ICND1 Network Fundamentals & IP Addressing

Question 1

What is the purpose of the IP address in networking?

Accepted Answer

To identify and locate devices on a network

Answer

An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network. Its fundamental purpose is to identify and locate these devices within the network, enabling them to communicate with each other and exchange data.

Question 2

Which of the following is a private IP address?

Accepted Answer

192.168.1.1

Answer

Private IP addresses are specifically reserved for use within local networks and are not routable on the public internet. The range 192.168.0.0 to 192.168.255.255 is one of the designated private IP address ranges, making 192.168.1.1 a classic example used in many home and office networks.

Question 3

What does a subnet mask do in networking?

Accepted Answer

It divides the IP address into network and host parts

Answer

A subnet mask is a 32-bit number that works in conjunction with an IP address to define the network and host portions of the address. It helps devices determine if a destination IP address is on the same local network or if it needs to be routed to a different network, facilitating efficient data transmission.

Question 4

What is the main difference between IPv4 and IPv6?

Accepted Answer

IPv6 has longer addresses and more available IP addresses

Answer

The primary difference between IPv4 and IPv6 lies in their address length and the number of available IP addresses. IPv4 uses 32-bit addresses, which are nearly exhausted, while IPv6 uses 128-bit addresses, providing a vastly larger address space to support the growing number of internet-connected devices.

Question 5

Which protocol is used to map an IP address to a MAC address on a local network?

Accepted Answer

ARP

Answer

ARP (Address Resolution Protocol) is a crucial protocol used on local networks to map an IP address to its corresponding MAC (Media Access Control) address. When a device needs to communicate with another device on the same segment, it uses ARP to discover the physical MAC address associated with the destination's logical IP address.
