To dynamically assign IP addresses, which server role must be implemented?

• A. RAS
• B. DNS
• C. DHCP
• D. WINS

Answer: (C)

To dynamically assign IP addresses, the server role that must be implemented is the Dynamic Host Configuration Protocol (DHCP). DHCP automates the process of IP address assignment, allowing devices on a network to request and receive IP addresses from a DHCP server automatically. This reduces the need for manual configuration of IP addresses on each individual device, which can be time-consuming and error-prone. DHCP operates by leasing an IP address to a device for a specific period, called a lease time. When the lease expires, the device can either renew its lease or request a new IP address. This ensures efficient use of IP address space, particularly in environments with many devices that may not always be connected to the network. In contrast, RAS (Remote Access Service) facilitates remote access to a network but does not assign IP addresses. DNS (Domain Name System) is responsible for translating domain names into IP addresses, helping devices find each other on the network. WINS (Windows Internet Naming Service) helps resolve NetBIOS names to IP addresses on a network, primarily in legacy systems but does not play a role in dynamically assigning IP addresses. Thus, DHCP is the essential server role for dynamically assigning IP addresses within a network.
