RFC 3270 describes Differentiated Services （Diff-Serv） over Multi-Protocol Label Switching （MPLS）networks. Which model alters Differentiated Services （Diff-Serv） code points set in different DifferentiatedServices （Diff-Serv） domain？（）

A.Greater scalability is offered
B.The ASBR holds VPNv4 routes
C.Relative technical simplicity is offered
D.Lower relative security is offered
E.Multihop E-BGP between ASBRs is utilized
F.Better suitability for InterProvider VPNs is provided

A.LDP is primarily used in internal networks of MPLS-VPN providers.
B.MP-BGP is used for label distribution for VPN customer routes.
C.Directed LDP is used for label distribution in L2-VPN Attachement Circuits.
D.MP-BGP is used for label distribution in MPLS Traffic Engineered networks.

A.Amplification is prevented if global changes have only a local effect as opposed to systems in which global changes have a local effect
B.Amplification is prevented if local changes have only a local effect as opposed to system inwhich localchange have a global effect
C.Internet domain does not suffer from“The Amplification Principle”as BGP takes care of misbehaving advertisers
D.None of the above
