質問 # 55
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?
正解：B
解説：
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.

An integration developer is developing an HR synchronization app for a client. The app synchronizes Salesforce record data changes with an HR system that's external to Salesforce. What should the integration architect recommend to ensure notifications are stored for up to 3 days if data replication fails?
正解：C
解説：
For HR synchronization requiring high reliability and a multi-day data retention window, Change Data Capture (CDC) is the optimal architectural choice.12 CDC is an event-driven integration framework that automatically publ3ishes change events for Sale4sforce records (Create, Update, Delete, and Undelete). A critical feature of CDC for failure recovery is its 72-hour (3-day) retention window. If the external HR system or the replication middleware experience downtime, the change events remain stored in the Salesforce event bus for up to three days. Once the HR system is back online, the subscriber can use the Replay ID of the last successfully processed event to retrieve all missed notifications from the bus, ensuring zero data loss during the outage.
In contrast, Outbound Messaging (Option B) only provides a 24-hour retry window. If the target system is unavailable for more than one day, the notifications are dropped, making it unsuitable for a 3-day requirement. Callouts (Option C) are typically synchronous and do not have native, platform-managed storage or retry mechanisms for failed requests; once a callout fails, the data is lost unless a custom retry architecture is built. CDC's native, durable event bus provides the necessary scalability and resilience for critical HR data synchronization without requiring complex custom code for error handling and data recovery.

Universal Containers (UC) support agents would like to open bank accounts on the spot. During the process, agents execute credit checks through external agencies. At any given time, up to 30 concurrent reps will be using the service. Which error handling mechanisms should be built to display an error to the agent when the credit verification process has failed?
正解：B
解説：
In a synchronous Request-Reply scenario where a bank agent is waiting "on the spot" for a credit check, the error-handling strategy must balance immediate feedback with system resilience.
Option A is the recommended architectural approach for enterprise resiliency. By placing a Middleware layer (like MuleSoft) between Salesforce and the credit agencies, the architect can implement sophisticated error-handling patterns that are invisible to the user but critical for success. If a credit agency's API is momentarily unreachable, the middleware can perform automated retries (e.g., three attempts with 500ms intervals). If the retries still fail, the middleware sends a clean, structured error response back to Salesforce.
Option B (Fire and Forget) is fundamentally unsuitable for this use case because the agent needs the result immediately to open the account; they cannot wait for a callback that might arrive hours later. Option C (Mock service) is only a testing tool and provides no value in a production environment where real financial data is required. By delegating the retry logic to the middleware, the architect protects Salesforce's concurrent request limits (since the agent only occupies a thread for the duration of the final response) and ensures that transient network issues do not result in a "failed" bank account application for the customer.

Northern Trail Outfitters (NTO) has recently changed its Corporate Security Guidelines. The guidelines require that all cloud applications pass through a secure firewall before accessing on-premise resources. NTO is evaluating middleware solutions to integrate cloud applications with on-premise resources and services. Which consideration should an integration architect evaluate before choosing a middleware solution?
正解：C
解説：
When corporate guidelines mandate that all cloud-to-on-premise traffic must pass through a secure firewall, the architecture must support a Demilitarized Zone (DMZ) or "Perimeter Network" strategy. The Integration Architect must evaluate whether the middleware solution includes a robust API Gateway component.
A secure API Gateway acts as the single entry point for all external requests. It is typically deployed within the DMZ to terminate incoming TLS connections from the cloud (Salesforce) and perform deep packet inspection, IP whitelisting, and authentication before proxying the request to internal on-premise resources. This provides a critical layer of insulation, ensuring that internal services-such as an ERP or legacy database-are never exposed directly to the public internet.
While OAuth enforcement (Option B) is a common requirement for authorization, it does not fulfill the specific network-level firewall requirement described. Similarly, ODBC connectivity (Option C) is a low-level internal database protocol that should generally be avoided for cross-firewall communication due to its inherent security risks. By selecting a middleware solution with integrated API Gateway capabilities, Northern Trail Outfitters can provide the security team with centralized control over encryption, rate limiting, and threat protection, thereby strictly adhering to the new Corporate Security Guidelines while enabling seamless hybrid cloud integration.
質問 # 59
A company that is a leading provider of courses and training delivers courses using third-party trainers. The trainer for the company has to be verified by 10 different training accreditation verification agencies before providing training for the company. Each training accreditation agency has its own response time, which means it could take days to confirm a trainer. The company decided to automate the trainer accreditation verification process by integrating it with the agency's web service1s. What is the recommended approach to automa2te this process?3456
正解：A
解説：
In this scenario, the primary architectural challenge is managing high-latency, multi-step orchestration involving 10 disparate external systems. Each agency has a varying response time that can span several days, making a synchronous "Request-Reply" pattern within Salesforce technically impossible due to transaction timeout limits (maximum 120 seconds).
The recommended approach is to leverage Middleware as the orchestration and state-management layer. Middleware (such as an ESB or iPaaS) is specifically designed for Process Choreography. Salesforce initiates a single "Fire and Forget" request to the middleware. The middleware then takes responsibility for:
Sequential or Parallel Callouts: Initiating the requests to all 10 verification agencies.
Callback Management: Handling the asynchronous responses from each agency as they arrive over a period of days.
Aggregation Logic: Consolidating the results and determining when the "Business Process" is complete (e.g., all 10 agencies have approved).
Once the consolidation logic is satisfied, the middleware performs a Remote Call-In to the Salesforce REST API to update the trainer's record. This pattern keeps Salesforce "clean" by moving complex, long-running orchestration logic off-platform, preventing the consumption of excessive Apex CPU time and ensuring that Salesforce only receives a single, final status update.
Option B (External Services) is unsuitable for a multi-day asynchronous process as it is designed for real-time, synchronous Flow actions. Option C (@future) is restricted by the same 120-second timeout and cannot handle the "waiting" state required for days of verification. Using middleware provides the necessary Quality of Service (QoS), durability, and error handling required for such a critical enterprise compliance process.
