Test: Introduction & IP Addressing- 2 - Question 1

To prevent signal alternation, what is the max number of repeaters that can be placed on one 10 Base 5 or 10.Base 2 network?

Detailed Solution: Question 1

Maximum 4 repeaters can be placed in one transmission path between two nodes while 5 between two nodes.

Test: Introduction & IP Addressing- 2 - Question 2

Which IP class provides the fewest numbers of hosts?

Detailed Solution: Question 2

Option C is correct.

Class A: 224 - 2 = 16,777,214 usable hosts per network.

Class B: 216 - 2 = 65,534 usable hosts per network.

Class C: 28 - 2 = 254 usable hosts per network.

Class D: 0 usable hosts; it is reserved for multicast and does not provide host addresses.

Therefore, Class D provides the fewest number of hosts (zero), so the correct option is Option C.

Test: Introduction & IP Addressing- 2 - Question 3

A repeater takes a weak and or corrupted signal and _____ it.

Detailed Solution: Question 3

A repeater takes a weak or corrupted signal and regenerate it

Test: Introduction & IP Addressing- 2 - Question 4

A subnet mask in class A can have ______ 1’s with the remaining bits 0’s.

Detailed Solution: Question 4

Default subnet mask of class A network 11111111-00000000-00000000-00000000 
⇒ 255-0-0-0.

Test: Introduction & IP Addressing- 2 - Question 5

To interconnect two IP classes, class A and class C networks

Detailed Solution: Question 5

Router is used to connect two different class networks.

Test: Introduction & IP Addressing- 2 - Question 6

Given an IP address 156.233.42.56 with a subnet mask of 7 bits. How many hosts and subnets are possible.

Detailed Solution: Question 6

Test: Introduction & IP Addressing- 2 - Question 7

Class_______has the greatest number of hosts per given network address.

Detailed Solution: Question 7

Number of hosts in class A = 224 - 2 Number of hosts in class B = 216 - 2 Number of hosts in class C = 28 - 2

Test: Introduction & IP Addressing- 2 - Question 8

The effective bandwidth is based on ______ .

Detailed Solution: Question 8

The effective data burst is a measure of average data rate, peak data rate and maximum data rate.

Test: Introduction & IP Addressing- 2 - Question 9

Identify the unequal pair(s):

Detailed Solution: Question 9

Physical address is also known as MAC address. Logical address is also known as IP address COM1 is a communication port.

Test: Introduction & IP Addressing- 2 - Question 10

There are three IP addresses as given below:
X = 202.23.14.150 
Y = 168.19.200.12 
Z = 72.192.52.210

Which of the following statements is/are correct?

Detailed Solution: Question 10

In IP add re sse s class A, B, and C used for general purpose.

Test: Introduction & IP Addressing- 2 - Question 11

The default subnet mask for a Class B network can be

Detailed Solution: Question 11

If IP address is AND with subnet mask result will network address.
Default subnet mask:
Class A = 255.0.0.0
Class B = 255.255.0.0
Class C = 255.255.255.0

Test: Introduction & IP Addressing- 2 - Question 12

Match List-I (Function) with List-11 (Layer) and select the correct answer using the codes given below the lists:

Detailed Solution: Question 12

Packet switching→ network iayer.
Route determination→ 4 network layer.
Flow control → datalink and transport layer.

Test: Introduction & IP Addressing- 2 - Question 13

Match List-I (Function) with List-lI (Layer) and select the correct answer using the codes given below the lists

List-I
A. Reassembly of packets
B. Responsibility for delivery between adjacent nodes
C. Mechanical electrical and functional interface
D. Error correction and retransmission

List-II
1. Transport
2. Data link
3. Physical 

Detailed Solution: Question 13

  • Reassembly of packets is done at transport iayer.
  • Responsibility for delivery between adjacent nodes is of data link layer.
  • Mechanical electrical and functional interface is related to physical layer. 
  •  Error correction and retransmission is done at data link layer as well as transport layer. 

Test: Introduction & IP Addressing- 2 - Question 14

A subnet mask in class A has fourteen 1’s. How many subnet does it define?

Detailed Solution: Question 14

Subnet mask

6 bit are used for subnetting.
So number of possible subnets - 26 = 64.

Test: Introduction & IP Addressing- 2 - Question 15

In a class A subnet, we know the IP address of one of the hosts and the mask as given below:
IP address = 25.34.12.56
Mask = 255.255.0.0

What is the first address (network address)?
