Users report that NPM performance is slow when managing devices through the Orion Web Console.
You verify the SNMP trapping is responsible for the poor performance. How do you resolve this
issue?
B
Explanation:
SNMP traps are unsolicited messages sent by network devices to report events or issues. If NPM
receives too many traps from devices that are not managed by NPM, or traps that are not relevant
for monitoring, the performance of the Orion Web Console can be affected. To resolve this issue, you
can point the devices to a trap manager, such as
Kiwi Syslog Server
, and configure it to filter out
unwanted traps before forwarding the remaining ones to the Orion Platform. This way, NPM will only
process the traps that are important for monitoring and alerting, and reduce the load on the
database and web server. Reference:

,
Filter traps in Kiwi Syslog Server

How can you ensure the trigger actions you set on an alert will work?
C
Explanation:
When you create or edit an alert, you can test the trigger and reset actions by clicking Simulate next
to the action you want to test. This will execute the action regardless of the trigger condition. You can
also select an object to resolve any variables you have used in your action. For example, if your action
is to send an email with the node name and status, you can select a node to see how the email will
look like. This way, you can ensure the trigger actions you set on an alert will work as
expected. Reference:

The Universal Device Poller retrieves management data in which format?
A
Explanation:
The Universal Device Poller (UnDP) is a feature of SolarWinds NPM that allows you to create custom
monitors for almost any statistic provided by SNMP based on its Management Information Base
(MIB) and object identifier (OID). An OID is a unique identifier for a variable that can be polled or set
via SNMP. The UnDP retrieves management data in the OID format from the devices that support
SNMP. The other formats (WMI, XML, ANSI 1) are not used by the UnDP. Reference:

You’re troubleshooting a complex network issue and need to build a comparison of several metrics
across multiple devices and SolarWinds products to identify the problem. What feature can you use?
A
Explanation:
PerfStack is a feature of the Orion Platform that allows you to compare and correlate performance
data from multiple SolarWinds products and entities in a single view1
.
You can drag and drop metrics
from different sources, such as NPM, SAM, NCM, NTA, and more, and create custom dashboards that
help you troubleshoot complex network issues2
.
PerfStack can also show historical data and
baselines for comparison3. Reference: 1: Network Performance Monitor Administrator Guide - Use
PerfStack to troubleshoot issues 2: Network Performance Monitor Getting Started Guide -

You can import device-specific MIBs into the SolarWinds MIB Database, but you cannot import UnDP
pollers based on OIDs from device-specific MIBs.
B
Explanation:
You can import device-specific MIBs into the SolarWinds MIB Database, and you can also import
UnDP pollers based on OIDs from device-specific MIBs. UnDP stands for Universal Device Poller,
which is a tool that allows you to monitor custom statistics based on OIDs with NPM. You can create
UnDP pollers by selecting OIDs from the MIB Browser, or by importing them from a file that contains
OIDs and poller names. You can then assign UnDP pollers to devices monitored by NPM and view the
results on the web console. Reference:

You have two groups of users – one in Sydney and one in Perth. How do you limit the users within the
Orion Platform so they only have access to the devices in their location?
A
Explanation:
According to the SolarWinds NPM Administrator Guide, you can use Orion groups to organize your
network objects based on any criteria, such as location, device type, department, etc. You can then
apply account limitations based on Orion groups to restrict user access to only the network objects
that belong to a specific group. For example, you can create two Orion groups, one for Sydney and
one for Perth, and assign the devices in each location to the corresponding group. Then, you can use
the single group Account limitation to limit the users in Sydney to only view the Sydney group, and
the users in Perth to only view the Perth group. Reference:

You need to add a new subnet of 500 devices for monitoring. What is the first step to incorporate
these devices into NPM?
B
Explanation:
To add a new subnet of 500 devices for monitoring, the first step is to perform a network discovery
using the Network Sonar Wizard in NPM. This wizard allows you to scan your network by IP address
range, subnet, or seed device and automatically discover and add nodes and interfaces to NPM for
monitoring. You can also specify credentials, polling settings, and custom properties for the
discovered devices. Performing a network discovery can help you quickly and efficiently incorporate
new devices into NPM without manually adding them one by one. Reference:

In which scenario is an agent the best solution?
B
Explanation:
An agent is a software component that you can install on a node to collect and send data to the Orion
server. Agents are useful when you need to monitor nodes that are behind firewalls, in the cloud, or
have overlapping IP addresses. Agents can also provide more detailed information about the node’s
performance and status than SNMP or WMI. Agents can use either agent-initiated or server-initiated
communication, depending on your network configuration and security
requirements. Reference:
NPM Administrator Guide
, page 67;

How can you quickly generate a report in NPM to show the top 50 interfaces by percent utilization?
C
Explanation:
NPM provides several default reports that can be used as templates for creating custom reports. One
of them is the Top 100 Interfaces by Percent Utilization report, which shows the average and peak
utilization of the most used interfaces in the network. To create a report that shows only the top 50
interfaces, you can copy this report and edit it to change the number of rows displayed. You can also
modify other parameters such as the time period, the grouping, the sorting, and the filtering
criteria.
To copy and edit a default report, follow these steps1
:
Click Reports > All Reports > Manage Reports.
Find the Top 100 Interfaces by Percent Utilization report and click Duplicate & Edit.
On the Layout Builder panel, click Edit Table.
On the Edit Resource panel, change the Maximum Number of Rows to 50.
Optionally, change other settings such as the Time Period, the Group By, the Sort By, and the Filter
Results.
Click Submit.
Optionally, change the Report Name, the Report Description, and the Report Category.
Click Next and then Save.
You can now run or schedule the report to show the top 50 interfaces by percent
utilization. Reference: 1

Half of your objects in a nested map are down, but the top level map is up. What is the cause?
C
Explanation:
Map status thresholds determine how the status of a map is calculated based on the status of its
child objects. If you set the map status threshold to above 50%, it means that the map will be up if
more than half of its child objects are up, regardless of the severity of the down objects. This can
cause a situation where half of your objects in a nested map are down, but the top level map is up,
because the top level map only considers the status of the nested maps, not the individual objects
within them. To avoid this, you can lower the map status threshold to a value that reflects the desired
level of availability for your network, or use custom map status thresholds to specify different values
for different maps. Reference:
Set map status thresholds in NPM
