A new server was installed for the purpose of monitoring network traffic. The network has been
configured in such a way that all traffic will be mirrored out the port this server is connected to. When
reviewing the network traffic logs on the server only traffic destined to the server is listed in the logs.
Which of the following is preventing the server from seeing all network traffic?
A.
NIC filtering is enabled.
B.
Port security is configured.
C.
NIC is not in promiscuous mode.
D.
NIC is in promiscuous mode.
In computer networking, promiscuous mode or promisc mode is a mode for a wired network interface controller (NIC) or wireless network interface controller (WNIC) that causes the controller to pass all traffic it receives to the central processing unit (CPU) rather than passing only the frames that the controller is intended to receive.
