Question 16
As shown in the figure, CEs connect to users 1 and 2 through access
interfaces or links.
[Quidway-GigabitEthernet1/0/4]portswitch
[Quidway-GigabitEthernet1/0/4]port link-type access
[Quidway-GigabitEthernet1/0/4]port default vlan 1
[Quidway-GigabitEthernet1/0/6]portswitch
[Quidway-GigabitEthernet1/0/6]port link-type access
[Quidway-GigabitEthernet1/0/6]port default vlan 2
[Quidway-GigabitEthernet1/0/3]portswitch
[Quidway-GigabitEthernet1/0/3]port link-type trunk
[Quidway-GigabitEthernet1/0/3]port trunk permit-pass vlan 1 to 2
Users 1 and 2 require different network transmission quality. Which of the following methods are feasible to configure 802.1p priority 1 for packets of user 1 and 802.1p priority 2 for packets of user
2?

interfaces or links.

[Quidway-GigabitEthernet1/0/3]port trunk permit-pass vlan 1 to 2
Users 1 and 2 require different network transmission quality. Which of the following methods are feasible to configure 802.1p priority 1 for packets of user 1 and 802.1p priority 2 for packets of user
2?

Question 17
In the access architecture of an IP bearer network, the OSPF protocol is enabled between two access routers, two firewalls (in transparent mode), and two Layer 3 switches. Softswitches work in active/standby mode. VRRP is enabled between the softswitches to provide a gateway. In normalcases, SW1 is the master router and SW2 is the backup router. Considering the reliability of the access network, how would you plan the cost value of each link in the OSPF area?
Question 18
As shown in the figure, the mapping between links and administrative groups is as follows:
0x0F for A -> B; 0xFF for B -> C; 0xF0 for A -> C; 0xC3 for B -> D; and 0x3C for C -> D.
It is expected to configure a tunnel (affinity: 0x0C; mask: 0xFF) on node A to connect to RTD. Which path will be created along with the tunnel?

Question 19
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?
