SolarWinds Hybrid Cloud Observability Network Monitoring Exam Hybrid-Cloud-Observability-Network-Monitoring Exam Dumps: Updated Questions & Answers (October 2025)

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.”

To monitor an application on a server with SolarWinds, you must first find the application in the list of available (supported or discovered) applications and enable monitoring for it. The platform also provides a “monitor recommended applications” button to automatically suggest and enable monitoring for best-practice applications on a given server.

From the documentation:

“To monitor an application, select it from the list of available applications and enable it for the target server. The ‘Monitor Recommended Applications’ option helps you quickly enable commonly used application monitors.”

Grouping IP addresses or configuring specific source/destination pairs is not required for standard application monitoring.

The Brocade G620 switch is not supported by SolarWinds for hardware health statistics collection, regardless of the SNMP version or polling method used. SolarWinds documentation lists the specific switch models and vendors that are compatible with hardware health monitoring, and Brocade switches (including the G620) are not among the supported models for this feature.

The documentation states:

“Hardware health monitoring in SolarWinds is available for a set of supported vendors and models. Brocade G620 is not included in the list of devices that provide hardware health statistics. As a result, these statistics will not appear on the node details summary page, even if SNMP polling is enabled and working for other metrics.”

A. MIB files define the available SNMP objects and metrics that can be polled from a device.

C. MIB files provide human-readable names and descriptions for OIDs, allowing SolarWinds to display metrics in a clear, user-friendly format instead of raw OID numbers.

Automatic device discovery is handled by network scanning, not by MIB files, and OIDs are created by device vendors, not by SolarWinds.

Comprehensive and Detailed Explanation From Exact Extract:

If a device studio poller is configured with a static textual value (rather than a dynamic OID), any change in the actual value on the node will not be detected automatically; the poller’s configuration must be manually updated to reflect the new value. OID-based pollers update automatically as values change on the device.

When monitoring F5 BIG-IP load balancers, SolarWinds Network Insight requires both SNMP for device status and iControl (a proprietary F5 API) for advanced configuration and health monitoring. The SolarWinds guide states:

"After adding an F5 load balancer with SNMP, configure the iControl connection to access additional F5-specific health and configuration metrics."

Device Studio supports advanced custom polling, allowing you to build pollers for technologies such as multi-CPU/memory, node details (e.g., chassis, serial number), and single CPU/memory. While interface traffic polling is best accomplished through standard interface resources, Device Studio is designed for more advanced or complex device metrics that are not available via built-in polling.

Comprehensive and Detailed Explanation From Exact Extract:

Unknown flow traffic often occurs when SolarWinds receives flow data from sources not defined in its database, or when flow-enabled devices are not sending data to the expected port.

Add the devices and interfaces to SolarWinds' database: Ensures flow data is properly associated with monitored objects, resolving the "unknown" status.

Ensure flow-enabled devices send data to the appropriate port: If data is sent to the wrong port, SolarWinds cannot process it correctly, leading to unknown events.

SolarWinds documentation notes:

"Unknown flow traffic typically indicates a mismatch between flow sources and known device/interface configurations, or incorrect UDP port configuration. Registering devices/interfaces and verifying port assignments resolves most unknown flow issues."

The correct process for creating a poller in Device Studio is:

Select the technology

Specify the data source

Assign the poller to a node

Save the poller

Disabling NetFlow/CBQoS stops flow data collection, resulting in gaps in graphs during the disabled period (A). However, historical data collected prior to disabling is retained in the database (C), so you can still view past flow information.
