NEW QUESTION # 88
An enterprise customer with more than 10 million customers has a landscape including an Enterprise Billing System (EBS), a Document Management System (DMS), and Salesforce CRM. Customer Support needs seamless access to customer billing information from the EBS and generated bills from the DMS. Which authorization and authentication need should an integration consultant consider while integrating the DMS and EBS with Salesforce?
Answer: B
Explanation:
When integrating Salesforce with high-security enterprise systems like an Enterprise Billing System (EBS) and a Document Management System (DMS), the primary architectural concern is respecting the Enterprise security needs for access control. These systems often contain highly sensitive financial data and are governed by strict regulatory requirements (e.g., PCI-DSS or GDPR).
The integration consultant must evaluate how to extend existing enterprise identity and authorization policies to Salesforce users. This often involves a Identity Federation strategy using protocols like SAML 2.0 or OpenID Connect. Instead of maintaining separate credentials in Salesforce (which Option A suggests and is generally an "anti-pattern" for 10 million records), the consultant should consider using a central Identity Provider (IdP).
By considering enterprise security needs, the architect ensures that when a support agent clicks a link in Salesforce to view a bill, the request is authenticated against the enterprise's security gateway. This allows for Single Sign-On (SSO) while ensuring that authorization (who can see what) remains mastered in the source systems or the central IdP. Migration (Option C) is physically and technically unfeasible for systems handling 10 million customers' historical bills and real-time processing. The focused objective is to build a "window" into these systems from Salesforce while maintaining the integrity of the enterprise's existing security perimeter.
NEW QUESTION # 89
A company has an external system that processes and tracks orders. Sales reps manage their leads and opportunity pipeline in Salesforce. The company decided to integrate Salesforce and the Order Management System (OMS) with minimal customization and code. Sales reps need to see order history in real-time. The legacy system is on-premise and connected to an ESB. There are 1,000 reps creating 15 orders each per shift, mostly with 20-30 line items. How should an integration architect integrate the two systems based on these requirements?
Answer: B
Explanation:
To meet the requirements of minimal customization, low developer resources, and real-time visibility without data replication, the architect should utilize Salesforce Connect with External Objects and an OData connector.
Salesforce External Objects allow the OMS data to be viewed within Salesforce as if it were stored natively, but the data remains in the on-premise system. This fulfills the requirement for sales reps to see "up-to-date information" because every time they view the record, Salesforce Connect fetches the latest data via the ESB's OData endpoint. This Data Virtualization pattern is the most efficient choice for real-time history where users only need to view the data occasionally.
Options A and B involve Data Replication via ETL, which would store the order data inside Salesforce. Given the volume (15,000 orders/shift with 25 line items each = 375,000 records daily), this would rapidly consume Salesforce data storage limits and require significant custom development for the ETL logic and REST APIs. Furthermore, ETL is typically batch-oriented and would not provide the true "real-time" view requested. By using an OData connector, the architect leverages a declarative, "no-code" solution that satisfies the timeline constraints and provides immediate access to order details and line items without the cost of data storage.
NEW QUESTION # 90
Salesforce users need to read data from an external system via an HTTP request. Which security methods should an integration architect leverage within Salesforce to secure the integration?
Answer: C
Explanation:
To secure outbound HTTP requests from Salesforce, architects must implement defense-in-depth measures at both the authentication and transport layers.
Named Credentials are the primary architectural recommendation for managing callout endpoints and authentication in a secure, declarative manner. They abstract the endpoint URL and authentication parameters (such as usernames, passwords, or OAuth tokens) away from Apex code. This prevents sensitive credentials from being hardcoded or exposed in metadata, significantly reducing the risk of accidental disclosure. By using Named Credentials, Salesforce handles the heavy lifting of authentication headers automatically, ensuring that the integration is both secure and maintainable.
Two-way SSL (Mutual Authentication) provides an additional layer of security at the transport layer. While standard SSL ensures that Salesforce trusts the external server, Two-way SSL requires the external server to also verify the identity of the Salesforce client. The architect first generates a certificate in Salesforce, which is then presented to the external system during the TLS handshake. This "mutual trust" ensures that the external service only accepts requests from an authorized Salesforce instance, protecting against man-in-the-middle attacks and unauthorized access attempts.
While an Authorization Provider (Option C) is essential for OAuth-based flows, it is typically used within the configuration of a Named Credential rather than as a standalone security method for a generic HTTP request. By combining Named Credentials with Two-way SSL, the architect ensures that the integration is secured at both the session/authentication level and the network/transport level, adhering to enterprise security best practices for cloud-to-on-premise or cloud-to-cloud communication.
NEW QUESTION # 91
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: C
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 # 92
Universal Containers (UC) is currently managing a custom monolithic web service that runs on an on-premise server. This monolithic web service is responsible for Point-to-Point (P2P) integrations between Salesforce and a legacy billing application, a cloud-based ERP, and a data lake. UC has found that the tight interdependencies are causing failures. What should an integration architect recommend to decouple the systems and improve performance?
Answer: C
Explanation:
The primary architectural flaw in UC's current landscape is the reliance on a monolithic P2P integration layer. In such designs, any failure in one integration thread or a surge in volume for one system can monopolize resources (CPU, memory, threads), causing the entire service-and thus all other integrations-to fail. This lack of isolation leads to the "tight interdependencies" described.
To effectively decouple these systems, the architect should recommend a Microservices Architecture. By breaking the monolithic service into smaller, independent, and modular components, each integration (Billing, ERP, Data Lake) becomes its own isolated service. This approach provides several key architectural benefits:
Isolation of Failure: If the connection to the legacy billing application fails or times out, it no longer impacts the ERP or Data Lake integrations.
Independent Scalability: If the Data Lake integration requires high throughput, that specific microservice can be scaled horizontally without wasting resources on the others.
Technology Agility: Each microservice can be updated or patched independently, allowing for faster maintenance cycles.
Furthermore, moving a "monolithic" service to the cloud (Option B) is simply a "lift and shift" that preserves the underlying fragility. While the Bulk API (Option A) is excellent for high-volume data loading, it does not solve the fundamental problem of system interdependency and orchestration failure. Transitioning to a modular, service-oriented design allows UC to implement modern integration patterns, such as asynchronous queuing between the microservices, which significantly improves the overall resilience and performance of the Salesforce-to-back-office landscape.
