NEW QUESTION # 127
An integration architect has built a solution using REST API, updating Account, Contact, and other related information. The data volumes have increased, resulting in higher API calls consumed, and some days the limits are exceeded. A decision was made to decrease the number of API calls using bulk updates. The customer prefers to continue using REST API to avoid architecture changes. Which REST API composite resources should the integration architect use to allow up to 200 records in one API call?
Answer: A
Explanation:
When designing high-volume integrations, the Salesforce Platform Integration Architect must distinguish between standard REST resources and "Composite" resources to optimize API consumption. The Salesforce REST API provides several composite resources to group multiple operations into a single call, thereby reducing the overhead of multiple HTTP requests and helping to stay within daily API limits.
According to Salesforce documentation on Composite Resources, the sObject Tree resource (/services/data/vXX.X/composite/tree/) is specifically designed to handle multiple records in a single request. While it is primarily marketed for creating complex hierarchies (parent-child relationships), it has a unique limit that allows for up to 200 records to be processed in a single call. These records can even be unrelated records of the same type. This is a significant advantage over the standard Batch and Composite resources.
The Composite resource and the Batch resource both have a much lower limit of 25 subrequests per call. While each subrequest in a Batch call could technically be a collection operation, the question specifically asks for the resource that natively supports the "200 records" threshold preferred for bulk-style updates within the REST framework. By utilizing the sObject Tree resource, the architect can bundle 200 record updates into a single transaction, effectively reducing API consumption by a factor of 200 compared to individual REST calls. This aligns with the requirement to avoid major architectural changes (like switching to the Bulk API 2.0) while solving the immediate problem of exceeding daily governor limits. In the context of the Integration Architect exam, understanding these specific payload limits is crucial for selecting the most efficient "Request-Reply" or "Data Synchronization" pattern.
NEW QUESTION # 128
A business requires automating the check and updating of the phone number type classification (mobile vs. landline) for all incoming calls delivered to its phone sales agents. The following conditions exist:
At peak, the call center can receive up to 100,000 calls per day.
The phone number type classification is a service provided by an external service API.
Business is flexible with timing and frequency to check and update the records (throughout the night or every 6-12 hours is sufficient).
A Remote-Call-In pattern and/or Batch Synchronization (Replication via ETL: System -> Salesforce) are determined to work with a middleware hosted on customer premise. In order to implement these patterns and mechanisms, which component should an integration architect recommend?
Answer: B
Explanation:
In this scenario, the architecture involves a Remote-Call-In pattern or Batch Synchronization, where an external system (the middleware or ETL tool) initiates communication with Salesforce to update records. For any external system to securely access Salesforce APIs and perform these updates, it must be authenticated and authorized.
The Connected App is the foundational framework that allows an external application to integrate with Salesforce using APIs and standard protocols, such as OAuth 2.0 and SAML. By configuring a Connected App, the architect can define which permissions (Scopes) the middleware has, such as the ability to access data via the REST or Bulk API. This is the correct choice because the middleware needs to "log in" to Salesforce to push the phone classification data back into the Account or Contact records.
Option B, an API Gateway, is typically used to manage and secure requests going out of an organization to external services, or to provide a facade for on-premise APIs; it does not handle the inbound authentication into Salesforce itself. Option C, Remote Site Settings, is a configuration used solely to permit Salesforce to make outbound calls to a specific external URL (for example, if Salesforce were calling the phone classification service directly via Apex).
Given that the business is flexible with timing (allowing for nightly or 12-hour syncs) and handles 100,000 calls, a Batch Synchronization pattern via an ETL tool is highly efficient. The ETL tool will authenticate against the Connected App using a secure OAuth flow (such as the JWT Bearer Flow for server-to-server integration), retrieve the new phone numbers, call the external classification API, and then bulk-update the Salesforce records. This setup ensures a secure, scalable, and manageable integration that respects Salesforce's security architecture while meeting the high-volume data requirements of the call center.
NEW QUESTION # 129
Northern Trail Outfitters (NTO) is planning to create a native employee-facing mobile app with the look and feel of Salesforce Lighting Experience. The mobile app needs to integrate with NTO's Salesforce org. Which Salesforce API should be used to implement this integration?
Answer: C
Explanation:
When building custom mobile or web applications that aim to replicate the look and feel of Salesforce Lightning Experience, the User Interface (UI) API is the architecturally recommended choice.
The UI API is specifically designed to provide the metadata and data needed to build high-fidelity user interfaces. Unlike the standard REST API (Option B), which returns raw record data, the UI API returns both data and metadata in a single response. This includes information about page layouts, field-level security, picklist values, and localized labels. By using the UI API, the mobile app can dynamically render fields according to the user's permissions and the organization's layout configurations, ensuring that the custom app stays in sync with changes made in Salesforce Setup without requiring code updates in the mobile app.
Connect REST API (Option A) is primarily used for Chatter, Communities (Experience Cloud), and CMS content, and while it is useful for those specific social features, it does not provide the layout and record-level metadata required for a full CRM interface. The UI API is the same underlying technology that powers the Salesforce mobile app and Lightning Experience itself. Therefore, utilizing this API allows NTO's developers to build a native app that perfectly mimics the Lightning Experience while reducing the amount of custom logic needed to handle complex Salesforce UI requirements.
NEW QUESTION # 130
What should an integration architect recommend to ensure all integrations to the Northern Trail Outfitters' company portal use SSL mutual authentication?
Answer: B
Explanation:
To ensure that all integrations calling into a Salesforce portal are secured with Mutual Authentication, the architect must enable and configure specific platform-level security settings. The primary recommendation is to Enforce SSL/TLS Mutual Authentication for the relevant integration users.
Mutual Authentication (Two-way SSL) adds a layer of trust beyond the standard session-based authentication. When enforced, the Salesforce server requires the calling client to present a valid CA-signed certificate that matches a certificate stored in the org. This ensures that only authorized systems with the correct private key can establish a connection.
To implement this, the architect must first work with Salesforce support to enable the feature. Once enabled, a Mutual Authentication Certificate must be uploaded to the org, and a specific user profile-cloned for integration purposes-must have the "Enforce SSL/TLS Mutual Authentication" permission enabled. This configuration forces the client to use port 8443 (the dedicated port for mutual TLS) for API calls, providing a highly secure, server-to-server connection that protects against impersonation and unauthorized data access.
NEW QUESTION # 131
A media company recently implemented an IAM system supporting SAML and OpenId. The IAM system must integrate with Salesforce to give new self-service customers instant access to Salesforce Community Cloud. Which requirement should Salesforce Community Cloud support for self-registration and SSO?
Answer: A
Explanation:
To provide "instant access" for new customers via an external IAM system using SAML, Salesforce provides a declarative feature called Just-in-Time (JIT) provisioning.
When a customer attempts to log in to the Community (Experience Cloud) through the IAM system, the IAM system (acting as the Identity Provider) sends a SAML assertion to Salesforce. If JIT provisioning is enabled, Salesforce parses the user information contained in that assertion-such as name, email, and federation ID. If a corresponding User record does not exist, Salesforce automatically creates one on-the-fly and then logs the user in. This eliminates the need for a manual registration step or pre-provisioning accounts.
Option A is slightly incorrect because Registration Handlers are specifically associated with Authentication Providers (which use OpenID Connect/OAuth), not SAML SSO. Option C is incorrect because JIT provisioning is a feature of SAML, while Authentication Providers use the Registration Handler class to achieve the same result. For a "self-service" scenario where speed to market and standard protocols are key, SAML SSO with JIT provisioning is the architect's primary choice for automating user management and providing a seamless single-entry point for subscribers.
