Why do Cisco MPLS TE tunnels require a link-state routing protocol?
AThe link-state database provides segmentation by area, which improves the path-selection process.
BThe link-state database provides a data repository from which the tunnel endpoints can dynamically select a source ID.
CLink-state routing protocols use SPF calculations that the tunnel endpoints leverage to implement the tunnel.
DThe tunnel endpoints use the link-state database to evaluate the entire topology and determine the best path.

A regional MPLS VPN provider operates in two regions and wants to provide MPLS L3VPN service for a customer with two sites in these separate locations. The
VPN provider approaches another organization to provide backbone carrier services so that the provider can connect to these two locations.
Which statement about this scenario is true?
AWhen edge routers at different regional sites are connected over the global carrier backbone, MP-eBGP must run between the routers to exchange the customer VPNv4 routes.
BWhen eBGP is used for label exchange using the send-label option, MPLS-BGP forwarding is configured under the global ABC CSC PE-to-CE interface.
CWhen BGP is used for both route and label exchange, the neighbor a.b.c.d send-label command is used under the address-family VPNv4 command mode.
DWhen IGP is used for route exchange and LDP for label exchange, MPLS is enabled only on the VRF interface on the backbone-carrier PE side.

CLabel 0 is used for the prefix displayed, but will not be part of the MPLS label stack for packets destined for 192.168.10.10.
DLabel 3 is in use for the prefix displayed and will be part of the MPLS label stack for packets destined for 192.168.10.10.
ELabel 0 is used for the prefix displayed and will be part of the MPLS label stack for packets destined for 192.168.10.10.
