H12-224 : HCNP-R&S Fast Track (Huawei Certified Network Professional – Routing & Switching Fast Track) : Part 26

1. The system can perform ACL rule matching only based on the configuration order of rules.

   • True
   • False 

2. If different routing protocols run on different networks and these networks need to share routing information, route importing can be used.

   • True 
   • False

3. If the peer default-route-advertise command is used to advertise a default BGP route to peers, how will this operation affect the local BGP routing table?

   • An inactive default route will be generated in the local BGP routing table and this route will not be delivered to the IP routing table.
   • An active default route will be generated in the local BGP routing table and this route will be delivered to the IP routing table.
   • The local BGP routing table will not be affected and no default route will be generated in the local BGP routing table. 
   • A default route will be generated in the local BGP routing table and whether to deliver this route to the IP routing table depends on route selection results.

   • PIM-DM
   • F OSPF
   • F PIM-SM 

6. Which switching technology reduces the size of broadcast domain?

   • VLAN 
   • Trunk
   • RARP
   • STP

7. According to the OSI reference model, Layer 2 LAN switch operates at Q.

   • physical layer
   • data link layer 
   • network layer
   • application layer

8. Layer 3 switch has layer 2 capability as well as layer 3 routing capability.

   • True 
   • False

9. The default-route originate command in the RIP protocol is used to advertise a default RIP route to peers. By using this command, which of the following attributes can be set for the default route?

   • Tag
   • Cost 
   • Interface
   • Nexthop

10. Which of the following route selection tools is used in multiple routing protocols, can be configured with match conditions, and consists of if-match and apply clauses?

    • AS-path-filter
    • IP-p ref ix
    • C Route-policy 
    • Community-filter

11. You cannot set an aging time for the blacklist of the USG.

    • TRUE
    • FALSE 

12. Which of the following routes match this ACL filter? (Choose two.)

    

    •  1.1.1.1/32 
    • 1.1.2.1/32
    • 1.1.3.1/32 
    • 1.1.4.1/32

13. OSPF supports two authentication modes: area authentication and interface authentication.

    These two modes cannot be configured at the same time.

    • TRUE
    • FALSE

14. Which of the following statements is false?

    • A Router-LSA describes the local link state information of a router.
    • A Network-ISA describes the link state information of a broadcast network or an NBMA network segment.
    • A virtual link is a virtual adjacency in the backbone area (Area 0).
    • An AS-external-ISA describes the means to reach an ASBR. 

15. Which of the following statements about the Reverse Path Forwarding (RPF) mechanism are true? (Choose two.)

    • Multicast RPF does not depend on unicast routing.
    • All multicast protocols adopt the RPF mechanism.
    • A router discards the received multicast packets if the packets fail the RPF check.
    • The RPF mechanism has two functions: 1. It prevents multicast routing loops; 2. It avoids forwarding redundant multicast data packets.

16. What are the functions of route filtering? (Choose three.)

    • Avoids sub-optimal routes generated in route importing.
    • Avoids routing loops.
    • Affects route selection by changing route attributes.
    • Implements accurate route importing and controls route advertisement. 

17. The preceding information is generated after a router receives a Report message from group 225.0.0.1 through Ethernet 6/1/0.

    

    Which type of Report message will not be processed by the router?

    • IS_IN
    • ALLOW
    • BLOCK 
    • TO_IN
