C. DNS DNS (Domain Name System) is responsible for translating domain names (like [invalid URL removed]) into IP addresses that computers can understand. If the DNS settings on the laptop are incorrect or not configured, the device won't be able to resolve domain names and access websites. Since the laptop's IP address changed to DHCP, it likely lost its previous DNS configuration. The technician needs to ensure that the laptop is configured to use the correct DNS servers, either manually or through DHCP. Google Gemini
