Huawei HCIE-Routing&Switching (Written)(Huawei Certified ICT Expert-Routing & Switching) Sample Questions:
1. Regarding the certification of the ISIS protocol, which statements are correct? (Multiple Choice)
A) After the interface authentication is configured, the IIH that the router sends must carry the authentication TLV.
B) Interface authentication can authenticate hello packets of Level-1 and Level-2.
C) Two routers are configured for regional authentication and interface authentication. The passwords are the same, so the two can establish neighbor relationship.
D) After the area authentication is configured, the IIH, SNP, and LSP sent by the router must be connected to the authentication TLV.
2. Which of the following is optimal for building a loop-free Layer 2 network?
A) Stacking + link aggregation
B) TRILL+MSTP
C) Stacking + MSTP
D) Link Aggregation + MSTP
3. The LAND attack is performed by the attacker sending a source address and a destination address to the destination host are the destination host, the same SYN packet on source port and the destination port. When the receiver waits for the final ACK packet from the sender, the connection is always in a semi-connected state, resulting in waste of limited TCP resources at the receiving end.
A) True
B) False
4. Which of the following is the correct description of OSPF adjacency and link state database synchronization?
A) When the state of the OSPF router reaches the LOADING state, the FULL adjacency is formed.
B) The adjacency relationship starts from the EXSTART state.
C) The INT status indicates that the router has received a Hello packet from the neighbor and the Hello packet already contains its own router ID.
D) FULL adjacencies are formed between all routers in the broadcast network.
5. As shown in the following figure, enterprises hope to achieve successful access VPN between headquarters and branches through MPLS.
Branch office VPN traffic must be forwarded through the headquarters for traffic monitoring.
Which of the following statement about this solution is wrong?
A) BGP can be used to exchange VPN routing information between the CE and the PE.
B) You can establish an MP-IBGP peer relationship between the Spoke-PEs and exchange VPN routing information.
C) OSPF can be used to exchange routing information between the Hub-CE and the Hub-PE and between the Spoke-PE and the Spoke-CE.
D) When Hub-CE and Hub-PE use EBGP to transmit routing information, the Hub-PE must be able to accept routes that are repeated by the AS number to receive routes advertised by the Hu-CE.
