An administrator tries to capture network traffic for a virtual machine, but cannot see the expected traffic in the packet capture tool. Which step can resolve the problem?

Migrating to a Distributed Virtual Switch changes the switch type but does not by itself enable promiscuous access; the security policy must still be changed to allow the capture VM to see all traffic.

By default, a virtual switch drops frames not destined for the vNIC's MAC address; enabling Promiscuous Mode on the port group overrides this behavior and allows the network adapter to pass all traffic to the guest OS, which is required for a packet capture tool to observe traffic from other virtual machines on the same segment.

MAC Address Changes controls whether the guest can alter its own MAC address; it does not affect whether the vNIC receives frames destined for other MAC addresses.

Forged Transmits controls whether frames sent with a MAC different from the vNIC's configured address are allowed to leave the port; it does not enable reception of traffic addressed to other machines.
