Question 1

What SolarWinds feature allows you to view the path packets take between two network endpoints and measure per-hop latency?

Accepted Answer

Path Analysis / NetPath

Answer

NetPath (Path Analysis) performs continuous hop-by-hop probing, displaying latency and loss at each point along the network path.

Question 2

Which SolarWinds Orion module would you use to monitor Quality of Service (QoS) markings and queuing on WAN interfaces?

Accepted Answer

IP SLA Manager / QoS Monitor

QoS Monitor (part of IP SLA) tracks DSCP markings, queue depths, and drops to verify QoS policy effectiveness on WAN links.

Question 3

In SolarWinds, what is the role of 'UnDP' (Universal Device Pollers)?

Accepted Answer

Poll any custom OID not natively supported by NPM

Answer

UnDPs allow administrators to define custom SNMP OID polls so Orion can collect vendor-specific metrics beyond its built-in poller library.

Question 4

What SolarWinds report type aggregates node availability over a defined period, expressed as an uptime percentage?

Accepted Answer

Availability report

Answer

Availability reports calculate the ratio of up-time to total monitoring time for each node, commonly used for SLA documentation.

Question 5

When SolarWinds issues a 'high CPU' alert on a router, what underlying SNMP MIB object is typically being polled?

Accepted Answer

ciscoProcessMIB or hrProcessorLoad

Answer

CPU utilization is read from vendor-specific OIDs (e.g., Cisco's cpmCPUTotalTable) or the standard HR-MIB hrProcessorLoad object.
