Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 356

What is the function of the LISP map resolver?

Answer options

• A. to connect a site to the LISP-capable part of a core network publish the EID-to-RLOC mappings for the site, and respond to map-request messages
• B. to advertise routable non-LISP traffic from one address family to LISP sites in a different address family
• C. to send traffic to non-LISP sites when connected to a service provider that does not accept nonroutable EIDs as packet sources
• D. to decapsulate map-request messages from ITRs and forward the messages to the MS

Correct answer: D

Explanation

The correct answer is D because the LISP map resolver is responsible for handling map-request messages by decapsulating them and forwarding them to the Mapping System (MS). Option A describes functions related to EID-to-RLOC mapping but does not specifically address the decapsulation of map requests. Options B and C pertain to traffic handling but are unrelated to the specific function of the map resolver.
