Question No 1:

Which three of the following actions are native log entry actions? (Choose three.)

A. add a tag to the log entry
B. continue rule processing but do not save
C. halt further rule processing for the log entry
D. send an email notification

Correct answer: A, B, C

Explanation:

In the context of log management and processing (commonly seen in security, network monitoring, or SIEM systems), native log entry actions refer to the predefined actions that can be applied to log entries during processing. These actions are typically part of the log processing workflow and define how logs should be handled, stored, or acted upon.

Let’s break down each option:

A. Add a tag to the log entry
This is a native action in many logging or monitoring systems. Adding tags to logs helps categorize or label log entries, making them easier to search, filter, and analyze later. Tags can be used to mark logs based on specific characteristics, such as severity or related processes.
B. Continue rule processing but do not save
This action is valid and often used in log management systems. It allows the log entry to continue through further rule checks without being saved to the log storage or database. This can be useful in scenarios where you need to apply some checks or filters to the log but do not want to store it permanently.
C. Halt further rule processing for the log entry
This is another native log action. When this action is applied, it stops the further processing of the log entry. This can be useful when a particular condition is met and no further processing is necessary or desired, for example, if a log entry has already been handled or flagged as critical.
D. Send an email notification
While sending email notifications is a common action in many systems, it is typically not considered a native log entry action in the sense of log entry management. It is more of a secondary action or an alerting function triggered by specific log entries but not part of the core log entry handling process. It is an action that is usually configured separately from native log entry actions.

In summary, the three actions that are native to log entry processing are:

A. Add a tag to the log entry
B. Continue rule processing but do not save
C. Halt further rule processing for the log entry

Question No 2:

If a NetFlow collector service is showing a “down” status, which two of the following steps are possible troubleshooting options? (Choose two.)

A. Confirm the database connection is up and server has free resources.
B. Delete and re-add NetFlow collector service.
C. Start or restart SolarWinds’ collector service.
D. Start or restart SolarWinds’ NetFlow service from Orion service manager.

Correct answers: A and C

Explanation:

When a NetFlow collector service is down, there are several potential causes, such as issues with the service itself, resource exhaustion, or connectivity problems. The following troubleshooting steps are relevant:

A. Confirm the database connection is up and server has free resources.
It’s essential to ensure that the database connection is functional because if the collector service cannot connect to the database, it may fail to start or remain down. Additionally, checking that the server has free resources (e.g., CPU, memory, and disk space) is crucial because resource constraints could prevent the NetFlow collector from starting or functioning properly.
C. Start or restart SolarWinds’ collector service.
If the collector service is down, restarting the service may help resolve the issue. Restarting can clear temporary issues or errors preventing the service from operating correctly. The SolarWinds NetFlow collector service is often the main service that handles data collection from flow sources, and restarting it can reinitialize the connection.

Now, let's review the other options:

B. Delete and re-add NetFlow collector service.
This option is typically a last resort. Re-adding the service might be useful if configuration files are corrupted or irreparable, but it’s not usually the first step for troubleshooting a “down” service.
D. Start or restart SolarWinds’ NetFlow service from Orion service manager.
This step is relevant only if the issue is specific to the NetFlow service itself, not just the collector. However, since the problem described is related to the collector service specifically, this option may not address the root cause of the issue.

Thus, the correct troubleshooting steps are to confirm the database connection and resources and restart the collector service, making options A and C the most appropriate choices.

Question No 3:

What is the minimum amount of RAM required for setting up log collection in hybrid cloud observability?

A. 4 GB
B. 8 GB
C. 16 GB
D. 32 GB

Answer: B

Explanation:

In a hybrid cloud observability setup, where log collection involves monitoring and managing logs across multiple cloud and on-premises environments, the system’s memory (RAM) plays a critical role in ensuring efficient log processing and storage.

4 GB of RAM is typically not sufficient for complex or large-scale log collection, as logs can generate substantial data that needs to be processed in real-time.
8 GB of RAM is generally considered the minimum for setting up log collection in a hybrid cloud observability solution. This amount allows the system to handle moderate log volumes, store data efficiently, and process logs without excessive delays or performance degradation.
16 GB and 32 GB of RAM would be recommended for larger environments or more intensive logging operations, but 8 GB is sufficient as the minimum requirement for typical hybrid cloud setups.

