Versa Networks VNX100 - Versa Certified SD-WAN Associate

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 a Versa Analytics cluster, the node personalities include Search and Analytics. These personalities reflect the different roles each node in the cluster plays. The Search nodes are responsible for ingesting and indexing data, enabling fast and efficient search operations, while the Analytics nodes are responsible for processing and analyzing data, providing insights and reports. This separation of duties is key to the operation of a Versa Analytics cluster, ensuring optimal performance and reliability of the analytics platform.

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​​.

Versa Analytics and Versa Director support REST APIs, which allow integration with third-party applications and systems. The REST APIs provided by these components enable automation and programmability for various network management and analytics functions. Versa Controller and Versa CPE are not referenced in the provided documents as supporting REST APIs directly, although they interact with Versa Director, which does.​

Versa Analytics, part of the Versa SD-WAN solution, can be deployed on-premises and is not limited to cloud-based installations. This gives enterprises the flexibility to choose where to deploy based on their specific needs, such as compliance or data sovereignty requirements. The Versa Controller, which provides the control plane for the SD-WAN network, supports various deployment options including virtual machines. This flexibility is important for integration into existing data center architectures or for leveraging cloud infrastructures.

In a remote Versa branch, the Control Virtual Router (Control VR) is the routing instance that has the default route to reach the Versa head-end components. This Control VR is typically dedicated to carrying control plane traffic between branch nodes and the SD-WAN controller, facilitating secure communications essential for the management and operation of the SD-WAN network.

Within the Device Template workflow, you can configure various settings that dictate how the SD-WAN devices will behave in the network. While specific port numbers like WAN/LAN ports and serial numbers are usually predefined hardware attributes and not set via templates, Device Group classification and Direct Internet Access configurations are part of the template workflow. Device Groups help in classifying devices for easier management, and Direct Internet Access (DIA) settings determine how internet traffic will be handled, allowing for traffic to bypass central gateways and go directly to the internet, which can be crucial for optimizing the network performance.

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.

In a Post-staging Template within the Versa SD-WAN solution, device-specific information such as WAN IP addresses, LAN subnets, and route ID are collectively referred to as "Bind Data". This term is used to describe the information that is specific to individual devices, which must be entered to tailor the general staging template to the unique requirements of each device during the staging process.
