An administrator needs to create two websites for different user groups. What types of websites should be created for internal users and external customers?

The correct answer is to create an intranet for internal users and an extranet for external customers. An intranet is a private network accessible only to an organization's staff, designed for internal use. This environment can house resources, tools, and information meant solely for employees, facilitating better communication and collaboration.

On the other hand, an extranet extends certain areas of access to external users, often clients or partners. It allows them to interact with the organization and access specific data or services while maintaining the security and integrity of internal operations. This hosted platform fosters collaboration with external parties and ensures that sensitive information remains protected.

Thus, this arrangement meets the needs of having a centralized resource for internal staff while simultaneously providing external customers access to necessary tools or information pertinent to their relationship with the organization. This differentiation between intranet and extranet is vital in ensuring appropriate access controls and maintaining a secure operational environment.
