Which statements accurately describe a partial mesh VPN deployment?

In a partial mesh VPN deployment, not every site is connected to every other site directly, which distinguishes it from a full mesh architecture where all locations have direct tunnels to one another. Instead, specific connections exist between certain sites based on need or communication patterns, which means that VPN tunnels are selectively configured between locations rather than universally established. This design allows for efficient use of resources and bandwidth, optimizing the network based on actual traffic demands.

The other options do not align with the definition of a partial mesh. For instance, if VPN tunnels interconnect between all locations, it would describe a full mesh deployment, which is not the case here. Also, while sites in a partial mesh may indeed communicate via direct tunnels, not all sites are interconnected, dispelling the idea that all locations have direct tunnels. Additionally, the presence of hub locations is not inherently excluded; a partial mesh can include hub-and-spoke topologies where certain sites act as hubs for others. Thus, the selected answer accurately reflects the characteristics of a partial mesh VPN.
