NEW QUESTION # 53
Flow traffic in the web console is reviewed and it is noted that there is unclassified traffic. Which two of the following reasons are possible causes for the issue? (Choose two.)
- A. The flows from the device are generated by an application using a different port than what is mapped in HCO.
- B. The flows from the device are set to ingress instead of egress.
- C. The flows from the device are generated by an application not mapped in hybrid cloud
- D. The flows from the device are not supported by HCO.
Answer: A,C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
SolarWinds identifies and classifies flow traffic based on application and port mapping in the platform.
"Unclassified traffic in flow charts often occurs when an application is not mapped in the system, or when the application uses a port that is not defined in the SolarWinds Hybrid Cloud Observability (HCO) application mapping database. Flows from unsupported devices or flow direction do not cause unclassified application traffic-rather, they will not be collected or will be marked as unknown flows." Thus, unclassified traffic can result from new or custom applications or changes in port usage that are not reflected in the configuration.

NEW QUESTION # 57

- A. verily the credentials for the new node are valid
- B. assign the new node to the same polling engine

Answer: D
NEW QUESTION # 58
A network discovery profile for a network area completes with most devices discovered, except for a few SNMP-enabled network devices. These undiscovered devices are verified to be operational and respond to SNMP queries.
What could be the cause?
- A. no SNMP pollers match the device
- B. SNMP community strings in profile are invalid
- C. device MIB is not in SolarWinds' MIB database
- D. discovery timeout value is set too low
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
If devices respond to SNMP queries individually but aren't discovered during network scans, the most likely cause is the discovery timeout value being set too low. This can result in slower devices timing out before responding to discovery requests, even though they are operational and SNMP-enabled.
The documentation explains:
"If devices are not discovered but respond to SNMP queries, increase the discovery timeout and retry. Short timeouts can cause missed responses from devices that take longer to reply during scanning." References:
Network Performance Monitor Administrator Guide, Section: "Discovery Troubleshooting" SolarWinds Success Center: "Device Not Found During Discovery"
NEW QUESTION # 59
Which three of the following are effects of enabling the "resolve IPv4 and IPv6 addresses to DNS hostname" option and disabling the "resolve and store IPv4 hostname immediately when a flow record is received" option? (Choose three.)
- A. DNS names will not be displayed on top domain resources/reports
- B. number of reads/writes on SQL server linked to name resolution is reduced
- C. amount of database memory used to store DNS information is reduced
- D. amount of database space used to store received flows is reduced
Answer: B,C,D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Enabling DNS resolution but not storing hostnames immediately results in:
Reduced database memory/storage used for DNS info, as hostnames aren't stored with each flow record.
Less database space used for flows, since flow records will reference IPs rather than resolved DNS names.
Reduced SQL server reads/writes since the platform does not immediately resolve and store hostnames with every received flow, decreasing load.
DNS names will still appear in reports where resolved dynamically, so option C is incorrect.
Reference:
NTA Administrator Guide, "Flow storage and DNS resolution options,"
"Disabling immediate hostname resolution and storage reduces database use and SQL operations."
NEW QUESTION # 60
If an SNMP community string is changed on a device, which two of the following steps are required to re-establish successful polling on the node? (Choose two.)
- A. Restart the SNMP service on the source device.
- B. Update the community string in node properties.
- C. Edit the node properties and save the changes.
- D. Delete and add the node back into the platform.
Answer: B,C
NEW QUESTION # 61
Through which means does NetFlow traffic analysis (NTA) process flow data?
- A. configuration
- B. collector
- C. agent
- D. polling method
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
SolarWinds NTA processes flow data via a dedicated collector component. Devices are configured to export flow records to the NTA collector, which ingests, stores, and analyzes the data.
"NetFlow Traffic Analyzer receives flow data from network devices using the NetFlow Collector service, which processes and stores traffic information for analysis." No agent is required on target devices, and the collector is the key processing method.

- C. night and day standard deviation of calculated value
- D. predicted value from OID baseline
Answer: A,B
NEW QUESTION # 63
A "no data" message is displayed in NetFlow charts. How can this be resolved?

NEW QUESTION # 66
Upon logging into the web console to check node statuses, it is noted that several nodes display a "down" status when they are up and running. Which two of the following situations are the likely causes of this issue?
(Choose two.)
- A. ICMP blocked from polling engine to target node
- B. polling interval set to value other than default
- C. nodes usingincorrect SNMP credentials
- D. nodestatus must be set to au management
Answer: A,C
NEW QUESTION # 67
The web console is showing the status of a network router as "down", however the node is up and running.
Which two of the following causes could be creating the issue? (Choose two.)
- A. agent connection status with the polling engine is "down"
- B. ICMP is blocked between the device and the polling engine
- C. router is configured as a parent in a node dependency
- D. SNMP is blocked between the device and the polling engine
Answer: B,D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
If the web console shows a router as "down" but it is actually operational:
ICMP is blocked: If the polling engine cannot ping the device, it will be reported as down.
SNMP is blocked: If SNMP polling fails (for devices polled via SNMP), detailed data and status cannot be retrieved, resulting in a down state.
Agent connection issues may apply for agent-based monitoring but are not typical for network routers. Node dependency configuration could affect child node status display but would not cause the parent node to show
"down".
