To apply a new URL filtering profile across all of the SD-WAN CPEs in response to a security event, you would use the Next Generation Firewall (NGFW) Template. This template is specifically designed to handle security functions, including application control, intrusionprevention, and URL filtering. By using the NGFW Template, you can enforce URL filtering policies that block or allow traffic based on URLs and categories, which is integral to controlling access to websites and ensuring network security​​.

The default load balancing algorithm set in an SD-WAN Forwarding Profile is Weighted Round Robin (WRR). This algorithm assigns weights to each path based on the available bandwidth on the access circuit. WRR is recommended when paths with equal priorities are provisioned with different bandwidths, ensuring that traffic is distributed proportionally to the bandwidth of each path, which optimizes the utilization of network resources and maintains load balancing across the WAN circuits​​.

Versa Secure Access (VSA) is designed to integrate with various authentication servers, including LDAP, and supports multifactor authentication methods like email and time-based OTP, integrating with authentication applications such as Duo, Google Authenticator, and Microsoft Authenticator. This makes the platform versatile in terms of supporting different enterpriserequirements for user authentication and enhancing security.​

When a speed test fails, it could be due to the speed test module not being activated or the speed test server not being enabled at the remote site. If the speed test module has not been activated, the required functionality to conduct the test will not be operational. Similarly, if the remote site does not have the speed test server enabled, it won't respond to speed test requests. Issues with the SLA path status or client configuration might be relevant to the performance and reachability but are not cited as direct reasons for a speed test failure within the documentation provided.

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.

To configure an SD-WAN branch so that Internet-bound traffic uses the local Internet link, the Service Chain Template is used. This template is part of the Director Workflows and allows the local breakout of internet traffic directly from the branch, bypassing the central or regional breakout points. This is an essential component of the Versa Secure SD-WAN design, where traffic intended for the internet can be directed through the most efficient route, often through a local Internet link at the branch site, instead of being backhauled to a central location.​

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 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.

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​​.

When a Versa CPE security policy rule is configured to generate and send logging information on policy hits using the Default Logging Profile, Versa Analytics is the component that would allow you to view these logs. Versa Analytics provides extensive visibility into network traffic and security events, which includes logging information from security policies in action.​

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.

When a customer has a single Versa Analytics cluster deployed in a data center with the Versa Director and Versa Controller nodes distributed between the data center and disaster recovery sites, and the data center goes down for one day, logging and reporting will be lost during the one-day downtime (D). Versa Analytics plays a crucial role in collecting, processing, and presenting data for monitoring and reporting purposes. Its deployment in a single data center without active redundancy means that its failure or unavailability directly impacts the network's ability to perform logging and generate reports. However, the SD-WAN CPE live monitoring (A), the deployment of new SD-WAN CPE (B), and the reachability between SD-WAN CPE (C) could still be maintained through the remaining operational elements of the SD-WAN architecture, assuming that the Versa Director and Versa Controller can still manage the network despite the loss of analytics capabilities​​.

In the event of a network outage, to verify the live status of the WAN links, Versa Director device monitoring dashboard and Versa Analytics sites availability dashboard are the tools to use.These components provide real-time visibility into the status and health of WAN links, allowing for rapid identification and troubleshooting of connectivity issues.​

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.​

In SD-WAN policy rules, two parts used to steer traffic are Schedules and Applications. Schedules allow administrators to define when certain policy rules should be active, effectively determining the timing for when traffic steering decisions should be applied. Applications, on the other hand, enable traffic steering decisions based on the type of application traffic being detected. This allows for more granular control and optimization of traffic flows based on application requirements and characteristics​​.
