H12-224 : HCNP-R&S Fast Track (Huawei Certified Network Professional – Routing & Switching Fast Track) : Part 18

1. What is the maximum bits of a Class C address can be used for subnet?

   • 6
   • 8
   • 12
   • 14

2. Which of the following statements about the setup of a BFD session are true? (Choose three.)

   • A BFD session can be set up in either static or dynamic mode.
   • A static BFD session is set up by manually configuring BFD session parameters and delivering requests for setting up a BFD session. BFD session parameters include the local and remote discriminators.
   • A dynamic BFD session is set up by dynamically allocating local discriminators.
   • Static and dynamic BFD sessions are not differentiated.

3. Which of the following statements about the Smart Link group is false?

   • A Smart Link group has two interfaces at most. The two interfaces if configured are an active interface and a standby interface.
   • Among the two interfaces in a Smart Link group, one is in the active state and the other one in the standby state in normal situations.
   • When the active interface goes down, the Smart Link group automatically blocks it and changes the status of the standby interface to active.
   • When the active interface recovers from a fault, traffic will be switched back to it immediately. 

4. Different from a Stub area, an NSSA supports Type-5 LSAs.

   • True
   • False 

5. Which of the following are characteristics of a high availability network? (Choose two.)

   • Faults seldom occur.
   • Services can be quickly restored when a fault occurs.
   • Faults never occur.
   • Services can only be manually restored when a fault occurs.

6. Which of the following statements about NSSA commands is false?

   • If the default-route-advertise parameter is set, a Type-7 default route is generated. 
   • The no-import-route parameter is used to prevent the importing of AS external routes in the form of Type-7 LSAs into an NSSA.
   • The no-summary parameter is used to prevent the advertisement of Type-3 and Type-4 LSAs in an area.
   • The set-n-bit parameter indicates that an N-bit will be set in a DD packet.

7. Which of the following Statement is false?

   

   • The OSPF Router ID of the local router is 1.1.1.1.
   • The OSPF Router ID of the neighbor is 2.2.2.2.
   • The OSPF Router ID of the neighbor is larger and thus the neighbor acts as a DR. 
   • The local router acts as slave.

8. One class B network 155.16.0.0, the mask is 255.255.255.192. then subnet quantity available is ( ), the host quantity in every subnet at most is ()

   • 512126
   • 102464
   • 102462 
   • 256254
   • 192254

9. The NBMA mode requires all the routers in the network to be fully connected; otherwise, it does not function.

   • True
   • False 

10. Which of the following statements about the BFD echo function are true? (Choose three.)

    • The local system sends a series of BFD Echo packets, and the remote system loops the packets back through its forwarding channel. 
    • If the local system receives several consecutive Echo packets, it advertises a session Down event.
    • The echo function can work together with the asynchronous or demand detection mode.
    • The echo function can take the place of fault detection by sending BFD control packets.

11. Which of the following statements about VLSM characteristics are true? (Choose two.)

    • VLSM supports both IPv4 and IPv6.
    • VLSM supports overlapped address ranges.
    • VLSM provides more proper route summarization information in the routing table.
    • VLSM allows a subnet to be divided into smaller subnets.

12. Which of the following statements about the BFD demand mode are true? (Choose two.)

    • The local system periodically sends BFD control packets, and the remote system detects the BFD control packets sent from the local system.
    • The local system detects the BFD control packets sent by itself.
    • If one system does not receive any BFD packets from its peer within a detection period, it advertises a session Down event.
    • Each system confirms its connections with other systems in a particular method. After a BFD session is set up, BFD control packets are no longer sent. 

13. Different types of networks cannot establish an adjacency in the Full state.

    • True
    • False 

14. A Class C network needs to be divided into five subnets and each subnet needs to contain a maximum of 20 hosts. Which of the following subnet masks is used?

    • 255.255.255.192
    • 255.255.255.240
    • 255.255.255.224 
    • 255.255.255.248

15. How many Class C networks does the summarized route 192.168.134.0/22 cover?

    • 2
    • 4
    • 8
    • 16

16. When two routers exchange LSDB information by exchanging DD packets, a master/slave relationship is established between the two routers. The router with a larger router ID is the master.

    • True 
    • False

17. The subnet mask of a class A address is 255.255.240.0, how many bits are used to divide subnet?

    • 4
    • 5
    • 9
    • 12

18. In VRP 5.7, which of the following dynamic protocols support GR? (Choose three.)

    • MPLS LDP/RSVP
    • IS-IS/OSPF
    • BGP
    • MSTP
