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?

Is the transition area between digital and analog signals and can be found between layer 2 and layer 3 of the protocol stack.

Identifies application direct messaging and is formed between layers 3 and 4.

Identifies the point between IP addressing and MAC addressing, between the Link (network interface) and Internet layers.

Identifies the transition area between UDP and TCP protocols, and can be found between the Application and Transport Layers.

Question 4

In the IP address hierarchy, each 32-bit IP address is divided into two parts:

Prefix; Suffix

a time to live (TTL); a time to die (TTD)

Part A; Part B

a unique network number; a locally assigned suffix

both a and d

both b and c.

Question 5

Each hardware technology specifies the maximum amount of data that a frame can carry. This limit is known as ___________________________________________________.

The header checksum

a flag

padding

the maximum transmission unit

Question 7 Time-To-Live is a key component of the IP datagram header format. Time to Live is an eight bit integer initialized by the original sender and decremented by each router that processes the datagram. What happens when the value of the datagram integer reaches a value of zero?

The datagram forms a loop and is resent by the original sender

The datagram is discarded

The datagram is sent to the next router, then returned to sender

An error message is sent back to the source

a and c above

b and d above

Question 8

Best effort delivery is __________________________.

A misnomer, as TCP guarantees delivery to all packets transported using the TCP/IP protocol suite.

A concept to deliver messages across the network but does not provide special handling for corrupted or lost packets.

Identifies a quick delivery system using complex routing tables, which must be preprogrammed before message/packet transmission.

A misnomer, as UDP guarantees delivery to all packets transported using the TCP/IP protocol suite.
