Which communication mechanism does NETCONF use?

The correct answer is D. RPC over SSH. NETCONF primarily uses Remote Procedure Calls (RPCs) over a secure transport protocol like SSH to facilitate configuration and management of network devices.

Why each option

NETCONF primarily uses Remote Procedure Calls (RPCs) over a secure transport protocol like SSH to facilitate configuration and management of network devices.

ASOAP over HTTPS

SOAP over HTTPS is a common web service communication method but is not the underlying mechanism used by NETCONF.

BYAML over SSH

YAML (YAML Ain't Markup Language) is a data serialization format, not the communication mechanism, and while SSH is used, YAML is not the standard data format for NETCONF.

CYAML over HTTPS

YAML over HTTPS combines a data serialization format with a secure transport, but NETCONF uses RPCs over SSH, not YAML over HTTPS.

DRPC over SSHCorrect

NETCONF defines a mechanism for remote procedure calls (RPCs) to perform operations on network devices, and these RPC messages are transported reliably and securely over SSH (Secure Shell) as the standard transport mapping.
