QUESTION 1
IPv4 addresses are managed and controlled by Internet Service Providers (ISPs) which operate on a local basis. As such, Internet Exchange Points (IXPs) must map incoming and outgoing IP addresses between ISPs.
True
False
3.33 points
QUESTION 2
Select the correct statement(s) regarding the Internet architecture.
|
a. IXPs and NAPs are responsible for the mapping of intranet and Internet IP adresses |
||
|
b. Interior Gateway Protocols (IGPs) are use to share packet routing information between autonomous systems (AS') |
||
|
c. peering agreements between service providers enables the free flow of IP packets at an IXP |
||
|
d. all statements are correct |
3.33 points
QUESTION 3
Which protocol is used to enable the exchange of layer 3 routing information between autonomous systems (AS’)?
|
a. NAP |
||
|
b. IGP |
||
|
c. BGP |
||
|
d. TCP |
3.33 points
QUESTION 4
What is true about the Internet Protocol (IPv4)?
|
a. although IP datagrams can take different paths through the network, IP guarantees proper packet sequencing |
||
|
b. IPv4 implements flow control by use of acknowledgements and "widowing" |
||
|
c. IPv4 addresses identify the network ID and host ID |
||
|
d. IPv4 frames/datagrams have fixed lengths, which enable real time data streaming |
1) True
Explanation: Yes, IP's are managed by ISP and they provide
us the internet
2) A and C
3) BGP
Explanation: Exterior gateway protocol used to
exchange of layer 3 routing information between AS
4) IPv4 addresses identify the network ID and host ID
Explanation: IPv4 addresses identify NID and
HID

Question 1 The size of the datagram is determined by the application that sends the data. Allowing the size of datagrams to vary makes IP adaptable to a variety of applications. True False Question 2 What is the conceptual network boundary, and where is it located within the protocol stack?

QUESTION 1 "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second that can be transmitted by the link (use a whole number)?"...
