What protocol allows an engineer to back up 20 network router configurations globally while using the copy function?
Correct Answer: B
The protocol being tested is SNMP, because the question describes backing up many router configurations globally through a management mechanism tied to Cisco IOS MIB behavior. SNMP uses a manager-agent model and a Management Information Base to expose manageable objects on network devices. Through supported MIB objects and management tooling, an engineer can trigger or coordinate operations across many devices instead of manually logging into each router. SMTP is mail transport, not router configuration backup. TCP is a transport protocol, not the management protocol being selected here. FTP can transfer files, but the wording about global backup using the copy function in this exam item is aimed at SNMP-based management through Cisco IOS MIB support. Cisco CCNA 200-301 v1.1 IP Services includes SNMP because monitoring and management are core operational services. The correct answer is B: SNMP. In practical operations, the file transfer target may still use a file service, but the management protocol controlling the function is SNMP.
