A network engineer wants to allow devices on the network to automatically receive network configuration parameters and to map domain names to their corresponding numerical identifiers. Which combination of services should the engineer configure?
To enable devices to automatically receive network configuration parameters, the engineer should configure the Dynamic Host Configuration Protocol (DHCP). DHCP automates the assignment of IP addresses, subnet masks, gateways, and other network settings to client devices. To map domain names to numerical identifiers (IP addresses), the engineer should set up the Domain Name System (DNS). DNS translates human-readable domain names into IP addresses, allowing users to access resources using easy-to-remember names instead of numeric addresses. Together, DHCP and DNS facilitate seamless network connectivity and user-friendly resource access. Other options like SMTP (Simple Mail Transfer Protocol), ARP (Address Resolution Protocol), FTP (File Transfer Protocol), NAT (Network Address Translation), SNMP (Simple Network Management Protocol), and ICMP (Internet Control Message Protocol) do not fulfill both requirements.
