NEW QUESTION # 48
Which two of the following best practices are used when creating a universal device poller (UDP)? (Choose two.)

• A. Perform SNMPwalk to determine if OID exists.
• B. Call SolarWinds support for object ID (OID) options.
• C. Consult vendor documentation for OID.
• D. Run WBemtest to test communication to OID.

Answer: A,C

Explanation:
The best practices for creating a Universal Device Poller (UDP) in SolarWinds are:
Consult vendor documentation for OID: Always check the device/vendor documentation for the correct OID to monitor the desired metric.
Perform SNMPwalk to determine if OID exists: Use SNMPwalk to verify the OID's existence and see if it is supported and returns the correct values from the device.
Calling SolarWinds support is not a standard step for obtaining OIDs, and WBemtest is a Windows tool for WMI, not SNMP/OID polling.
Exact Extract from Official Guide:
"Consult device vendor documentation for correct OIDs and perform SNMPwalk to ensure the OID exists and is supported by the device before creating a UDP."

NEW QUESTION # 51
How does data collection with a flow collector differ from data collection with a polling engine?

• A. flow data is processed by flow collector or polling engine
• B. flow data is collected by flow collector and processed by polling engine
• C. flow collector is a type of polling engine for flow data
• D. source devices must be configured to send their data to a flow collector

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Flow collectors differ from polling engines because they passively receive and process flow records sent by network devices, while polling engines actively poll devices for data (like SNMP). Devices must be explicitly configured to export their NetFlow, sFlow, or J-Flow records to the IP address and port of the flow collector, rather than being queried by the SolarWinds server.
The documentation states:
"To monitor flow data, devices must be configured to send their flow records to the collector. Unlike traditional polling, the collector does not initiate contact; it listens for incoming flow exports from network devices." References:
Network Performance Monitor Administrator Guide, Section: "Flow Collector Operation" SolarWinds NTA Documentation

NEW QUESTION # 52

• C. stop SolarWinds' NetFlow service and separate listed ports with a comma in the NetFlow collector services widget
• D. replace existing port with new port in the NetFlow collector services widget

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To add additional NetFlow collector ports, you must stop the NetFlow service and then specify multiple ports separated by commas in the NetFlow collector services widget.
From the documentation:
"To configure multiple collector ports, stop the NetFlow service, edit the collector ports in the widget by separating them with commas, and then restart the service." References:
NTA Administrator Guide: Configuring NetFlow Collector Ports

NEW QUESTION # 55
What is the unit of data used for alerting on flows?

• A. mbps
• B. bPs
• C. ms
• D. gps

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The standard unit for flow-based alerts in SolarWinds (e.g., NetFlow Traffic Analyzer) is megabits per second (mbps). Alerts regarding traffic rates, bandwidth utilization, and similar flow metrics are configured and displayed in mbps for consistency with network monitoring best practices.
Reference:
"Traffic flow alert thresholds are set and displayed in megabits per second (mbps) within the SolarWinds web console and NTA."
- (Network Performance Monitor Administrator Guide, Alerting on Flow Traffic section)

NEW QUESTION # 56
In which two of the following cases does duplicate flow data occur? (Choose two.)

• A. IP flow ingress on some interfaces and egress on others
• B. both IP flow ingress and egress applied for all interfaces
• C. IP flow ingress applied on all interfaces, no egress usage
• D. both IP flow ingress and egress applied on one interface

Answer: B,D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Duplicate flow data typically results when both ingress and egress flow monitoring are applied simultaneously on interfaces. If both directions are enabled either globally (all interfaces) or locally (on a single interface), the same flow is counted twice-once entering and once leaving-resulting in duplicate statistics.
Reference:
"To avoid duplicate flow data, do not enable both ingress and egress NetFlow on the same interface or across all interfaces. Doing so will cause the same packets to be exported twice and counted as duplicates in reports and charts."
- (Network Performance Monitor Administrator Guide, NetFlow configuration best practices section)
