NEW QUESTION # 67
A company needs to integrate a legacy on-premise application that can only support SOAP API. After the integration architect evaluates the requirements and volume, they determine that the Fire and Forget integration pattern will be most appropriate for sending data from Salesforce to the external application and getting response back in a strongly-typed format.
Which integration capabilities should be used to integrate the two systems?
Answer: A
Explanation:
When integrating with a legacy SOAP-only application using a Fire and Forget pattern, Salesforce Outbound Messaging is the native, declarative choice.
Outbound Messaging is a platform feature that sends a SOAP message to a designated endpoint when specific criteria are met. It is inherently asynchronous and provides built-in reliability; if the legacy system is offline, Salesforce will automatically retry the delivery for up to 24 hours. This perfectly fits the "Fire and Forget" requirement.
For the strongly-typed response back (Remote Call-In), the Enterprise WSDL is the correct recommendation.1415 Enterprise WSDL: This is a strongly-typed WSDL generated specifically for one org's metadata. It includes specific references to16 custom objects and fields, ensu17ring that the legacy system can communicate with Salesforce using a rigid, predictable data structure.
Partner WSDL (Option C): This is a loosely-typed WSDL designed for developers building tools that must work across many different orgs; it is not ideal for an internal, strongly-typed legacy integration.
While Platform Events (Option B) are a modern alternative, they typically use REST or Streaming APIs, making them a less natural fit for an application that "can only support SOAP". By combining Outbound Messaging and the Enterprise WSDL, the architect provides a robust, SOAP-native solution that satisfies the business's technical constraints and reliability requirements.
NEW QUESTION # 68
An integration architect has received a request to prevent employees that leave the company from accessing data in Salesforce after they are deactivated in the company's HR system. What should the integration architect determine before recommending a solution?
Answer: C
NEW QUESTION # 69
Northern Trail Outfitters (NTO) has recently changed its Corporate Security Guidelines requiring all cloud applications to pass through a secure firewall before accessing on-premise resources. NTO is evaluating middleware solutions. Which consideration should an integration architect evaluate before choosing a middleware solution?
Answer: C
Explanation:
When corporate guidelines mandate a firewall-protected entry point for cloud traffic, the middleware architecture must include a component capable of residing in a Demilitarized Zone (DMZ) or perimeter network. The architect must evaluate the solution's API Gateway capabilities.
A secure API Gateway acts as the intermediary that terminates external (cloud) TLS connections and inspects incoming traffic before proxying it to internal systems. It allows the security team to implement:
IP Whitelisting: Ensuring only Salesforce's IP ranges can access the gateway.
Mutual Authentication: Using certificates to verify that the request is genuinely coming from the Salesforce org.
Rate Limiting: Protecting on-premise resources from being overwhelmed by cloud requests.
Option A (OAuth) is an authorization framework and does not satisfy the network-level firewall requirement on its own. Option B (ODBC) is an internal database protocol that should generally never be exposed to a cloud-facing firewall due to security risks. By prioritizing a solution with a hardened API Gateway, the architect ensures that NTO meets its new security mandates while providing a scalable and secure bridge for Salesforce to access back-office services.
NEW QUESTION # 70
Northern Trail Outfitters (NTO) wants to improve the quality of callouts from Salesforce to its REST APIs by requiring all API clients to adhere to RAML (REST API Markup Language) specifications. The RAML specs serve as interface contracts. Which design specification should the integration architect include in the integration architecture to ensure that Apex REST API Clients' unit tests confirm adherence to the RAML specs?
Answer: C
Explanation:
In a contract-first integration approach using RAML, the specification acts as the single source of truth for request and response structures. Since Salesforce unit tests are prohibited from performing actual network callouts, the HttpCalloutMock interface must be used to simulate external API behavior.
To ensure unit tests truly confirm adherence to the RAML contract, the architect must mandate that the mock implementation specifically returns responses formatted per the RAML specification. This means the mock's JSON or XML body, headers, and HTTP status codes (e.g., 200 OK, 400 Bad Request) must exactly match the "interface contract" defined in the RAML file.
By strictly aligning the mock with the RAML spec, developers ensure that the Apex client's parsing logic (e.g., JSON.deserialize()) is tested against the agreed-upon data model. If the external service later changes its schema in a way that deviates from the RAML, the unit tests-which are based on that contract-will help identify where the Apex code might fail. Options B and C are technically incorrect: the client does not "call" or "implement" the mock; rather, the test runtime provides the mock instance to the client via Test.setMock().
NEW QUESTION # 71
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.
