Explanation:

The requirement is to show a different Hero component on the same page (the Home page) based on the user's region. The most efficient and targeted way to do this in Experience Builder is by using Audience Targeting at the component level.

Why D is Correct: This is the standard and correct procedure:
You have one Home page.
You add multiple Hero components to that single page.
You configure Audience Targeting for each Hero component—one targeted to an "EMEA" audience and the other targeted to a "United States" audience.
When a user from EMEA visits the page, they see only the EMEA Hero component. A user from the US sees only the US Hero component. This keeps the page management simple and applies the personalization directly to the specific content.

Why the Other Options are Incorrect:

Why A is Incorrect:
Configuring the Theme (or a Branding Set) changes global styles like colors and logos, not the specific content of a single component on a single page. A page variation is also a heavier solution than necessary when only one component needs to change.

Why B is Incorrect:
A page variation creates an entirely separate copy of a page for a specific audience. This is useful when many elements on a page need to change, but it is overkill and inefficient for changing just one component. It also creates more maintenance overhead, as any future change to the Home page must be made in two places (the original and the variation).

Why C is Incorrect:
Using multiple targeted HTML components is a clunky workaround. The Hero is a specific, powerful component with its own configuration and design tools. Forcing it into an HTML component is not the standard method and loses the functionality of the native component. The correct approach is to target the Hero components themselves.

Explanation

Here is a breakdown of why this option is the most suitable:

Distinct user needs:
B2C customers need a simple, self-service-oriented site, while B2B customers require a more advanced portal for managing partner-related tasks. Using separate experiences prevents B2C users from being overwhelmed and gives B2B users the tools they need.
Data security:
Keeping the experiences separate is crucial for protecting data. B2C customers should not be able to see B2B account or partner information, and vice-versa.
Targeted functionality:
A B2C-focused site can be optimized for self-service with knowledge articles and case submission. A partner portal for B2B users can be customized for their specific needs, like accessing shared cases and collaborating with UC's support team.
Internal vs. External Access:
Employees should continue to use the internal CRM for full access to records and administration. Experience Cloud sites provide a secure, separate point of entry for external users.

Why the other options are incorrect

B. Create a single digital experience for B2C customers, B2B customers, and employees.
This is a significant security risk. It makes data sharing and user management extremely complex and exposes internal and B2B partner data to B2C users.
C. Create a digital experience for B2B customers, a partner portal for B2B customers, and use the internal CRM org for employees.
This option is redundant and confusing. A "digital experience for B2B customers" and a "partner portal for B2B customers" essentially describe the same thing in this context. B2B customers would be configured as partner users who access a partner portal.
D. Create a digital experience for B2C customer and employees, and another one for B2B customers and employees.
It is not best practice to mix internal employees with external customers in the same digital experience. Employees should work in the internal CRM, which offers a full suite of tools and permissions, and only access external portals when necessary for support. The security and customization needs of internal users are also vastly different from external users.

Explanation:

The core of the problem is that the manager has too much access. They should only be able to manage external partner users but are also able to modify internal user records. This points to a permission that is too broad.

Why C is Correct:
The "Manage Users" permission is a very powerful system permission. When granted, it allows a user to deactivate, freeze, and reset passwords for all users in the org, including both internal and external users. This explains why the manager has the unintended ability to make organizational changes to internal users.

Why the Other Options are Incorrect:

Why A is Incorrect:
The "Manage Profiles and Permission Sets" permission allows a user to create and modify profiles and permission sets. It does not, by itself, grant the ability to edit or deactivate user records.

Why B is Incorrect:
"Manage Customer Users" is not a standard, discrete permission in Salesforce. The correct, granular permission for this function is "Manage External Users."

Why D is Incorrect:
The "Manage External Users" permission is the correct and recommended permission for this scenario. It allows a user to create and manage external users only (e.g., Community users). If the manager only had this permission, they would not be able to modify internal users, which is the desired outcome. The fact that they can modify internal users proves they have a permission that is broader than just "Manage External Users."

