NEW QUESTION # 100
Which three of the following switch port report errors can cause a duplex mismatch? (Choose three.)
- A. are collision
- B. 100 MB full
- C. CRC
- D. > 0.5% receive
Answer: A,C,D
Explanation:
Duplex mismatches often result in specific types of switch port errors. According to SolarWinds documentation, the most common indicators of a duplex mismatch include CRC errors (B), high receive error percentages (C), and collisions (D). These errors occur because one end of the link operates in full-duplex mode (no collisions expected), while the other operates in half-duplex (collisions possible), resulting in frame errors, dropped packets, and high CRC counts. The option " 100 MB full " refers to a speed/duplex setting, not an error.
Reference:
Network Performance Monitor Administrator Guide, "Diagnosing Duplex Mismatches - Symptoms and Errors,"
"CRC errors, excessive receive errors, and collisions are strong indicators of a duplex mismatch on switch ports."
NEW QUESTION # 101
Which tool presents live flow traffic data sourced from/to a main polling engine server, providing basic insight into traffic on the main polling engine?
- A. collector service
- B. local NetFlow source
- C. CBQoS/flow sources
- D. flow navigator
Answer: B
Explanation:
The local NetFlow source provides live (real-time) flow traffic data that is sourced to and from the main polling engine server. This feature is primarily for monitoring the main polling engine's traffic and quickly identifying top talkers and general flow activity on that server.
Reference:
" The Local NetFlow Source shows live NetFlow traffic sent to and from the main polling engine, giving insight into the traffic patterns for the main server. "

Answer: A,C,D
NEW QUESTION # 103
A device studio poller is being built for node detail information. For the values supported, it has been decided to enter textual values instead of object IDs (OIDs). Which statement is true?
- A. If the textual value changes, it will update automatically.
- B. If the textual value changes on the node, the poller must be manually updated.
- C. If the textual value is misspelled, it will not poll correctly.
- D. Only textual values can be used for host names, all other values must be OIDs.
Answer: B
Explanation:
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.
Reference:
Device Studio Admin Guide, "Using Static Text vs. OID Polling,"
"Static text fields must be manually updated if the real value changes, whereas OID values are polled dynamically."
NEW QUESTION # 104
An unknown traffic event is noted in the web console. What is the likely cause?
- A. receiving flows from a device not monitored by the network
- B. missing a byte group from flow field configurations
- C. incorrectly configured source or destination port in the flows
- D. a firewall is blocking the traffic flow configurations
Answer: A
NEW QUESTION # 105
Which custom filter allows a user to view specific statistics about an entire network and its devices without having to navigate through the web console by single-device views?
- A. NBAR2
- B. flow alert
- C. flow navigator
- D. top 10 applications
Answer: C
Explanation:
The Flow Navigator in SolarWinds NetFlow Traffic Analyzer (NTA) is a powerful custom filter and analysis tool. It enables users to apply multiple filters to NetFlow data, allowing the visualization of specific statistics about the entire network or selected subsets, such as all traffic from a certain IP range or application. This approach eliminates the need to manually click through device-by-device views, instead providing comprehensive traffic analysis across the whole monitored environment through a single, customizable interface.
Reference:
" Use the Flow Navigator to apply multiple filters for viewing NetFlow data, enabling users to see traffic patterns for the entire network or specific subnets, applications, or endpoints without needing to open individual device pages. "
- (Network Performance Monitor Administrator Guide, Section: NetFlow Traffic Analysis)
NEW QUESTION # 106
In device studio, the test node being built for a new custom poller is returning four usage values for the CPU (one for each CPU core). If the goal is to have one value for the entire CPU, how can that be accomplished?
- A. device studio would not be the correct tool to use in this situation
- B. values can be combined after the poller is created in poller settings
- C. create a new calculated value to average the four individual values
- D. there is not an object ID (OJD) for CPU usage, nothing can be done
Answer: C
Explanation:
Device Studio allows you to define calculated values based on multiple polled results. To aggregate per-core CPU usage into a single metric, you can create a calculated value (such as the average) using the outputs from all cores.
From the documentation:
"Device Studio enables you to define calculated values (such as sum or average) when multiple SNMP values are returned, allowing you to represent a total or average CPU usage." References:
NPM Administrator Guide: Device Studio Calculated Values
NEW QUESTION # 107
Which additional polling method is needed after adding Cisco ASA and Cisco Nexus for SNMP monitoring?
- A. WMI
- B. API
- C. Control
- D. ICLI
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
When adding Cisco ASA and Cisco Nexus devices for monitoring, SolarWinds recommends enabling SNMP monitoring. However, to fully monitor these devices-especially for advanced features, hardware health, and interface statistics-the use of ICLI (Intermediary Command Line Interface) polling is required in addition to SNMP. ICLI enables the SolarWinds platform to retrieve deeper metrics, such as VLANs, VRFs, and other device-specific statistics, that are not exposed via SNMP alone. This requirement is specified in the official SolarWinds NPM Administrator Guide, which details that ICLI must be enabled for Nexus and ASA devices for comprehensive monitoring.
Reference:
Network Performance Monitor Administrator Guide, "Monitoring Cisco Nexus and ASA Devices - Polling Methods Required"
NEW QUESTION # 108
It is noted that the hardware health monitoring for a Cisco switch is generating false positives. It is verified that the alerted hardware issues are not occurring. What is causing the issue?
- A. Hardware sensors were incorrectly assigned to another switch.
- B. Restart SNMP on the device to refresh the hardware statistics.
- C. Modify the widget thresholds to filter out the false positives.
- D. MIB on the device is notthe preferred MIB that is beingpolled.