Therefore, 8 GB is the minimum amount of RAM required to set up log collection effectively in hybrid cloud observability, making B the correct answer.

Question No 4:

A universal device poller (UDP) was created on the main polling engine to collect CPU temperature for routers polled by the main polling engine and switches polled by the additional polling engine.

It is noted that statistics from the switches are missing. What is the likely cause of the missing statistics?

A. routers are not monitored on the additional polling engine
B. switches are not monitored in the additional polling engine
C. UDPs are tied to polling engine on which they are hosted
D. UDPs do not work with additional polling engines

Correct answer: C

Explanation:

Universal Device Pollers (UDPs) are tied to the specific polling engine where they are created. In this scenario, the UDP was created on the main polling engine to collect CPU temperature, but because switches are polled by the additional polling engine, the statistics from those switches are missing.

Here's a breakdown of why the other options are not correct:

A. Routers are not monitored on the additional polling engine – If routers were not monitored on the additional polling engine, it would not affect the switches' statistics. This is unrelated to the missing statistics for the switches.

B. Switches are not monitored in the additional polling engine – While this could be a potential issue, the problem described in the question indicates that the switches are polled by the additional polling engine, but the missing statistics are more likely due to the misconfiguration of the UDP.

C. UDPs are tied to polling engine on which they are hosted – This is the correct answer. Universal Device Pollers are specific to the polling engine they are hosted on. If the UDP was created on the main polling engine, it will not collect data from devices that are polled by the additional polling engine, such as the switches in this case. To fix this, the UDP should be created or replicated on the additional polling engine for the switches.

D. UDPs do not work with additional polling engines – This is incorrect. UDPs can work with additional polling engines; however, they need to be specifically created or configured on those additional engines to collect data from the devices they poll.

In summary, the missing statistics are due to the fact that UDPs are tied to the polling engine on which they are hosted, and since the switches are polled by the additional polling engine, the UDP on the main polling engine cannot collect data for those switches.

Question No 5:

A probe is to be built to test connections to Office 365 from two different locations. How would this be accomplished?

A. Create a probe, duplicate it, and change the source agent to the agent in another location.
B. Create both probes on hybrid cloud observability (HCO) server and designate each location.
C. Create two probes and assign each to an agent in each location.
D. Create two probes and assign each to an agent in one location.

Answer: C

Explanation:

When testing connections to Office 365 from multiple locations, you need to ensure that separate probes are created for each location, with each probe associated with a distinct source agent from the respective locations. This ensures that the testing is performed from the correct geographic points and reflects the network conditions from each location.

Option A: "Create a probe, duplicate it, and change the source agent to the agent in another location" — This approach could technically work, but it’s not as efficient or clear as creating distinct probes for each location. Changing the source agent after duplicating can lead to confusion and possible misconfiguration. It's better to directly assign each probe to a dedicated agent for clarity and management.
Option B: "Create both probes on hybrid cloud observability (HCO) server and designate each location" — While using a Hybrid Cloud Observability (HCO) server could be relevant in some network monitoring tools, this option is more specific to a particular monitoring platform and doesn't universally apply to the general task of building probes for multiple locations. The key is assigning probes to agents in different locations.
Option C: "Create two probes and assign each to an agent in each location" — This is the best solution. It directly addresses the need to test from two separate locations by creating two independent probes, each tied to an agent located in one of those locations. This ensures that testing happens from both locations independently, providing more accurate and geographically relevant data.
Option D: "Create two probes and assign each to an agent in one location" — This option would not work because the goal is to test from two different locations. Assigning both probes to agents in a single location would defeat the purpose of testing from multiple points.

In conclusion, Option C is the best approach, as it ensures that each probe is tied to an agent in a separate location, allowing for testing connections to Office 365 from both locations.

Question No 6:

Flow data is not generating from a device in the web console. Wireshark was used to confirm the flows are being sent from the device to the poller and not blocked by the firewall. Why is the data not showing in the web console?

