Huawei Exam H31-161 Topic 4 Question 73 Discussion

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?
