A network administrator needs to segment a single physical switch into multiple, isolated broadcast domains to improve security and reduce unnecessary traffic. Which of the following technologies should the administrator implement to achieve this?
A VLAN (Virtual Local Area Network) is the correct technology for this scenario. VLANs logically partition a physical switch into multiple, separate broadcast domains, which isolates traffic and enhances security on the same physical hardware. A VPN (Virtual Private Network) is used to create a secure connection over an untrusted network. A VPC (Virtual Private Cloud) is a private network segment within a public cloud provider's infrastructure. An SDN (Software-Defined Network) is a network architecture approach and not the specific technology used for segmenting a switch in this manner.