A. Device is not monitored by hybrid cloud observability (HCO) features
B. Device is using IPv6 and HCO only supports IPv4
C. Missing source address field in flow configurations
D. Flow monitoring was not enabled as device type in web console settings

Answer: D

Explanation:

The issue described involves flow data not showing in the web console, even though Wireshark confirms that the flows are being sent from the device to the poller and are not blocked by the firewall. This suggests that the data is reaching the poller, but there may be an issue with how the flow data is processed or displayed in the web console.

Let’s analyze each option:

A. Device is not monitored by hybrid cloud observability (HCO) features: This would affect monitoring at a broader level, but it doesn't explain why flows are not showing in the web console specifically. HCO features relate to overall monitoring but don’t directly influence flow data visibility unless there's a specific configuration missing for flow data.
B. Device is using IPv6 and HCO only supports IPv4: If this were the case, flow data using IPv6 would not be compatible with the web console. However, it’s unlikely that the device is only using IPv6 when Wireshark confirms that the flows are reaching the poller. Modern network monitoring systems usually support both IPv4 and IPv6, so this is not the most likely cause.
C. Missing source address field in flow configurations: While this could potentially cause flow data to be incomplete or improperly formatted, it doesn't seem to be the main reason the data isn’t appearing in the web console. Wireshark confirmed that the flow data is being sent correctly, which suggests that the flow data is formatted and reaching the poller properly.
D. Flow monitoring was not enabled as device type in web console settings: This is the most plausible explanation. If the web console settings are not configured to recognize the device as a flow source (or if flow monitoring is not enabled for the specific device type), the flow data will not be processed or displayed in the web console, even though it is being received by the poller. Therefore, the administrator would need to ensure that the web console is properly configured to monitor and display flow data from the specific device type.

Therefore, D is the correct answer because it directly addresses the issue of flow data not being displayed in the web console due to the settings configuration.

Question No 7:

Which two of the following tasks must be accomplished to monitor servers and connections in a load-balancing environment? (Choose two.)

A. Add Cisco Nexus device in network device configuration manager
B. Add Cisco Nexus device in network health/performance monitoring
C. Enable CLI polling
D. Enable F5 iControl polling

Answer: B, D

Explanation:

To monitor servers and connections in a load-balancing environment, certain configurations must be made to ensure that the network health, performance, and load balancing operations are being monitored effectively. Here's why the selected answers are correct:

B. Add Cisco Nexus device in network health/performance monitoring: In a load-balancing environment, monitoring the health and performance of network devices (such as Cisco Nexus switches) is critical. Adding the device to a monitoring system (such as Cisco Prime or other monitoring solutions) allows you to track the device's status, network performance, and its role in the overall network. This ensures that any network issues, like high latency or device failure, are detected and managed promptly.
D. Enable F5 iControl polling: If F5 devices (which are typically used for load balancing and application delivery) are part of the environment, enabling iControl polling allows monitoring of those devices through their iControl API. This polling provides visibility into the performance of load balancers, servers, and connections, helping ensure proper traffic distribution and load balancing.

Now, let's break down the incorrect answers:

A. Add Cisco Nexus device in network device configuration manager: While adding Cisco Nexus devices to a network device configuration manager (like Cisco Prime Infrastructure) may be necessary for configuration management and deployment, it is not specifically required for monitoring servers and connections in a load-balancing environment. This task is more relevant for configuration management than for monitoring.
C. Enable CLI polling: CLI polling (command-line interface polling) typically involves polling a device through its CLI for data collection. While this could potentially be used for monitoring, it is not as efficient or scalable as using specific protocols or APIs like F5 iControl for load balancers or integrated monitoring solutions that provide better visibility into load balancing and network health.

Therefore, the correct tasks to monitor servers and connections in a load-balancing environment are B and

Question No 8:

What is a possible result of decreasing the top talking optimization value?

A. increased storage requirement
B. reduced database performance
C. reduced page load times
D. slower reporting speed

Answer: B

Explanation:

The top talking optimization value is typically related to performance tuning, specifically in scenarios where database or application performance optimizations are involved. In many cases, optimization values impact how resources are allocated or how frequently certain processes are executed.

