Which two network services are required for zero-touch (PNP/ZTP) onboarding? (Choose two.)

DHCP (Dynamic Host Configuration Protocol) is essential for zero-touch provisioning because it automatically assigns IP addresses to new devices, allowing them to connect to the network without manual configuration. DNS (Domain Name System) is also critical as it translates human-readable domain names (like ztp.cisco.com) into IP addresses, enabling devices to locate and communicate with the Cisco PnP/ZTP server. Without both DHCP and DNS, the device cannot obtain network connectivity or find the necessary provisioning server to complete the onboarding process. EMAIL, SNMP, and AAA are not directly involved in the initial network connectivity and server discovery phases of zero-touch provisioning.
