VNX100 Versa Networks Practice Test Questions and Exam Dumps

Question 1

In a Versa Secure SD-WAN solution, what are three functions of a hub controller? (Choose three.)

A. It does CPE lifecycle management.
B. It is a control plane node.
C. It is a data plane node.
D. It provides visibility and control.
E. It can be a staging server.

Correct Answers: A, B, D

Explanation
In a Versa Secure SD-WAN architecture, the hub controller plays a crucial role in managing and orchestrating network services. SD-WAN solutions like Versa's are designed to simplify WAN management, provide centralized control, and enhance performance, security, and visibility across distributed networks. The hub controller is central to this by providing key functions related to network intelligence, control, and operations.

Let’s analyze each of the options to understand why A, B, and D are correct:

A. It does CPE lifecycle management.
This is correct. The hub controller in Versa Secure SD-WAN is involved in managing Customer Premises Equipment (CPE), including onboarding, configuration, firmware updates, and policy deployment. This lifecycle management ensures that the devices are properly managed from deployment to decommissioning. This is a vital function for scalable and centralized network administration.

B. It is a control plane node.
Also correct. One of the primary roles of a hub controller is to function as a control plane entity. It handles routing intelligence, path selection, policy application, and other decision-making functions. By separating the control plane from the data plane, Versa enhances flexibility and simplifies network operations.

C. It is a data plane node.
Incorrect. The hub controller does not act as a data plane node. In SD-WAN architecture, the data plane is responsible for the actual forwarding of traffic, which is typically handled by branch CPEs or gateways, not by the controller. The controller is focused on orchestration and control plane decisions, not traffic transport.

D. It provides visibility and control.
Correct. The Versa hub controller enables network-wide visibility and policy control, which includes traffic analytics, device status, performance monitoring, and policy enforcement. This centralized visibility allows administrators to diagnose issues and optimize network performance from a single pane of glass.

E. It can be a staging server.
Incorrect. A staging server is typically used during device onboarding for tasks like pushing configuration templates or performing initial authentication. While a controller might coordinate with a staging server, it is not itself a staging server in the Versa architecture. The roles are distinct.

In summary, the hub controller in Versa Secure SD-WAN handles CPE lifecycle management, acts as a control plane node, and provides centralized visibility and control across the SD-WAN fabric. It does not perform data forwarding or act as a staging server.

Thus, the correct answers are A, B, and D.

Question 2

You have set up a Versa Secure SD-WAN solution using a Full Mesh topology. Based on this configuration, which of the following statements is true?

A. The CPE devices send SLA probes on the active forwarding path only.
B. The CPE devices send SLA probes on all possible transport paths between devices.
C. The CPE devices send SLA probes to the Versa Controller, and the Versa Controller distributes active site statistics to other CPEs.
D. The CPE devices send SLA probes to the Versa Controller, and the Versa Controller relays the probes to CPE devices.

Correct Answer : B

Explanation:

In a Versa Secure SD-WAN Full Mesh topology, Customer Premises Equipment (CPE) devices are interconnected directly with each other over all available transport paths. This architecture is designed to provide optimal routing, redundancy, and dynamic path selection based on real-time performance metrics.

One of the fundamental features of Versa SD-WAN is the ability to make forwarding decisions based on SLA (Service Level Agreement) metrics, such as latency, jitter, packet loss, and bandwidth. To measure these metrics, Versa uses SLA probes—small data packets that simulate traffic between CPEs to assess the quality of each possible path.

In a Full Mesh topology, each CPE has the potential to communicate directly with every other CPE across multiple transport networks (e.g., MPLS, broadband, LTE). Therefore, to evaluate all potential communication paths, each CPE sends SLA probes across all possible transport paths to all its peers. This allows each CPE to build a comprehensive view of network performance and make intelligent forwarding decisions based on current path conditions.

Let’s analyze why option B is correct and the others are not:

Why B is correct:

• In Versa’s SD-WAN implementation, SLA probes are sent across every available transport tunnel between CPE devices.

• This allows Versa to monitor real-time performance across all links, enabling the system to reroute traffic dynamically if any degradation is detected.

• The probes ensure that the SD-WAN fabric can react to changes in path quality across any pair of CPEs in the network.

