Which of the following is a capability of VLAN in practical application?

In practical applications, the capability of VLANs (Virtual Local Area Networks) allows for partitioning of network segments, enhancing security and managing broadcast traffic. The correct choice emphasizes that virtual machines (VMs) within the same VLAN can operate with IP addresses that belong to different address segments, while still maintaining the ability to communicate effectively, particularly through broadcast mechanisms.

This highlights the flexibility and versatility of VLANs. Broadcasts within a VLAN allow VMs to discover each other, facilitating communication without requiring all devices to be on the same IP address segment. This capability is crucial for organizational flexibility, allowing a mix of subnets and addressing schemes without compromising connectivity among VM instances within the same logical group.

In contrast, other options suggest limitations or misunderstand VLAN operations. For instance, the notion that VMs must share an IP address segment to communicate contradicts the fundamental workings of VLANs. Similarly, while it's true that VMs on different VLANs cannot directly communicate, their operational independence in terms of IP addressing is not accurately portrayed in the other options. The emphasis on broadcasts allows for streamlined communication processes in varied network configurations, making choice C the most accurate representation of VLAN capabilities.
