When a Juniper Mist managed switch is powered on, which event must be completed prior to the Zero-Touch Provisioning (ZTP) process moving forward?

The Zero-Touch Provisioning (ZTP) process for a Juniper Mist managed switch requires the switch to connect to the Mist cloud to download its configuration. The first step to achieving network connectivity is for the switch to obtain an IP address, default gateway, and DNS server information. This is accomplished by requesting and receiving a lease from a DHCP server on the local network. Without a successful DHCP lease, the switch cannot resolve the Mist cloud address or communicate on the network, halting the ZTP process.

A. User accounts are configured after the switch is onboarded and managed by Mist; they are not a prerequisite for the initial ZTP process.

C. NETCONF is the protocol Mist uses to configure the switch, but it is enabled and configured by the ZTP process, not before it.

D. While NTP synchronization is important, the switch must first obtain network connectivity via DHCP to be able to reach an NTP server.
