SolarWinds Hybrid-Cloud-Observability-Network-Monitoring - Hybrid Cloud Observability Network Monitoring Exam

Comprehensive and Detailed Explanation From Exact Extract:

The SolarWinds MIB database is used for SNMP-based monitoring and performs these critical functions:

A. It defines which OIDs are recognized and what metrics can be polled via Universal Device Pollers or other custom monitors.

C. It maps OIDs (numeric identifiers) to their human-readable textual names for reporting and alerting.

Options B and D are not accurate; the database does not enable automatic polling nor does it update device OIDs during polling.

Comprehensive and Detailed Explanation From Exact Extract:

SolarWinds' log processing policies for svslog (syslog) and traps (SNMP traps) are processed independently and concurrently. This is because syslog and SNMP trap processing are separate services with their own processing pipelines, unlike the global pre and post policies which affect overall log routing or rule order.

Device Studio is specifically designed to build custom pollers for missing or vendor-specific metrics that are not natively included in node details. It is best used to enrich the node details with custom OID-based metrics from devices.

From the documentation:

“Use Device Studio to build pollers for new metrics not present in the default node details, particularly for custom or third-party equipment.”

The “Device View” feature allows users to view the physical layout of device interfaces on graphical stencils, providing an intuitive graphical representation of port locations and status.

Exact Extract from Official Guide:

“Device View displays the physical layout of device interfaces using graphical stencils for supported devices.”

Device Studio supports the following data sources:

Calculated result from transformation of polled values: You can apply calculations (such as average, sum, transformation) to the raw polled data.

Polled value by a device on an object ID: Device Studio can directly poll an OID from a device and use its value for monitoring.

Night/day standard deviation and predicted/baseline values are not direct data sources in Device Studio.

When you create a flow alert in SolarWinds, the object of the alert (such as a specific interface, node, or application) is chosen from the “Create a Flow Alert” panel. Flow alerts are not based on custom SQL queries, require the NetFlow service to be running, and always have associated trigger actions.

When collecting Windows event logs without installing an agent, SolarWinds recommends converting those events to SNMP traps or syslog messages using the SolarWinds Event Log Forwarder for Windows. This allows the platform to ingest and recognize Windows events through standard logging protocols.

"The SolarWinds Event Log Forwarder for Windows enables you to forward Windows event logs as SNMP traps or syslog messages, allowing agentless collection and integration into your SolarWinds platform."

Option C, converting events to traps, is the correct method supported for agentless environments.

With Network Insight features (including for Palo Alto and F5 BIG-IP devices) installed alongside Network Configuration Manager and Performance Monitoring, you can monitor:

High availability details: Provides information on device redundancy, failover status, and clustering.

Policy details: Enables insight into firewall, security, and NAT policies for managed devices.

Access lists and VPNs may be monitored in other modules, but the primary, advanced insight is for high availability and policy configurations.

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.
