In network segmentation, what strategy should a network engineer use to segment different types of hosts attached to the same switch?

Using virtual local area networks (VLANs) to segment different types of hosts attached to the same switch is an effective strategy for enhancing network security and efficiency. VLANs allow network engineers to group devices based on factors such as function, application, or user type, even if they are connected to the same physical switch. This logical separation restricts broadcast traffic and limits the scope of potential security breaches, as devices in one VLAN cannot directly communicate with devices in another VLAN without a router or Layer 3 switch that has inter-VLAN routing capabilities.

By assigning hosts to different VLANs, engineers can apply tailored security policies, manage traffic patterns more effectively, and implement targeted access controls. This segmentation makes it more challenging for malicious actors to move laterally within the network and can help in containing potential security incidents.

Assigning static IP addresses, using physical separation with additional switches, or implementing a firewall for each host may address specific concerns but would not provide the same level of flexibility and efficiency as VLANs. Static IP addressing does not inherently provide segmentation, while physical separation increases costs and introduces complexity. Firewalls for each host can be resource-intensive and may not be practical in all scenarios. Thus, utilizing VLANs is the most efficient and effective choice for segment
