Which product allows customers to log into the corporate website, view solutions from a knowledge base, and log cases?

The correct choice is the self-service portal, which provides a platform for customers to access and log into a corporate website where they can view solutions from a knowledge base and log cases. This type of portal is designed to empower customers by giving them the tools to find answers to their questions independently and easily submit support requests if further assistance is needed.

A self-service portal enhances customer experience by enabling users to seek solutions at their convenience, browse FAQs, and utilize various resources in the knowledge base without the need for direct interaction with support staff. Features often include user-friendly navigation and search functionalities to help customers quickly find the information they need.

In contrast, Web-to-Case primarily focuses on creating cases directly from web forms but does not inherently provide a comprehensive user interface for knowledge base access or case management like a self-service portal does. Force.com Sites allows developers to create public sites and applications but isn’t tailored specifically for customer service interactions like a self-service portal. The customer portal also provides similar functionality but is designed for specific user types and often requires additional configuration based on user permissions and case management features.

Overall, the self-service portal distinctly combines knowledge access and case logging in a user-centric design, making it the most appropriate choice for the described functionalities.
