Designing Cisco Enterprise Networks (ENSLD) — Question 83

How is Internet access provided to a WAN Edge router that is connected to a MPLS transport link?

Answer options

• A. OMP advertises a default route from a WAN Edge router that is connected to the MPLS and Internet transport networks.
• B. Internet access must be provided at the WAN Edge router through either a 4G/5G link or local Internet circuit.
• 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.

Correct answer: D

Explanation

The correct answer is D because TLOC extensions are specifically designed to route traffic to WAN Edge routers connected to the Internet. Option A is incorrect as OMP does not directly provide Internet access. Option B suggests alternative methods that don't involve the MPLS transport link, while option C misinterprets the role of an extranet in this context.
