break up collisions? (Choose three.)
Bridge
Switch
Repeater Correct Ans - Which three devices forward broadcast traffic?
(Choose three.)
Router Correct Ans - Which network device allows communication
between separate IP networks?
Star Correct Ans - Hubs connect network hosts in which
configuration?
Router Correct Ans - Which network device can isolate broadcast
traffic to the local network segment?
switch Correct Ans - Which OSI/RM Data Link Layer 2 device creates
multiple network segments, each offering the full network bandwidth?
Bridge Correct Ans - Which network device allows us to connect
dissimilar network topologies?
Network Interface Card (NIC) Correct Ans - Which network device
requires a device driver in order to connect hosts to the network segment?
185m Correct Ans - Question Review
, At what maximum distance would you have to add a repeater to a 10Base2
network segment to prevent signal degradation?
Layer 3, the Network Layer. Correct Ans - Which open systems
interconnection (OSI) model layer do routers support?
By building physical address to port mappings and making forwarding
decisions based on these mappings. Correct Ans - Bridges and OSI/RM
Layer 2 switches filter traffic in which way?
Decapsulate the packet. Correct Ans - What must the Network Layer
do to a received frame first in order to determine the route over which it will
forward the datagram to the next network?
