What is true about the address-family commands?
A. They specify the unicast or multicast address prefixes.
B. They enable the address family and enter privileged mode.
C. You enter the command from global configuration mode.
D. To disable the address family mode, use the address-family disable command.
A
What is true about PE-to-CE routing requirements?
A. An MPLS VPN implementation differs greatly from a dedicated router peer-to-peer model implementation.
B. The CE router requires a specific configuration to be a part of an MPLS VPN domain.
C. Routing protocols that can run between a CE router and a PE router include EIGRP, RIPv2, OSPF, EBGP, and static routes.
D. From the provider core router perspective, the MPLS VPN backbone is much more complicated.
C
What is true about the address-family commands?
A. They split apart the configuration for each address family.
B. They group together at the beginning (highest level) of the configuration.
C. They apply only to unicast address-family traffic.
D. The commands that are independent of the address family group at the end.
A
What is true about import and export targets?
A. RTs attached to the route are called export RTs and are configured separately for each virtual routing table in a PE router.
B. When the VPNv4 routes propagate to other PE routers, those routers must export the routes into their virtual routing tables.
C. A single prefix can associate to only one export route target when it propagates across the MPLS VPN network.
D. The RTs associate to sites that belong to one VPN only.
A
What is true about PE-to-CE routing requirements?
A. Provider core routers exchange VPNv4 routes via MP-IBGP sessions with other core routers.
B. The core routers are the only routers in MPLS VPN architecture that see all routing aspects of the MPLS VPN.
C. CE routers exchange core routes with core routers and other CE routers.
D. PE routers exchange IPv4 VPN routes with CE routers via various routing protocols that run in the virtual routing tables.
D
What is true about import and export policies?
A. Cisco IOS XR Software uses route maps for matching routes and setting their parameters.
B. Route policies are not compiled into a run-time executable portion of code.
C. Policies can define more-specific conditions for exporting and importing routes into or from a VPN.
D. They can invoke other route policies, much like a C program is able to call separately defined functions.
D
Match the following VPN types with the correct description.
Descriptions:
Provides business partner access to public servers at the headquarters site.
Customer CE routers are located in a service provider subnet.
Provides shared access, however there is no connectivity between customers.
This VPN type does not exist.
VPN Types:
customer access VPN
network management VPN
Internet access VPN
extranet VPN
Provides business partner access to public servers at the headquarters site. = extranet VPN
Customer CE routers are located in a service provider subnet. = network management VPN
Provides shared access, however there is no connectivity between customers. = Internet access VPN
This VPN type does not exist. = customer access VPN
