Which of the following is an appropriate reason for adjusting the SNMP thresholds?

SNMP thresholds define the limits for monitored parameters, and adjusting them higher can prevent the system from generating an excessive number of alerts for minor, non-critical events or normal operational fluctuations, thus reducing alert fatigue. By setting thresholds appropriately, administrators can focus on genuinely critical issues that warrant attention.

SNMP thresholds are configuration parameters for monitoring and alerting, and do not directly control or increase the number of threads an application or system uses.

While SNMP can collect data related to VPN traffic, adjusting thresholds is about when to trigger an alert based on monitored data, not about enabling or initiating the monitoring of VPN traffic itself.

SNMP is a protocol for network device management and monitoring, and has no direct function in allowing or disallowing email to come through an email server.
