Two spoke sites are connected to a single Cisco SD-WAN hub site. Which two features are required to configure dynamic tunnels between the two spoke sites? (Choose two.)

To enable direct dynamic spoke-to-spoke tunnels, the 'tloc-action backup' command in a control policy needs to be applied to the hub router. This policy instructs the hub to advertise the TLOCs of other spokes to a requesting spoke, facilitating direct tunnel establishment without always hair-pinning traffic through the hub.

Applying 'tloc-action backup' on spokes is not the correct mechanism for enabling dynamic spoke-to-spoke tunnels; this action is relevant to the hub's role in advertising TLOCs.

Traffic engineering service on the spokes is not the primary feature for enabling dynamic spoke-to-spoke tunnels, although it can influence how traffic uses those tunnels once established.

Traffic engineering service on the hub is not the primary feature for enabling dynamic spoke-to-spoke tunnels.

The 'tloc-list' command is used to group TLOCs, often for policy application, but it is not the specific command that enables the dynamic spoke-to-spoke tunnel feature itself.
