- A . True
- B . False
In the OSPFv3 network shown in the figure, area 1 is the Stub area.
By default, which of the following types of LSAs is generated by only one router?
- A . Link-LSA
- B . Intra-Area-Prefix-LSA
- C . Network-LSA
- D . Inter-Area-Prefix-LSA
The debug output information of an OSPF router is shown in the figure. Which of the following is the Router ID of this router?
- A . 10.0.12.1
- B . 10.0.12.2
- C . 10.0.2.2
- D . 10.0.1.1
In the OSPFv3 network shown in the figure, the interconnected ports of R1, R2, and R3 have OSPFv3 enabled, and the Router ID of each device is 10.0.XX, where x is the device number. Check the detailed information of a certain LSA on R3, and you can infer from the output information that R1 and R2 are DRs in the network.
- A . True
- B . False
In the network shown in the figure, OSPF protocol is running between R1, R2, and R3, and OSPF BFD feature is turned on. IBGP neighbor relationship is established between R1 and R3 using loopback interface. If GE0/0/1 interface of R2 is shut down, and BGP neighbor relationship is checked on R1, by default, which of the following is the longest time for R1 BGP neighbor relationship to change from Up state to Down state?
- A . 60s
- B . 180s
- C . 40s
- D . 3s
In a certain MPLS network, the LSP information of R1 and R2 is shown in the figure. At this time, the administrator enters the command ping3.3.3 on R1. Which of the following descriptions of this scenario is correct?
- A . The Ping message sent by R1 does not carry any label. After receiving it, R2 will forward it based on IP.
- B . The Ping message sent by R1 will carry label 1025. After receiving it, R2 will remove the label and forward it based on IP.
- C . The Ping message sent by R1 will carry label 1025. After receiving it, R2 will perform label exchange and forward it based on MPLS.
- D . The Ping message sent by R1 does not carry any label, but R2 will add a label after receiving it and forward it based on MPLS
In the Hub&Spoke network shown in the figure, in order to achieve correct routing transmission, the administrator must manually configure which of the following commands on the Hub-PE?
- A . [Hub-PE-bgp-VPN_out] peer xxxx allow-as-loop
- B . [Hub-PE-bgp-VPN_out] peer xxxx soo 200:1
- C . [Hub-PE-bgp-VPN_in] peer xxxx soo 200:1
- D . [Hub-PE-bgp-VPN_in] peer xxxx allow-as-loop
As shown in the figure, the message is forwarded based on MPLS in the network. When PE2 receives the message sent by P2, which of the following is the label value carried in the message?
- A . No label
- B . 1033
- C . 3,1033
- D . 3
As shown in the figure, an administrator configures static LSP between routers R1~R4. Which of the following configuration options are correct? (Multiple choice)
- A . [R2] static-lsp transit test incoming-interface GigabitEthernet 0/0/0 nexthop 10.0.23.3 out-label 300
- B . [R3] static-lsp transit test in-label 300 nexthop 10.0.34.4 out-label 400
- C . [R4] static-lsp egress test incoming-interface GigabitEthernet 0/0/0 in-label 400

In the OSPF network shown in the figure, the link cost value has been marked in the figure. R1 has enabled OSPF IP FRR and configured the "maximum load-balancing 8" command in the OSPF process. If a service reaches 10.0.3.3/32 through the path R1-R5-R3, which of the following is the backup outbound interface of the service?
- A . No backup outbound interface
- B . GE0/0/2
- C . GE0/0/3
