Versa Networks VNX100 Dumps Questions Answers

The provisioning of Versa SD-WAN CPE devices can be accomplished through multiple methods, including:

• URL-based provisioning (Answer B): This method involves directing the CPE to a URL where it can download configuration files automatically. This is an efficient way to provision devices remotely and is widely used for initial device setup and configuration.
• Script-based provisioning (Answer C): This method allows network administrators to use scripts to automate the configuration process of CPEs. Scripts can be customized to apply specific configurations and policies based on the deployment requirements.

References:Both URL-based and script-based provisioning are standard practices detailed in Versa's deployment guides, which provide step-by-step instructions on using these methods for efficient and scalable CPE deployments.

In a scenario where a device is onboarded with two Internet interfaces and Direct Internet Access (DIA) is being configured, the following statements hold true:

• Each underlay interface belongs to its own VR instance (Answer B): Typically, in Versa SD-WAN configurations, each underlay interface is assigned to its own virtual router (VR) instance. This approach allows for greater flexibility and isolation in managing routing and security policies specific to each interface. It supports independent operation and control, which is crucial for optimizing performance and security management.
• Both Internet interfaces can be selected for DIA in workflows (Answer C): In Versa workflows, it is possible to configure both Internet interfaces for DIA. This configuration enhances redundancy and ensures that there is always an active path for Internet access, which is critical for maintaining high availability and network resilience.

The option A (All underlay interfaces belong to the same VR instance) is not typically true in complex deployments where separation of control and data planes is required for better management and security. Option D (Only one Internet interface can be selected for DIA in workflows) is incorrect because Versa SD-WAN allows multiple interfaces to be configured for DIA to leverage failover and load-balancing capabilities.

References:This explanation is based on the standard practices of deploying Versa SD-WAN solutions, where the architecture supports multiple virtual routers and the capability to configure multiple interfaces for DIA.

The Direct Internet Access (DIA) option in the configuration of split tunnels for an SD-WAN device, as shown in the exhibit, is a feature that allows traffic destined for the internet to bypass the SD-WAN overlay network and be sent directly out of the local branch’s internet connection. This can significantly improve access to cloud services andinternet performance by reducing latency and avoiding backhauling traffic through the corporate data center or another central location.

When DIA is enabled, traffic that is destined for the internet does not traverse the SD-WAN overlay network; instead, it is routed directly from the branch to the internet. The SD-WAN appliance can still enforce security policies on this traffic, and it can also be programmed to dynamically decide whether to use the DIA path based on real-time performance metrics and other criteria.

By implementing the BGP default route advertisement into the local LAN Virtual Routing and Forwarding (VRF) of the tenant, the SD-WAN appliance advertises a default route to the local site. This allows the site to route internet-bound traffic directly to the internet without having to send it across the SD-WAN network. This eases the internal network traffic load and can potentially reduce costs associated with data transmission over the corporate WAN.

References:The explanation provided above aligns with standard SD-WAN architecture and practices for configuring split tunnels and the use of Direct Internet Access in SD-WAN environments.
