A. users could access network servers faster B. different vendor networks could work with each other C. the industry could create a standard for how computers work D. network administrators could increase the overall speed of their network

1 3768

Which statement is true? A. While bridges are used to segment networks, they will not isolate broadcast or multicast packets. B. A bridge looks at every packet within its network segment and works like a hub re-broadcasting the packet if the destination is within its network segment. C. A bridge maintains a table of the IP addresses of the hosts within its network segment and forwards the packet directly to the destination based upon the IP address. D. A bridge resets the hop count by keeping all packets within the network segment. Only packets addressed to a specific destination host outside the network segment are allowed to pass through the bridge.
