ACP Networking Fundamentals

Question 1

What is the primary function of a router in a network?

Accepted Answer

Route traffic between networks

Answer

A router's primary function is to connect different networks and forward data packets between them. It uses IP addresses to determine the best path for data to travel from a source network to a destination network. This enables communication between devices on separate local area networks (LANs) and the internet.

Question 2

Which protocol is used to assign IP addresses dynamically?

Accepted Answer

DHCP

Answer

DHCP, or Dynamic Host Configuration Protocol, is a network management protocol used on Internet Protocol (IP) networks for dynamically assigning IP addresses and other communication parameters to devices connected to the network. This automation simplifies network administration by eliminating the need for manual IP configuration for each device, ensuring efficient network operation.

Question 3

What is the function of a switch in a network?

Accepted Answer

Directs traffic within a LAN

Answer

A network switch operates within a Local Area Network (LAN) to connect multiple devices, such as computers, printers, and servers. Its function is to efficiently direct data traffic only to the specific device for which it is intended, based on MAC addresses. This intelligent forwarding improves network performance by reducing unnecessary traffic compared to a hub.

Question 4

Which of the following is a private IP address?

Accepted Answer

192.168.1.1

Answer

Private IP addresses are reserved for use within private networks and are not routable on the public internet. The Internet Assigned Numbers Authority (IANA) has reserved specific IP address ranges for this purpose, which include 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. Therefore, 192.168.1.1 falls within one of these designated private ranges, commonly used in home and small office networks.

Question 5

What does DNS stand for?

Accepted Answer

Domain Name System

Answer

DNS stands for Domain Name System. It is a hierarchical and decentralized naming system for computers, services, or any resource connected to the Internet or a private network. DNS translates human-readable domain names (like google.com) into numerical IP addresses that computers use to identify each other, acting like the internet's phonebook.
