"Routing" and "forwarding" are interchangeable terms - CORRECT ANSWER: False
*** Look at the unibit trie questions - CORRECT ANSWER:
*** Review the diagrams quiz questions for quiz 4 - CORRECT ANSWER:
A Content Distribution Network (CDN) or ISP can operate over multiple Autonomous
Systems - CORRECT ANSWER: True
A sending host receives a message from the application layer and encapsulates it with
the transport layer header before passing it down to the network layer - CORRECT
ANSWER: True
According to the end-to-end principle, where should most of the Internet's
functionality/intelligence be implemented? - CORRECT ANSWER: At the edges of a
network
According to the hot potato routing technique, it is in a network's best interest to route
the traffic so that it exits the network at the router geographically closest to the one from
which it entered the network - CORRECT ANSWER: False
An application running on a host can bind to multiple sockets simultaneously -
CORRECT ANSWER: True
, An AS can use LocalPref to control which routers are used as exit points (for the
outgoing traffic), and it can use the MED attribute to control which routers are used as
entry points (for the incoming traffic) - CORRECT ANSWER: True
AN IXP route server does not need to run the BGP protocol to facilitate the
establishment of multi-lateral peering sessions - CORRECT ANSWER: False
As Autonomous System operates across multiple administrative domains - CORRECT
ANSWER: False
Assume a source and destination host. As packets travel over a path from the source
host to the destination host the packets are handled by multiple routers over that path. If
these routers belong to different administrative domains, they need to run the same
intradomain routing algorithm, since they are on the same path for that pair of hosts -
CORRECT ANSWER: False
Assume Hosts A, B, and C. Host A has a UDP socket with port 123. Hosts B and C each
send their own UDP segment to Host A. Hosts B and C cannot use the same
destination port 123 for sending their UDP segment - CORRECT ANSWER: False
At an IXP, the members have a choice to peer privately or publicly - CORRECT
ANSWER: True
Both the data link and transports layer protocols may provide error correction -
CORRECT ANSWER: True
By stride we refer to the number of bits that we check at every step when traversing a
trie. - CORRECT ANSWER: True
Congestion control is a rate control mechanism to protect the network from congestion -
CORRECT ANSWER: True