Why the other options are incorrect:

A. The CPE devices send SLA probes on the active forwarding path only.
This is incorrect because monitoring only the active path would prevent the system from detecting improvements or degradations on alternative paths. Versa SD-WAN continuously monitors all paths, not just the currently active one, to support real-time dynamic path switching.

C. The CPE devices send SLA probes to the Versa Controller, and the Versa Controller distributes active site statistics to other CPEs.
This implies a centralized probing mechanism, which does not align with Versa's architecture. Versa uses a distributed model, where each CPE sends its own probes to its peers. The controller is typically not involved in distributing real-time performance metrics among CPEs.

D. The CPE devices send SLA probes to the Versa Controller, and the Versa Controller relays the probes to CPE devices.
Again, this describes a relay architecture, which is not how Versa implements SLA monitoring. SLA probes are sent directly between CPEs, without the controller acting as a relay or intermediary.

In Versa Secure SD-WAN’s Full Mesh topology, each CPE must evaluate every potential path to its peers, which requires sending SLA probes over all transport links. This distributed probing model ensures accurate and dynamic path selection based on the best available network conditions.

Therefore, the correct answer is B.

Question 3

A customer has a single Versa Analytics cluster deployed in a data center. The Versa Director and Versa Controller nodes are distributed between the data center and the disaster recovery sites. The data center goes down for one day. In this scenario, 

Which statement is true?

A. SD-WAN CPE live monitoring will be lost during the one-day downtime.
B. New SD-WAN CPE cannot be deployed during the one-day downtime.
C. Reachability between SD-WAN CPE will be lost during the one-day downtime.
D. Logging and reporting will be lost during the one-day downtime.

Correct answer: D

Explanation:

This scenario describes a Versa Secure SD-WAN architecture with high availability, where the Versa Director and Controller nodes are distributed across both the main data center and a disaster recovery (DR) site. However, Versa Analytics — the component responsible for collecting and storing logs, statistics, and generating reports — is hosted only in the data center and is not distributed or backed up to the DR site.

Let’s evaluate the implications and analyze each option:

A. SD-WAN CPE live monitoring will be lost during the one-day downtime.
This is not entirely accurate. While Versa Analytics enables long-term monitoring, alerts, and historical visibility, real-time status of SD-WAN CPEs is still available through Versa Director and Controller, provided those are operational (which they are, since they are distributed to the DR site). Monitoring capabilities that depend on analytics-driven dashboards and metrics would be impaired, but basic live status, configuration, and control functions would remain. Therefore, this statement is misleading.

B. New SD-WAN CPE cannot be deployed during the one-day downtime.
This is false. New CPEs can still be deployed as long as Versa Director and Controller are reachable and functional. These two components handle the provisioning, configuration, and orchestration of CPEs. Since they are distributed and at least one instance is at the DR site, the customer can still deploy new devices during the outage. Versa Analytics is not involved in provisioning — it only deals with logging, telemetry, and reporting.

C. Reachability between SD-WAN CPE will be lost during the one-day downtime.
This is also incorrect. CPEs (Customer Premises Equipment) form a data plane mesh that allows them to maintain connectivity even in the absence of control plane elements. Once the SD-WAN overlay tunnels are established, they are maintained independently of the data center’s availability. Since the Versa Controllers are active from the DR site, routing and control policies are still enforced, and traffic between CPEs continues to flow.

D. Logging and reporting will be lost during the one-day downtime.
This is the correct answer. Since Versa Analytics — the component responsible for collecting telemetry, system logs, performance stats, and producing reports — is hosted only in the data center, its outage means that no logging or reporting will take place during that period. The logs generated by the CPEs and other infrastructure components will not be captured or archived during the downtime. Depending on retention policies on the devices, some data may be recoverable post-restoration, but real-time analytics and dashboards will be unavailable.

Versa Analytics is critical for storing and analyzing logs, generating reports, and visualizing trends. If the data center hosting it goes down and no backup exists at the DR site, all logging and reporting functions will be lost until it is restored. The rest of the SD-WAN infrastructure (including provisioning and connectivity) remains functional, assuming redundancy is correctly configured for the Director and Controller nodes.

Correct answer: D

Question 4

What is the default load balancing algorithm set in an SD-WAN Forwarding Profile?

