integration, it must do so asynchronously (using @future or Queueable Apex), which violates the requirement for a synchronous call.
By using a Lightning component, the architect can initiate a synchronous Request-and-Reply pattern. When the sales rep clicks the "7Submit to OMS" button, the componen8t invokes an Apex method that makes the REST callout to the OMS in real-time. The user remains on the page while the system waits for the OMS to respond, allowing for immediate feedback-such as an order confirmation number or an error message-to be displayed in the UI. A Batch Apex job (Option C) is inherently asynchronous and delayed, making it unsuitable for a synchronous, real-time fulfillment requirement.
NEW QUESTION # 85
A customer is migrating from an old legacy system to Salesforce. As part of the modernization effort, the customer would like to integrate all existing systems that currently work with its legacy application with Salesforce. Which constraint/pain-point should an integration architect consider when choosing the integration pattern/mechanism?
Answer: B
Explanation:
When migrating from a legacy landscape to a modern platform like Salesforce, the most immediate technical hurdle is the diversity of system types and communication protocols used by the existing systems.
In a legacy environment, integrations are often not standardized. An architect may encounter systems that communicate via modern REST/SOAP APIs, but they will also likely find older systems that rely on Flat File exchanges (FTP/SFTP), Email-based triggers, or direct Database connections. These "System Types" are a fundamental constraint because they dictate the choice of integration middleware. For example, Salesforce cannot natively poll a file system or read an on-premise database; therefore, an architect must identify these constraints to justify the need for an ETL or ESB tool that can bridge these legacy protocols with Salesforce's API-centric architecture.
While reporting (Option B) and multi-currency (Option C) are important functional requirements for the Salesforce implementation, they do not dictate the integration pattern (e.g., Request-Reply vs. Batch) as much as the technical interface of the source/target systems does. By evaluating the APIs, file systems, and email capabilities of the legacy landscape first, the architect ensures that the chosen integration mechanism-whether it be the Streaming API, Bulk API, or middleware orchestration-is technically capable of actually communicating with the legacy debt.
