The network and VPN planning of a certain enterprise is shown in the figure. Please match the sites through which business traffic can communicate one by one.


As shown in the figure, when a network engineer is troubleshooting, he draws a schematic diagram of a multicast network. The IGIP version enabled by R1 and R2 is 2, PIM-SM is used as the multicast routing protocol, and other configurations are default configurations. The querier in the multicast network is ().

In the OSPFv3 network shown in the figure, area 1 is the Stub area.

Which of the following descriptions are correct by default? (Multiple choice)
- A . Both R1 and R2 will generate Network-LSA
- B . Default routes will be generated in the routing tables of R1 and R2
- C . Both R1 and R2 will generate Intra-Area-Prefix-LSA
- D . Both R1 and R2 will generate Inter-Area-Prefix-LSA
When IP packets pass through the MPLS network, the MPLS device will process the TTL. If the topology shown in the figure adopts the Pipe processing mode, which of the following are the TIL values in the IP packets?

- A . ① =255, ② =254, ③ =252
- B . ① =254, ② =254, ③ =253
- C . ① =255, ② =255, ③ =254
- D . ① =254, ② =253, ③ =252
In the OSPP network shown in the figure, R1 and R2 achieve Lopback0 interface interconnection through OSPF.

At the same time, R1 and R2 have enabled the MPLS LDP function, and the LDP transmission address is the IP address of the Loopback0 interface. The network engineer found that R1 and R2 could not establish an LDP session, so he first executed the command shown in the figure on R2. Based on this, which of the following reasons may cause the failure of establishing an LDP session between R1 and R2? (Multiple choice)
- A . R1 GE0/0/1 interface refuses to receive packets with a destination IP address of 224.0.0.5
- B . R1 GE0/0/1 interface refuses to receive ICP packets with destination port 646
- C . R2 GEO/0/1 interface refuses to receive packets with source IP address 10.0.12.1
- D . R2 GEO/0/1 interface refuses to receive packets with a destination IP address of 224.0.0.2
Which of the following information can be judged by observing the device indicator light and can also be viewed through the command line? (Multiple choice)
- A . Board operating status
- B . Version the device is running
- C . Link Connectivity
- D . Storage space size
In the OSPFv3 network shown in the figure, the OSPFv3 related parameters are the default configuration. When checking the LSDB on one of the devices, some content is omitted in the LSDB. The Router IDs of R1, R3, and R4 are 10.0.1.1, 10.0.3.3, and 10.0.4, respectively. The Origin Router part of some LSAs is hidden. Please complete this part.


ULA aggregation can be implemented within a physical network by isolating broadcast domains with multiple Sub-LANs and aggregating these Sub-LANs into a logical Super-LAN.
Which of the following descriptions about WAN combinations is correct?
- A . When configuring VLAN aggregation, you can configure VLAN1 as a Super-VLAN
- B . If Proxy ARP is enabled on the VLANIF interface to which the Super-VLAN belongs, all Sub-VLANs can establish corresponding ARP entries for intercommunication.
- C . If the core switch creates a Super-LAN and the corresponding VLANIF interface, then as long as there is a physical interface in the core switch that is Up, the ANIF interface status will be Up.
- D . If different Sub-VLANs belong to the same Super-VLAN, the hosts in these Sub-VLANs can directly communicate at Layer 2
When a network engineer logs in to a NetEngine AR6120 through the console port, he finds that the password is wrong and cannot log in. If the device can still be logged in through the Telnet account and the user account has the permission to change the console port password, he can log in to the device through Telnet and change the console port password.
- A . True
- B . False
