VNX100 Exam Dumps : Versa Certified SD-WAN Associate

In the architecture of Versa SD-WAN, the control plane plays a crucial role in the discovery and management of network topology:

• SD-WAN topology is discovered using MP-iBGP (Answer B): Versa utilizes Multi-Protocol Interior Border Gateway Protocol (MP-iBGP) for the discovery and management of the SD-WAN topology. This protocol helps in the efficient exchange of routing information within the network, enabling the Versa Director and other network components to maintain an updated view of network topology.
• Versa Private Address Family is used to advertise topology information (Answer C): This unique address family within Versa’s ecosystem is specifically designed to handle and distribute topology information across the network. It ensures that all relevant Versa devices are aware of the network structure and any changes to it.

References:These elements of Versa’s SD-WAN control plane are detailed in the technical specifications and white papers provided by Versa Networks, which explain the underlying mechanisms that support network operations and topology management within Versa’s infrastructure.

Versa Analytics offers REST APIs that facilitate northbound integration with third-party tools, allowing for enhanced automation and the ability to pull data into external systems for additional processing or visualization. Moreover, it provides real-time traffic monitoringdashboards that deliver visibility into network performance, application usage, and security events, aiding in swift and informed decision-making. These dashboards are crucial for maintaining an overview of the network's current state and rapidly diagnosing issues.​

Versa Analytics offers a suite of features aimed at enhancing visibility and control over SD-WAN networks. The true statements about Versa Analytics are:

• Versa Analytics provides REST APIs for northbound integration with third-party tools (Answer B): Versa Analytics is equipped with REST APIs that facilitate northbound integration, allowing organizations to seamlessly connect and integrate Versa's network data with third-party management, monitoring, and analytics tools. This integration capability is crucial for enterprises that utilize a diverse set of tools for network management and need to consolidate their network operations on a single platform.
• Versa Analytics provides real-time traffic monitoring dashboards (Answer D): One of the key features of Versa Analytics is its real-time traffic monitoring dashboards. These dashboards provide network administrators with live insights into network performance, traffic flows, and usage patterns, enabling them to make informed decisions quickly and effectively manage the network.

Option A (Versa Analytics provides the ability to configure logging parameters on SD-WAN CPEs) is incorrect because while Versa Analytics does involve extensive logging capabilities, the configuration of logging parameters typically occurs at the device or controller level, not within the analytics platform itself. Option C (Versa Analytics provides centralized logging information about the SD-WAN environment) is somewhat misleading; while Versa Analytics does centralize data for analysis, it primarily focuses on providing analytical insights and data visualizations rather than merely centralizing logging information.

References:This explanation is based on the functionalities provided by Versa Analytics as part of the Versa SD-WAN solution, emphasizing its capabilities in network data integration and real-time monitoring.

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.
