                                    Huawei HCIE-Routing & Switching (Written) V3.0 Sample Questions:

                                    Question 1

                                    Although the STP protocol can solve the loop problem, the slow convergence of the network topology affects the user's communication quality. RSTP has made many improvements to STP. Which of the following is not an improvement of RSTP to STP?

                                    A. RSTP deletes 3 port states and adds 2 new port roles
                                    B. If a port does not receive the configuration BPDU sent by the upstream device within 4 consecutive Hello Time, the device considers that the negotiation with this neighbor has failed
                                    C. The non-root switch running RSTP sends configuration BPDUs at the interval specified by the Hello Timer. This behavior is completely performed by each device independently
                                    D. RSTP's port state specifications are divided according to whether the port forwards user traffic and learns MAC addresses, reducing the original five port states to three


                                    Question 2

                                    As shown in the figure, all interfaces of the router enable OSPF. Which of the following statements is correct?

                                    A. Type3 LSA generated by R6 in area 0 contains 10.0.2.2/32 routing information. Type3 LSA 1 will not be generated. Type3 LSA generated in area 1 contains 10.0.2.2/32 routing information.
                                    B. R5 in the area
                                    C. R3 in the area
                                    D. Type3 LSA generated by R4 in area 1 contains 10.0.2.2/32 routing information


                                    Question 3

                                    Which of the following technologies use tunneling technology to communicate between IPv6 addresses? (Multiple Choice)

                                    A. NAT64
                                    B. 6to4
                                    C. Dual Stack
                                    D. ISATAP


                                    Question 4

                                    What are the differences between traffic policing and traffic shaping? (Multiple Choice)

                                    A. For traffic policing, you can adjust the usage of the cache for traffic exceeding CIR.
                                    B. Apply traffic shaping in the direction of the entrance and use traffic policing in the direction of the exit.
                                    C. Traffic policing uses the token bucket algorithm, and traffic shaping uses the SPD algorithm.
                                    D. For traffic shaping, the router will buffer excess packets until the bandwidth is available again.
                                    E. For traffic shaping, you can adjust the usage of the buffer for traffic exceeding CIR.


                                    Question 5

                                    In addition to stateless address autoconfiguration, IPv6 devices can also obtain information such as address, gateway and DNS through DHCPv6.

                                    A. True
                                    B. False
