Huawei HCIE-Routing&Switching (Written)(Huawei Certified ICT Expert-Routing & Switching) Sample Questions:
1. 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) You can establish an MP-IBGP peer relationship between the Spoke-PEs and exchange VPN routing information.
B) BGP can be used to exchange VPN routing information between the CE and the PE.
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.
2. In the case of not dividing the area, which of the following description is true about the link state routing protocol? (Multiple Choice)
A) The router will send all the wrong path status information sent by one neighbor to all other neighbors to ensure the synchronization of the database.
B) Each router establishes a topological structure of the entire flood domain
C) Routers in the entire flooding domain have the same wrong path state database
D) Routers in the flooding domain may repeatedly receive the same link state information.
E) Each router learns the route directly from the routing update and adds it to the routing table.
3. There is an AS-path-filter, ip as-path-filter 1 permit ^100(_100)*(_400)*, which AS-PATH attribute cannot be matched by the As-path-filter?
A) 100 200 900
B) 100
C) 100 400 400 400
D) 100 400
4. The order for the protocols using TCP ports 443, 179, 137, 110, and 23 is:
A) Https, BGP, Netbios Name server Pop3, TelNet
B) Finger, DHCP Server, NetBios Name Server, POP3, Telnet
C) LDAP, SNMP, TFTP, POP3, Telnet
D) Https, SNMP, Pop3, DNS, Telnet
E) BGP, POP3, SNMP, TFTP, Telnet
5. Which of the following description of the establishment process of LDP LSP is correct? (Multiple choice)
A) The process of establishing an LSP is actually the process of binding the FEC to the label and advertising the binding to the upstream LSR of the LSP.
B) Label distribution in the DoD mode, for a specific FEC, the LSR does not need to obtain the label request message from the upstream to perform label distribution.
C) When the network topology change causes the next hop neighbor to change, use free label retention way, the LSR can directly reestablish the LSP by using the label sent by the original non-optimal next hop neighbor.
D) By default, the LSR is for the same FEC. The received label mapping can only come from the optimal next hop. It cannot be from the non-optimal next hop.
