The most appropriate license types for GS regional leads and the GS capacity planners are:

Customer Community Plus license for GS regional leads. This license type allows external users, such as customers or partners, to access standard Salesforce objects, such as cases and dashboards, and custom objects in a community. This license type also supports role hierarchy, sharing rules, and reports. This license type is suitable for GS regional leads who need to report damage of goods using cases and access dashboards to track regional shipping KPIs.

External Identity license for GS capacity planners. This license type allows external users to access a limited set of standard Salesforce objects, such as contacts and documents, and custom objects in a community. This license type also supports identity features, such as single sign-on (SSO) and social sign-on. This license type is suitable for GS capacity planners who need to access the third-party cloud analytics tool using Salesforce as the identity provider.

The other options are not appropriate license types for this scenario. Customer Community license for GS capacity planners would not allow them to access the third-party cloud analytics tool using SSO, as this license type does not support identity features. Identity license for GS regionalleads would not allow them to access cases and dashboards in the community, as this license type does not support standard Salesforce objects.

Delegated authentication is a feature that allows Salesforce to delegate the authentication process to an external web service. The web service needs to include the source IP address of the user as a method parameter, so that Salesforce can pass it along with the username and password. UC should whitelist all Salesforce IP ranges on their corporate firewall, so that the web service can accept requests from Salesforce. The return type of the web service methodshould be a Boolean value, indicating whether the authentication was successful or not. The web service can be written using either SOAP or REST protocol, but this is not a consideration for UC while building the web service. Delegated authentication is not enabled for the system administrator profile, but it can be enabled for other profiles or permission sets.

Dynamic branding is a feature that allows Experience Cloud sites to display differentbranding elements, such as logos, colors, or images, based on the user’s profile or preferences. To use dynamic branding, the community must be built with the Customer Account Portal template, which supports this feature. An experience ID (expid) or placeholder parameter must be used in the URL to represent the brand and trigger the dynamic branding logic.
