In ZTP networking, which of the following addresses can be delivered by a DHCP server? (Select All that Apply)

During Zero Touch Provisioning (ZTP), a network device uses DHCP to obtain essential information to connect to the network and the management system. The DHCP server provides the device with a temporary management IP address (D) and subnet mask. It also provides the default gateway address (A) to enable communication outside its local subnet and the DNS server address (C) to resolve hostnames, such as the controller's FQDN. These are fundamental parameters for initial network connectivity.

B. While the address of a file server (which could use SFTP) is critical for ZTP, it is typically delivered via a vendor-specific DHCP option (e.g., Huawei uses Option 148), not a standard, universally defined address option like gateway or DNS.

1. Huawei CloudEngine Series Switches Configuration Guide - "ZTP Configuration." This guide specifies the DHCP options required for ZTP, including standard options for IP address, gateway (Option 3), and DNS (Option 6).

2. RFC 2132, "DHCP Options and BOOTP Vendor Extensions." This standard defines Option 3 (Router Option) for the default gateway and Option 6 (Domain Name Server Option) for DNS servers. It does not define a standard option for an SFTP server.
