Cisco Enterprise Networks SDA, SDWAN and Catalyst Center for System Engineers — Question 4

What is a challenge of having an SD-Access Centralized design where a single fabric encompasses the main site and all branch sites across the WAN?

Answer options

• A. End to End Routing is not supported
• B. SSIDs would be the same across all sites
• C. DNA Center does not support it
• D. Since the traffic is encapsulated. SD-WAN features can't be used to optimize/route traffic.

Correct answer: A

Explanation

The correct answer is A because in a centralized SD-Access design, end-to-end routing cannot be maintained across the WAN due to the encapsulation of traffic. Options B and C are incorrect as having the same SSIDs across all sites is a typical feature, and DNA Center does support SD-Access. Option D is also incorrect as SD-WAN features may still be utilized, but this is affected by how traffic is managed.