Answer: D
NEW QUESTION # 109
If a NetFlow collector service is showing a "down" status, which two of the following steps are possible troubleshooting options? (Choose two.)
- A. Delete and re-add NetFlow collector service.
- B. Start or restart SolarWinds' NetFlow service from Orion service manager.
- C. Confirm the database connection is up and server has free resources.
- D. Start or restart SolarWinds' collector service.
Answer: B,C
Explanation:
When the NetFlow collector service is showing a " down " status, the SolarWinds documentation recommends the following troubleshooting steps:
* Confirm the database connection is up and server has free resources.
* Explanation: The NetFlow collector service relies on connectivity to the SolarWinds database. If the database connection is lost or the server is out of resources (such as CPU or RAM), the service may go down or fail to start. Ensuring that the database is reachable and that the server has enough resources is a primary troubleshooting step.
* Start or restart SolarWinds' NetFlow service from Orion Service Manager.
* Explanation: The official troubleshooting guidance instructs administrators to use the Orion Service Manager to start or restart the NetFlow service. This is a direct method to recover the NetFlow collector from a " down " state and is one of the first actions recommended by SolarWinds support.
Options B and C are not recommended in the official documentation:
* Deleting and re-adding the NetFlow collector service is not a documented troubleshooting step and may cause loss of configuration.
* Starting or restarting the generic " collector service " is not specific to NetFlow; the correct service is the NetFlow service.
Exact Extract from Official Guide:
" If NetFlow collector service status is down:
* Ensure the SolarWinds database is online and the server is not experiencing resource issues.
* Use the Orion Service Manager to start or restart the NetFlow service.
* If the issue persists, review the NetFlow logs for errors and consult the SolarWinds Success Center for advanced troubleshooting. " - (Network Performance Monitor Administrator Guide, Troubleshooting NetFlow and Service Issues) References:

The documentation specifies:
" SNMP v3 provides secure authentication and encryption options, including MD5, SHA1, SHA256, and SHA512. Versions 1 and 2c only support community string authentication. " References:
NPM Administrator Guide: SNMP Security and Supported Authentication Methods
NEW QUESTION # 112
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. router is configured as a parent in a node dependency
- B. ICMP is blocked between the device and the polling engine
- C. agent connection status with the polling engine is "down'
- D. SNMP is blocked between the device and the polling engine
Answer: B,D
NEW QUESTION # 113
Which method is used to add new UPS battery status statistics onto an existing node that does not have the default value polled?
- A. create new custom device poller
- B. update SolarWinds ' MIB database
- C. define custom statistic with universal device poller (UnDP)
- D. custom statistics cannot be added to an existing node
Answer: C
Explanation:
The Universal Device Poller (UnDP) allows administrators to define custom SNMP OIDs for statistics (like UPS battery status) that are not natively polled. You can assign a new UnDP to an existing node to monitor additional values such as UPS battery status, provided the device supports the necessary OID.
Reference:
" Use the Universal Device Poller to assign additional custom statistics, such as UPS battery status, to any node that supports the relevant SNMP OID. "
- (Network Performance Monitor Administrator Guide, Universal Device Poller section)
NEW QUESTION # 114
When a parent object goes down or becomes unresponsive, all interfaces on the switch will also be unresponsive. Though they may be working, "unreachable" status is used because the parent node reports as
"down" and a status cannot be determined. Any alerts where the trigger condition includes node status equal to
"down" are not triggered.
In which section of SolarWinds' platform can an administrator configure the status of child objects as
"unreachable" instead of "down" or "unknown"?
- A. manage dependencies
- B. polling settings
- C. core thresholds
- D. node status participation
Answer: A
NEW QUESTION # 115
A poller is to be built that will add two values together to show a single value in the web console using the universal device poller (UDP) tool. How would this be accomplished?
- A. add both object IDs (OIDs) to the poller and combine values in a single value for the web console
- B. UDP tool does not support more than one OID per poller, another OID is needed
- C. UDP tool does not support more than one OID per poller, another tool is needed
- D. build a poller for each OID then use transform results to combine values from the two pollers
Answer: D
NEW QUESTION # 116
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. MIB browser
- B. CLI settings
- C. component library
- D. firmware repository
Answer: A
Explanation:
The MIB browser tool in the SolarWinds web console is designed to browse, query, and verify OIDs on monitored nodes. It allows you to test if an OID returns valid data for a specific device before assigning it in a custom poller. This ensures compatibility and accuracy of your custom monitoring setup.
Reference:
Universal Device Poller Admin Guide, "Using the MIB Browser,"
" The MIB browser verifies if an OID is valid and supported on the node. "
NEW QUESTION # 117
Which additional polling method is needed after adding an F5 load balancing node for SNMP monitoring?
- A. iControl
- B. API
- C. CLI
- D. WM1
Answer: A
NEW QUESTION # 118
Upon examining bandwidth utilization, it is confirmed that the total utilization and flow numbers do not match. What is the likely cause?
- A. flows do not contain all traffic in bandwidth numbers
- B. receiving both IPv4 and IPv6 flows and not all are counted in total bandwidth
- C. a firewall is blocking the data flow configuration
- D. SNMP bandwidth numbers for the interface need to be adjusted in the console
Answer: A
Explanation:
The most common cause of mismatch between bandwidth (SNMP) numbers and flow (NetFlow, sFlow, etc.) numbers is that not all network traffic is included in the flow export. SNMP bandwidth counters include all traffic traversing the interface, but NetFlow or other flow records may only represent sampled or filtered subsets, or may miss certain traffic due to export or device configuration limitations. This is a well- documented and expected difference in the SolarWinds platform.
