Palo Alto Networks (PANW) System Engineer (PSE) Practice Exam

Which environment uses software and virtualization to provide network connectivity for dispersed locations?

1. On-premise

2. SDN

3. SD-WAN

4. Nutanix

The correct answer is: SD-WAN

The correct choice is SD-WAN because it specifically leverages software-defined networking principles and virtualization to enhance network connectivity across multiple, widely dispersed geographical locations. SD-WAN solutions intelligently direct traffic over various connections (such as broadband, LTE, and MPLS) based on real-time assessments of network performance, which allows for improved resilience, performance optimization, and reduced costs associated with traditional WAN architectures. This technology is particularly beneficial for organizations with remote offices or branch locations, as it enables efficient routing of traffic and enhances overall connectivity while simplifying management and provisioning processes. In contrast, an on-premise environment typically refers to hardware and software that is installed and run locally on an organization’s premises, lacking the flexibility and geographical reach that SD-WAN provides. Software-Defined Networking (SDN) focuses more on the management and control aspects of networking, rather than specifically providing connectivity across dispersed locations. Nutanix is a cloud computing company that provides hyper-converged infrastructure solutions and is not directly related to network connectivity. Thus, SD-WAN stands out as the most accurate option concerning the question presented.