A. High Available Bandwidth
B. Per Packet
C. Weighted Round Robin
D. Per Flow

Correct Answer: D

Explanation
In SD-WAN solutions, especially in enterprise-grade platforms like Palo Alto Networks, Fortinet, Versa, and Cisco SD-WAN, Forwarding Profiles (also known as Traffic Steering Profiles or Traffic Distribution Policies) define how traffic is distributed across multiple WAN links. These profiles dictate how the SD-WAN fabric handles load balancing and redundancy to maximize performance and reliability.

The default load balancing algorithm that is typically configured in a forwarding profile is Per Flow.

Let’s break down what each of these options means and why Per Flow is the default:

A. High Available Bandwidth
This algorithm attempts to route traffic across the path with the most available bandwidth at a given moment. While effective in optimizing link utilization, it is not usually the default due to the extra computational and monitoring overhead it imposes. It is often an optional or advanced setting rather than a default.

B. Per Packet
In Per Packet load balancing, individual packets from the same session can be sent over different paths. Although this method maximizes link utilization and may balance traffic more finely, it introduces potential issues with packet reordering, which can degrade performance for latency-sensitive applications like voice or video. Hence, it is not commonly used as the default.

C. Weighted Round Robin
This method distributes traffic proportionally across links based on assigned weights. While it's a very balanced and predictable algorithm, it is not typically the default unless an administrator explicitly sets it up that way. It's commonly used in scenarios with links of unequal bandwidth but is not the out-of-box configuration.

D. Per Flow
This is the correct answer and the default algorithm in many SD-WAN solutions' forwarding profiles. In Per Flow load balancing, each flow (or session) is assigned to a specific path, and all packets in that flow follow the same route. This preserves packet order and reduces jitter, which is critical for real-time applications like VoIP, video conferencing, and transactional traffic.

Per Flow is also computationally efficient and works well under most conditions without needing complex link monitoring or real-time bandwidth evaluation. Because of its stability, reliability, and performance consistency, SD-WAN vendors choose it as the default setting.

In summary, the Per Flow algorithm offers a balanced trade-off between performance, simplicity, and compatibility with a wide variety of applications, making it the standard load balancing method in SD-WAN forwarding profiles.

Thus, the correct answer is D.

Question 5

As the administrator of a Versa Secure SD-WAN network, you need to implement a new URL filtering profile on all SD-WAN CPEs in response to a recent security incident. 

Which configuration template should you use to apply URL filtering?

A. QoS Template
B. Stateful Firewall Template
C. NexGen Firewall Template
D. Common Template

Correct Answer : C

Explanation:

In the Versa Secure SD-WAN solution, configuration management is modular and template-driven. Each type of template addresses a specific category of network functionality, allowing administrators to assign and manage settings across devices in a structured and scalable way. URL filtering, a core feature of modern network security, is part of Versa’s Next-Generation Firewall (NGFW) capabilities.

The correct template to apply when configuring URL filtering is the NexGen Firewall Template (option C). This template contains all the advanced security features expected of an NGFW, such as:

• Application identification and control

• Threat detection and prevention

• Intrusion prevention system (IPS)

• URL filtering

• Anti-virus scanning

• SSL decryption and inspection

When a URL filtering profile is needed—for example, to block access to malicious or inappropriate websites—administrators define this profile under the NexGen Firewall Template and then apply it to the relevant policies. This ensures that web access is controlled in accordance with organizational security policies, and any risky or unauthorized activity can be blocked in real time.

Let’s break down why each of the other options is not suitable:

A. QoS Template:
This template is used for Quality of Service configurations, such as traffic prioritization, bandwidth shaping, and class-based queuing. It deals with performance management, not security. URL filtering has no relation to QoS settings, so this is not the correct choice.

B. Stateful Firewall Template:
This template supports basic Layer 4 firewall functionality, such as allowing or denying traffic based on IP addresses, ports, and protocols. While it can enforce connection-based filtering, it does not include application-layer inspection or advanced content-based features like URL filtering. URL filtering specifically requires application-layer awareness, which is only available in the Next-Generation Firewall template.

D. Common Template:
The Common Template is used to define shared settings such as device-level configurations, interfaces, routing protocols, and basic system services. It is useful for general infrastructure setup but does not include advanced security features like URL filtering. Therefore, it is not suitable for this purpose.

