The Versa Stateful Firewall feature encompasses a range of security capabilities, including Unified Threat Management (UTM), which may comprise antivirus, IPS, and web filtering services. It also provides Zone Protection, which enforces security policies based on the zones defined in the network to protect network segments. DDoS protection and DUP are also vital security functions, but they are not specified as capabilities within the Stateful Firewall feature set in the documents provided.

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.​

The Versa Secure SD-WAN Head-end consists of the Versa Controller, Versa Director, and Versa Analytics. However, when referring to headend nodes as components, the Versa Director and Versa Analytics are part of it. The Versa Controller, while an integral part of the SD-WAN control plane, is not listed under 'Headend Node' in the provided documentation. The Versa Director and Versa Analytics work in conjunction to manage a network of VOS devices, with the Director being the provisioning and management application and Analytics providing the analytics engine. Versa Gateway is not mentioned as part of the head-end components in the context provided.​

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.

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​​.

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​​.

When changes to a device configuration are made in the Versa Director through templates, it is crucial to ensure that these changes propagate to the actual branch device. The correct steps involve:

Committing the Device Template configuration to the appliance (Answer B): This step is necessary because any changes made in the device template need to be actively committed to ensure they are pushed to the specific branch device orappliances that are associated with this template. This action updates the appliance with the latest configuration details, including the static IP address changes for the WAN link.

Updating the Device Bind Data in Workflows with the IP address and gateway of the Internet WAN link (Answer D): This involves updating the binding configurations that specifically tie device templates to actual hardware or site-specific configurations. It is essential when changes such as IP addressing are involved, as the binding data must accurately reflect the network topology and addressing used by the devices.

References:The detailed steps and necessity for these actions are derived from standard Versa SD-WAN configuration practices as reflected in the comprehensive Versa configuration manuals and best practices documents available through Versa Networks Academy Library and configuration guides.

The roles of a Versa Controller include onboarding SD-WAN VOS branches into the network and maintaining a secure control channel with each node. The Versa Controller authenticates branch VOS instances, handles management activities between the remote and headend nodes, and distributes control plane information. It does not provide Internet breakout, which is a function typically performed by edge devices at the branches themselves, nor does it provide clock synchronization to the branches, which is generally a function of network protocols like NTP that operate independently of SD-WAN control.​

To require users to justify their access to specific types of websites, such as social media sites, theCaptive Portal (Answer D)feature is used. This feature intercepts users' web requests, redirecting them to a portal where they must authenticate or provide justification for accessing the requested site. It is particularly useful in enforcing corporate policies and ensuring that access to certain types of sites is for legitimate business purposes.

References:The use of captive portals for controlling and monitoring access to web resources is a common practice in network administration, as outlined in Versa's configuration guidelines for secure network access and user authentication protocols.
