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

                                    1. Which of the following description about the related information of BGP4+ is correct? (Multiple choice)

                                    A) Modifying the Router ID of the BCP will cause the BGP connection between the routers to be re-established.
                                    B) Bgp4+ can use the dampening command to suppress IBGP routes.
                                    C) The Next Hop attribute in BCP4+ is represented by the Pv6 address, which can be the link-local address of the next hop.
                                    D) BGP4+ does not support automatic route aggregation.


                                    2. Which of the following statements about static VXLAN channel configuration are correct? (Multiple choice)

                                    A) For a VXLAN tunnel, a one-to-one corresponding NVE interface needs to be created, in which the source IP address and destination IP address are clearly specified. Therefore, there are multiple VXLAN tunnels on VTEP. The corresponding number of NVE interfaces must be configured
                                    B) In the NVE interface, the destination address of the VXLAN tunnel can be specified by the address in the head-end copy list. Multiple VXLAN tunnels can only create one NVE interface
                                    C) One NVE interface can be associated with multiple VNIs, so when there are multiple BDs, only one NVE interface can be created
                                    D) A BD needs to create an NVE interface, when there are multiple BDs, multiple NVE interfaces must be created


                                    3. Compared with the OSPFv2 message header, what fields are added in the OSPFv3 message header?

                                    A) Instance ID
                                    B) IPv6 Auth Type
                                    C) Link ID
                                    D) IPv6 Router ID


                                    4. Which of the following description about the label space of MPLS is wrong?

                                    A) 16~1023 is the label space shared by static LSP and static CR-L SP
                                    B) Above 1024 is the label space shared by dynamic signaling protocols such as LDP, RSVP-TE, MP-BGP, etc.
                                    C) When the penultimate hop LSR performs label switching, if the value of the label after the exchange is found to be 3, the label will be ejected by default and the packet will be sent to the last hop
                                    D) If the outgoing label value is 0, the router will directly discard the packet


                                    5. Traditional BGP-4 can only manage IPv4 unicast routing information. In order to provide support for multiple network layer protocols, MP-BGP extends BGP-4.
                                    MP-BGP uses address families to distinguish different network layer protocols. Which of the following address families are currently supported? (Multiple Choice)

                                    A) BGP-IPv6 unicast address family
                                    B) BGP-VPN instance IPv6 address family
                                    C) DBGP-IPv4 broadcast address family
                                    D) BGP-VPNv4 address family
