A network engineer must back up 20 network router configurations globally within a customer environment. Which protocol allows the engineer to perform this function using the Cisco IOS MIB?
SNMP is the protocol associated with IOS MIB access and centralized network management. The Management Information Base is the structured set of managed objects that an SNMP manager can query or, where permitted, modify on an SNMP agent. In the context of backing up many router configurations globally, SNMP can be used by management software to interact with Cisco IOS MIB objects and trigger configuration-copy operations. CDP discovers directly connected Cisco neighbors; it is not a configuration backup protocol. SMTP is for mail transfer. ARP resolves IPv4 addresses to MAC addresses on a local segment. Cisco CCNA v1.1 IP Services includes device management protocols such as SNMP, syslog, and NTP. The important distinction is scope: SNMP gives a management station structured visibility and control through MIB objects across many devices. That is why the Cisco IOS MIB clue points directly to SNMP.
