  1. Which SNMP version introduced strong authentication and encryption for secure network management?

    Answer: SNMPv3

    SNMPv3 added user-based security with MD5/SHA authentication and DES/AES encryption, unlike the community-string-based v1 and v2c.

  2. A Cisco device sends an unsolicited SNMP message to the NMS when an interface goes down. What is this message called?

    Answer: SNMP Trap

    An SNMP Trap is an unsolicited notification sent from the agent to the NMS when a significant event occurs.

  3. What is the purpose of the Management Information Base (MIB) in SNMP?

    Answer: Defines the hierarchical database of managed objects on a device

    The MIB is a structured database that defines all the variables (objects) that can be monitored or configured via SNMP.

  4. Which protocol and port does SNMP use for NMS-to-agent queries?

    Answer: UDP port 161

    SNMP uses UDP port 161 for NMS-to-agent queries (Get/Set), while traps and informs use UDP port 162.

  5. An administrator uses 'snmp-server community PUBLIC ro' in global config. What does 'ro' specify?

    Answer: Read-only access — the NMS can only retrieve data, not modify it

    The 'ro' keyword grants read-only community access, allowing the NMS to perform Get operations but not Set operations.

  6. Which command on a Cisco router verifies that SNMP is enabled and shows configured community strings?

    Answer: show snmp community

    The 'show snmp community' command displays all configured SNMP community strings and their access levels.

  7. A technician uses Cisco IOS NetFlow on a router interface. What is the primary purpose of NetFlow?

    Answer: Collect and export IP traffic statistics for analysis and accounting

    NetFlow collects detailed per-flow traffic statistics (source/destination IP, ports, protocol) and exports them to a collector for analysis.
