IETF's Focus:The Internet Engineering Task Force (IETF) primarily develops and standardizes internet protocols operating at the Network Layer (Layer 3) and above in the OSI model.

Key Protocols:Some prominent IETF-developed protocols include:

IP (Internet Protocol):Foundation of internet addressing and routing.

TCP (Transmission Control Protocol):Reliable, connection-oriented data transport.

UDP (User Datagram Protocol):Connectionless, best-effort data transport.

DNS (Domain Name System):Translates domain names into IP addresses.

HTTP (Hypertext Transfer Protocol):Web communication.

I thought the IETF was more about the upper layers, but I can't recall if they touch on the Data Link Layer at all.

I feel like I saw a practice question that mentioned the IETF's work on the Transport Layer, so maybe it's all layers?

I remember studying that the IETF deals with protocols, which makes me lean towards option C.