Let’s analyze the options based on a general understanding of performance tuning and optimizations:

A. Increased storage requirement:
Decreasing the top talking optimization value would not directly cause an increase in storage requirements. In fact, optimization changes typically affect how efficiently data is handled or processed rather than how much storage is used. This option is less likely to be the result of decreasing this value.
B. Reduced database performance:
Decreasing the top talking optimization value could cause the system to work less efficiently, resulting in reduced performance. Optimizations like this are often designed to improve performance by reducing the complexity of queries or operations. By lowering the optimization value, you may be introducing more overhead or less efficient handling of requests, which leads to performance degradation, such as longer query times and slower data processing.
C. Reduced page load times:
This option suggests that the optimization value is directly related to improving page load times. However, decreasing the optimization value usually has the opposite effect — it may lead to slower load times as the system becomes less optimized in handling the data or requests. Therefore, this result is unlikely.
D. Slower reporting speed:
While slower reporting could be a side effect of reduced performance, it is a more indirect result compared to reduced database performance. Reports depend on database queries, and if those queries become less optimized, the reporting speed could indeed suffer, but the more direct and primary effect is reduced database performance.

In conclusion, the most probable and direct effect of decreasing the top talking optimization value is reduced database performance, as optimizations are typically in place to enhance database efficiency and query handling. Therefore, the correct answer is B.

Question No 9:

Which two of the following troubleshooting steps can be performed when a node is “up” and the data cannot be found in SolarWinds’ platform web console? (Choose two.)

A. Add a remote site node and make sure the firewall rules are configured to allow SNMP traffic.
B. Ping the device from the polling engine the device is assigned to using the command line.
C. Verify hardware health sensors on the device provide both status and values.
D. Wait ten minutes after a device is added to the console. Refresh the screen.

Answer: B and D

Explanation:

In the context of troubleshooting when a node is "up" but data is not visible in SolarWinds' platform web console, there are a few steps that can help diagnose the issue. Let’s break down the two correct options:

B. Ping the device from the polling engine the device is assigned to using the command line:
This is a valid troubleshooting step. If the node is "up" but data is not being retrieved, one possibility is that the polling engine is unable to communicate with the node. Using the command line to ping the device from the polling engine can verify if there are any connectivity issues (such as network problems or firewall rules) that could be preventing the data from being collected and displayed. This helps confirm if the node is actually reachable from the polling engine.
D. Wait ten minutes after a device is added to the console. Refresh the screen:
When a device is added to the SolarWinds platform, it may take some time for the data to populate in the console. Waiting for a short period (such as ten minutes) and then refreshing the screen is a reasonable step to ensure that the data collection process has had enough time to complete. It's not uncommon for the data to be delayed slightly after the node is added, especially if it's still in the process of gathering and processing the required information.

Now, let’s analyze why the other options are not correct:

A. Add a remote site node and make sure the firewall rules are configured to allow SNMP traffic:
While SNMP traffic is crucial for SolarWinds to collect data from devices, adding a "remote site node" and configuring firewall rules is not directly related to troubleshooting why data isn’t appearing for a node that is already "up" in the console. This step might be relevant if you are dealing with a remote site, but it’s not necessary when the node is already added and accessible in the console.
C. Verify hardware health sensors on the device provide both status and values:
This step focuses on verifying hardware health, which is useful for ensuring the device's physical status is being monitored correctly. However, if the node is "up" in the SolarWinds platform, it generally indicates that the device is reachable. This step is less likely to resolve the issue of missing data in the console, especially if the node is already reporting up status.

Thus, the correct answers are B and D. These steps are directly relevant for troubleshooting data visibility issues in SolarWinds when a node is "up."

Question No 10:

Which tool can be used to display the physical layout of interfaces on graphical stencils?

A. device studio
B. device view
C. NetPath
D. network insight

Answer: B

Explanation:

The Device View tool is used to display the physical layout of interfaces on graphical stencils. This tool allows users to visualize the network topology and the connections between various network devices. It helps in understanding how the interfaces are physically laid out on the devices, which is essential for troubleshooting, network design, and documentation purposes.

A. Device studio is typically used for designing or configuring devices, but it does not focus on displaying the physical layout of interfaces.
C. NetPath is a network troubleshooting tool that visualizes the path that data takes across the network, but it does not specifically display the physical interface layout.
D. Network Insight is generally used for monitoring and analytics, providing visibility into network health and performance but is not specifically used for graphical interface layout visualization.

Thus, B. Device View is the correct tool for displaying the physical layout of interfaces on graphical stencils.
