CCNA: Cisco Certified Network Associate — Question 38

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?

Answer options

• A. ARP
• B. SNMP
• C. SMTP
• D. CDP

Correct answer: B

Explanation

The correct answer is B, SNMP (Simple Network Management Protocol), which is designed for managing network devices and can be used to retrieve configuration data from routers. The other options, such as ARP (Address Resolution Protocol) and SMTP (Simple Mail Transfer Protocol), serve different purposes and do not facilitate the backup of router configurations, while CDP (Cisco Discovery Protocol) is primarily for discovering Cisco devices on a network.
