Pass the Versa Networks Administrator SD-WAN Associate VNX100 Questions and answers with ExamsMirror

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.

An SD-WAN Forwarding Profile is a set of rules that determine how outgoing traffic should be handled within the SD-WAN network. It particularly defines which WAN links should be selected for forwarding the traffic based on certain criteria such as link performance, priority, and SLA compliance. The Forwarding Profile ensures that traffic is directed over the most appropriate link, which may involve decisions based on the link's performance metrics like latency, jitter, or packet loss, ensuring efficient and optimal use of the WAN infrastructure​​.

In a Versa Secure SD-WAN deployment, the following statements about traffic forwarding are accurate:

By default, all data traffic is forwarded on IPSec tunnels (Answer A): Versa SD-WAN solutions typically encrypt all data traffic by default using IPSec tunnels. This security measure ensures that data remains protected while transiting over the public or private WAN, safeguarding against eavesdropping and data theft.

By default, all control traffic is forwarded on IPSec tunnels (Answer B): Similarly, control traffic in Versa SD-WAN is also encrypted and sent through IPSec tunnels. This practice secures the signaling and management traffic, preventing potential attacks that could target the network’s control plane.

Options C (By default, all data traffic is forwarded on unencrypted tunnels) and D (By default, all control traffic is forwarded on unencrypted tunnels) are incorrect as they contradict the security-oriented design of Versa SD-WAN, which emphasizes the encryption of both data and control traffic by default.

References:This explanation utilizes Versa SD-WAN's documented security features and general network security protocols that prioritize encrypted communications for both data and control planes.

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 Director provides real-time monitoring capabilities for all services running in Versa CPE. It offers visibility into the live status, performance, and health of the services, which is crucial for proactive management and rapid troubleshooting of any issues that may arise in the network. This capability enables network administrators to closely monitor the functioning of various services within the CPE and take immediate action if any anomalies are detected​​.

C. Versa Analytics has built-in ping, traceroute, tcpdump, and speed test tools.Versa Analytics is equipped with built-in tools such as ping, traceroute, tcpdump, and speed test capabilities. These tools are essential for diagnosing and resolving network issues. They enable network operators to test connectivity, trace the path of packets across the network, capture traffic for analysis, and measure the bandwidth of network connections. Having these tools integrated within Versa Analytics simplifies the process of network diagnostics and ensures that network operators can efficiently manage and optimize network performance​​​​.

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.

By default, when configuring Direct Internet Access (DIA) through workflows, the protocol that runs between the tenant virtual router (VRF) and the transport WAN Virtual Router (VR), connected by the TVI interfaces, is EBGP (External Border Gateway Protocol). This protocol is used to control route distribution and is a fundamental part of the VOS Edge Device DIA Architecture. In such a configuration, the tenant VRF uses EBGP to advertise the default route, which is resolved using the logical tunnel created for DIA​​.

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.​
