What is the primary purpose of configuring access control on a switch?

Configuring access control on a switch is fundamentally about preventing unauthorized network access. Access control mechanisms, such as VLANs, port security, and access control lists (ACLs), are implemented to ensure that only authorized devices can communicate on the network. This is vital for maintaining the security and integrity of the network as well as protecting sensitive information from being intercepted or accessed by malicious actors.

While enhancing network performance or increasing the speed of data transmission may be indirect benefits of a secure network configuration, the primary goal remains the protection of the network resources. Similarly, minimizing hardware costs is not directly related to access control; costs can vary based on numerous factors, including specifications and needs of the network, but do not inherently connect to the purpose of access control functionality.
