Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 964

How does the Cisco SD-Access control plane simplify traditional routing environments?

Answer options

• A. Routing adjacencies are no longer required.
• B. Separation of EID and RLOC reduces the size of routing tables.
• C. Routers query all routes to the map server.
• D. Full routing tables are shared and ensure that all routers know all paths within the underlay fabric and overlay.

Correct answer: B

Explanation

The correct answer, B, highlights that the separation of Endpoint Identifiers (EID) and Routing Locators (RLOC) leads to smaller routing tables, which is a key benefit of the Cisco SD-Access architecture. Other options, such as A, C, and D, either misrepresent the functionality of the SD-Access control plane or describe traditional routing processes that are not simplified by SD-Access.
