NEW QUESTION # 85
A new Salesforce program has the following high-level abstract requirement: Business processes executed on Salesforce require data updates between their internal systems and Salesforce. Which relevant detail should an integration architect seek to specifically solve for integration architecture needs of the program?
Answer: C
Explanation:
In the discovery and translation phase of a Salesforce project, an Integration Architect must move beyond high-level business goals to define the technical "DNA" of the data exchange. While organizational readiness and user experience are vital to project success, they do not dictate the architectural patterns required to move data between systems.
The most critical details for designing an integration architecture are the Timing and Volume requirements. Identifying whether a business process is Synchronous or Asynchronous is the primary decision point. For example, if a Salesforce user requires an immediate validation from an external system before they can save a record, a synchronous "Request-Reply" pattern using an Apex Callout is required. If the data update can happen in the background without blocking the user, an asynchronous "Fire-and-Forget" pattern is preferred to improve system performance and user experience.
Furthermore, understanding the Update Frequency (e.g., real-time, hourly, or nightly) and the Data Volume (e.g., 100 records vs. 1 million records) allows the architect to select the appropriate Salesforce API. High-volume, low-frequency updates are best handled by the Bulk API to minimize API limit consumption, while low-volume, high-frequency updates are better suited for the REST API or Streaming API. By specifically seeking out these timing and frequency aspects, the architect ensures that the chosen solution is scalable, stays within platform governor limits, and meets the business's Service Level Agreements (SLAs). Without these details, the architect risks designing a solution that is either too slow for the business needs or too taxing on system resources.
NEW QUESTION # 86
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 # 87
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?
Answer: B
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 # 88
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: B
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.
NEW QUESTION # 89
A subscription-based media company's system landscape forces many subscribers to maintain multiple accounts and to log in more than once. An Identity and Access Management (IAM) system, which supports SAML and OpenID, was recently implemented to improve the subscriber experience through self-registration and single sign-on (SSO). The IAM system must integrate with Salesforce to give new self-service customers instant access to Salesforce Community Cloud.
Answer: C
Explanation:
To provide "instant access" and a seamless experience for Community (Experience Cloud) users, the architect must choose an authentication and provisioning strategy that handles user creation on-the-fly. While both SAML and OpenID Connect (OIDC) are viable for SSO, OpenID Connect is the modern standard for consumer-facing "Social" or external identity integrations because it is built on OAuth 2.0.
The critical component for "self-service" is the Registration Handler. When an OpenID Connect Authentication Provider is configured in Salesforce, you must associate it with an Apex class that implements the Auth.RegistrationHandler interface. This handler is executed during the SSO flow if the user does not already exist. It provides the architect with full programmatic control to:
Match the incoming identity to an existing Contact or Account.
Create a new Contact record if one doesn't exist.
Provision a new User record with the correct Profile, Permission Sets, and Locale settings.
Link the User to the correct Account hierarchy, which is vital for Community security models.
Option A suggests Just-in-Time (JIT) provisioning, which is a declarative way to create users. However, JIT is often too rigid for Experience Cloud requirements, as it has limited ability to perform complex data lookups or handle the specific linking of Contacts to Accounts required for external users. Option C is technically mismatched in common Salesforce terminology; while SAML uses JIT, the Registration Handler is the native, specific mechanism designed to work with Authentication Providers (like OIDC). By using B, the company ensures that a subscriber logging in for the first time via the IAM system is instantly and accurately provisioned in Salesforce, eliminating the need for multiple accounts.
