最新的 CCIE Service Provider 400-201 免費考試真題:

1. A service provider is using point-to-multipoint TE to forward MPLS traffic from one source to multiple destinations, what is a restriction of using this method?

A) Only node protection is supported on point-to-multipoint TE LSPs
B) Point-to-multipoint TE does not support policy-based routing
C) Multicast traffic must be implemented using PIM sparse mode
D) Destinations must be manually added and removed on the TE tail-end router

2. In the MVPN profile 3 ( Rosen GRE with BGP-AS), which information is included inside of the opaque value?

A) Type 1-source-PE: Global-ID
B) Type 2- Root Address: VPN-ID; 0-n
C) RD:S,G
D) Not applicable for this profile

3.
Refer to the exhibit. The red dashed lines represent the preferred paths for the MPLS TE tunnel 1 and MPLS TE tunnel 2 to reach RTE3. The black dotted lines are the less desirable path In case RTA or RTD fails, the MPLS TE tunnel 1 and MPLS TE tunnel 2 preempt the MPLS TE tunnel 3. This causes a lack of the MPLS connectivity from CRS3 Which solution avoids the MPLS TE tunnel 3 to be teardown by the MPLS TE tunnel 1 and MPLS TE tunnel 2?

A) change the MPLS TE tunnel 3 priority values to 4 6
B) use affinity and link coloring in all MPLS TE tunnels and MPLS TE link resources
C) use the exclude option on the explicit path configuration for the MPLS TE tunnel 1 and MPLS TE tunnel 2
D) lower the signaled-bandwidth value of the MPLS TE tunnel 3
E) change the MPLS TE tunnel 3 priority values to 6 4

4. What is MPLS VPN component used by Multi-VRF solution?

A) VPN forwarding
B) Route distinguisher
C) Default MDT
D) Route target community

5. Which of the following comparison of Control Plane Policing (CoPP) with Receive ACL (Racl) is correct?

A) CoPP supports rate limits; Racl does not support rate limits
B) CoPP protects against IP spoofing; Racl protects against DoS attacks.
C) CoPP can not use named access lists; Racl can use named access lists
D) CoPP needs a AAA server, Racl does not need a AAA server
E) CoPP applies to a dedicated control plane interface; Racl applies to all interfaces.
