Designing Cisco Enterprise Networks (ENSLD) — Question 13

How do endpoints inside an SD-Access network reach resources outside the fabric?

Answer options

• A. a VRF fusion router is used to map resources in one VN to another VN
• B. Fabric borders use VRFs to map VNs to VRFs
• C. SD-Access transit links are used to transport encapsulated traffic from one fabric to another
• D. A fabric edge is used to de-encapsulate VXLAN traffic to normal IP traffic then transported over the outside network

Correct answer: D

Explanation

The correct answer is D because a fabric edge performs the crucial role of converting VXLAN-encapsulated traffic into standard IP traffic for transmission across the external network. The other options do not accurately describe the process of how traffic exits the SD-Access fabric; for instance, while VRF fusion and mapping are important, they do not specifically address the de-encapsulation process involved in reaching outside resources.
