Test: Network Layer & Transport Layer- 2 - Question 3

Brouter

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 3

Brouter is a device, which is combination of functionality of bridge and router. So, it works till network layer and is able to bridge those protocol that are not routable.

Test: Network Layer & Transport Layer- 2 - Question 4

Who can send ICMP error-reporting messages?

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 4

Both router and destination host can send ICMP error-reporting message to inform the source host about any failure or error occurred in packet.

Test: Network Layer & Transport Layer- 2 - Question 5

Which of the following is false?

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 5

Routers can act as bridges we can use routers to bridge devices to our wireless network.

Test: Network Layer & Transport Layer- 2 - Question 6

Which of the following is incorrect regarding the Internet Control Message Protocol (ICMP)?

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 6

ICMP is error reporting protocol used when something unexpected occurs in routers, used to test connectivity while BOOTP is IP protocol network to automatically assigned an IP address to network devices from a configuration server.

Test: Network Layer & Transport Layer- 2 - Question 7

The parameter which gives the probability of the transport layer itself spontaneously terminating a connection due to internal problems is called

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 7

Resilence is a probability of transport layer to terminate a connection due to internal problems.

Test: Network Layer & Transport Layer- 2 - Question 8

To prevent silly window syndrome created by a sender that is sending data at a very slow rate _______ can be used.

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 8

Nagle's algo is used to prevent silly window syndrome created by a sender that send data at a very slow rate.

Test: Network Layer & Transport Layer- 2 - Question 9

The division of a message into segments, is a function of the

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 9

Message comes from application layer divide into segments at transport layer

Test: Network Layer & Transport Layer- 2 - Question 10

A Go-Back-N ARQ uses a window of size 15. How many bits are needed to define the sequence number?

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 10

Formula:
Window size (Go Back N) = 2n-1
Where n is bits needed
So, 15 = 2n-1
16 = 2n
So,   n = 4

Test: Network Layer & Transport Layer- 2 - Question 11

In ______ , data are sent or processed at a very inefficient rate, such as 1 byte at a time.

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 11

Silly window syndrome problem can degrade TCP performance. This problem occurs when data are passed to the sending TCP entity in large blocks, but interactive application on the receiving side reads data T byte at a time.

Test: Network Layer & Transport Layer- 2 - Question 12

An ACK number of 1000 in TCP always means that

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 12

Since sequence number of byte in any segment in TCP start from any number, so we cannot tell how many bytes successively received, on ACK number 1000.

Test: Network Layer & Transport Layer- 2 - Question 13

A TCP message consisting of 2100 bytes is passed to IP for delivery across two networks. The first network can carry a maximum payload of 1200 bytes per frame and the second network can carry a maximum payload of 400 bytes per frame, excluding network overhead. Assume that IP overhead per packet is 20 bytes. What is the total IP overhead in the second network for this transmission?

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 13

In the question they have directly given the payload so 2100 will be divided into 1200 and 904 (900 is not a multiple of 8 so we have to pad 4 bits in order to make it a multiple of 8).
Now in second network payload is 400 B.
So 1200 bytes packet will be divided in 400,400, 400 with each having 20 B header, and 900 will be divided into 400,400 and 104 (4 bits padded) each having 20 B header.
So total overhead is 20 x 6 = 120 B.

Test: Network Layer & Transport Layer- 2 - Question 14

Which of the following type of ICMP messages need to be encapsulated into an IP datagram?

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 14

Time exceeded; echo reply and multicasting ICMP messages needs to be encapsulated into if data gram to the sender side.

Test: Network Layer & Transport Layer- 2 - Question 15

Which protocol is exterior routing?

Detailed Solution for Test: Network Layer & Transport Layer- 2 - Question 15

Border Gateway protocol (BGP) is the current exterior gateway routing protocol (EGP).