Summary:
To implement URL filtering across SD-WAN CPEs in Versa, you must use the NexGen Firewall Template, which includes all application-layer and security-focused functionalities. URL filtering is a part of Versa’s advanced threat protection stack, requiring deep packet inspection and classification capabilities only available in this template.

Therefore, the correct answer is C.

Question 6

A network operator wants to monitor a Versa CPE interface live data. In this scenario, how would you accomplish this task?

A. using Versa Controller
B. using Versa Director
C. using Versa Analytics
D. using the Versa CPE GUI

Correct answer: B

Explanation:

This question focuses on the task of monitoring live data for a Versa CPE interface, which involves accessing real-time statistics such as interface utilization, throughput, errors, or latency directly from the network device. To determine the best tool for this task, we need to understand the roles and capabilities of each Versa component.

Let’s analyze each option:

A. using Versa Controller
The Versa Controller is primarily a control plane element responsible for managing SD-WAN routing, overlay creation, and network control policies. It does not provide a direct interface for operational tasks such as real-time monitoring of CPE interfaces. The controller helps enforce configuration and policy distribution but is not used for live data visualization. So, this is not the correct choice.

B. using Versa Director
The Versa Director is the primary management interface for Versa Secure SD-WAN. It is used for:

• Configuration and provisioning of CPEs

• Real-time operational monitoring of CPE devices

• Viewing live interface statistics and system health

• Accessing logs and alerts (if analytics is integrated)

Versa Director provides live monitoring capabilities, allowing operators to view real-time interface data such as bandwidth usage, errors, and packet statistics directly from the CPE. This makes it the ideal tool for network operators needing to observe live traffic and status information on deployed CPEs.

C. using Versa Analytics
Versa Analytics is focused on historical data collection, analysis, and reporting. It gathers telemetry from CPEs and other components, stores it in a time-series database, and presents it in dashboards for trend analysis, SLA reporting, and capacity planning. While Versa Analytics is very powerful for long-term insights, it does not provide real-time operational data or granular, live interface monitoring. Thus, it is not suitable for this specific task.

D. using the Versa CPE GUI
Versa CPEs may offer local GUI access, but this is typically reserved for troubleshooting or limited administrative access. Although some real-time statistics may be available through the local interface, using the CPE GUI is not the recommended or scalable approach for operational teams, especially in environments managing many CPEs. Versa Director provides centralized and efficient access for monitoring many devices, whereas the local CPE GUI is more for isolated diagnostics. Hence, this is not the best method.
For live monitoring of Versa CPE interface data, Versa Director is the proper tool. It provides centralized, real-time visibility and control over deployed CPEs, including interface statistics and operational state. This makes it essential for network operators managing SD-WAN environments.

Correct answer: B

Question 7

Which two descriptions about CoS functions in a Versa branch are true? (Choose two.)

A. Remarking separates traffic based on Layer 3, Layer 4, and Layer 7 fields.
B. Classification alters the CoS fields in outgoing traffic.
C. Queuing defines the priority of traffic and weights.
D. Scheduling controls the order of packets sent.

Correct Answers: C and D

Explanation
In a Versa branch within an SD-WAN solution, Class of Service (CoS) functions are critical for managing and prioritizing network traffic. These CoS functions ensure that the right type of traffic gets the appropriate level of service, improving the quality of experience for time-sensitive or mission-critical applications. Let’s review each option to see which two descriptions are true:

A. Remarking separates traffic based on Layer 3, Layer 4, and Layer 7 fields.

• Incorrect. Remarking in the context of CoS refers to the modification of the CoS values (such as the DSCP or MPLS EXP) on existing packets, but it does not focus on separating traffic based on Layer 3, Layer 4, or Layer 7 fields. Instead, it modifies the existing CoS markings to reflect the correct prioritization after traffic has been classified.

• Remarking is about re-tagging packets to indicate their priority or service requirements, not separating them based on protocol layers. Therefore, this statement is incorrect.

