What Approved 400-201 exam question Is?

Q1. Two Service Providers are beginning a merger between AS boundaries to provide MPLS-enabled services between their networks. Customers are using both Service Providers for services and, under certain circumstances; there are requirements to extend Layer 2 VPN circuits between each provider. The providers are in the process of completing the technical merger. However, the MPLS is not supported between the providers. Which action allows MPLS Layer 2 VPN circuits to be built over the inter-AS link? 

A. Create a GRE tunnel with the mpls ip command between ASBRs. 

B. Create Layer 2 VPN peerings between PE routers from each provider. 

C. Create a VPNv4 peering between ASBRs to advertise labels between each provider. 

D. Create a sham link between ASBR routers to enable a superbackbone peering for Layer 2 VPN signaling.

C. Encryption might be required depending on the request. 

D. The communication between the MD and the Content IAP happens over UDP port 161. 

E. QoS and CoPP should be implemented to protect and optimize the tasks.

A. R1 does not have an established LDP neighborship with the router announcing the 10.0.0.3/32 prefix. 

B. The 10.0.0.3/32 prefix is being null-routed in the downstream neighbor 

C. LDP peer is not configured to advertise a label for the 10.0.0.3/32 prefix 

D. BGP is not configured to exchange labels with the BGP peer advertising 10.0.0 3/32 prefix

A. Management traffic to RP from all non-MPP interfaces is dropped 

B. RP/DRP Ethernet Interfaces are not default out-of-band interfaces. 

C. MPP configuration changes doesn’t affect active sessions established before the changes 

D. Interfaces configured for out-of-band MPP are still part of global routing/forwarding 

E. If MPP is disabled and a protocol is activated, all interfaces cannot pass traffic 

F. LPTS will provide rate limiting
