T/F A Spanning Tree Algorithm helps prevent broadcast Storms - Answers True
What are the service that TCP provides - Answers Flow Control
Congestion Control
In order Deliver of Packets
T/F If you build an application on top of UDP you can't incorporate additional services at the
application layer itself, that are not offered by UDP - Answers False
Hosts, routers, switches and middlebox devices are expected to implements all layers of the
internet protocol stack - Answers False
As a packet traverses the path from source to destination along the physical layer, each node de
-encapsulates the packet before sending it - Answers False
The end to end principle suggests the network core minimal and offload the intelligence to the
end systems - Answers True
Most innovation has happened at the protocol layers at the 'waist' of the hourglass - Answers
False
The Evolutionary Architecture model suggests that the ip protocol survived because the
protocols at the transport layer have been stable themselves - Answers True
The Evolutionary Architecture model suggests TCP/IP stack did not compete with pre-existing
network services, instead it targeted new applications - Answers True
The Evolutionary Architecture model predicts new internet architectures will have an hourglass
shape - Answers True
Hubs can be used interchangeably with layer 2 switches - Answers False
Which are true about learning bridges:
-a network operator needs to configure the forwarding table
-a learning bridge populates the forwarding table based on the network traffic conditions such
as volume and traffic disruptions
-The forwarding table represents which hosts are reachable through which ports - Answers The
forwarding table represents which hosts are reachable through which ports
The goal of the spanning tree algorithm is to have bridges select which ports to use for
forwarding in order to eliminate loops - Answers True
