Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 776

Which device, in a LISP router architecture, receives LISP map requests and determines which ETR should handle the map request?

Answer options

• A. proxy ETR
• B. routing locator
• C. map resolver
• D. map server

Correct answer: C

Explanation

The correct answer is C, the map resolver, because it specifically handles incoming map requests and identifies the appropriate ETR for processing. The proxy ETR (A) serves a different role, acting on behalf of the ETRs, while the routing locator (B) is involved in directing traffic but does not handle map requests. The map server (D) stores the mapping information but does not determine which ETR should respond to requests.
