Explanation
ITR is the function that maps the destination EID to a destination RLOC and then encapsulates the original packet with an additional header that has the source IP address of the ITR RLOC and the destination IP address of the RLOC of an Egress Tunnel Router (ETR).
After the encapsulation, the original packet become a LISP packet.
ETR is the function that receives LISP encapsulated packets, decapsulates them and forwards to its local EIDs. This function also requires EID-to-RLOC mappings so we need to point out an "map-server" IP address and the key (password) for authentication.
A LISP proxy ETR (PETR) implements ETR functions on behalf of non-LISP sites. A PETR is typically used when a LISP site needs to send traffic to non-LISP sites but the LISP site is connected through a service provider that does not accept no routable EIDs as packet sources. PETRs act just like ETRs but for EIDs that send traffic to destinations at non-LISP sites.
Map Server (MS) processes the registration of authentication keys and EID-to-RLOC mappings. ETRs sends periodic Map-Register messages to all its configured Map Servers.
Map Resolver (MR): a LISP component which accepts LISP Encapsulated Map Requests, typically from an ITR, quickly determines whether or not the destination IP address is part of the EID namespace

Explanation
In VRF-Lite, Route distinguisher (RD) identifies the customer routing table and allows customers to be assigned overlapping addresses. Therefore it can support multiple customers with overlapping addresses -> Answer 'It can support multiple customers on a single switch' is correct.
VRFs are commonly used for MPLS deployments, when we use VRFs without MPLS then we call it VRF lite
->Answer 'It supports MPLS-VRF label exchange and labeled packets' is not correct.
- VRF-lite does not support IGRP and ISIS. ( -> Answer 'It supports most routing protocols, including EIGRP,ISIS, and OSPF' is not correct) - The capability vrf-lite subcommand under router ospf should be used when configuring OSPF as the routing protocol between the PE and the CE. - VRF-lite does not affect the packet switching rate. (-> Answer 'It can increase the packet switching rate' is not correct) Reference:

In Cisco routers, the codes for a traceroute command reply are:
! - success * - time out N - network unreachable H - host unreachable P - protocol unreachable A - admin denied Q - source quench received (congestion) ? - unknown (any other ICMP message)In Cisco routers, the codes for a traceroute command reply are:
