Selected Answer: B
B. Microsegmentation: Microsegmentation is a security technique that divides a network into smaller, isolated segments to limit the movement of potential attackers within the network. It allows for fine-grained control over traffic flows, ensuring that only explicitly allowed traffic is permitted within and between segments. Microsegmentation can filter both intra-VLAN and inter-VLAN traffic, and even traffic between virtual machines (VMs) on the same host, fulfilling the organization’s requirements of restricting traffic based on security policies.
