VNX100 Exam Dumps - Versa Networks Administrator SD-WAN Associate Questions and Answers

Versa Analytics has the capability to not only generate customized daily reports on bandwidth usage for all sites in the network but also to schedule these reports to be sent via email. This function allows administrators to receive reports without having to log into the Versa Analytics portal, streamlining the process and ensuring that they have the necessary information on a regular basis​​.

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.

Versa CPEs are indeed activated using Zero Touch Provisioning (ZTP), which automates the configuration process and reduces operational complexity. Furthermore, all components of the Versa SD-WAN solution support high availability configurations to ensure continuous operation and minimal disruption in the event of component failures. Versa Director and Versa Controllers can be deployed in redundant configurations, and Versa Analytics can be clustered for resilience and high availability.

To monitor a Versa CPE interface's live data, you would use the Versa Director. The Versa Director provides a comprehensive interface for real-time monitoring and management of SD-WAN infrastructure, including the visualization of traffic flows and performance metrics. Through Versa Director, network operators can gain insights into transmission data for all traffic or SD-WAN-specific traffic, updated every few seconds, and detailed information about interface statistics​​.

The Versa Operating System (VOSTM) is the software platform that provides routing, advanced SD-WAN, and SD-Security in a single software package. The VOS software is deployed in the branch, hub, cloud, and data center. Specifically, it is utilized within the Versa Controller, the Versa SD-WAN CPE, and the Versa SD-WAN Gateway, which are the components that use VOS to deliver their networking and security functions. Versa Director, on the other hand, is a centralized provisioning and management application that manages the VOS software instances but does not run the VOS itself. Versa Analytics is an analytics engine that provides insights into network traffic and events and also does not run the VOS itself.​

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 security pack (SPack) within Versa VOS includes predefined objects such as anti-virus definitions, URL categories and reputations, and IDS/IPS signature definitions. These are components of Versa VOS's unified threat management capabilities, which are utilized toprotect the network against security threats. Operating system security updates and Versa Analytics security updates are not mentioned as part of the SPack predefined objects in the provided documents.

The policy shown in the exhibit appears to match traffic flows based on multiple conditions involving the source zone and the application. Given the information in the screenshot:

• The policy is configured with multiple zones as source zones:Intf-LAN1-ZoneandIntf-WLAN-Zone.
• An application is specified:SHAREPOINT.

The policy is likely to be applied to traffic originating from either of the specified zones and specifically related to the SharePoint application. This implies that both conditions related to the source zones are not mutually exclusive but rather a union; the same goes for the application condition.

Given this interpretation, the correct set of conditions that match the policy shown would be:

B.Traffic flows that meet any of the following two conditions:

• Source Zone - Intf-LAN1 Zone
• Source Zone - Intf-WLAN-Zone

In addition, the below condition must also match:

• Application - SharePoint

This means that traffic will match the policy if it comes from either theIntf-LAN1-Zoneor theIntf-WLAN-Zoneandis SharePoint application traffic.

However, to be more precise in the context of Versa SD-WAN configurations, it's important to note that policies are usually applied when all conditions within a single rule are met. If the configuration in the screenshot intends to express that traffic is matched if it comes from either of the two zones and is for the SharePoint application, then the correct answer should reflect this logic. If the configuration system is set up to require all conditions in a rule to be met, then the answer could potentially be different. Since the user interface design can sometimes vary, it’s important to understand the specific logic of the system in question.

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.

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.
