問題3
As shown in the figure, the bearer network is deployed in full mesh mode. For example, RTA uses the physical interface ATM 1/0/0. The interface is devised into ATM 10/0.2 connect to RTC and RTD, respectively . The GigabiteEthernet 2/0/0 and GigabitEthernet 3/0/0 interface are used to set up a trunk as the VRRP heartbeat cable. The UMG work in active/standby mode. Media interface connected to RTA and RTB belong to VLAN 10. VRRP is enable at the VLAN interface RTA is the master router. The interface is configured as follows:
Which of the following RTA configurations are correct in VLAN 10?
A)
B)
C)
D)

Exhibit:
As shown in the figure, complex traffic classification is configured for RTA's upstream GigabitEthernet 1/0/0. The QoS is configured as follows:
A tester sends TCP packets from GE 1/1 to GE 1/2 at 40 1.2.2 IF DSCP values of packets GE receives are not 46, what are the possible causes?

問題7
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?
