Salesforce Identity-and-Access-Management-Architect - Salesforce Certified Platform Identity and Access Management Architect (Plat-Arch-203)

To have users provisioned via a service endpoint before users access their app from Salesforce, the identity architect should recommend using a connected app with user provisioning flow. A connected app is a framework thatenables an external application to integrate with Salesforce using APIs and standard protocols. A user provisioning flow is a custom post-authentication process that can be used to create or update users in the external application using a service endpoint when users access the connected app from Salesforce. This approach can provide automatic user provisioning with limited changes to the third-party app. References: Connected Apps, User Provisioning for Connected Apps

Theweb server flow is used for web applications when server-side code needs to interact with APIs. This flow implements the OAuth 2.0 authorization code grant type, which allows the web app to obtain an access token and a refresh token from Salesforce after theuser grants permission1. The web app can then use the access token to call the Salesforce APIs and use the refresh token to obtain a new access token when the previous one expires2. The other options are not valid scenarios for using the web server flow. The webserver flow is not used for server-side components when page needs to be rendered, as this does not involve API calls. The web server flow is not used for mobile applications and testing legacy integrations, as these scenarios are better suited for other OAuthflows, such as theuser-agent flow or the password flow3. The web server flow is not used for verifying access protected resources, as this is a general purpose of OAuth, not a specific scenario for the web server flow.
