H12-211 : HCIA Routing & Switching : Part 10

1. Two routers are connected via serial interfaces and the link-protocol is PPP, but the MRU of two serial interfaces are different, in PPP LCP negotiated stage, what will happen?

   • LCP negotiation will fail
   • Negotiation will use the smaller value

2. PPP is more secure than HDLC because PPP supports authentication protocols such as ( ). (Choose two)

   • PAP
   • MD5
   • CHAP
   • SSH

3. When both ends running PPP protocol detect that the physical link is active, the link state will transit from dead to establish.

   Which of the following protocols is used to negotiate the link parameters during this phase?

   • IP
   • DHCP
   • LCP
   • NCP

4. A serial interface of a Huawei router currently using HDLC needs to assign PPP as the encapsulation protocol.

   Which of the following commands is required to be configured at the serial interface view?

   • link-protocol ppp
   • encapsulation ppp
   • enable ppp
   • address ppp

5. When using VRP, which of the following commands is used to configure the PPP authentication method as PAP?

   • ppp pap
   • ppp authentication-pap
   • ppp authentication-mode pap
   • ppp pap-authentication

6. When configuring the PPP authentication method as PAP, which of the following operations are necessary? (Choose three)

   • Add the user name and password of the authenticated party to the local user list.
   • Configure the encapsulation type of the interface connected to the peer as PPP.
   • Configure PPP authentication method as CHAP.
   • On the authenticated party end, configure the user name and password that are sent to authenticator.

7. In the PPP protocol, which of the following encryption algorithms is used by CHAP?

   • DES
   • MD5
   • AES
   • None

8. What is the function of the “ip address ppp-negotiate” command?

   • Enables the function of requesting for an IP address from the peer device.
   • Enables the function of accepting the request for an IP address from the remote device.
   • Enables the function of statically allocating IP addresses to the peer.
   • None of the above.

9. Two routers have established a point-to-point network using PPP. The administrator has configured the routers to run OSPF in the same area with the same router ID, what behavior will occur as a result of the configuration?

   • The routers will build a neighbor relationship even though both routers are using the same router ID.
   • VRP will notify of a router ID conflict between the two routers.
   • The routers will build an adjacency even though both routers are using the same router ID.
   • The routers will not send hello packets to each other because they are using the same router ID.

10. The PPPoE session establishment process can be divided into which stages? (Choose all that apply.)

    • Discovery stage
    • DHCP stage
    • PPPoE Session stage
    • PPP connecting stage.

11. To establish multiple PPP point-to-point connections in the Ethernet network, a PPPoE server establishes connections with multiple PPPoE clients on one Ethernet port.

    How does PPPoE differentiate between each connection?

    • MAC address.
    • IP address and MAC address
    • MAC address and ppp-id
    • MAC address and session-id

12. When configuring a router as a PPPoE client, which configuration is not necessary?

    • Configuration of the dialer-rule
    • Configuration of the dialer interface
    • Configuration of an IP address on the dialer interface
    • Configuration of a password on the dialer interface

13. In the PPPoE discovery stage, the PPPoE server assigns a session-id to the PPPoE client in which packet?

    • PADI
    • PADO
    • PADR
    • PADS

14. Which command can be used to check the PPPoE client session status?

    • display ip interface brief
    • display current-configuration
    • display pppoe-client session packet
    • display pppoe-client session summary

15. [Huawei]rip 1
    [Huawei-rip-1]version 2

    Refer to the command output. An administrator wishes to configure RIP. Which other command needs to configured for RIP routes to be advertised?

    • import-route GigabitEthernet 0/0/1
    • network 192.168.1.0 0.0.0.255
    • network GigabitEthernet 0/0/1
    • network 192.168.1.0

16. A RIP router receives the routing update information from its neighbor.

    Which of the following statements regarding routing update are correct? (Choose three)

    • The received route that is not in the routing table will be added only when its hop count value is less than 16.
    • The received route that already exists in the routing table will be updated only when the next hop is the router’s neighbor and the cost value is smaller.
    • The received route that already exists in the routing table will be updated only when the next hop is not the router’s neighbor and the cost value is smaller.
    • The received route that already exists in the routing table will be updated only when the next hop is the router’s neighbor and the cost value has been changed.

17. Which of the following commands is used to display the current running state and configuration of RIP?

    • display protocol rip
    • show rip
    • display rip
    • display this rip

18. A user can view the information for the RIP protocol on a router. What does “Age time” in the returned result of the command mean?

    • The interval of updating an RIP packet
    • The aging time of an RIP route
    • The suppression time of an RIP route
    • The time spent on switching between RIP routes

19. After a command for displaying RIP route information is entered on a router, peer 192.168.1.2 on Serial1/0/0 is displayed in the returned result.

    What does 192.168.1.2 stand for?

    • Address of a RIP neighbor
    • Address of the port with the RIP protocol enabled
    • Next hop address of the RIP route
    • Transmission address of the RIP protocol

20. Refer to the debug output. Following configuration of R2, the administrator discovers that the behavior is not as expected and performs debugging. Based on the output from the debug, what is the source of the problem?

    

    • R2 has configured an ACL to block the route to network 1.0.0.0
    • R2 has enabled split horizon.
    • R1 is using authentication, however R2 is not.
    • R2 is operating using RIPv2, while R1 is using RIPv1.
