Final answer:
The correct mode to capture all headers in wireless traffic is Option 2 monitor mode, which enables the capture of all wireless traffic irrespective of the destination.
Step-by-step explanation:
The correct answer is option Monitor. To capture all headers in wireless traffic, a network interface must be put into monitor mode. Unlike promiscuous mode, which is used for wired networks to capture packets not destined to the host's network interface, monitor mode allows the capture of all wireless traffic visible to the network device, even if it is not addressed to any particular host. This means that the network adapter will not only capture packets intended for it but will listen to all packets transmitted on the wireless frequency it is tuned to. This is particularly useful for network analysis and security testing as it allows for the observation of all wireless traffic and can help in diagnosing network issues or detecting unauthorized access.
When a network interface is configured in promiscuous mode, it allows the capturing of all headers in wireless traffic.
This mode allows the network interface to read and capture all the data packets on the network, including those that are not intended for the device. It is commonly used for network analysis, monitoring, and troubleshooting purposes.
