Answer options

• A. UDP

Correct answer: C

Explanation

The correct answer is C, SNMP, which is a protocol designed to manage and monitor network devices at the application layer (Layer 7) of the OSI model. Options A (UDP) and B (MAC) operate at lower layers; UDP functions at Layer 4 (Transport) and MAC operates at Layer 2 (Data Link). Option D (NFS) is also an application layer protocol, but SNMP is more specifically associated with network management.
