NEW QUESTION # 124
What is the first thing an integration architect should validate if a callout from a Lightning web component (LWC) to an external endpoint is failing?
Answer: B
Explanation:
When an integration initiated from the client-side (the browser) fails, the architect must first look at the browser's security policies. In Salesforce, Lightning Web Components are subject to the Lightning Component framework's Content Security Policy (CSP).
CSP is a security layer that prevents cross-site scripting (XSS) and other code injection attacks by restricting which domains the browser is allowed to communicate with. If an LWC attempts to make a fetch() call to an external REST endpoint, the browser will block the request unless that specific domain is whitelisted in CSP Trusted Sites.
Option B (Remote Site Settings) is a common distractor; these settings are strictly for server-side Apex callouts and have no effect on client-side JavaScript requests. Option A (CORS) is also a browser security mechanism, but it must be configured on the external server to allow Salesforce to access its resources. While CORS is necessary, the first thing to validate within the Salesforce environment for a failing LWC callout is the CSP Trusted Site entry. Without this whitelisting, the request will be terminated by the browser before it even leaves the client, regardless of how the external server is configured.
NEW QUESTION # 125
Universal Containers (UC) uses Salesforce Service Cloud. Support agents open bank accounts on the spot. UC's core banking system is the system of record, and all accounts opened in Salesforce must be synced in real time. Agents need to inform the customers of the newly created bank account ID, which is generated by the core banking system. Which integration pattern is recommended for this use case?
Answer: C
Explanation:
The requirement for an agent to receive a newly created bank account ID in real time to inform a customer signifies a synchronous dependency. The agent cannot complete the business process until the core banking system confirms the account creation and returns the generated identifier.
The Request and Reply pattern is the appropriate recommendation for this use case. In this pattern:
Request: Salesforce sends a synchronous callout (REST or SOAP) containing the customer's data to the core banking system.
Wait: The Salesforce thread remains open, and the user interface typically displays a loading indicator while waiting for the external system to process the request.
Reply: The core banking system returns the new account ID, which is then immediately displayed to the support agent in Salesforce.
Options A (Platform Events) and C (Streaming API) are asynchronous, event-driven patterns. While highly scalable, they are unsuitable for this specific "on the spot" requirement because there is no native way to force the agent's screen to wait for an asynchronous callback with the new ID. Request and Reply ensures that the agent has the necessary information to complete the customer interaction in a single, continuous flow.
NEW QUESTION # 126
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?
Answer: A
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
NEW QUESTION # 127
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: C
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 # 128
Northern Trail Outfitters (NTO) has a requirement to encrypt a few widely-used standard fields. NTO also wants to be able to use these fields in record-triggered flows.
Which security solution should an integration architect recommend to fulfill the business use case?
Answer: C
Explanation:
To satisfy the requirement of encrypting standard fields while maintaining their functionality within record-triggered flows, Shield Platform Encryption is the recommended architectural solution.1 Shield Platform Encryption is a modern security layer that allows for encryption at rest while 2preserving critical platform features. Unlike Classic Encryption (Option B)-which is limited to a specific "Encrypted Text" custom field type and often breaks platform features like search and automation-Shield is designed to work with standard fields such as Name, Email, and Phone.
Key architectural considerations for Shield include:
Compatibility with Automation: Shield fields can be used in Flows, Apex triggers, and validation rules. This allows NTO to implement the required record-triggered business logic without needing to decrypt the data manually in code.
Search and Filtering: By using Deterministic Encryption, Shield allows users to filter and search for records based on encrypted fields, which is often a requirement for "widely-used" standard fields.
Compliance and Governance: Shield provides advanced key management (Bring Your Own Key - BYOK) and auditing, ensuring that NTO meets corporate security guidelines while data is being processed by the platform.
Data Masking (Option C) is primarily used for sandboxes to obfuscate PII during testing and is not a production encryption-at-rest solution. By recommending Shield, the architect provides a transparent security model that protects sensitive data without sacrificing the declarative power of Flow Builder.
