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.

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.​

In a Versa Secure SD-WAN solution, the hub controller plays a multifaceted role that is crucial for the efficient and secure operation of the network. Three of the primary functions of a hub controller include CPE lifecycle management, acting as a control plane node, and providing visibility and control.

CPE Lifecycle Management (A): The hub controller is instrumental in managing the lifecycle of Customer Premises Equipment (CPE). This includes tasks such as configuration, maintenance, updates, and troubleshooting. This management capability ensures that the CPEs are always operating with the latest security patches, configurations, and software versions, thereby maintaining the security and efficiency of the network.

Control Plane Node (B): The hub controller also serves as a control plane node. It is responsible for maintaining the routing information and ensuring the efficient distribution of this information across the network. This includes handling BGP routes toward VPNsand tenants, distributing security association (SA) information, and enabling IPsec connectivity between branches without the overhead of maintaining a full mesh of IKE keys among all branches​​.

Visibility and Control (D): Finally, the hub controller provides visibility and control over the network. This includes monitoring the network's health, traffic management, and implementing security policies. By offering a centralized point of visibility and control, the hub controller enables network administrators to effectively manage and secure the network.

The hub controller's role as a data plane node (C) is not explicitly mentioned among its primary functions, as it is more involved in the control and management aspects of the network rather than direct data forwarding. Similarly, acting as a staging server (E) is not listed as one of its primary roles in the documentation reviewed.

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.​

To identify and diagnose intermittent network performance issues that occurred in the past,Versa Analytics dashboards (Answer B)are the most suitable component. Versa Analytics provides deep insights into historical data, enabling network administrators to analyze trends, performance metrics, and potential bottlenecks that occurred previously. The dashboards offer a comprehensive view of the network's operational performance over time, allowing for effective troubleshooting of issues that are not currently manifesting but did impact users in the past.

References:Versa Analytics dashboards are specifically designed to handle retrospective and real-time network data analysis, making them an essential tool for diagnosing past issues as described in Versa's official documentation on network analytics and performance monitoring.

URL-based Zero-Touch Provisioning (ZTP) is an approach where the URL of a Versa Operating System activation website is emailed to the installer at the customer site. The installer then connects a laptop to the Wi-Fi or LAN port of the Versa branch device, clicks on the URL, and completes the provisioning process. This method does not require a console connection and is one of the methods provided by Versa to provision and configure new VOS devices, making the process convenient and straightforward.​

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 Director acts as an orchestrator within the Versa SD-WAN ecosystem, providing centralized configuration management and monitoring of controllers, branch sites, and hubsites. It does not function as a log forwarder, BGP route reflector, or VPN concentrator. As an orchestrator, it manages the lifecycle of Versa VOS instances, enabling zero-touch provisioning and other orchestration functionalities through a single pane of glass.
