Salesforce Integration-Architect Exam Dumps - Actual Questions Answers

When migrating from a legacy landscape to a modern platform like Salesforce, the most immediate technical hurdle is the diversity of system types and communication protocols used by the existing systems.

In a legacy environment, integrations are often not standardized. An architect may encounter systems that communicate via modern REST/SOAP APIs, but they will also likely find older systems that rely on Flat File exchanges (FTP/SFTP), Email-based triggers, or direct Database connections. These "System Types" are a fundamental constraint because they dictate the choice of integration middleware. For example, Salesforce cannot natively poll a file system or read an on-premise database; therefore, an architect must identify these constraints to justify the need for an ETL or ESB tool that can bridge these legacy protocols with Salesforce’s API-centric architecture.

While reporting (Option B) and multi-currency (Option C) are important functional requirements for the Salesforce implementation, they do not dictate the integration pattern (e.g., Request-Reply vs. Batch) as much as the technical interface of the source/target systems does. By evaluating the APIs, file systems, and email capabilities of the legacy landscape first, the architect ensures that the chosen integration mechanism—whether it be the Streaming API, Bulk API, or middleware orchestration—is technically capable of actually communicating with the legacy debt.

When building a distributable package (likely a Managed Package) that must securely communicate back to a central "Hub" org, the architect must use a framework that supports OAuth 2.0 flows. Storing plain-text or even encrypted passwords (Option B) is a security violation and is brittle across different environments.

The architecturally sound solution is to leverage the Authentication Provider and Named Credentials framework. In the central org, a Connected App is created to act as the OAuth endpoint. In the package, an Authentication Provider is configured using the Consumer Key and Consumer Secret from that Connected App. This setup allows the administrator in the "Subscriber" org (the org where the package is installed) to initiate an OAuth flow.

When the security team "authorizes" the integration after installation, they are essentially completing the OAuth handshake. This grants the subscriber org an Access Token and a Refresh Token associated with the specific integration user in the central org. This mechanism ensures:

Credential Security: No passwords are ever stored in the code or metadata.

Centralized Control: The security team in the central org can revoke the Refresh Token at any time to kill the integration.

Scalability: The same package can be distributed to hundreds of orgs, each with its own unique, secure connection to the central Hub.

By using an Authentication Provider combined with a Named Credential, the Apex code in the package can simply call the endpoint by its developer name, and Salesforce handles the entire authentication header injection automatically, ensuring a robust and secure cross-org integration.

Managing identity across a global enterprise with diverse user personas (Employees, Customers, Partners) requires a centralized Identity and Access Management (IAM) strategy. In a landscape involving multiple local Active Directories, social logins (Google), and a central ERP system, attempting to manage authentication natively within Salesforce or through custom-built local silos would result in high technical debt and security vulnerabilities.

The architect should recommend a third-party Single Sign-On (SSO) solution, acting as a central Identity Provider (IdP). This IdP serves as the orchestration layer for all authentication requests.

For Internal Users: The IdP can federate with the various local Active Directories, allowing users to log in with their existing corporate credentials.

For Customers: The IdP can handle "Social Sign-On" (OpenID Connect) with Google and manage self-registration.

For Partners: It provides the "central system" required for their authentication.

By using a central SSO solution, Salesforce acts as a Service Provider (SP). When a user attempts to access Salesforce, the request is redirected to the IdP via the SAML 2.0 or OpenID Connect protocol. Once the IdP validates the user against the appropriate backend (AD, Google, or its own directory), it sends a secure assertion back to Salesforce to grant access.

Furthermore, this central IdP can facilitate access to the ERP system and other internal systems. If these systems support SAML, the same SSO session used for Salesforce can be extended to them, providing a true single sign-on experience. This architecture centralizes security auditing, simplifies user de-provisioning (the "kill switch" effect), and ensures a consistent user experience across the global manufacturing landscape. Implementing a thir2d-party IdP is the industry-standard approach for complex integrations where security, scalabi3lity, and multi-protocol support are primary requirements.
