Question: In the context of OSCORE Ua protocol payload encoding for efficient information transfer between constrained IoT devices in a Generic Authentication Architecture (GAA), what is the specified CoAP Content-Format for CBOR encoding?
Option 1: CoAP Content-Format: 50
Option 2: CoAP Content-Format: 55
Option 3: CoAP Content-Format: 60
Option 4: CoAP Content-Format: 65
Explanation: The correct answer is based on the standardization of media types and content formats for efficient data transfer in constrained networks. In this context, CBOR (Concise Binary Object Representation) encoding is utilized for its efficiency. According to the specified guidelines for OSCORE Ua protocol payload encoding, the CoAP Content-Format assigned for CBOR encoding is indeed 60, highlighting the importance of standardized formatting for seamless communication between IoT devices in a GAA framework.
