Which of the following is a private network that is typically open to external parties, such as business partners, suppliers, and key customers?

Important Key Points:

2. They enhance collaboration by enabling external parties to access specific internal resources.
3. Extranets are widely used in supply chain management, customer relationship management, and vendor communication.
