Which two processes are involved when BIG-IP systems issue traps? (Choose two.)

bigd is the health monitor daemon that checks pool member and node availability; it is not part of the SNMP trap generation or alert notification subsystem.

The alertd daemon continuously monitors the BIG-IP alert pipeline and is the process directly responsible for evaluating alert conditions and issuing SNMP traps when thresholds or events are triggered, making it a required participant in trap generation.

smtpd handles outbound email (SMTP) alert notifications and operates independently from the SNMP trap subsystem, serving a different notification channel entirely.

syslog-ng receives log messages from BIG-IP subsystems and routes relevant events to alertd for evaluation - the two daemons form a pipeline where syslog-ng provides the log input and alertd acts on it to produce SNMP traps.
