NEW QUESTION # 114
A customer's enterprise architect has identified requirements around caching, queuing, error handling, alerts, retries, event handling, etc. The company has asked the integration architect to help fulfill such aspects with its Salesforce program. Which recommendation should the integration architect make?
Answer: C
Explanation:
Salesforce is a highly capable CRM platform, but it is not a dedicated messaging or orchestration engine.
When requirements include complex message queuing, process choreography, and guaranteed quality of service (QoS), the Integration Architect must recommend a middleware solution (ESB or iPaaS).
"True message queuing" involves holding messages in a persistent state until the target system is ready to receive them, handling sophisticated retry logic (such as exponential backoff), and providing dead-letter queues for failed messages. While Salesforce has basic asynchronous tools like Outbound Messaging or Platform Events, they lack the granular control over queuing and orchestration that enterprise middleware provides.
Option A is incorrect because performing heavy transformation and protocol translation (like XML to JSON or SOAP to REST) within Salesforce consumes excessive Apex CPU time and is better handled by middleware designed for that purpose. Option B is conceptually backward; usually, architects move away from synchronous Request-Reply toward asynchronous Fire-and-Forget to improve scalability. By recommending a middleware solution to handle these infrastructure-level concerns, the architect ensures that Salesforce remains performant for its users while the middleware manages the technical complexities of reliably connecting the enterprise.
NEW QUESTION # 115
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.
* However, their current response times could take up to 90 seconds to process and return (there are discussions to reduce the response times in the future, but no commitments are made).
* These eligibility systems can be accessed through APIs orchestrated via ESB (MuleSoft).
* All requests from Salesforce will have to traverse through the customer's API Gateway layer, and the API Gateway imposes a constraint of timing out requests after 9 seconds.
Which recommendation should the integration architect make?
Answer: A
Explanation:
The primary architectural challenge in this scenario is the massive discrepancy between the backend response time (up to 90 seconds) and the API Gateway timeout constraint (9 seconds). In any synchronous integration pattern, the connection must remain open across the entire path; if the API Gateway closes the connection at 9 seconds, a standard Salesforce "Request-Reply" callout will fail long before the 90-second eligibility check is complete.
Option A is non-viable because synchronous polling at a high scale (3,000 concurrent users) would likely hit Salesforce concurrent request limits and place an immense, unnecessary load on the API Gateway. Option B, using Continuation, is designed to handle long-running callouts (up to 120 seconds) without blocking Salesforce threads, but it still requires the external connection path to remain open. It does not bypass the 9- second timeout imposed by the customer's API Gateway.
The optimal recommendation is Option C, which implements an Asynchronous Request-Reply pattern using Platform Events and the empAPI.12
* Request Phase: The Salesforce UI initiates the request. To bypass the 9-second gateway timeout, the ESB (MuleSoft) should be configured to receive the request3 and immediately return an acknowledgment (e.g.,4 HTTP 202 Accepted). This allows the initial Salesforce callout to complete successfully within the 9-second window.56
* Processing Phase: MuleSoft then proceeds with the long-running (up to 90 seconds) call to the external eligibility systems.78
* Callback Phase (Remote Call-In)9: Once the eligibility result is received, MuleSoft calls back into Salesforce via the REST API to publish a Platform Event containing the result.10
* UI Update (empA11PI): The 3,000 sales agents' browsers, having subscribed to the event channel using the empAPI (Lightning's built-in library for streaming events), receive the notification in real- time. The UI then updates to display the "Display Response" step.
This event-driven architecture effectively "insulates" Salesforce and the API Gateway from the backend's high latency, ensures scalability for 3,000 concurrent users, and provides a seamless, real-time user experience without hitting governor limits or timeout constraints.
NEW QUESTION # 116
When user clicks Check Preferences as part of a Lightning flow in Salesforce, preferences from anexternally hosted RESTful service are to be checked in real-time. The RESTful service has OpenAPI 2.0 JSON definitions, responding in data types of Boolean and string values.
Which integration pattern and mechanism should be selected to meet the conditions?
Answer: C
Explanation:
The correct answer is C, Request-Reply: Enhanced External Services invokes a REST API. This is because Enhanced External Services allows you to register an external web servicethat has an OpenAPI 2.0 specification and use it as an invocable action in a Lightning flow. This way, you can check the preferences from the external service in real-time and get the response in Boolean and string values. The other options are not suitable for this scenario because:
A, Fire and Forget: Process-driven platform events publishes events on Salesforce Event Bus, is a pattern that is used for asynchronous integration, where the sender does not expect a response from the receiver. This is not suitable for checking preferences in real-time.
B, Remote Call-In: Salesforce REST API with REST Composite Resources, is a pattern that is used for integrating external applications with Salesforce by calling the Salesforce REST API. This is not suitable forinvoking an external service from a Lightning flow.
D, Data Virtualization: Salesforce Connect map data external REST data in external objects, isa pattern that is used for accessing external data without copying or synchronizing it to Salesforce. This is not suitable for checking preferences in real-time or using them in a Lightning flow.

NEW QUESTION # 117
Universal Containers (UC) is a large printing company that sells advertisement banners. The company works with third-party agents on banner initial design concepts. The design files are stored in an on-premise file store that can be accessed by UC internal users and the third party agencies. UC would like to collaborate with the 3rd part agencies on the design files and allow them to be able to view the design files in the community.
The conceptual design files size is 2.5 GB.
Which solution should an integration architect recommend?
Answer: D

NEW QUESTION # 118
What is the first thing an Integration Architect should validate if a callout from a LightningWeb Component to an external endpoint is failing?
Answer: A
Explanation:
The first thing an integration architect should validate if a callout from a Lightning Web Component to an external endpoint is failing is the endpoint domain has been added to Cross-Origin Resource Sharing (CORS).
CORS is a mechanism that allows web browsers to make requests to servers on different origins, such as different domains, protocols, orports. CORS requires the server to send back a special header that indicates whether the browser is allowed to access the resource or not. If the endpoint domain is not added to the CORS whitelist in Salesforce, the browser will block the callout and throwan error. Option B is not correct because Content Security Policies (CSP) are used to control what resources can be loaded on a Visualforce or Lightning page, such as scripts, stylesheets, images, etc. CSP does not affect the callout from a Lightning WebComponent to an external endpoint. Option C is not correct because outbound firewall rules are used to restrict the network traffic from Salesforce to external systems. Firewall rules are configured at the network level, not at the Salesforce level. OptionD is not correct because Remote Site Settings are used to specify the domains that are allowed for callouts from Apex code, not from Lightning Web Components. References:
