NEW QUESTION # 43
You need to implement service level agreement (SLA) reporting for a new hosted data center service. Which SLA performance metric should you track?
- A. Memory utilization
- B. Response time
- C. Interface discards
- D. CPU utilization
Answer: B
Explanation:
Response time is the amount of time it takes for a service request to return a response. It is a critical SLA performance metric for a hosted data center service, as it directly affects the user experience and satisfaction. High response time can indicate network congestion, server overload, or other performance issues that can degrade the quality of the service. By tracking response time, you can monitor the availability and reliability of the service, identify and troubleshoot potential problems, and ensure that the service meets the SLA expectations and standards.

NEW QUESTION # 44
What can you use to retrieve a single value in SNMP? (Choose all that apply.)
- A. GET NEXT
- B. GET
- C. GET VALUE
- D. GET TABLE
Answer: A,B
Explanation:
SNMP (Simple Network Management Protocol) is a protocol that allows network managers to monitor and control network devices using a set of standardized messages and data structures. SNMP uses a client-server model, where the network manager (client) sends requests to the network device (server) and receives responses. The network device has an SNMP agent that collects and reports the data using a MIB (Management Information Base), which is a hierarchical database of variables that describe the device's status and configuration. Each variable in the MIB has a unique identifier called an OID (Object Identifier), which is a dot-separated sequence of numbers that follows a tree structure12.
To retrieve a single value in SNMP, you can use two types of requests: GET and GET NEXT. A GET request asks for the value of a specific OID, and the SNMP agent responds with the value if it exists, or an error if it does not. A GET NEXT request asks for the value of the next OID in the MIB tree, and the SNMP agent responds with the value and the OID of the next variable, or an error if there is no next variable. A GET NEXT request can be useful for discovering the OIDs and values of a device, or for iterating over a table of values34.
A GET VALUE request is not a valid SNMP request, and a GET TABLE request is not a single request, but a series of GET NEXT requests that retrieve all the values in a table .

NEW QUESTION # 45
For any node you monitor, you can use Network Discovery to automatically add child volumes or interfaces for monitoring.
- A. FALSE
- B. TRUE
Answer: A
Explanation:
For any node you monitor, you cannot use Network Discovery to automatically add child volumes or interfaces for monitoring. Network Discovery is a tool that helps you identify and add new devices to your network, but it does not automatically monitor all the components of the discovered devices. You need to manually select the volumes or interfaces you want to monitor from the list of resources on each node. You can also use the Network Sonar Results Wizard to filter and add the resources you want to monitor after running a discovery job. Reference:

NEW QUESTION # 46
You use NPM to monitor a set of physical servers. The server team decides to virtualize these servers using VMware. Which part of your virtual infrastructure will NPM no longer be able to monitor?
- A. Virtualization host hardware health
- B. Virtualization environment tree
- C. Virtualization host and VM performance metrics
- D. VM sprawl monitoring
Answer: B
Explanation:
NPM can monitor the virtualization host hardware health, VM sprawl, and virtualization host and VM performance metrics using the Virtualization Manager Integration feature1. However,NPM cannot display the virtualization environment tree, which shows the hierarchical relationship between the virtualization hosts, clusters, datastores, and VMs. This feature is only available in Virtualization Manager2, a separate product that can be integrated with NPM. References: 1: Network Performance Monitor Administrator Guide - Monitor virtual infrastructure 2: Virtualization Manager Getting Started Guide - View the virtualization environment tree

NEW QUESTION # 48
What is the average resource consumption of an agent?
- A. Less than 1% CPU, no storage because the agent is 1% in memory for faster access
- B. Agents run as a virtual process and do not require local resources
- C. Between 1-2% CPU if the bandwidth is less than 8 KB/s
- D. Less than 1% CPU, max 1 MB of memory, 1 MB storage
Answer: D
Explanation:
According to the SolarWinds Platform Agent requirements, the average resource consumption of an agent is less than 1% CPU, max 1 MB of memory, and 1 MB storage on the target computer. The agent software is designed to be lightweight and efficient, and does not impact the performance of the monitored devices. The other options are incorrect, as they either overestimate or underestimate the resource consumption of the agent, or imply that the agent does not use any local resources at all. Reference: SolarWinds Platform Agent requirements, section "SolarWinds Platform Agent resource consumption".
NEW QUESTION # 49
You run ten reports on three assorted weekly schedules and send the results to the network operations distribution list. The email address for the distribution list changed, and you must update the new email address to send the reports. How do you implement this update?
- A. Use the Action Manager to edit each action on each report schedule, and change the email address
- B. Edit each action on each report schedule, and change the email address
- C. Make a copy of each report, edit the action to change the email address
- D. Use the Schedule Manager to edit each action on each report schedule, and change the email address

NEW QUESTION # 50
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?
- A. The alerts are muted on the devices
- B. The alert threshold is set too high
- C. The hardware resources assigned to the system are too low
- D. SNMP is not configured on the devices
Answer: A
Explanation:
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. References: Mute alerts, Manage nodes, Mute Alerts widget
NEW QUESTION # 51
You deploy a new router on your network. What should you do to ensure NPM correctly interprets SNMP traps from the device?
- A. Review your firewall rules to ensure the traps are not blocked
- B. Update the MIB database
- C. Verify that NPM is using the correct SNMP community strings
- D. Contact the router vendor fora firmware update
Answer: B
Explanation:
SNMP traps are unsolicited messages sent by SNMP-enabled devices to notify the NPM server of important events or problems, such as device failures, configuration changes, or performance issues. SNMP traps contain information about the device and the event, such as the device name, IP address, timestamp, and OID (Object Identifier). An OID is a unique identifier for a specific variable in a MIB (Management Information Base), which is a hierarchical database of device information that can be accessed by SNMP. However, not all OIDs are recognized by NPM by default, as different devices may use different or custom MIBs and OIDs. Therefore, to ensure NPM correctly interprets SNMP traps from a new router on your network, you need to update the MIB database with the latest MIBs from the router vendor or from the SolarWinds website. This will allow NPM to translate the OIDs in the SNMP traps into meaningful names and values, and display them in the Trap Viewer or use them in alerts12.
To update the MIB database, follow these steps3:
Download the MIB files from the router vendor's website or from the SolarWinds MIB Database.
Copy the MIB files to the \SolarWinds\Orion\Mibs folder on the NPM server.
Click Settings > All Settings > Manage MIBs.
Click Add New MIB and browse to the MIB file that you want to add.
Click Submit.
Repeat steps 4 and 5 for each MIB file that you want to add.
Click Compile to compile the MIBs and update the MIB database.
You can now view the SNMP traps from the new router in the Trap Viewer or use them in alerts. Reference: 1: SNMP Traps Explained: How to View SNMP Traps, 2: SNMP Traps in NPM, 3: Update the SolarWinds MIB Database for the SolarWinds Platform, : SolarWinds MIB Database, : 2, : 1, : 3, : 4

NEW QUESTION # 54
Your network includes the headquarters and three remote sites. Users from remote site A complain they do not have access to the company's accounting server. Users from remote site B and C have access to the accounting server. How can you find the source of the issue?
- A. Use NetPath to see if there are problem areas between remote site A and remote sites B and C
- B. Verify that the accounting servers are up
- C. Verify that the accounting servers' CPU utilization are not abnormally high
- D. Use NetPath to see if there are problem areas between remote site A and the headquarters
Answer: D
Explanation:
NetPath is a feature of SolarWinds NPM that helps you identify network problems faster by automatically creating a map of the problem area, with a wide variety of supporting information. NetPath displays the performance details of devices inside and outside of your network. You can use NetPath to see the node-by-node network path from a probe at remote site A to the accounting server at the headquarters, and isolate the node or connection that is decreasing end-to-end performance. If the issue is external, NetPath identifies the name of the company that owns the node and displays their contact information. If the issue is internal, NetPath incorporates data from NPM, NCM, and NTA about your on-premises gear. The other options are not as effective as NetPath in finding the source of the issue, as they do not provide the same level of visibility and analysis of the network path. References:

