Concepts of TCP/IP and the Link Layer

For a host to communicate successfully with the Internet, which network protocols are required? Assume users will not manually configure the computer in any way, and success is measured by whether a user can access websites after powering on the computer and signing in.

Each correct answer represents a complete solution. Choose all that apply.

Choose three
  • A DNS
  • B HTTP/HTTPS
  • C DHCP
  • D NTP
Explanation

DHCP automatically provides the host’s network configuration, including an IP address, subnet mask, default gateway, and typically DNS server settings. DNS resolves website names to IP addresses, and HTTP/HTTPS is used to retrieve website content. NTP synchronizes time but is not required to establish web access.
