What is the purpose of an IP Address?
Correct Answer
C. A network location identifier
Explanation
The purpose of an IP address is to serve as a network location identifier. It is a unique identifier assigned to each device connected to a network, allowing it to be located and communicated with on that network. An IP address helps in routing data packets between different devices and networks, enabling effective communication and data transfer.
2.
The full form of IP in IP Address is ______.
Correct Answer
B. Internet Protocol address
Explanation
The full form of IP in IP Address is Internet Protocol address. An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: identifying the host or network interface and providing the location of the device in the network. Therefore, the correct answer is Internet Protocol address.
3.
There are ______ bits in an octet?
Correct Answer
A. 8
Explanation
An octet is a unit of digital information that consists of 8 bits. Each bit represents a binary value of either 0 or 1. Therefore, the correct answer is 8, as there are 8 bits in an octet.
4.
What is the name of the type of notation an IP address is usually written?
Correct Answer
B. Dotted quad
Explanation
An IP address is usually written in a type of notation called "dotted quad". This notation represents the IP address as four sets of numbers separated by periods, where each set represents one byte of the address. Each byte can have a value between 0 and 255, resulting in a total of four sets of numbers ranging from 0 to 255. This notation is commonly used to represent IPv4 addresses.
5.
Unicast is considered one to one type of communication. True or false?
Correct Answer
A. True
Explanation
Unicast communication refers to a one-to-one type of communication where data is sent from a single sender to a specific recipient. In this type of communication, the sender addresses the data to a specific IP address, and it is received by only one device at the destination. Therefore, the statement "Unicast is considered one to one type of communication" is true.

Given the IP address 152.16.168.196/28, is the IP address 162.16.168.30 in the same network.
Correct Answer
B. NO
Explanation
The IP address 162.16.168.30 is not in the same network as 152.16.168.196/28 because the subnet mask /28 indicates that the network can only have 16 IP addresses. The IP address 162.16.168.30 falls outside of this range and therefore is not in the same network.
7.
What does /28 represent in the previous question?
Correct Answer
B. The number of bits in the network portion of the IP address
Explanation
The /28 represents the number of bits in the network portion of the IP address. In IP addressing, the network portion identifies the network to which the IP address belongs, while the host portion identifies the specific device within that network. The /28 notation indicates that the first 28 bits of the IP address are dedicated to the network portion, leaving the remaining bits for the host portion. This notation is used in subnetting to divide a network into smaller subnetworks.

Given the network mask id of 255.255.240.0, how many hosts are there?
Correct Answer
B. 4094
9.
What is the broadcast address for the network in which 192.168.242.5/20 is located?
Correct Answer
C. 192.168.255.255
Explanation
The given IP address 192.168.242.5/20 has a subnet mask of 20 bits, which means the first 20 bits of the IP address represent the network portion. To find the broadcast address, we need to set all the host bits (bits after the subnet mask) to 1. In this case, since the subnet mask is /20, the first 20 bits remain unchanged, and the remaining 12 bits (32 total bits - 20 subnet mask bits) are set to 1. Therefore, the broadcast address is 192.168.255.255.
10.
What is the net ID for the network in which 192.168.242.5/20 is located?
Correct Answer
B. 192.168.240.0
Explanation
The net ID for the network in which 192.168.242.5/20 is located is 192.168.240.0.
