1.The undo command can be used in the CLI of a Huawei device to restore default settings, disable
functions, or delete configurations.
Which of the following are correct undo commands? (Select all that apply)
A. <HUAWEI> system-view
[HUAWEI] undo system-view
<HUAWEI>
B. [HUAWEI] interface GE 1/0/1
[HUAWEI-GE1/0/1] ip address 10.12.1.1 24
[HUAWEI-GE1/0/1] undo ip address
C. [HUAWEI] interface GE 1/0/1
[HUAWEI-GE1/0/1] undo portswitch
[HUAWEI-GE1/0/1]
D. [HUAWEI] sysname TEST
[TEST] undo sysname
[HUAWEI]
Answer: B, C, D
Explanation:
On Huawei devices, the undo command is used to remove a previously applied configuration, disable a
function, or restore a parameter to its default state.
In option B, undo ip address is a valid interface-view command that removes the IP address configured on
the interface.
In option C, undo portswitch is also a valid interface command on switch interfaces that converts a Layer
2 interface into a Layer 3 interface when supported by the device.
In option D, undo sysname restores the device name to the default hostname, which is valid in system
view.
Option A is incorrect because system-view is a command used to enter system view from user view, but
undo system-view is not a valid command for exiting that view. Exiting system view is done with
commands such as quit, return, or by using shortcut keys. This question checks the understanding that
undo only applies to configurable features and parameters, not to view-switching commands in the CLI
hierarchy.
2.In the figure, a web client sends an HTTP request to a web server, and the router in between performs
operations on the HTTP request.
Which of the following statements are false about the router’s operations? (Select all that apply)
A. The router encapsulates a new destination IP address before sending the data.
B. The router removes the data frame header and checks the destination IP address.
