Default Gateway Verification

A home user is unable to get to the Internet from a workstation that is connected to a wireless network.

When reviewing the results of the ipconfig command, the user wants to verity the default gateway is correct.

Which of the following devices should be the gateway?

A.

Cable modem

B.

SOHO router

C.

DNS server

D.

Layer 2 switch.

A.

The correct answer is B. SOHO router.

In this scenario, the home user is unable to connect to the Internet from a workstation that is connected to a wireless network. The problem is most likely related to the default gateway settings on the workstation, which is preventing the workstation from accessing resources outside the local network.

The default gateway is the IP address of the router that connects the local network to the Internet. When a device on the local network needs to access resources outside the network, it sends packets to the default gateway, which forwards the packets to the appropriate destination on the Internet.

The ipconfig command displays the IP address configuration of the network interfaces on the workstation, including the IP address, subnet mask, and default gateway. To verify that the default gateway is correct, the user should check the IP address of the default gateway and ensure that it matches the IP address of the router that connects the local network to the Internet.

In this scenario, the correct device that should be the gateway is a SOHO (Small Office/Home Office) router. This type of router is designed for use in small offices or home networks and includes built-in wireless access points for connecting wireless devices to the network. The SOHO router is responsible for routing packets between the local network and the Internet, and its IP address should be configured as the default gateway on the workstation.

The other options listed in the answer choices are not appropriate gateway devices in this scenario:

• Cable modem: A cable modem is a device that provides Internet access to a network by connecting to a cable television network. While a cable modem is required to connect to the Internet, it is not responsible for routing packets between the local network and the Internet.

• DNS server: A DNS (Domain Name System) server is a network service that translates domain names into IP addresses. While DNS servers are essential for accessing resources on the Internet, they are not responsible for routing packets between the local network and the Internet.

• Layer 2 switch: A layer 2 switch is a network device that forwards frames between network devices based on their MAC addresses. While layer 2 switches are important for connecting devices on a local network, they are not responsible for routing packets between the local network and the Internet.
