• Question 211:

  There is the concept of forwarding equivalence class FEC in MPLS. The following description is wrong:

  A. MPLSGrouping packets with the same forwarding processing method is calledFEC
  B. a forwarding equivalence classFECA unique label value is assigned on all routers
  C. sameFECgrouped inMPLSThere will be different processing in the network
  D. FECThe division is very flexible. Can be the source address, and the address, source port, destination port, protocol type or VPNEqual to any combination of division basis
  B. a forwarding equivalence classFECA unique label value is assigned on all routers
  C. sameFECgrouped inMPLSThere will be different processing in the network

• Question 212:

  On the OSPFv3 network shown in the figure, area 1 is an NSSA. R1 imports the external route 2000::1/128 to OSPFv3. Which of the following LSAs does not exist in area 1?

  

  A. Inter-Area-Prefix-LSA
  B. NSSA LSA
  C. Intra-Area-Prefix-LSA
  D. AS-External-LSA
  D. AS-External-LSA

• Question 213:

  In an MPLS network, functions such as neighbor discovery, session establishment and maintenance, and label management are implemented by exchanging LDP messages between SRs running the DP protocol. To ensure the reliability of message delivery, all LDP messages are sent and received based on TCP connections.

  A. True
  B. False
  B. False

• Question 214:

  As shown in the figure, in a medium-sized network, BGP generally deploys dual RRs to improve R reliability. When deploying dual RRs, the Cluster IDs of the two RRs are generally set to be the same. The reason for this is

  

  A. Prevent RR from receiving too many routes and causing insufficient memory
  B. prevent suboptimal
  C. prevent loops
  D. Prevent the client from receiving too many routes and causing it to run out of memory
  A. Prevent RR from receiving too many routes and causing insufficient memory

• Question 215:

  A. Label release method - downstream autonomous methoD. label distribution control method - free methoD. label retention method - independent
  B. Label release method - free methoD. label distribution control method - independent methoD. label retention method - downstream autonomous method
  C. Label release method - downstream autonomous methoD. label distribution control method - independent methoD. label retention method - free method
  D. Label release method-independent methoD. label distribution control method-free methoD. label retention method-downstream autonomy
  C. Label release method - downstream autonomous methoD. label distribution control method - independent methoD. label retention method - free method

  A. R2in the area1and area0will generateRouter LSA
  B. R2WillR3GeneratedRouter LSAforward toR1
  C. R2WillR1GeneratedRouter LSAforward toR3
  D. R2only in area0generated inRouter LSA
  A. R2in the area1and area0will generateRouter LSA

• Question 217:

  In the topology shown in the figure, the entire network runsOSPFv3agreement inNoIn the case of attracting external routes,R1which type ofLAS?

  

  A. Intra-Area-Prefix-LSA
  B. Link-LSA
  C. Inter-Area-Router LSA
  D. Inter-Area-Prefix-LSA
  C. Inter-Area-Router LSA

• Question 218:

  In the VLAN aggregation technology, multiple Sub-VLANs are used to isolate wide-open domains, and these Sub-VLANs are aggregated.

  Synthesizing a logical Super-VLAN, a company divides different departments into different Sub-VLANs, because Sub-VL AN not only includes physical connection, but also can establish three-layer VLAN ANIF interface, which can directly carry out three-layer communication with external network.

  A. True
  B. False
  B. False

• Question 220:

  On the OSPFv3 network shown in the figure, OSPFv3 is enabled on the interfaces connecting R1, R2, and R3. The router ID of each router is 10.0.X.X, where X is the number of the router.

  If you check detailed information about an LSA on R3, the command output shows that R1 and R2 are DRs on the network.
