A network administrator is reviewing telemetry and alerting mechanisms across enterprise Cisco routers. Which TWO statements accurately describe the operational differences between SNMP traps and SNMP informs? (Select TWO.)
- SNMP traps are unacknowledged notification messages sent asynchronously by managed devices to an SNMP management station over UDP port 162.Answer
- SNMP informs require the receiving SNMP manager to acknowledge receipt of the notification, providing reliable delivery confirmation to the sending device.Answer
- CSNMP traps establish a connection-oriented TCP session on port 161 to ensure retransmission of dropped event messages.
- DSNMP informs use Syslog severity levels (0 through 7) to determine whether an acknowledgement from the manager is required.
Answer
SNMP traps are unacknowledged notifications sent over UDP port 162, while SNMP informs require an explicit acknowledgement from the receiving SNMP management station to confirm delivery.
SNMP traps are unacknowledged notifications sent to UDP port 162 on the management station. In contrast, SNMP informs provide reliable delivery by requiring the manager to respond with an acknowledgement PDU.
