Question 1: What is the primary purpose of a network switch?
- To connect multiple networks together
- To route traffic between different IP networks
- To connect devices within the same network and forward data to the correct device (Correct answer)
- To assign IP addresses to devices in a network
Correct answer: To connect devices within the same network and forward data to the correct device
A network switch operates at the data link layer (Layer 2) and is used to connect devices within a LAN, directing data to its intended destination.
Question 2: Which device is used to connect different networks and direct data between them?
- Switch
- Router (Correct answer)
- Hub
- Modem
Correct answer: Router
A router operates at the network layer (Layer 3) and is responsible for routing data between different IP networks.
Question 3: What does the term "IP address" stand for?
- Internet Protocol address (Correct answer)
- Internal Protocol address
- Interconnected Protocol address
- Intranet Protocol address
Correct answer: Internet Protocol address
An IP address is a unique address that identifies a device on the internet or a local network.
Question 4: Which protocol is used to automatically assign IP addresses to devices on a network?
- DNS
- HTTP
- DHCP (Correct answer)
- FTP
Correct answer: DHCP
Dynamic Host Configuration Protocol (DHCP) is used to automatically assign IP addresses and other network configuration parameters to devices on a network.
Question 5: What is the purpose of a subnet mask in an IP network?
- To hide the IP address of devices on a network
- To distinguish between the network and host portions of an IP address (Correct answer)
- To encrypt data before it is sent over the network
- To assign MAC addresses to devices
Correct answer: To distinguish between the network and host portions of an IP address
A subnet mask is used to divide an IP address into a network and host portion, determining which part of the address refers to the network and which part refers to the specific device.