Reference:
Salesforce Help: Delegate Administration for External Users - This article specifies that to manage external users, the delegated admin needs the "Manage External Users" permission. The broader "Manage Users" permission is not required and is excessive.
Salesforce Help: Manage Users Permission - This states that the "Manage Users" permission allows a user to "deactivate, freeze, or reset passwords for all users," explaining the overreach described in the problem.

Explanation:

For external users, such as partner users in a Partner Digital Experience (formerly Partner Community), to participate in a Salesforce Approval Process, they must have the following two components:
A Digital Experience (Partner Community): This provides them with a secure external interface and access to the necessary records (installation projects/deals). This is explicitly mentioned in all the correct options (A and C).
Assignment as an Approver: External users can be designated approvers in an Approval Process in one of two standard ways:
Assign External Users as Approvers (Option A):
This is the direct and most common way. An Approval Step can be configured to assign the approval request to a specific User (the external partner user). This typically relies on a User lookup field on the record (e.g., a custom Partner Approver lookup field on the Project/Deal object) or by explicitly selecting the user in the approval step.
Add External Users to Approval Queues (Option C):
Approval steps can be assigned to a Queue. External users (partner users) can be members of a Queue, and any member of that Queue can then approve or reject the request. This is a common way to distribute approval workload among a group of partners.

❌ Incorrect Answers
B. Assign external users as the co-owners on records and create a digital experience for those users.
Reason: Record ownership or co-ownership primarily controls data visibility and edit access, not the approval flow itself. While it may grant them access to the record, it does not automatically make them an approver in a standard Salesforce Approval Process. The approval must be explicitly assigned via a User field or a Queue.

D. Assign external users Super User access on records and create a digital experience for those users.
Reason: Super User Access is a specific feature in Salesforce Experience Cloud (specifically for Partner/Customer Community users) that grants a user elevated privileges to view and manage data for their entire account or partner group. While they must have a Digital Experience, "Super User" status does not, by itself, grant them an approval assignment in a standard Approval Process. The approval assignment still needs to be made through the Approval Step configuration (User or Queue).

Explanation:

Get Cloud Consultant (GCC) is designing a complex, global Salesforce solution for a coffee brand that connects researchers and coffee growers across the world. Researchers are external experts who submit detailed cultivation recommendations, which must pass through a multi-step approval process before reaching growers who implement them in the field. Beyond the core workflow, the company plans to use Salesforce to manage incentives, compensations, distribution logistics, and long-term yield projections, requiring at least 20 custom objects—far beyond basic case or content management. These objects will store research data, approval history, grower assignments, compensation tiers, shipment tracking, and predictive models. The researchers are not customers placing orders, nor partners selling coffee; they are external collaborators needing deep system access without touching standard CRM objects like Leads, Opportunities, or Campaigns. The External Apps license (previously known as Lightning External Apps Plus) is the only one that meets all requirements. It supports over 100 custom objects, includes 10 MB of file storage per user, provides API access for potential integrations, and comes as a single org-wide SKU, making it scalable for a global researcher network. Users get full create/edit rights on custom objects, can participate in approval processes, upload supporting documents, and view dashboards—all while remaining completely isolated from internal sales or service data. This license ensures security, flexibility, and future-proofing as the solution grows.

Why Option A Is Incorrect
Customer Community is built for simple self-service portals. It allows only 10 custom objects per user, which is immediately insufficient for 20+ objects. It focuses on Knowledge articles, case deflection, and basic forms—not complex approval chains or research data management. Researchers would hit object limits and lack workflow depth.

Why Option C Is Incorrect
Partner Community Plus is tailored for channel sales partners. It includes access to Leads, Opportunities, Deal Registration, and revenue-sharing tools. Researchers do not sell or manage pipeline. Giving them this license would expose sensitive sales data and provide irrelevant features, violating least privilege and increasing risk.

Why Option D Is Incorrect
Customer Community Plus supports up to 100 custom objects and adds reports, dashboards, and enhanced sharing. While technically capable of handling 20 objects, it is customer-oriented and assumes users are buyers or support seekers. It lacks the external collaboration focus and high API/storage limits of External Apps. It is also more expensive per user and less aligned with a researcher workflow.
