   An automation team is writing a Python script that uses the Junos PyEZ library to push configuration changes to multiple Junos devices. The script connects to each device, loads the configuration, and commits it. Which statement accurately describes how PyEZ interacts with MGD to accomplish this?

   • APyEZ uses SNMP to send configuration changes directly to the configuration database, bypassing MGD.
   • BPyEZ uses NETCONF to send the configuration to MGD, which validates and applies it to the candidate configuration, then commits it.
   • CPyEZ uses the CLI to send configuration commands to MGD, which then applies them.
   • DPyEZ uses REST API to send configuration changes directly to the forwarding plane, which then updates the configuration database.
