A technician must install and configure a network device in a building with 20 classrooms.
Each room must be on a separate subnet and should not be able to see traffic from other subnets.
Which of the following is the MOST cost-effective solution?
A.
A switch with VLANs created for each segment B.
A router with interfaces connected to a switch in each room C.
A VoIP endpoint connected to a hub for each network D.
A firewall with DHCP pools for each subnet.

The most cost-effective solution for the given scenario is option A: A switch with VLANs created for each segment.
Explanation: VLANs (Virtual Local Area Networks) are used to segment a network into multiple broadcast domains. By creating a separate VLAN for each classroom, we can ensure that devices on one VLAN cannot see traffic from devices on other VLANs.
A switch with VLAN support is a cost-effective solution because it can be used to create multiple VLANs without requiring additional physical hardware. VLANs can be created and configured on a single switch, and each port can be assigned to a particular VLAN.
Option B, which involves using a router with interfaces connected to a switch in each room, is not a cost-effective solution. It requires multiple routers and switches, which can increase the cost significantly.
Option C, which involves using a VoIP endpoint connected to a hub for each network, is not a feasible solution for creating separate subnets. Hubs are not capable of segmenting traffic and creating separate broadcast domains.
Option D, which involves using a firewall with DHCP pools for each subnet, is also not a cost-effective solution. While a firewall can be used to block traffic between subnets, it is typically more expensive than a switch with VLAN support. Additionally, using DHCP pools for each subnet would require a separate DHCP server or a firewall with DHCP capabilities, which can also increase the cost.
Therefore, the most cost-effective solution for creating separate subnets in each classroom is to use a switch with VLANs created for each segment.
