What advantages are there in using a hub-and-spoke IPSec VPN configuration instead of a fully- meshed set of IPSec tunnels? (Select all that apply.)

Full redundancy is often more directly achieved with a full-mesh topology, or requires additional redundant hubs in a hub-and-spoke setup, making it not inherently simpler or required for full redundancy.

A hub-and-spoke topology significantly simplifies VPN configuration because each spoke site only needs to establish a single tunnel to the central hub, rather than a tunnel to every other site.

The choice of VPN topology (hub-and-spoke vs. full-mesh) does not impact the strength of the encryption algorithms used; encryption strength is determined by the configured cipher suites and key lengths.

For N sites, a hub-and-spoke topology requires N-1 tunnels (one from each spoke to the hub), which is a much lower number compared to the N*(N-1)/2 tunnels required for a full-mesh topology.
