- B: greater scalability
- C: support for anycast gateway
- D: lower traffic overhead
- E: dynamic spoke-to-spoke tunnels
Question 10
How is Internet access provided to a WAN Edge router that is connected to a MPLS transport link?
- A: OMP advertises a default route from a WAN Edge router that is connected to the MPLS and Internet transport networks.

- C: An extranet must be provided in the MPLS transport network to allow private traffic to reach the public Internet.
- D: TLOC extensions are used to route traffic to a WAN Edge router that is connected to the Internet transport network.
