Explanation

SNMP (Simple Network Management Protocol) operates at Layer 7 (Application) of the OSI model; it is used to monitor and manage network devices. UDP is a Transport layer (Layer 4) protocol. MAC (Media Access Control) addresses belong to the Data Link layer (Layer 2). NFS (Network File System) is also an Application-layer protocol, but SNMP is the most precisely and unambiguously classified Layer 7 protocol among these choices and is the intended answer.
