Question 1

What SNMP version provides encryption and authentication, making it the most secure option supported by SolarWinds NPM?

Accepted Answer

SNMPv3

Answer

SNMPv3 introduces user-based security with MD5/SHA authentication and DES/AES encryption, unlike the community-string-based v1/v2c.

Question 2

In SolarWinds, a 'node down' alert is generated based on which underlying check?

Accepted Answer

ICMP ping response failure

Answer

SolarWinds uses ICMP echo requests (ping) to determine node availability; consecutive failures trigger a node-down alert.

Question 3

Which SolarWinds polling engine component handles data collection from monitored nodes and is distinct from the main web server?

Accepted Answer

Additional Polling Engine (APE)

Answer

APEs distribute polling load across multiple servers, allowing SolarWinds to scale monitoring to tens of thousands of nodes.

Question 4

What SolarWinds feature captures and stores syslog and SNMP trap messages for event correlation and troubleshooting?

Accepted Answer

Syslog and Trap Viewer

Answer

The Syslog and Trap Viewer in Orion collects unsolicited messages from devices, enabling correlation with monitored metrics.

Question 5

In SolarWinds NPM, what metric represents the percentage of transmitted packets that did not reach their destination?

Accepted Answer

Packet loss percentage

Answer

Packet loss percentage is calculated from ICMP probes or interface counters and indicates network path quality.
