Question 1

How many agents does NPM require for Quality of Experience, NetPath, and system monitoring on the same Windows server?



Answer : B

NPM requires only one agent for Quality of Experience, NetPath, and system monitoring on the same Windows server.The agent is a software component that collects data from the server and sends it to the Orion server1.The agent can perform multiple tasks, such as packet analysis, network path analysis, and system health monitoring, depending on the configuration and the license2.You can install the agent on the server either manually or remotely from the Orion Web Console3.Reference:1: Network Performance Monitor Administrator Guide - Agents2: Network Performance Monitor Getting Started Guide - Monitor with agents3: Network Performance Monitor Installation Guide - Install agents


Question 2

How many days of data must your database contain in order to see Capacity Forecast Charts in NPM?



Answer : C

Capacity Forecast Charts in NPM show the usage trends and forecasts for nodes, interfaces, and volumes based on historical data.By default,7 days of dataare required to generate these charts1.You can change this setting globally or individually for each object2.Capacity Forecast Charts are available for the following metrics: CPU utilization, memory usage, space usage, receive utilization, and transmit utilization3.Reference:1: Monitor capacity usage trends on the network and forecast capacity issues in NPM - Capacity forecasting is available for nodes, interfaces, and volumes that meet the following requirements2: Change capacity forecasting settings globally in NPM - Change the number of days of historical data required for capacity forecasting3: Monitor capacity usage trends on the network and forecast capacity issues in NPM - Capacity forecasting is available for the following metrics of monitored nodes, interfaces, and volumes monitored


Question 3

Status, Average Response Time, and Packet Loss are the only node details data you can view for your switch A device. The node details of your identical switch B device show Status, Average Response Time, and Packet Loss and other statistics. How can you monitor the other statistics on switch A and not lose any historical data?



Answer : B

According to the SolarWinds NPM Administrator Guide, you can edit the node properties of any device and change the polling method to suit your needs. The polling method determines what data is collected and displayed for the node. The ''Most Devices: SNMP and ICMP'' polling method collects and displays the most comprehensive data, including CPU load, memory utilization, interface statistics, and more. The ''Status Only: ICMP'' polling method only collects and displays the node status, average response time, and packet loss. If you want to monitor the other statistics on switch A, you should change the polling method to ''Most Devices: SNMP and ICMP''. This will not affect the historical data that has already been collected for switch A, as it will be stored in the database. However, deleting switch A and adding it again, or adding switch A again without deleting it first, will result in losing the historical data or creating duplicate nodes.Reference:SolarWinds NPM Administrator Guide, page 78-79;Polling methods used by Orion


Question 4

What is the most time-efficient way to create a report in NPM that shows the top 50 interfaces by percent utilization?



Answer : B

NPM provides a default report calledTop 25 Interfaces by Percent Utilizationthat shows the interfaces with the highest average utilization over the selected time period1.This report can be easily edited to change the number of interfaces displayed, the time period, the sorting order, the layout, and the filters2.To create a report that shows the top 50 interfaces by percent utilization, you can simply edit this report and change theLimitoption from 25 to 503.This is the most time-efficient way to create the report, as it does not require creating a new report from scratch, writing a SQL query, or running the report multiple times for different timeframes.Reference:1: Network Performance Monitor Administrator Guide - Top 25 Interfaces by Percent Utilization2: Network Performance Monitor Administrator Guide - Edit a report3: Network Performance Monitor Getting Started Guide - Customize a report


Question 5

You receive an alert that one of your routers is experiencing critical level CPU utilization. The router details in the web console show as critical utilization, but you do not consider the utilization on that router to be at a critical level.

What change can you make in NPM to reflect a CPU utilization level you consider to be critical for the device?



Answer : C

By default, NPM uses the global critical CPU threshold for node statuses, which is 90%. However, you can override this threshold for individual nodes by editing their properties and specifying a custom value for the critical CPU threshold. This way, you can adjust the threshold according to the specific characteristics and performance of each node. Changing the critical CPU threshold on the node will affect how the node status is calculated and displayed in the web console, as well as how the alerts are triggered based on the CPU utilization.Reference:Thresholds in the SolarWinds Platform;CPU Critical Threshold - Forum - Network Performance Monitor (NPM) - THWACK


Question 6

You configure an alert to send you an email when you have a high CPU load on your devices. Your NPM web console shows several devices have high CPU utilization, but you have not received any emails. What could be the issue?



Answer : C

One possible reason why you have not received any emails for the high CPU load alert is that the alerts are muted on the devices. Muting alerts means that the alert conditions are still evaluated, but the alert actions are not executed. This can be useful when you want to temporarily suppress notifications for planned maintenance or testing. You can mute alerts for individual nodes, groups, or applications, or for all alerts in the Orion Platform. To check if the alerts are muted on the devices, you can go to the Manage Nodes page and look for the Muted column. You can also use the Mute Alerts widget on the Orion homepage to see the status of alert muting. To unmute alerts, you can either use the same widget or the Unmute Alerts option in the node, group, or application details page.Reference:Mute alerts,Manage nodes,Mute Alerts widget


Question 7

You inherit an environment with NPM and begin to receive High Traffic Utilization alerts from interfaces. When you view the alert, the issue is resolved. How do you modify NPM to receive fewer false alerts?



Answer : A

High Traffic Utilization alerts are triggered when the interface's received or transmitted percent utilization exceeds a specified threshold. However, this may not reflect the actual network congestion, as traffic spikes can occur momentarily and then subside. To avoid false alerts, you can configure the alert to trigger only when the traffic utilization remains high for a sustained period, such as 5 minutes or more. This way, you can filter out the transient traffic peaks and focus on the persistent issues that affect the network performance.Reference:
