What is the main function of a Network Interface Card (NIC)?

• To allow a computer to connect to a network

• To store IP addresses of devices on the network

• To forward data packets between networks

• To encrypt data before transmission

A Media Access Control (MAC) address is used to:

• Uniquely identify a device on a network

• Assign an IP address to a device

• Encrypt network traffic for security

• Improve internet speed on a device

Which of the following statements is true about MAC addresses?

• They are assigned to a device at manufacture and do not change

• They are dynamically assigned by the router each time a device connects

• They are written in decimal format like an IPv4 address

• They consist of 64 bits divided into two halves

What is the main difference between an IPv4 address and an IPv6 address?

• IPv4 uses 32 bits, while IPv6 uses 128 bits

• IPv6 is used only for local networks, while IPv4 is for the internet

• IPv4 addresses are static, while IPv6 addresses are dynamic

• IPv6 provides slower data transmission than IPv4

Which of the following is an example of an IPv4 address?

• 192.168.1.1

• 2001:0db8:85a3:0000:0000:8a2e:0370:7334

• 00:1A:2B:3C:4D:5E

• 255.255.255.255

What is a static IP address?

• A fixed IP address that does not change

• An IP address that is assigned temporarily by a network

• A MAC address that is converted into an IP address

• An IPv6 address used for private networks

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

• To forward data packets between networks

• To generate and assign MAC addresses to devices

• To store and process websites locally

• To boost the Wi-Fi signal of a device

Which of the following is not a function of a router?

• Assigning MAC addresses to devices

• Forwarding data between networks

• Assigning IP addresses using DHCP

• Connecting a local network to the internet

A router assigns dynamic IP addresses using which protocol?

• DHCP (Dynamic Host Configuration Protocol)

• TCP (Transmission Control Protocol)

• HTTP (Hypertext Transfer Protocol)

• FTP (File Transfer Protocol)

Which of the following best describes an IPv6 address?

• A 128-bit address written in hexadecimal format

• A 32-bit address used only for local networks

• A MAC address assigned to every network device

• An IPv6 address used for private networks
