The CTO of a company requires the support of a network consultant to deliver an MPLS solution without resigning to a certain degree of redundancy and scalability. Which solution effectively scales to hundreds or thousands of sites?

• A.L3VPN with direct LSP connectivity between all PEs.
• B.L3VPN using a hierarchical topology of N-PEs and U-PEs.
• C.L2VPN with the broadcast traffic processed at the ingress PE.
• D.L2VPN by encapsulating multiple frame formats with interworking.

Refer to the exhibit. Which effect of this configuration is true?

• A.It configures an IPv4 peering with 192.168.1.1
• B.It configures VPWS single homed.
• C.It configures VPWS multihomed.
• D.It configures MPLS traffic engineering.

Which Layer 2 VPN technology is implemented over an IP core network without the need for MPLS?

• A.VPWS
• B.AToM
• C.L2TPv3
• D.VPLS

An ISP provides a major client MPLS VPN for managed services. The MPLS engineering team needs to use the advanced VPN feature of selective VRF import so that only specific prefixes are present in the required VPNs.
Which aspect of this feature must the team consider?

• A.The routers that are imported in the VRF can be BGP and IGP routes, so other match conditions in the route map, besides communities, can be used.
• B.The import-map command is applied under the PE interface that connects to the CE router.
• C.A route must pass the import route map first and then the route target import filter.
• D.A route is imported into the VRF only when at least one RT that is attached to the route matches one RT that is configured in the VRF and the route is permitted by the import route map.
