Final answer:
Option 4 is correct.DHCP (Dynamic Host Configuration Protocol) is the protocol that allows for the automated discovery of networked services on LANs by dynamically assigning IP addresses and network configuration to devices.
Step-by-step explanation:
The protocol that permits automated discovery of networked services on Local Area Networks (LANs) is DHCP (Dynamic Host Configuration Protocol). DHCP allows computers and other devices to join a network without requiring manual configuration of an IP address. Instead, devices connected to the network receive an IP address and other network configuration details such as the subnet mask, default gateway, and DNS servers from a DHCP server. This process is known as dynamic IP address assignment and is essential for the scalability and ease of management of modern networks.
While TCP/IP represents the suite of communication protocols used across the internet and LANs, it is not specifically responsible for the automated discovery of networked services. HTTP (Hypertext Transfer Protocol) is the protocol used for transferring web pages across the internet, not for the discovery of services on a LAN. DNS (Domain Name System) translates domain names into IP addresses but does not assign IP addresses on a LAN.
