What is the purpose of a default gateway in a network configuration?

• To slow down network traffic within the local network

• To route network traffic to other networks or the internet.

• To block network traffic from reaching other networks

Explain the difference between a static IP address and a dynamic IP address.

• A static IP address is manually assigned to a device and does not change, while a dynamic IP address is automatically assigned by a DHCP server and can change over time.

• A static IP address is used for mobile devices, while a dynamic IP address is used for stationary devices.

• A static IP address is automatically assigned by a DHCP server and can change over time.

• A dynamic IP address is manually assigned to a device and does not change.

What is the function of a subnet mask in network configuration?

• It is used to assign a unique identifier to each device on the network

• It is used to divide an IP address into network and host portions.

• It is used to encrypt data transmission

• It is used to determine the speed of the network connection

Describe the process of configuring a computer to use a specific DNS server.

• Unplug the computer and plug it back in to reset the DNS server

• Ask the IT department to configure the DNS server for you

• Manually enter the IP address of the DNS server in the TCP/IP settings.

What is the role of DHCP in network configuration?

• Manually assign IP addresses to devices on a network

• Control the flow of network traffic

• Encrypt data transmission on the network

• Automatically assign IP addresses and other network configuration information to devices on a network

Explain the concept of port forwarding and its significance in network connectivity.

• Port forwarding is only necessary for wired networks

• Port forwarding is used to block access to devices behind a firewall

• Port forwarding has no impact on network connectivity

• Port forwarding allows for remote access to devices or services behind a firewall or NAT router.

What are the common methods for securing a wireless network?
