A. MPLS LSP is broken along the path.
B. The route-policy is not implemented in router PE-2.
C. The BGP local-as command should be used between PE-1 and CE-1.
D. The route-distinguisher values must match in both sites.
E. The BGP as-override command should be implemented between PE-1 and CE-1.
Answer: E

A. MPLS PHB mode
B. Pipe mode
C. IntServ mode
D. Uniform mode
E. Short-Pipe mode
Answer: E
Q3. Refer to the exhibit.
It displays the Router_3 FIB information without any OSPF LSDB optimization. An engineer wants to optimize the OSPF LSDB in accordance with RFC 1587 Considering the following restraints:

A. area 1 nssa default-information-originate
B. area n nssa no-summary
area 1 nssa no-redistribution
C. area 1 nssa no-redistribution
area 1 nssa default-information-originate
D. area 1 nssa no-summary
E. area 1 nssa no-redistribution
F. area 1 nssa no-summary
area 1 nssa default-information-originate
Answer: F

A. MPLS explicit null with pipe mode
B. MPLS implicit null with short pipe mode
C. MPLS implicit null with uniform mode
D. MPLS explicit null with uniform mode
E. MPLS explicit null with short pipe mode
F. MPLS implicit null with pipe mode

C. FEC is a group of IP packets that is forwarded over the same path, and with the same forwarding treatment.
D. FEC is a group of IP packets that is forwarded over a different path, but with the different forwarding treatment.
