Pages 465/466 of the Cisco OCG states this very very clearly. The order is Resolver (accepts map requests) Server (learns EID mapping entries from an ETR) Proxy ETR (LISP to non-LISP) ITR (receives packets from site-facing interfaces)

Wrong , I believe this is the correct answer. accept LISP encapsulated map request LISP MAP RESOLVER learns of EID prefix mapping entries from an ETR LISP MAP SERVER receives traffic from LISP sites and sends it to non-LISP sites LISP ITR receives packets from site facing interfaces LISP PROXY ETR –Ingress Tunnel Router (ITR): An ITR is a LISP Site edge device that receives packets from site-facing interfaces (internal hosts) and encapsulates them to remote LISP sites, or natively forwards them to non-LISP sites. –Egress Tunnel Router (ETR): An ETR is a LISP Site edge device that receives packets from core-facing interfaces (the transport infrastructure), decapsulates LISP packets and delivers them to local EIDs at the site.

Not really, the keyword here is non-LISP sites, so Proxy components are automatically involved. ITRs accepts traffic from the internal site hosts that are sent to other LISP sites. ETRs can publish the EID to RLOC mappings from their site and also forward requests to internal hosts coming from ITRs or xTRs.
