An organization would like to store customer data on a separate part of the network that is not accessible to users on the main corporate network. Which of the following should the administrator use to accomplish this goal?

Segmentation is the process of dividing a network into smaller, isolated sub-networks. This allows the organization to separate the customer data from the main corporate network, restricting access only to authorized personnel or systems. This enhances security by limiting the scope of a breach if one occurs on the corporate network. Isolation, while related, is a broader term that can refer to various security measures, not specifically network division. Patching is the process of applying updates to fix vulnerabilities, which is important for security but doesn't address network separation. Encryption protects data confidentiality but doesn't inherently separate network access.
