Final answer:
A logical grouping of computers that allows them to act as if they were attached to the same broadcast domain is called a Virtual Local Area Network (VLAN).
Therefore, the correct answer is: option d)- Virtual Local Area Network (VLAN)
Step-by-step explanation:
A VLAN is a network within a network that can be created using switches and VLAN tags. It allows for segmentation and isolation of network traffic, improving network performance and security.
It also refers to a logical grouping of computers that allow computer hosts to act as if they were attached to the same broadcast domain, regardless of their physical location, is Virtual Local Area Network (VLAN).
VLANs allow network administrators to automatically limit access to a specified group of users by dividing workstations into different isolated LAN segments. When users move their workstations, administrators don't need to reconfigure the network or change VLAN groups.
VLANs provide a number of advantages including ease of administration, confinement of broadcast domains, reduced network traffic, and enforcement of security policies.
