12. <Huawei>
    Warning: Auto-Config is working. Before configuring the device, stop Auto-Config. If you perform configurations when Auto-Config is running, the DHCP, routing, DNS, and VTY configurations will be lost. Do you want to stop Auto-Config? [y/n]:

    When an administrator first initializes the router, a warning is displayed. Which statement regarding this warning is correct?

    • If Auto-Config is required, the administrator should select ‘y’.
    • If Auto-Config is not required, the administrator should select ‘n’, for which subsequent configuration of the DHCP server, routing, DNS server and VTY user configuration is lost.
    • When a device is started for the first time, the Auto-Config function is active.
    • When a device is started for the first time, the Auto-Config function is inactive.

13. An AR2200 router in the company network cannot boot. In order to resolve this, the administrator wishes to update the VRP software.

    What should he/she do?

    • The administrator should use a console cable to connect the router and host, and directly upgrade the device.
    • The administrator should use FTP to transfer the VRP software, by configuring the AR2200 router as an FTP client.
    • The administrator should use DHCP to boot the AR2200, and then use the AR2200 router as a TFTP client to download the VRP software from the server.
    • The administrator should use the telnet command on the client to remote access the device, and upgrade the VRP software.

14. <Huawei>

    Warning: Auto-Config is working. Before configuring the device, stop Auto-Config. If you perform configurations when Auto-Config is running, the DHCP, routing, DNS, and VTY configurations will be lost. Do you want to stop Auto-Config? [y/n]:

    What are the possible reasons for this? (Choose three).

    • Another DHCP server exists in the network and is allocating IP addresses to hosts that happen to be within a closer proximity than the authorized DHCP server.
    • The hosts were unable to discover a DHCP server and therefore generated their own address in the 169.254.0.0 address range.
