SR-MPLS publishes labels and reserves bandwidth through extended IGP to support large-bandwidth services.
- A . True
- B . False
In Huawei’s SD-WAN networking solution, RR must use independent equipment and cannot be deployed on the same equipment as CPE.
- A . True
- B . False
In the firewall dual-machine hot backup scenario, each firewall has a VGMP group. By default, the VGIMP group is in which of the following working states?
- A . Active
- B . Initialize
- C . Load Balance
- D . Standby
The output information of a certain router is as shown in the figure. Which item is wrong in the following description?
- A . The tunnel has the Keepalive check function enabled.
- B . The destination IP address of the tunnel is 10.0.3.3
- C . This tunnel is a GRE tunnel
- D . The keyword verification function is not enabled for this tunnel.
OSPF fast convergence is an extended feature designed to improve the convergence speed of routes. The working principle of PRC (Partial Route Calculation) is: when the network topology changes, only the affected nodes are path calculated. , thereby speeding up route calculation.
- A . True
- B . False

PC1 has learned the ARP information of PC2. When the ARP request sent by PC1 for PC2 is forwarded by VTEP1 to VTEP2, which of the following is the destination MAC address of the inner data frame?
- A . MAC A
- B . MAC D
- C . MAC C
- D . MAC B
As shown in the figure, Site1 and Site2 need to achieve mutual access through the operator’s BGP/MPLSIPVPN. It is known that the public network tunnel between PE1 and PE2 has been established (the label information is as shown in the figure), and PE1 has set 192.168 in Site1. The route of network segment 1.0/24 is advertised to PE2 through the MP-IBGP neighbor relationship, and route learning is normal.
When crawling Site2 to access the 192.168.1.0/24 data of Site1 between P and PE1, which of the following is the outermost label?
- A . 3
- B . 8888
- C . 6662
- D . 6661

A certain network runs SR-MPLS. Now R1 wants to access R7, and its label stack is as shown in the figure. Which of the following may be the paths for R1 to access R7? (Multiple choice)
- A . R1-R3-R5-R7
- B . R1-R2-R4-R6-R7
- C . R1-R2-R4-R5-R7
- D . R1-R3-R5-R4-R7
