What command must you use to enable trap sending in SNMP?

1. (config)#snmp-server enable traps

2. (config)#snmp-server trap enable

3. (config)#set traps enabled

4. (config)#snmp-trap activate

The correct answer is: (config)#snmp-server enable traps

The command to enable trap sending in Simple Network Management Protocol (SNMP) is indeed "snmp-server enable traps." This command configures the SNMP agent on a device to send notifications (traps) to the SNMP manager, informing it about significant events or thresholds that have been met on the network device. When you execute this command, you're allowing the device to actively communicate alerts and status information to the SNMP manager, which is crucial for network monitoring and management. This functionality is part of the SNMP framework, which operates based on a request-response model, but traps add an additional layer by allowing the agent to send unsolicited messages. Other commands mentioned do not align with the recognized syntax used in Cisco IOS for enabling traps. For example, "snmp-server trap enable" and "set traps enabled" do not correspond to any standard command used for configuring SNMP traps, and "snmp-trap activate" is also not a valid command in Cisco's configuration guidelines.
