Versa Networks VNX100 Exam Dumps & Practice Test Questions

Question 1:

Within a Versa Secure SD-WAN deployment, which three responsibilities are performed by the hub controller? (Choose three.)

A. Managing the lifecycle of CPE devices
B. Operating as part of the control plane
C. Serving as a data plane entity
D. Delivering centralized visibility and control
E. Functioning as a staging server during onboarding

Correct Answers: A, B, D

Explanation:

In Versa Secure SD-WAN, the hub controller is a pivotal component that facilitates centralized management, orchestration, and operational intelligence across the SD-WAN environment. Its role aligns with the principles of software-defined networking by abstracting control functionality from data forwarding and enabling dynamic, scalable WAN architectures.

Let’s explore the correct choices first:

A. Managing the lifecycle of CPE devices
Yes, this is accurate. The hub controller is deeply involved in Customer Premises Equipment (CPE) lifecycle management, which includes onboarding, configuration, monitoring, updating firmware, and policy application. These tasks are essential for ensuring CPE devices are correctly integrated into the SD-WAN fabric from deployment to decommissioning. Centralized CPE lifecycle management simplifies operations, particularly in large-scale distributed environments.

B. Operating as part of the control plane
This is also true. The hub controller is a control plane node responsible for making key decisions about routing, policy enforcement, and security services. It gathers real-time data and enforces centralized policies across branch devices. By separating control plane functionality from the data plane, Versa ensures scalability, easier maintenance, and enhanced visibility.

D. Delivering centralized visibility and control
Absolutely. One of the hub controller’s core strengths is offering network-wide visibility and control. This includes monitoring performance metrics, traffic patterns, device health, and enforcing security or QoS policies. Administrators can gain insights from a centralized dashboard and respond proactively to network anomalies or outages.

Now, let’s rule out the incorrect options:

C. Serving as a data plane entity
Incorrect. The data plane is responsible for forwarding user traffic and resides in CPEs or gateways. The hub controller operates purely in the control plane, managing orchestration and not the actual data traffic. Routing decisions are passed to data plane devices, which act accordingly.

E. Functioning as a staging server
Also incorrect. A staging server is typically used during device onboarding to provision initial configurations or validate authentication. While a hub controller may interact with the staging server, it does not assume that role. The responsibilities and workflows of the hub controller and staging server are distinct.

In summary, the Versa Secure SD-WAN hub controller performs essential roles in control plane operations, centralized management, and lifecycle handling of CPE devices, making A, B, and D the correct selections.

Question 2:

In a Versa SD-WAN environment using a Full Mesh topology, which statement best describes how SLA probes function?

A. CPE devices monitor only the currently active path using SLA probes
B. CPE devices send SLA probes across every transport path to peer CPEs
C. CPE devices transmit SLA probes to the controller, which distributes statistics
D. CPEs send probes to the controller, which relays them to peer devices

Correct Answer: B

Explanation:

In Versa Secure SD-WAN, the use of SLA (Service Level Agreement) probes is central to its ability to dynamically steer traffic based on real-time network performance. When deployed in a Full Mesh topology, all Customer Premises Equipment (CPE) devices are directly interconnected through multiple transport links (such as MPLS, broadband, or LTE). This setup allows for multiple routing options between sites, with Versa continuously evaluating path performance to optimize routing.

Why B is correct:
In a Full Mesh environment, each CPE device sends SLA probes over every possible transport path to each peer CPE. These probes are small packets that test latency, jitter, packet loss, and throughput. The CPEs use the collected metrics to evaluate the health of all potential paths and dynamically determine the optimal route for forwarding data. This distributed path monitoring allows Versa SD-WAN to adapt to changing network conditions in real time.

Let’s evaluate the incorrect choices:

A. CPE devices monitor only the currently active path using SLA probes
This is incorrect. Monitoring only the active path would limit the system’s ability to detect degradation on alternate links. Versa SD-WAN proactively monitors all paths—even if they’re currently unused—to ensure it can switch to a better path when needed. Dynamic path selection depends on having performance data for all options.

