H12-211 : HCIA Routing & Switching : Part 12

1. According to the topology and configuration of interconnected interfaces of switches shown in the figure, the data frame tagged with VLAN 10 can be forwarded correctly between the two switches.

   

   

   • True
   • False

2. The network administrator creates VLAN 10 and assigns an IP address to VLANIF10. When using the command “display ip interface brief”, the administrator finds that VLANIF10 is down. What should be done to enable VLANIF10?

   • Use the command “undo shutdown” under the interface view for VLANIF10
   • Assign a physical interface that has either an active of inactive physical state to VLAN 10
   • Assign only a physical interface that has an active physical state to VLAN 10
   • Add an interface that has an active physical state and a trunk port associated with VLAN 10

3. A network administrator wishes to implement VLAN 10 to isolate certain users. It is common however for these users to often change their physical location. Which of the following VLAN implementations should be used?

   • Port based VLAN assignment
   • Protocol based VLAN assignment
   • MAC based VLAN assignment
   • IP subnet based VLAN assignment

4. Refer to the graphic. GE0/0/1 and GE0/0/2 on the switch are configured as hybrid interfaces. Which of the following statements are true? (Choose all that apply)

   

   

   • The administrative department and the finance department cannot communicate with each other because the VLANs of the two departments are different.
   • The data frames sent by the administrative department carry tagged VLAN 20 on the switch.
   • On the switch, the data frames sent by the finance department carry tagged VLAN 20.
   • The switch can be a Layer 2 or Layer 3 switch because communications do not need to be transmitted through a Layer 3 gateway.
   • If GE0/0/1 and GE0/0/2 on the switch are changed to trunk ports, the administrative department and finance department can communicate with each other.

5. On the VRP, what is the function of the “interface vlanif <vlan-id>” command?

   • It is used to create a VLANIF interface
   • It is used to create a VLANIF interface and enter the VLANIF interface view
   • It is used to configure a VLAN for a VLANIF interface
   • There is no such command

6. InARP resolves the protocol address of the remote device on each virtual circuit, including IP addresses and IPX addresses.

   • True
   • False

7. On an FR network, the DLCI identifies a virtual circuit on an interface. The DLCI must be unique during planning and deployment.

   • True
   • False

8. If AAA authentication is used on Huawei devices and the remote server does not respond, the authentication can be performed on network devices.

   • True
   • False

9. An ACL does not filter traffic generated by the Huawei device towards other devices, but only filters forwarded traffic, including traffic generated by other devices to access the Huawei device.

   • True
   • False

10. Which of the following statements are true about ACL deployment on Huawei devices? (Choose all that apply)

    • ACL can only be used in the outbound direction of an interface
    • The same ACL can be used on multiple interfaces
    • The ACL rules can only be configured in the following sequence: 10, 20, 30…
    • ACLs cannot be used to filter OSPF traffic because OSPF does not use UDP to encapsulate packets
    • ACLs can be used to match with the TCP/UDP port IDs of packets and to designate the port ID range

11. SNMP packets are encapsulated in TCP packets.

    • True
    • False

12. In OSPFv3, router IDs can be used automatically generated by the system.

    • True
    • False

13. VLSM can expand any IP network segment, including Class D addresses.

    • TRUE
    • FALSE

14. Refer to the graphic, 00e0-fc99-9999 is a specific host MAC address learned by a switch through ARP and the host changes the IP address three times.

    

    • TRUE
    • FALSE

15. There are two routers (RTA and RTB) between the source device and destination device. The Tracert command is used to detect the path between the two devices. During detection of the first hop (RTA), the source device sends a UDP packet with a TTL of 1 to an interface with a large interface number on the destination device. The TTL turns to 0 when the packet arrives at RTB, upon which RTA sends an ICMP ______ message to the source device.

    • Time Exceeded.
    • Echo Request.
    • Echo Reply.
    • Port Unreachable.

16. Which of the following statements are true about ICMP messages? (Multiple Choice)

    • ICMP messages can record time, including the original time, packet receiving time, and packet sending time.
    • ICMP messages are encapsulated in IP packets but not at the transport layer.
    • ICMP messages include error messages, control messages, request/response messages, and update messages.
    • ICMP does not support redirection.
    • ICMP messages cannot be used to detect a path’s MTU.

17. If a network’s broadcast address is 172.16.1.255, which of the following addresses can be the network address?

    • 172.16.2.0
    • 172.16.1.253
    • 172.16.1.128
    • 172.16.1.1

18. On the command line interface of Huawei AR routers, the role of the Save command is to Save the current system time.

    • TRUE
    • FALSE

19. Which of the following technologies is used to bind MAC addresses to interfaces on a switch?

    • SEP.
    • Port security.
    • ACL.
    • NAT.

20. In RSTP, a backup port can replace a faulty root port.

    • TRUE
    • FALSE
