Question: An RFC is labeled ________ if it must be implemented by all Internet systems.

Answer:

An RFC (Request for Comments) is labeled a "Internet Standard" if it must be implemented by all Internet systems.
Internet Standards are the highest level of standardization in the Internet standards process. They are protocols or standards that have been subjected to extensive review, testing, and implementation, and are considered to be stable and suitable for widespread deployment.
Internet Standards are required to be implemented by all Internet systems, and they represent the consensus of the Internet community on the best practices and protocols for ensuring interoperability and reliable operation of the Internet.
Internet Standards are designated by the Internet Engineering Task Force (IETF), the organization responsible for developing and maintaining the protocols and standards that govern the operation of the Internet. RFCs are the documents used by the IETF to publish proposed standards, draft standards, and Internet standards.
