Common mistakes.
- A. Providing access to business internet is a general SD-WAN transport function, not the specific purpose of the TLOC extension feature.
- C. TLOC extension is not an alternate or redundant path to a transport the device is already connected to; it provides access to a transport the device cannot reach on its own.
- D. Configuration synchronization between neighboring WAN Edge routers is handled by OMP and vManage, not by the TLOC extension interface.
