VMware Certified Professional - Data Center Virtualization (VCP-DCV) Practice Exam

Enabling Promiscuous Mode on a port group allows a virtual machine to receive all traffic on that network segment, not just the traffic intended for it. This is particularly useful when capturing network traffic, as it ensures that the virtual machine can see all packets traversing the virtual switch, thereby giving a complete view of the network traffic.

When Promiscuous Mode is enabled, the virtual switch will pass all packets to the VM, including broadcast and multicast packets, which are essential for effective network analysis. This functionality is crucial for monitoring and troubleshooting network issues, conducting security assessments, or performing network traffic captures with tools like Wireshark.

Setting the proper MTU size, using an external network switch, or installing the latest VM tools may offer benefits in different contexts but do not directly influence the ability of a virtual machine to capture and analyze all network traffic.
