Correct Answer:

Explanation:

Which three options are restrictions for MPLS VPN BGP Local Convergence? (Choose three.)

• A.  This link protection can be initiated during a HA SSO. But links that were configured with this protection before the switchover begins remain protected after the switchover.
• B.  The MPLS VPN BGP Local Convergence feature affects only traffic that is exiting the VPN. Therefore, it cannot fully protect traffic end-to-end by itself.
• C.  The MPLS VPN BGP Local Convergence feature for IPv4/IPV6 supports the eBGP, RIP, EIGRP,OSPF, and dynamic routing protocols.
• D.  If you perform an in-service software downgrade from an image that does include this link protection to an image that does not support this feature, active protection is halted when BGP routes are refreshed.
• E.  Any next-hop core tunneling technology that is supported by BGP is also supported for protection, including MPLS, L2TPv3, and IP/GRE. CSC protocol between the PE and CE is also supported. Interautonomous system option A (back-to-back VRF) is supported because it is essentially the same as performing the PE-CE link protection in both autonomous systems. However, interautonomous system options B and C protection are not supported.

A network engineer is tasked with supporting traffic discrimination over MPLS traffic engineering tunnels. To allocate restricted bandwidth to a certain type of traffic with no QoS degradation, which technique must be used?

• B.  MPLS TE Diff-Serv Russian doll model
• C.  integrated services
• D.  MPLS TE Diff-Serv full allocation model
• E.  class of service
