Answer
# 1
The IP virtual private network (VPN) feature for
Multiprotocol Label Switching (MPLS) allows a
Cisco IOS network to deploy scalable IPv4 Layer 3 VPN
backbone services. An IP VPN is the
foundation companies use for deploying or administering
value-added services including
applications and data hosting network commerce, and
telephony services to business customers.

MPLS VPNs allow service providers to deploy scalable VPNs
and build the foundation to deliver
value-added services, including:

Connectionless Service
Centralized Service
Scalability
Security
Easy to Create
Flexible Addressing
Integrated Class of Service (CoS) Support
&
Straightforward Migration
