H12-211 : HCIA Routing & Switching : Part 09

1. Which of the following steps are necessary to configure OSPF on a Huawei router? (Choose three)

   • Configuration of a router ID
   • Enabling of an OSPF process
   • Specifying an OSPF area
   • Configuration of the network segments within each area

2. Which of the following statements regarding the DR in an OSPF network are correct? (Choose two)

   • There must be at least one DR in an OSPF area.
   • A DR must be elected among the routers through the negotiations that are defined by OSPF protocol.
   • Only the router with highest priority will be elected as DR.
   • Only NBMA or Broadcast networks need to elect DR.

3. Which of the following VRP commands can be used to enter area 0 view? (Choose two)

   • [Huawei]ospf area 0
   • [Huawei-ospf-1]area 0
   • [Huawei-ospf-1]area 0.0.0.0
   • [Huawei-ospf-1]area 0 enable

4. Which of the following commands is used to display the OSPF neighbor relationship establishment?

   • display ospf neighbor
   • display ospf brief
   • display ospf peer
   • display ospf interface

5. With what kind of routers does a DRother router exchange link state information and route information? (Choose two)

   • DR
   • BDR
   • DRother
   • All OSPF neighbors

6. An OSPF area is a collection of a group of routers and networks. OSPF defines that routers that have the same ( ) belong to the same OSPF area.

   • neighbors
   • LSDB
   • LSA
   • adjacency

7. Which of the following statements about router IDs are true? (Choose two)

   • The routers contained in the same LSDB have the same router ID.
   • Each router in an OSPF network must have a unique router ID.
   • Two routers in different OSPF areas can have the same router ID.
   • A router ID is expressed in a 32-bit dotted decimal format.

8. OSPF allows for “multiple” processes. By default, OSPF selects a process whose number is ( ).

   • 0
   • 1
   • 10
   • 100

9. In a network supporting IPv6, OSPF no longer supports which feature?

   • multiple areas
   • Router-ID
   • authentication
   • multicast updates

10. Two routers are configured with OSPFv3. OSPFv3 is enabled on all interfaces of each router.

    Which of the following is true in the event that the network administrator does not configure a Router-ID?

    • The IP address of the loopback 0 interface will be used as the router ID.
    • The IP address of the loopback 1 interface will be used as the router ID.
    • The IP address of interface G0/0/0 will be used as the router ID.
    • No router ID will be assigned to the router.

11. Refer to the graphic. Which of the following statements is correct when this router forwards the packet to the destination host 9.1.4.5?

    

    • The router selects the first entry to match the destination address of the packet because the preference of OSPF is higher than the preference of RIP.
    • The router selects the second entry to match the destination address of the packet because the cost of RIP is lower than that of OSPF.
    • The router selects the second entry to match the destination address of the packet because the outgoing interface is an Ethernet interface. The forwarding speed of an Ethernet interface is faster than the forwarding speed of a serial interface
    • The router selects the second entry to match the destination address of the packet because the router will match the most specific address.

12. According to the default value of route preference on the VRP platform, which of the following represent the correct sequence for direct route, static route, RIP and OSPF if they are listed from high preference to low preference?

    • Direct, Static, RIP, OSPF
    • Direct, OSPF, Static, RIP
    • Direct, OSPF, RIP, Static
    • Direct, RIP, Static, OSPF

13. A router has learned two routes for the same network with the same prefix. One route has been learned via OSPF with a metric of 4882, while the other route has been learned via RIPv2 with a metric of 4.

    Which route (s) will be found in the routing table?

    • The RIPv2 route.
    • The OSPF and RIPv2 routes.
    • The OSPF route.
    • Neither of these routes will be found in the routing table.

14. Assume that the router has learnt the best route to the same destination by using RIP, OSPF and Static Route respectively. By default, the Huawei router will select the route learnt via ( ) as the best route.

    • RIP
    • OSPF
    • RIPv2
    • Static route

15. After checking the OSPF neighbor state, the administrator discovers that the router has established a TWOWAY state with the peering router.

    What can be understood from this information? (Choose two)

    • The routers are configured using the same process ID
    • The routers are configured using the same area ID
    • The routers are configured using wrong router ID
    • The routers are considered DROthers in a broadcast network

16. What functions does a Hello packet of OSPF implement? (Choose two)

    • Neighbor discovery
    • Deletion of unreachable neighbors
    • Maintaining of neighbor relationships
    • Negotiation of parameters among adjacent ports

17. Two routers are connected through serial interfaces and support PPP encapsulation.

    Which parameters must be negotiated to establish the PPP connection? (Choose three).

    • MRU
    • Authentication password
    • Magic-Number
    • IP address

18. What are the three protocol components defined by PPP? (Choose three).

    • Data encapsulation.
    • LCP
    • NCP
    • IPCP

19. Two routers are connected via serial interfaces, for which the link-protocol is PPP. The network administrator wishes to configure PPP authentication to improve security on this link.

    Which PPP authentication method provides a more secure solution?

    • CHAP
    • PAP
    • MD5
    • SSH

20. If PPP authentication fails, which type of packet will be sent to the authenticated peer by the authenticator?

    • Authenticate-Ack
    • Authenticate-Nak
    • Authenticate-Reject
    • Authenticate-Reply
