Answers

D.
NETCONF layers use the operations layer to send RPCs to a remote NETCONF server.
Answers
D.
NETCONF layers use the operations layer to send RPCs to a remote NETCONF server.
Suggested answer: B, C

Explanation:

NETCONF (Network Configuration Protocol) is a standard protocol defined for managing network devices. NETCONF operates in a layered architecture, which includes the following key layers:

Operations Layer: This layer deals with the actual operations like <get-config>, <edit-config>, <copy-config>, and others. It receives RPC (Remote Procedure Call) requests from a remote NETCONF client and processes these requests.

Messages Layer: This layer is responsible for encoding the RPCs and sending them over the network. It handles the communication between the NETCONF client and server, ensuring that the RPC messages are correctly formatted (usually in XML) and transmitted.

Statement B is correct because the Messages layer is responsible for sending RPCs to a remote NETCONF server.

Statement C is correct because the Operations layer is where the NETCONF server receives and processes the RPCs sent by the client.