B. Classification alters the CoS fields in outgoing traffic.

• Incorrect. Classification refers to the process of identifying traffic and assigning it to specific categories or classes based on its characteristics (e.g., source IP, destination, application type). While this process uses Layer 3, 4, and 7 information, it does not alter the CoS fields directly. Classification assigns a CoS value based on defined policies but does not modify traffic like remarking does. Therefore, this statement is incorrect.

C. Queuing defines the priority of traffic and weights.

• Correct. Queuing is an essential CoS function that defines how traffic is treated in terms of priority and allocation of resources. In SD-WAN, queues are used to manage how traffic is buffered and scheduled based on its importance and service requirements. Higher-priority traffic (e.g., voice or video) will be given priority over lower-priority traffic (e.g., bulk data). Queuing may involve assigning weights to different traffic types, which determines how much bandwidth each queue gets. Therefore, this statement is correct.

D. Scheduling controls the order of packets sent.

• Correct. Scheduling is the CoS function that controls the transmission order of packets from different queues. It determines which packets are sent first based on their priority or weight, ensuring that higher-priority traffic is transmitted before lower-priority traffic. Scheduling algorithms control the order in which packets from different queues are processed and forwarded, which is critical for ensuring that real-time applications (e.g., voice and video) receive the necessary bandwidth and low latency. Therefore, this statement is correct.

In summary, Queuing and Scheduling are key functions that handle the priority and order of traffic in an SD-WAN environment. Therefore, the correct answers are C and D.

Question 8

Which two statements are accurate regarding the live monitoring capabilities for Versa CPEs in a Versa SD-WAN environment? (Choose two.)

A. Versa Analytics provide real-time monitoring capabilities for all services running in Versa CPE.
B. Versa Director provides real-time monitoring capabilities for all services running in Versa CPE.
C. Versa Analytics has built-in ping, traceroute, tcpdump, and speed test tools.
D. Versa Director has built-in ping, traceroute, tcpdump, and speed test tools.

Correct Answer : A and D

Explanation:

In a Versa Secure SD-WAN deployment, two central components—Versa Analytics and Versa Director—play critical roles in monitoring, managing, and troubleshooting Customer Premises Equipment (CPE) devices across the SD-WAN fabric.

Understanding what each component does is essential for choosing the correct statements:

Versa Analytics

Versa Analytics is primarily responsible for collecting, processing, and visualizing telemetry and performance data from all CPE devices. It provides powerful, real-time and historical monitoring capabilities for a wide range of metrics, including:

• Application usage

• Interface statistics

• Link performance (latency, jitter, packet loss)

• Security event logs

• SLA compliance metrics

So, statement A is correct because Versa Analytics does provide real-time monitoring for services and traffic behavior across the entire network. It supports dashboards and reports that reflect current device status and ongoing activity.

However, Versa Analytics does not include active troubleshooting tools like ping or traceroute. It is mostly a passive telemetry engine, which disqualifies statement C.

Versa Director

Versa Director serves as the centralized network management and orchestration tool for Versa SD-WAN. In addition to managing policies, templates, and configurations, Versa Director includes live troubleshooting tools, such as:

• Ping

• Traceroute

• Tcpdump

• Speed tests

These tools are built into the UI and can be executed directly against remote CPE devices, which is particularly useful during diagnostics or incident response.

Therefore, statement D is correct—Versa Director does have built-in ping, traceroute, tcpdump, and speed test capabilities, all of which are crucial for active troubleshooting and real-time diagnostics.

Now, let’s look at the incorrect statements:

B. Versa Director provides real-time monitoring capabilities for all services running in Versa CPE.
This is partially true but not entirely accurate. Versa Director does provide visibility into device status and certain logs, but it is not the primary tool for deep, continuous real-time monitoring of traffic and performance metrics. That responsibility belongs to Versa Analytics. Versa Director’s monitoring is more oriented toward configuration state and operational status rather than rich analytics.

C. Versa Analytics has built-in ping, traceroute, tcpdump, and speed test tools.
This is incorrect. While Versa Analytics gives a deep view into network and security data, it does not provide active network testing tools. Those are found in Versa Director.

Summary:

• Versa Analytics provides real-time and historical monitoring of services and traffic metrics, but it doesn’t offer active tools like ping or traceroute.

• Versa Director is used for network orchestration and configuration, and it also provides built-in live diagnostic tools like ping and tcpdump.

Therefore, the correct answers are A and D.
