CS 6250 EXAM QUESTIONS WITH CORRECT SOLUTIONS|100% PASS|GRADE A+
GUARANTEED
T/F A Spanning Tree Algorithm helps prevent broadcast Storms - CORRECT ANSWER -
True
What are the service that TCP provides - CORRECT ANSWER -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 - CORRECT ANSWER -False
Hosts, routers, switches and middlebox devices are expected to implements all layers of the
internet protocol stack - CORRECT ANSWER -False
As a packet traverses the path from source to destination along the physical layer, each node
de-encapsulates the packet before sending it - CORRECT ANSWER -False
The end to end principle suggests the network core minimal and offload the intelligence to
the end systems - CORRECT ANSWER -True
Most innovation has happened at the protocol layers at the 'waist' of the hourglass -
CORRECT ANSWER -False
, The Evolutionary Architecture model suggests that the ip protocol survived because the
protocols at the transport layer have been stable themselves - CORRECT ANSWER -True
The Evolutionary Architecture model suggests TCP/IP stack did not compete with pre-
existing network services, instead it targeted new applications - CORRECT ANSWER -True
The Evolutionary Architecture model predicts new internet architectures will have an
hourglass shape - CORRECT ANSWER -True
Hubs can be used interchangeably with layer 2 switches - CORRECT ANSWER -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 -
CORRECT ANSWER -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 - CORRECT ANSWER -True
UDP and TCP have a large overlap of functionalilites - CORRECT ANSWER -False
The transport layer offers a logical connection between hosts given that the hosts reside in
the same network - CORRECT ANSWER -False
A sender receives a message from the application layer it encapsulates it with the transport
layer header before passing it down to the network layer - CORRECT ANSWER -True