C. CPE devices transmit SLA probes to the controller, which distributes statistics
Incorrect. Versa uses a distributed model for SLA monitoring. Each CPE independently sends and receives probes without relying on the controller to coordinate or relay probe results. The controller plays a broader orchestration role but is not in the direct path of SLA data collection or dissemination.

D. CPEs send probes to the controller, which relays them to peer devices
Also incorrect. This describes a centralized probing architecture, which does not reflect how Versa SD-WAN operates. Probes are sent directly between CPE devices. Relaying probes through a controller would add unnecessary latency and complexity.

In conclusion, option B accurately reflects the Versa SD-WAN approach in a Full Mesh setup, where each CPE continuously probes all available paths to its peers. This model enables the intelligent, SLA-aware routing that defines a robust SD-WAN deployment.

Question 3:

A customer has deployed a single Versa Analytics cluster in their primary data center, while Versa Director and Controller nodes are distributed between the main site and a disaster recovery (DR) location.

If the data center becomes unavailable for one day, which of the following outcomes is accurate?

A. Live monitoring of SD-WAN CPE devices will be lost.
B. New SD-WAN CPE devices cannot be provisioned.
C. SD-WAN CPE devices will lose connectivity with each other.
D. Logging and reporting functionality will be unavailable.

Correct Answer: D

Explanation:

In this scenario, we are dealing with a Versa Secure SD-WAN deployment that features high availability for control plane elements such as the Versa Director and Versa Controller, but not for Versa Analytics, which is hosted solely in the primary data center. The Versa Analytics platform is responsible for logging, telemetry collection, reporting, and long-term analytics.

If the primary data center experiences an outage, the Versa Analytics cluster becomes unreachable. As a result, all functionalities that depend on the analytics component—including log collection, trend visualization, alert reporting, and analytics dashboards—will be lost for the duration of the downtime. Events generated during that one-day period will not be stored or accessible through Analytics, although some telemetry data may still reside temporarily on the devices themselves, depending on local buffering and log retention configurations.

Let’s examine the incorrect options:

• A. Live monitoring of SD-WAN CPEs will be lost – This is not entirely true. Live operational monitoring (status, configuration, tunnel state) can still be accessed through the Versa Director and Controller, especially since those components are distributed and at least partially functional from the DR site. Real-time monitoring that does not depend on Analytics will continue to work.

• B. New CPEs cannot be deployed – Incorrect. Versa Director and Controller manage the orchestration and provisioning of new Customer Premises Equipment (CPE). Since these components are operational from the DR site, new CPEs can still be onboarded and deployed.

• C. CPEs will lose connectivity – False. Once SD-WAN tunnels are established, CPEs communicate directly using overlay tunnels that are independent of the control and analytics planes. Traffic between them continues unaffected.

Conclusion:
The only correct statement is that logging and reporting capabilities are lost during the data center outage, due to the unavailability of the Analytics cluster.

Question 4:

In a standard SD-WAN Forwarding Profile, what is the default method used to load balance traffic across multiple WAN links?

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

Correct Answer: D

Explanation:

SD-WAN solutions use Forwarding Profiles (sometimes called traffic policies or path selection rules) to control how traffic is routed across available WAN links. A key feature of these profiles is the load balancing algorithm, which determines how outbound traffic is distributed. The default setting in most SD-WAN platforms (including Versa, Cisco Viptela, Fortinet, and others) is typically Per Flow.

The Per Flow algorithm assigns each individual session—defined by a unique combination of source/destination IP, port, and protocol—to a specific path. Once assigned, all packets from that flow continue on the same path until the flow ends. This ensures packet order consistency, making it highly suitable for latency-sensitive applications like VoIP and video conferencing. This method also avoids packet reordering issues that can occur with per-packet distribution.

Let’s consider the other choices:

• A. High Available Bandwidth – This method chooses the path with the most real-time available bandwidth. It’s ideal for throughput optimization but not commonly used as a default due to the extra overhead needed for continuous bandwidth evaluation.

• B. Per Packet – This technique splits packets from the same session across multiple paths, optimizing link utilization. However, it often leads to packet reordering, which degrades the performance of real-time applications. For this reason, it’s not typically used by default.

• C. Weighted Round Robin (WRR) – This approach assigns weights to each path and distributes traffic accordingly. While efficient for environments with links of unequal bandwidth, WRR is typically used in more customized scenarios, not as a default.

Conclusion:
Due to its balance of performance, stability, and low complexity, the Per Flow method is the default in most SD-WAN solutions. It ensures consistency in traffic behavior and is effective for a wide variety of applications without the downsides of packet reordering or computational overhead.

Question 5:

As a Versa Secure SD-WAN administrator, you are tasked with deploying a URL filtering policy across all customer-premises equipment (CPEs) in response to a recent cyber threat. 

Which template should be used to configure this security feature?

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

Correct Answer: C

Explanation:

In Versa Secure SD-WAN environments, administrators manage network behavior and security policies using modular templates. Each template serves a distinct purpose, whether it involves performance management, routing, or security enforcement. When you need to configure URL filtering, the Next-Generation Firewall (NexGen Firewall) Template is the proper mechanism.

URL filtering is an advanced security feature that enables administrators to block or allow access to websites based on categories, domains, or risk levels. This control is essential in modern enterprise networks to defend against phishing sites, malware distribution points, and non-compliant browsing behavior.

The NexGen Firewall Template (option C) in Versa is specifically designed to incorporate Layer 7 (application-layer) security functions, which include:

• URL filtering

• Intrusion prevention system (IPS)

• Application control

• Antivirus scanning

• SSL decryption and inspection

• Threat signatures

These advanced functions go beyond traditional firewalls by examining application content and behavior, rather than just IP addresses or ports.

Now, let’s briefly examine why the other options are incorrect:

• A. QoS Template: This is for managing Quality of Service, such as traffic shaping, prioritization, and bandwidth limits. It has nothing to do with content filtering or threat detection. URL filtering is unrelated to QoS objectives.

• B. Stateful Firewall Template: This supports basic Layer 4 rules, which control traffic based on source/destination IPs, ports, and protocols. It does not provide application awareness or URL-based filtering, which require Layer 7 inspection.

• D. Common Template: This is used for general configurations such as interfaces, routing, and services, and does not include security enforcement features. It is foundational but not applicable for URL filtering.

To respond effectively to a security event requiring URL filtering, the administrator must configure the URL filtering profile inside the NexGen Firewall Template, then apply this profile to the relevant security policy. This ensures consistent protection across all Versa CPEs.

Thus, the correct answer is C, the NexGen Firewall Template, which delivers the deep security capabilities needed for URL filtering.

Question 6:

A network engineer wants to view live traffic statistics on a specific Versa CPE interface. Which Versa platform component should be used to perform this task?

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

Correct Answer: B

Explanation:

To effectively manage a Versa Secure SD-WAN deployment, network operators require tools that provide real-time operational visibility. When a technician or administrator wants to monitor live interface statistics—such as link status, throughput, and packet loss—on a Versa CPE, the most suitable platform component is Versa Director (option B).

Versa Director acts as the centralized management and control plane interface for administrators. It provides capabilities for:

• Configuring and provisioning CPE devices

• Monitoring real-time operational health of interfaces and tunnels

• Viewing interface-level statistics like input/output rates, error counters, and interface status

• Executing diagnostics like ping and traceroute

This makes Director the primary tool for live operational monitoring, essential for diagnosing issues and validating performance.

Let’s analyze why the other options are less appropriate:

• A. Versa Controller: This platform component is focused on the control plane, such as overlay routing, policy distribution, and orchestrating SD-WAN tunnels. It does not provide an interface for viewing live statistics or monitoring data traffic in real time.

• C. Versa Analytics: While extremely valuable for trend analysis, historical reporting, and capacity planning, Analytics is not intended for live, per-interface monitoring. Data in Versa Analytics is telemetry-based and stored over time; it is ideal for reports and SLA tracking but unsuitable for real-time diagnostics.

• D. Versa CPE GUI: This offers local device-level access, often useful for on-site troubleshooting or limited configuration changes. However, it lacks the centralized, scalable capabilities required for efficiently managing multiple CPEs in large networks. It's not optimal for day-to-day operational monitoring.

