The exhibit displays a classic hub-and-spoke network topology. The arrows explicitly illustrate the traffic path originating from Spoke 1, traveling to the central Hub, and then being forwarded to Spoke 2. In this configuration, the hub acts as a central transit and policy enforcement point for all communication between the spoke sites. This method of routing inter-branch traffic through a central location is defined as "spoke-to-spoke via hub." This design is often used to centralize security services and simplify routing logic, as spokes only need to maintain a connection to the hub.

A. spoke-to-spoke only: This option is too general and ambiguous; it fails to specify whether the communication path is direct or indirect (via a hub), which is the key detail shown in the exhibit.

C. spoke-to-spoke direct: This topology would show a direct communication link or tunnel between Spoke 1 and Spoke 2, bypassing the hub entirely. The exhibit clearly shows traffic traversing the hub.

D. spoke-hub-hub-spoke: This describes a more complex multi-hub or hierarchical topology where traffic passes through two hubs to get between spokes, which is not depicted in the single-hub diagram.

Release 21.2.2. In the "Topologies" chapter

the "Hub-and-Spoke Topology" section describes this model where "spokes connect to one or more hubs" and the hub manages the data plane traffic between spokes. This confirms the hub's role as an intermediary.

" under the "Flexible and full-featured topologies" section (page 29)

explains the hub-and-spoke model where all traffic from a spoke site is directed to the hub site

which then routes it to the final destination

including other spokes.