NEW QUESTION # 56
NPM polls static properties, and calculates bandwidth consumption based on the total amount of _____ coming through the firewall.
- A. Bytes
- B. Kilobytes
- C. Megabytes
- D. Nibbles
Answer: A
Explanation:
NPM polls static properties, such as interface speed and duplex mode, from the firewall devices using SNMP. NPM also collects traffic statistics, such as bytes in and bytes out, from the firewall interfaces using SNMP or NetFlow. NPM then calculates bandwidth consumption based on the total amount of bytes coming through the firewall over a given time interval. Bandwidth consumption is expressed as a percentage of the interface speed. For example, if a firewall interface has a speed of 100 Mbps and NPM polls 10 MB of bytes in and 10 MB of bytes out in one minute, the bandwidth consumption is 20% [(10 MB + 10 MB) / 100 Mbps * 100%]1.

NEW QUESTION # 57
How many agents does NPM require for Quality of Experience, NetPath, and system monitoring on the same Windows server?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
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.

NEW QUESTION # 59
When a router monitored by NPM reboots, the interface indexes statuses change to unknown in NPM. What do you do after you remove the unknown interfaces?
- A. Manually update the interface indexes
- B. Run the Configuration Wizard to update the interface indexes
- C. Rum a list of resources on that node and add the interfaces with the updated index IDs
- D. Update the NPM internal ID numbers
Answer: C
Explanation:
When a router monitored by NPM reboots, the interface indexes may change, causing the interface statuses to become unknown in NPM. This is because NPM uses the interface indexes to identify and poll the interfaces.
To resolve this issue, you need to remove the unknown interfaces from NPM and then run a list of resources on that node to discover the interfaces with the new index IDs. You can then add the interfaces back to NPM and resume monitoring them. References:

NEW QUESTION # 60
When you configure a report, you can limit access to specific users.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
When you configure a report in the SolarWinds Platform Web Console, you can limit access to specific users by assigning a report limitation category to the report and to the user account. A report limitation category is a custom label that defines which reports a user can see. For example, you can create a "finance" category and assign it to the reports and users related to the finance department. Users with the "finance" category can only access the reports with the same category, and not the reports with other categories, such as "marketing" or "IT". You can also prevent users from accessing any reports by applying the "No Reports" limitation to their account, or allow administrators to see all reports by applying the "No Limitation" category to their account. Reference: Restrict who can access reports in the SolarWinds Platform, Define what users can access and do in the SolarWinds Platform.
NEW QUESTION # 61
You can use Device Studio to create pollers for CPU and memory?
- A. FALSE
- B. TRUE
Answer: B
Explanation:
Device Studio is a feature in the SolarWinds Platform Web Console that allows you to create custom pollers for devices or technologies that are not supported by default in NPM. You can use Device Studio to create pollers for CPU and memory, as well as other metrics, by defining the object identifiers (OIDs) and formulas that you want to poll. Device Studio currently supports SNMP and WMI polling technologies, and you can test, assign, and edit your custom pollers from the Manage Pollers page. Reference: Create pollers in Device Studio for NPM, Device Studio, Device Studio Poller.
NEW QUESTION # 62
All users can create their own Orion Maps. How do you limit a user from seeing or working with select monitored entities through the SolarWinds server?
- A. Configure Account limitations to remove access to the Orion user account
- B. Configure Alert imitations to remove access to the Orion user account
- C. Unmanage entities to remove access to the Orion user account
- D. Configure permissions on the monitored entity to remove access to the Orion user account
Answer: A
Explanation:
Account limitations are a way of restricting the access of Orion user accounts to specific network objects, such as nodes, interfaces, groups, maps, or alerts. You can use account limitations to prevent a user from seeing or working with select monitored entities through the SolarWinds server. For example, you can limit a user to see only the nodesin a certain group, or only the maps that they have created. You can apply account limitations to individual users or user groups, and you can choose from predefined limitations or create custom limitations based on custom properties. The other options are not effective ways of limiting user access to monitored entities, as they either affect the monitoring status of the entities (unmanage), the permissions of the entities themselves (configure permissions), or the alerting scope of the entities (configure alert limitations).

