A small business has a SOHO router with a single public IP address from the ISP. The office has 15 computers that all need to access the internet simultaneously. The router is already performing NAT. What is the primary reason this setup works without needing 15 public IP addresses?

NAT translates the private IP addresses of the internal devices to the single public IP address for outbound traffic.

The computers use IPv6 link-local addresses to communicate directly with the internet.

The router assigns each computer a unique public IP address from the ISP's pool.

The router uses DNS to translate the private addresses into the public address.

A SOHO network uses DHCP to assign IP addresses. A user reports that their computer cannot connect to the internet, but other devices on the same network work fine. The computer's IP address is 169.254.12.34. What is the most likely cause?

The computer's subnet mask is incorrect.

The router's DHCP pool is exhausted.

The computer's DNS server is misconfigured.

The computer failed to obtain an IP address from the DHCP server.

In a SOHO network, what is the primary function of a network switch?

To provide wireless connectivity to devices

To route traffic between different IP subnets

To connect the LAN to the internet service provider

To connect multiple devices within the same LAN and forward data based on MAC addresses
