NEW QUESTION # 72
Some of the flows received are mapping to an IP address that does not match any of the nodes being monitored. It has been verified that all flow sources are also being monitored by NPM and SNMP polling.
The known source nodes for these flows have the correct IP address. What could be causing this issue?
- A. Flows are coming from a non-primary address and the setting to match the node by another IP is turned off
- B. Source machine field in the flows is not configured and the setting to match the node by another IP is turned off
- C. Flows are IPv6 and the network monitoring does not recognize that version
- D. IP address for the node is incorrect in SNMP polling but correct in the flows
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
SolarWinds NTA maps flow sources to nodes by matching the IP address. If a device exports flows using a secondary IP (not the one defined as "primary" in SolarWinds), and the setting "Allow matching by other IPs" is not enabled, the flow will not map to a known node. The documentation explains:
"If flow packets are received from an IP address not designated as primary in SolarWinds, and matching by other IPs is disabled, the flow source is not linked to a node. Enable the setting to match by any device IP to resolve this issue." References:
Network Performance Monitor Administrator Guide, "Flow Source Matching and IP Address Mapping" SolarWinds NTA documentation

NEW QUESTION # 77
Probing interval determines how often and how long information is polled from the network path. Which two of the following statements are true regarding probing intervals? (Choose two.)
- A. Probing less frequently allows the data to update more slowly and increases data accuracy
- B. Probing more frequently allows the data to update faster but decreases data accuracy
- C. Probing less frequently allows the data to update faster but decreases data accuracy
- D. Probing more frequently allows the data to update more slowly and increases data accuracy
Answer: A,B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
A). When you probe less frequently, updates are slower but generally more accurate since there's less overhead and less chance of missing network changes due to polling overlaps.
C). Probing more frequently results in faster updates but may slightly decrease accuracy due to increased network noise and overlapping probes.
The documentation states:
"A higher probing frequency provides faster updates in NetPath views but can reduce accuracy due to more frequent sampling. Lower frequency means slower updates but typically results in higher accuracy and less system load." References:
Network Performance Monitor Administrator Guide, "NetPath Probing Interval Best Practices" SolarWinds Success Center: "Optimizing NetPath Probing Intervals"

NEW QUESTION # 84
A device studio poller is being built for the node details widget. The plan is to add a field for serial numbers.
How would this be accomplished?
- A. Default widgets are being used, fields cannot be added to the device studio
- B. Create a serial number universal device poller (UDP) and link to the node details widget.
- C. Change one data source field to serial number and supply the OID for the data source.
- D. Add the object ID (OID) to an existing data source and edit the field name in the widget.
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To display the serial number in the node details widget using Device Studio, you must add a new data source field, name it "Serial Number," and provide the correct OID that polls the serial number from the device. This field then appears in the node details widget for the custom poller. Editing an existing field's name is not best practice, and UDPs cannot be linked directly to Device Studio widgets.
Reference:
Device Studio Admin Guide, "Adding Serial Number Field to Node Details Widget,"
"Create a data source with the OID for serial number and label the field accordingly in Device Studio."
NEW QUESTION # 85
Which tool in the web console will verify the object ID (OID) being used is a match for the node being created for a custom poller?
- A. firmware repository
