ESXi provides VLAN support by assigning a VLAN ID to which component?

• A. Physical network interface card (NIC)
• B. Virtual distributed switch
• C. Port group
• D. Virtual standard switch

Answer: (C)

VLAN support in ESXi is implemented through the use of port groups. A port group serves as a logical entity that defines a set of rules and policies for virtual machine network traffic. When a VLAN ID is assigned to a port group, it allows the virtual machines that are connected to that port group to communicate over a specific VLAN. This configuration ensures that traffic is appropriately tagged with the VLAN ID, enabling proper segmentation and isolation across the network. Port groups are essential in organizing and managing network traffic efficiently, especially in environments that utilize VLANs for traffic isolation and improved security. With VLAN IDs assigned to port groups, network administrators can easily control which virtual machines can communicate with each other based on the VLANs they are part of. This method enhances the application's performance and security within a virtualized environment.
