A network engineer is redesigning a campus network. The current network uses a single /16 subnet for 1000 devices. The engineer wants to reduce broadcast traffic but also needs to keep the number of subnets manageable. The engineer decides to use /24 subnets. What is the trade-off of this approach?

The network becomes more secure because each subnet has its own firewall.

Broadcast traffic is eliminated, and no routing is needed because all subnets are directly connected.

The total number of usable addresses increases because more subnets are created.

Broadcast traffic is reduced, but more IP addresses are consumed by subnet and broadcast addresses, and routing between subnets is required.

A company has a single /24 network with 200 devices. The network is experiencing performance issues due to broadcast traffic. The administrator wants to reduce the broadcast domain size while keeping the ability for all devices to communicate with each other. The administrator also wants to minimize the number of new subnets to reduce routing complexity. Which approach best meets these requirements?

Create two /26 subnets and route between them.

Create two /25 subnets and route between them.

Create four /26 subnets and route between them.

Keep the /24 subnet but replace the switch with a router.
