Answer: BC

Explanation:

+ Position in the network flow: Directly inline with the flow of network traffic and every packet goes through the sensor on its way through the network.

+ Mode: Inline mode

+ The IPS can drop the packet on its own because it is inline. The IPS can also request assistance from

another device to block future packets just as the IDS does.
