Versa Networks Updated VNX100 Exam Questions and Answers by aden

To implement a third-party application server as a virtual machine on a Versa CPE, the Service Chain Template should be used. This is because the Versa uCPE solution supports service chaining capabilities which are necessary for steering traffic to and from third-party virtual network functions (VNFs) to Versa Operating System (VOS) instances. The Versa uCPE solution can manage the lifecycle of third-party VNFs, including the ability to bring up an out-of-band management interface for each VM, connecting it to the Versa secure management channel, and routing management and control plane traffic accordingly​​.

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.

By default, when configuring Direct Internet Access (DIA) through workflows, the protocol that runs between the tenant virtual router (VRF) and the transport WAN Virtual Router (VR), connected by the TVI interfaces, is EBGP (External Border Gateway Protocol). This protocol is used to control route distribution and is a fundamental part of the VOS Edge Device DIA Architecture. In such a configuration, the tenant VRF uses EBGP to advertise the default route, which is resolved using the logical tunnel created for DIA​​.

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.​