NEW QUESTION # 63
You add several nodes for monitoring and can see detailed information on those nodes in the Orion Web Console. However, when you look at the nodes in Orion Maps, the connections between the nodes are not showing. What is a likely reason?
- A. You did not enable Layer 2 and Layer 3 topology polling on those nodes
- B. You did not enable SNMP polling
- C. You did not add the node topology OIDs to the MIB database
- D. A firewall is blocking polling between the nodes and the Orion server
Answer: A
NEW QUESTION # 64
You want to create a custom poller for a device. When you select the OID you get an "OID not supported" error. What does this mean?
- A. This OID requires the read/write community string
- B. The SNMP agent on the device does not report on this OID
- C. Your firewall is blocking SNMP requests
- D. The SNMP string that you used is incorrect
Answer: B
Explanation:
An OID (Object Identifier) is a unique identifier for a specific variable in a MIB (Management Information Base) that can be polled or monitored by SNMP (Simple Network Management Protocol). However, not all OIDs are supported by all devices or SNMP agents, which are software components that collect and report the MIB data. If you select an OID that is not supported by the device or the SNMP agent, you will get an "OID not supported" error when you try to create a custom poller for that device in NPM (Network Performance Monitor). This means that the device or the SNMP agent does not have the information for that OID or does not respond to the SNMP request for that OID12.
To resolve this issue, you can try the following steps34:
Verify that the device supports the OID that you want to monitor. You can use the MIB Browser or the MIB Walk tool to browse the MIB tree of the device and find the OID. You can also check the device vendor's documentation or website for the supported OIDs and MIBs.
Verify that the SNMP agent on the device is configured properly and has the latest version. You may need to update the SNMP agent or enable some features or extensions to support the OID. You can also check the SNMP agent's logs or status for any errors or warnings.
Verify that the SNMP credentials and settings are correct and match the device's configuration. You may need to use a different SNMP version, community string, port, or timeout value to communicate with the device. You can also test the SNMP connectivityusing the SNMP Test tool or the Test button in the UnDP (Universal Device Poller) application.
Verify that there are no network issues or firewalls that are blocking the SNMP traffic between the NPM server and the device. You may need to allow the SNMP protocol and port on the firewall or router, or use a different network path or interface to reach the device. You can also use the Ping or Traceroute tools to check the network connectivity and latency.

NEW QUESTION # 65
You can apply Universal Device Pollers to which object types? (Choose all that apply.)
- A. Applications
- B. Interfaces
- C. Nodes
- D. Volumes
Answer: B,C,D
Explanation:
Universal Device Pollers (UnDPs) are custom pollers that allow you to monitor specific aspects of your network devices using SNMP. You can apply UnDPs to any object type that supports SNMP polling, such as interfaces, nodes, and volumes. You cannot apply UnDPs to applications, because they are not SNMP-based objects. Applications are monitored using Application Performance Monitor (APM), which uses different methods, such as WMI, scripts, or agents, to collect data.

NEW QUESTION # 66
NetPath can analyze paths to which network segments?
- A. Hybrid Networks
- B. Cloud Networks
- C. All of the above
- D. On-premise networks
Answer: C
Explanation:
NetPath is a feature of NPM that helps you identify network problems faster by automatically creating a map of the problem area, with a wide variety of supporting information. NetPath displays the performance details of devices inside and outside of your network. NetPath can analyze paths to any network segment, whether it is on-premise, cloud, or hybrid. NetPath uses distributed monitoring and path analysis to discover how applications are delivered through the network to your users. You can deploy agents on Windows computers that act as synthetic users and use advanced probing to discover and test the network path that traffic takes to any network endpoint, such as your local file print server, your website, or external websites. NetPath can also incorporate data from NPM, NCM, and NTA about your on-premises gear, as well as data from the Internet nodes and providers12.
