CCNA: Cisco Certified Network Associate — Question 225

Which function does an SNMP agent perform?

Answer options

• A. It sends information about MIB variables in response to requests from the NMS
• B. It manages routing between Layer 3 devices in a network
• C. It coordinates user authentication between a network device and a TACACS+ or RADIUS server
• D. It requests information from remote network nodes about catastrophic system events

Correct answer: A

Explanation

The correct answer is A, as the SNMP agent is responsible for sending MIB variable information back to the Network Management System (NMS) upon request. Options B and C describe functions related to routing and user authentication, which are not the roles of an SNMP agent. Option D incorrectly states that the agent requests information, while it actually responds to requests.
