1. An administrator currently manages AR2200 devices in the network through a single password, however the company wishes to introduce another two administrators and provide unique user credentials and privilege levels for telnet access to the network devices.

   What action can be taken? (Choose three)

   • Configure three users under the AAA-view, and assign each a different password.

4. Refer to the configuration output. RTA has been configured using AAA as shown, and associated with the “huawei” domain. For users in the huawei domain, which authentication-scheme will be used?

   

   • au1
   • au2
   • au1 will be used. When au1 is deleted, users will use au2
   • au2 will be used. When au2 is deleted, users will use au1

5. A user accesses a server supporting AAA, for which the authorization mode on the AAA server has been configured using the command “authorization-mode hwtacacs if-authenticated”.

   Which of the following statements regarding this command are true? (Choose three).

   • If the hwtacacs server fails to respond, the user will be authenticated using local authentication.
   • If the hwtacacs server fails to respond, the user will be authenticated using remote authentication.
   • If the hwtacacs server fails to respond, the user will bypass authentication.

   • An interface ACL value ranges 1000-2000

8. Which of the following parameters is not used by Advanced ACL?

   • Source interface
   • Destination port number
   • Protocol number

9. Refer to the configuration output. Which of the following statements regarding ACL 2001 is correct?

   

   • Packets from network 10.0.1.0/24 network will be denied.
   • Packets from network 10.0.1.0/24 network will be permitted.
   • Packets destined for network 10.0.1.0/24 will be denied.
   • Packets destined for network 10.0.1.0/24 will be permitted.

10. Refer to the configuration output. A network administrator configured the ACL on router RTA, as shown.

    • The rule-number of the first rule is 1
    • The rule-number of the first rule is 5
    • The rule-number of the second rule is 2
    • The rule-number of the second rule is 10

11. Following a failure of services in the network, an administrator discovered that the configuration in one of the enterprise routers had been changed.

    What actions can be taken by the administrator to prevent further changes? (Choose three)

    • The administrator should limit access by setting the login privilege of users to 0.
    • The administrator should configure AAA to manage user authorization on the router.
    • The administrator should configure an ACL to allow only the administrator to manage the router.
    • The administrator should configure port-security on the router.

    •  Packets from network 20.1.1.0/24 network will be denied.
    • Packets from network 20.1.1.0/24 network will be permitted.
    • Packets destined for network 20.1.1.0/24 will be denied.
    • Packets destined for network 20.1.1.0/24 will be permitted.

13. Refer to the configuration output. Which of the following statements are correct regarding the configuration of the ACL on RTA? (Choose two).

    

    •  Packets from network 172.16.1.1/32 will be denied.
    • Packets from network 172.16.1.0/24 will be denied.
    • Packets from network 172.17.1.0/24 will be denied.

14. The network administrator wants to improve the performance of network transmission, what steps can the administrator take? (Choose two)

    

    • Change the work mode to full duplex of each end station.
    • Link the end stations together using a switch.
    • Change the work mode to half duplex of each end station.
