Which of the following BEST reduces the ability of one device to capture the packets that are meant
for another device?

A.
Filters

B.
Switches

C.
Routers

D.
Firewalls

Explanation:
Switches are at the lowest level of network security and transmit a packet to the device to which it
is addressed. This reduces the ability of one device to capture the packets that are meant for
another device. Filters allow for some basic isolationof network traffic based on the destination
addresses. Routers allow packets to be given or denied access based on the addresses of the
sender and receiver and the type of packet. Firewalls are a collection of computer and network
equipment used toallow communications to flow out of the organization and restrict
communications flowing into the organization.
