SolarWinds Updated SCP-NPM Exam Questions and Answers by carla

Universal Device Pollers (UnDPs) are custom pollers that allow you to monitor specific aspects of your network devices using SNMP. You can apply UnDPs to any object type that supports SNMP polling, such as interfaces, nodes, and volumes. You cannot apply UnDPs to applications, because they are not SNMP-based objects. Applications are monitored using Application Performance Monitor (APM), which uses different methods, such as WMI, scripts, or agents, to collect data. References: Monitor custom statistics based on OIDs with Universal Device Pollers in NPM, Assign Universal Device Pollers to devices monitored in NPM, Add and assign Universal Device Pollers

You can make bulk changes to nodes in NPM using the Manage Nodes feature. This allows you to select multiple nodes and edit their properties, such as the polling method, the polling frequency, the SNMP credentials, the custom properties, and more. You can also use the Edit Nodes feature to assign or unassign pollers to nodes, such as the Universal Device Poller (UnDP), the Hardware Health Poller, the Wireless Poller, and more12. References: 1: Change the polling method for a node3, 2: Manage pollers using Device Studio4

 Traps are unsolicited messages sent by network devices to report events or issues. The Orion Platform can receive and process traps from any device that supports SNMP. To alert on a select message, you can use the Traps in Orion Alerts feature, which allows you to configure the default trap alert to fire on the trap message you select to alert on. You can also customize the alert conditions, actions, and triggers to suit your needs. For example, you can alert on traps thatmatch a specific OID, source, or severity, and send an email, log a ticket, or run a script when the alert is triggered. References: Configure SNMP traps in NPM, Traps in Orion Alerts, Create alerts for SNMP traps

For any node you monitor, you cannot use Network Discovery to automatically add child volumes or interfaces for monitoring. Network Discovery is a tool that helps you identify and add new devices to your network, but it does not automatically monitor all the components of the discovered devices. You need to manually select the volumes or interfaces you want to monitor from the list of resources on each node. You can also use the Network Sonar Results Wizard to filter and add the resources you want to monitor after running a discovery job. References:
