VNX100 Versa Networks Versa Certified SD-WAN Associate Free Practice Exam Questions (2025 Updated)

In a Versa Analytics cluster, the node personalities include Search and Analytics. These personalities reflect the different roles each node in the cluster plays. The Search nodes are responsible for ingesting and indexing data, enabling fast and efficient search operations, while the Analytics nodes are responsible for processing and analyzing data, providing insights and reports. This separation of duties is key to the operation of a Versa Analytics cluster, ensuring optimal performance and reliability of the analytics platform.

When a customer has a single Versa Analytics cluster deployed in a data center with the Versa Director and Versa Controller nodes distributed between the data center and disaster recovery sites, and the data center goes down for one day, logging and reporting will be lost during the one-day downtime (D). Versa Analytics plays a crucial role in collecting, processing, and presenting data for monitoring and reporting purposes. Its deployment in a single data center without active redundancy means that its failure or unavailability directly impacts the network's ability to perform logging and generate reports. However, the SD-WAN CPE live monitoring (A), the deployment of new SD-WAN CPE (B), and the reachability between SD-WAN CPE (C) could still be maintained through the remaining operational elements of the SD-WAN architecture, assuming that the Versa Director and Versa Controller can still manage the network despite the loss of analytics capabilities​​.

To apply a new URL filtering profile across all of the SD-WAN CPEs in response to a security event, you would use the Next Generation Firewall (NGFW) Template. This template is specifically designed to handle security functions, including application control, intrusionprevention, and URL filtering. By using the NGFW Template, you can enforce URL filtering policies that block or allow traffic based on URLs and categories, which is integral to controlling access to websites and ensuring network security​​.

Versa Secure SD-WAN features multitenancy, allowing multiple tenants to be managed within the same infrastructure with complete isolation and privacy. Additionally, it offers Role-Based Access Control (RBAC) to define and limit the permissions and access for users based on their roles within the organization. Versa also provides single-pane-of-glass management with embedded analytics, offering a consolidated view for managing, monitoring, and analyzing the SD-WAN infrastructure and traffic. This unified management approach simplifies administrative tasks and provides deep insights into the network and security operations.

To configure an SD-WAN branch so that Internet-bound traffic uses the local Internet link, the Service Chain Template is used. This template is part of the Director Workflows and allows the local breakout of internet traffic directly from the branch, bypassing the central or regional breakout points. This is an essential component of the Versa Secure SD-WAN design, where traffic intended for the internet can be directed through the most efficient route, often through a local Internet link at the branch site, instead of being backhauled to a central location.​

URL-based Zero-Touch Provisioning (ZTP) is an approach where the URL of a Versa Operating System activation website is emailed to the installer at the customer site. The installer then connects a laptop to the Wi-Fi or LAN port of the Versa branch device, clicks on the URL, and completes the provisioning process. This method does not require a console connection and is one of the methods provided by Versa to provision and configure new VOS devices, making the process convenient and straightforward.​

The diagram in the exhibit illustrates a hub and spoke topology where the spokes connect through a central hub. This is evident from the dashed lines that show the data flow between the spokes is mediated by the hub (Hub1). In this topology, while the spokes may have direct connections, the data flows between them pass through the hub. This kind of topology is commonly used in SD-WAN deployments to simplify routing and policy enforcement, which are managed centrally at the hub, as opposed to setting up direct paths between all spoke sites, which would be indicative of a full mesh or spoke-to-spoke direct topology.

In the context of Versa SD-WAN, Class of Service (CoS) refers to mechanisms within the network that manage traffic prioritization and resource allocation. CoS is essential for ensuring that critical business applications receive the necessary bandwidth and low-latency treatment they require to function effectively.

A.Remarking: Remarking is a process that manipulates the Class of Service bits (in the IP header's DSCP field) or Layer 2 CoS fields (in the VLAN tag's priority code point - PCP). By remarking these fields based on Layer 3 (IP), Layer 4 (TCP/UDP ports), and Layer 7 (application identification) details, the network can differentiate and prioritize traffic. This ensures that critical applications, such as voice and video, are given higher priority over less time-sensitive data.

C.Queuing: Queuing mechanisms within Versa SD-WAN determine how packets are treated as they are processed through the network. Various queues can be assigned different priorities and weights to control the order in which packets are sent out through the network interface. High-priority queues might be reserved for voice traffic to reduce latency, while lower-priority queues could be used for bulk data transfers that are less sensitive to delays.

When a speed test fails, it could be due to the speed test module not being activated or the speed test server not being enabled at the remote site. If the speed test module has not been activated, the required functionality to conduct the test will not be operational. Similarly, if the remote site does not have the speed test server enabled, it won't respond to speed test requests. Issues with the SLA path status or client configuration might be relevant to the performance and reachability but are not cited as direct reasons for a speed test failure within the documentation provided.

Versa CPEs support a variety of Quality of Service (QoS) functions to ensure effective bandwidth management and priority handling of network traffic. The three functions supported are:

Hierarchical queuing (Answer B): This QoS function allows for the creation of a multi-level queue structure, enabling more granular control of traffic prioritization and bandwidth allocation among various traffic classes.

Egress policing (Answer C): This involves setting maximum bandwidth limits for outbound traffic on network interfaces to prevent any traffic class from consuming excessive bandwidth and impacting the performance of other critical applications.

Classification (Answer D): This is the process of marking packets based on predefined criteria, which can include source or destination IP addresses, ports, or application types. Classification is essential for applying the appropriate QoS policies to different types of traffic.

References:These functionalities are extensively described in Versa’s configuration manuals, where the setup and implications of each QoS feature are discussed, ensuring optimal network performance and adherence to organizational policies.

Service templates are used to apply an identical QoS configuration to multiple CPEs, ensuring consistent quality of service across the network. Additionally, these templates are also employed to share an identical service configuration across different tenants within a multi-tenant architecture, ensuring uniform policy application while maintaining tenant separation.

A Versa Workflow is a process within Versa Director that automates the creation or modification of objects, such as device templates, policies, and service profiles. Workflows streamline complex configurations, guiding administrators through a series of steps to configure devices, apply policies, and set up services across the SD-WAN infrastructure. It simplifies and accelerates the deployment and management of the SD-WAN solution.

When a Versa CPE security policy rule is configured to generate and send logging information on policy hits using the Default Logging Profile, Versa Analytics is the component that would allow you to view these logs. Versa Analytics provides extensive visibility into network traffic and security events, which includes logging information from security policies in action.​

To identify and diagnose intermittent network performance issues that occurred in the past,Versa Analytics dashboards (Answer B)are the most suitable component. Versa Analytics provides deep insights into historical data, enabling network administrators to analyze trends, performance metrics, and potential bottlenecks that occurred previously. The dashboards offer a comprehensive view of the network's operational performance over time, allowing for effective troubleshooting of issues that are not currently manifesting but did impact users in the past.

References:Versa Analytics dashboards are specifically designed to handle retrospective and real-time network data analysis, making them an essential tool for diagnosing past issues as described in Versa's official documentation on network analytics and performance monitoring.

Within the Device Template workflow, you can configure various settings that dictate how the SD-WAN devices will behave in the network. While specific port numbers like WAN/LAN ports and serial numbers are usually predefined hardware attributes and not set via templates, Device Group classification and Direct Internet Access configurations are part of the template workflow. Device Groups help in classifying devices for easier management, and Direct Internet Access (DIA) settings determine how internet traffic will be handled, allowing for traffic to bypass central gateways and go directly to the internet, which can be crucial for optimizing the network performance.

If the console cable is missing during the unboxing of an SD-WAN CPE for script-based provisioning, the engineer can initiate the provisioning process by connecting a laptop to the management port on the device. The management port provides a direct interface for configuration tasks, allowing the engineer to access the device's command-line interface without the need for the standard console connection.​

Versa Director acts as an orchestrator within the Versa SD-WAN ecosystem, providing centralized configuration management and monitoring of controllers, branch sites, and hubsites. It does not function as a log forwarder, BGP route reflector, or VPN concentrator. As an orchestrator, it manages the lifecycle of Versa VOS instances, enabling zero-touch provisioning and other orchestration functionalities through a single pane of glass.
