Question #4

On the typical access network of a bearer network, a core network device connects to two upstream CEs. CEs connect to PEs in a square shape. This access network must bear voice and signaling services. A CE must be configured with two VPNs to separate the voice and signaling services and ensure high security and QoS. The signaling service works in active/standby mode, and the voice service works in load sharing mode. The VRRP must be enabled between the CEs to terminate the signaling flow. If the network robustness is ensured and the network architecture is rational, which of the following statements about the topological structure are true?

A. GE and FE links need to be used as the Eth-trunk between CEs to improve reliability.

B. The voice service must be carried by GE links and the signaling service must be carried by FE links.

C. The total link bandwidth between CEs cannot be less than that between CEs and PEs.

D. Instead of POS links, GE links are recommended between CEs and PEs.

Question #6

Which statement about primary VPN tunnel binding is false?

A. Primary VPN tunnel binding means to bind a tunnel to a specific VPN. The bound tunnel is exclusive to the VPN.

B. The bound primary tunnel can be selected sequentially.

C. Only the data destined for the specific peer device is transmitted through the n=bound primary VPN tunnel Data to other devices is transmitted using the default tunnel policy.

D. Primary tunnel ensures that data can be transmitted from a VPN t a specific peer device permanently through a dedicate TE tunnel.

Question #7

Which of the following statements about the L2VPN are true?

A. On a L2VPN, routing information of users does not need to be maintained or managed.

B. If the length of a L2VPN packet that arrives at a P node exceeds the maximum transmission unit (MTU) of relevant interfaces of the P node, the packet will be fragmented and then forwarded.

C. When providing the MPLS L2VPN service for enterprise users, the carrier must filter user route advertisements. Otherwise, flapping of user routes may lead to flapping of network routes.

D. When a traditional L2VPN (ATM and FR) is upgraded to an MPLS L2VPN, the network topology does not need to be adjusted.
