What are the deployment options available for a Physical Service Edge?

The correct answer highlights the two primary deployment options for a Physical Service Edge, which are single-arm and dual-arm configurations.

In a single-arm deployment, the Physical Service Edge connects to the network through a single interface. This setup is straightforward and typically used in scenarios where there is sufficient redundancy or where the traffic flow does not necessitate complex routing or segmentation.

In contrast, a dual-arm deployment involves two interfaces, allowing the Physical Service Edge to connect to different segments of the network or multiple networks simultaneously. This setup enhances redundancy and allows for better traffic management, as it can handle more complex network structures and optimize performance by distributing workloads across the two interfaces.

The terms used in the other options, such as tri-arm or quad-arm, are not standard configurations for a Physical Service Edge, and therefore are not recognized deployment methods in this context. The focus on single-arm and dual-arm configurations aligns with commonly deployed practices, ensuring clarity for users regarding how to implement and utilize Physical Service Edges effectively.