Versa Director allows operators to view live metrics across all deployed devices from a single dashboard, supporting proactive operations, real-time troubleshooting, and interface validation.

For any task that involves live interface monitoring, Versa Director is the purpose-built tool, making B the correct answer.

Question 7:

Which two statements accurately describe Class of Service (CoS) functionalities within a Versa branch SD-WAN device? (Choose two)

A. Remarking differentiates traffic using Layer 3, Layer 4, and Layer 7 information.
B. Classification directly modifies CoS values in outbound traffic.
C. Queuing determines traffic priority and allocates bandwidth using weights.
D. Scheduling regulates the sequence in which packets are transmitted.

Correct Answers: C and D

Explanation:

In a Versa Secure SD-WAN deployment, Class of Service (CoS) is essential for managing how various types of traffic are handled, ensuring critical applications receive the appropriate network resources. The CoS model in Versa typically includes several stages: classification, remarking, queuing, and scheduling.

Let’s evaluate the given options to identify the two correct descriptions:

• A. Remarking differentiates traffic using Layer 3, Layer 4, and Layer 7 information:
  This is incorrect. Remarking is the process of re-tagging packets by modifying fields such as DSCP, IP precedence, or MPLS EXP bits to reflect their assigned priority. However, it does not classify traffic using L3-L7 details. Instead, remarking occurs after classification and simply updates the packet’s CoS markings for downstream handling.

• B. Classification directly modifies CoS values in outbound traffic:
  This is misleading. Classification is responsible for identifying and tagging traffic based on its attributes—like IP addresses, ports, or application type (L3-L7). However, it does not itself alter CoS fields; that role belongs to remarking. Classification only assigns the traffic to classes or queues, making this statement incorrect.

• C. Queuing determines traffic priority and allocates bandwidth using weights:
  This is accurate. Queuing involves placing traffic into different queues based on their class. Each queue can be assigned a priority level and weight, allowing the SD-WAN device to ensure high-priority traffic like VoIP or video is processed preferentially. Weighted queuing methods (like WRR or WFQ) ensure bandwidth fairness across different service classes.

• D. Scheduling regulates the sequence in which packets are transmitted:
  This is also correct. Once traffic is placed into queues, scheduling determines how packets from these queues are selected for transmission. Scheduling algorithms like Strict Priority (SP), Round Robin (RR), or Weighted Fair Queuing (WFQ) decide the order and rate of packet forwarding, ensuring latency-sensitive traffic is delivered promptly.

In Versa SD-WAN, CoS functionalities include multiple mechanisms for traffic handling. Queuing controls how much bandwidth and priority is given to traffic classes, while scheduling decides the order in which queued packets are sent. Hence, the correct answers are C and D.

Question 8:

Which two statements correctly describe the live monitoring features available for Versa CPEs in a Versa SD-WAN setup? (Choose two)

A. Versa Analytics enables real-time monitoring of all services running on CPEs.
B. Versa Director provides full real-time monitoring across all CPE services.
C. Versa Analytics includes ping, traceroute, tcpdump, and speed test tools.
D. Versa Director provides built-in diagnostic tools like ping and traceroute.

Correct Answers: A and D

Explanation:

In a Versa SD-WAN deployment, both Versa Analytics and Versa Director play important but distinct roles in monitoring and managing Customer Premises Equipment (CPE) devices.

Let’s analyze each component’s capabilities to identify the correct statements:

• A. Versa Analytics enables real-time monitoring of all services running on CPEs:
  This is correct. Versa Analytics is designed as a data visualization and telemetry platform. It provides real-time and historical monitoring of key metrics such as interface stats, application traffic patterns, link performance (latency, jitter, loss), and security events. Dashboards and reports generated by Analytics offer deep insights into network behavior, making it essential for performance monitoring and SLA validation.

• B. Versa Director provides full real-time monitoring across all CPE services:
  This is only partially accurate and is therefore incorrect. Versa Director is primarily a management and orchestration tool, responsible for pushing configurations, managing policies, and performing diagnostics. While it does offer some basic monitoring, it does not provide full-spectrum real-time telemetry or visual analytics—those functions belong to Versa Analytics.

• C. Versa Analytics includes ping, traceroute, tcpdump, and speed test tools:
  This is incorrect. While Versa Analytics is excellent for passive data collection and visualization, it does not offer active network testing or troubleshooting tools like ping or tcpdump. Those tools are integrated into Versa Director for operational diagnostics.

• D. Versa Director provides built-in diagnostic tools like ping and traceroute:
  This is correct. Versa Director includes a suite of diagnostic tools (ping, traceroute, tcpdump, speed test) that administrators can run directly on remote CPE devices. These tools are invaluable for live troubleshooting and confirming network connectivity issues during incidents.
  Versa Analytics is used for real-time service monitoring and visualization, while Versa Director is the go-to tool for executing live diagnostics using embedded tools. Thus, the correct answers are A and D.

Question 9:

Which component in the Versa Secure SD-WAN architecture is responsible for centralized configuration, control, and analytics?

A. Versa FlexVNF
B. Versa Analytics
C. Versa Director
D. Versa Controller

Correct Answer: C

Explanation:

In Versa Secure SD-WAN, the solution is built on a modular architecture that includes the FlexVNF, Versa Director, Versa Analytics, and sometimes Controllers. Each component plays a distinct role in enabling a scalable, secure, and agile wide area network.

The Versa Director serves as the centralized management and orchestration platform. It provides a web-based GUI and RESTful APIs to manage the entire SD-WAN fabric. From this single pane of glass, administrators can:

• Configure policies and services across branches

• Push templates to FlexVNF instances

• Perform software upgrades

• Manage certificates

• Monitor alarms and event logs

It acts as the primary control point for administrators and simplifies day-to-day network operations.

• A. Versa FlexVNF is the data plane element and performs packet forwarding, routing, security, and other edge functions. It is installed at branch or hub sites.

• B. Versa Analytics is responsible for collecting, storing, and visualizing telemetry such as traffic stats, application usage, and system health metrics. While it offers great visibility, it does not configure or orchestrate services.

• C. Versa Director (Correct) manages centralized configuration, policy templates, device management, and integrates with Versa Analytics for visibility.

• D. Versa Controller can provide route reflection and help in building dynamic overlays, but it's not the centralized orchestration point.

In summary, Versa Director plays the central role in managing, configuring, and controlling SD-WAN elements across the fabric. This makes it the correct answer for identifying the central orchestration component in the Versa SD-WAN architecture.

Question 10:

Which method is commonly used to establish secure overlay tunnels between branch locations in Versa Secure SD-WAN?

A. GRE tunnels with static routes
B. IPSec tunnels orchestrated by Versa Director
C. OpenVPN tunnels using FlexVNF CLI
D. VXLAN tunnels managed by Versa Analytics

Correct Answer: B

Explanation:

One of the core capabilities of Versa Secure SD-WAN is the ability to create secure overlay tunnels across any transport network (MPLS, broadband, LTE). These tunnels provide encrypted communication and logical segmentation between sites in a hub-and-spoke, full-mesh, or hybrid topology.

The most commonly used method for creating these tunnels is IPSec, and Versa automates the tunnel creation process using its SD-WAN controller logic. Here's how it works:

• The administrator defines overlay topology and security settings in Versa Director.

• The system automatically generates IPSec tunnel configurations between the FlexVNF instances at each site.

• These tunnels are encrypted and can be dynamically adapted to routing or policy changes.

• A. GRE tunnels with static routes are not secure and are manually configured. Versa supports GRE, but IPSec is the default and preferred option due to encryption.

• B. IPSec tunnels orchestrated by Versa Director (Correct) provide encryption, authentication, and policy-based routing while being centrally managed.

• C. OpenVPN tunnels using CLI are not used in Versa’s enterprise SD-WAN deployments and offer limited scalability and manageability.

• D. VXLAN is used for network virtualization at Layer 2 and is not typically used as a secure site-to-site overlay method in Versa SD-WAN.

IPSec offers the benefits of encryption, integrity, and confidentiality, and Versa simplifies its deployment through centralized policies, automation, and dynamic negotiation. Because of this, Option B is the most accurate and secure method for connecting SD-WAN sites.
