QUESTION 1

Select the correct statement regarding autonomous systems (aka autonomous networks).

a. autonomous systems describes a network that is fully automated (i.e., no human interaction)

b. autonomous systems only describes machine-to-machine (M2M) communications

c. an autonomous system describes an OSI layer 3 network (Internet) where a single service provider controls its network configuration (e.g., Internet Service Provider, ISP)

d. None of the above are correct

QUESTION 2

Select the correct statement regarding the Internet Protocol (IP).

a. IP is a connection-oriented protocol

b. IP does not guarantee the delivery of correct packet sequencing

c. IP guarantees packet delivery

d. None of the above are correct

QUESTION 3

Since IP is a connectionless protocol, each datagram must contain both source and destination network addresses.

True

False

What is the purpose of the "time-to-live" (TTL) field of the IPv4 packet?

a. ensures that the packet remains in the network long enough to reach its destination

b. it was used when the Internet was very slow, but is no longer needed

c. it prevents the packet from remaining indefinitely in the network thus helping to prevent network congestion

d. none of the above describes the purpose of the TTL field
