Question 121

Which of the following statements about the use of the debugging command is correct?

A.Use some specific debugging commands only when looking for certain types of traffic or failures and narrowing down the cause of the failure to a possible range, which on the one hand can reduce the impact of debugging commands on device performance, and on the other hand On the one hand, it reduces the output of a lot of useless information, which is conducive to more rapid fault location

B.Since the debug command occupies different system resources in each output direction, depending on the network load, we should use the convenience ( info-center console debugging command) and low resource consumption ( info-center log buffer debugging command) ) to balance

C.The debugging command should be used to find faults, not to monitor normal network operation

D.Try to use it when the network usage is low or when there are few network users to reduce the impact of debugging commands on the system

E.Do not use the debugging command lightly without fully grasping the working process of the debugging command and the information it provides

Question 122

Which of the following statements about antenna gain is correct?

A.The higher the gain of the antenna, the higher the degree of signal convergence

B.The higher the gain of the antenna, the better, using the antenna with large gain can obtain greater transmit power

C.The selection of the antenna should meet the requirements of the coverage scenario, not the bigger the gain, the better

D.The larger the antenna gain, the smaller the coverage angle

Question 123

Question 124

Wireless Controller Supports Stacked Devices (Multiple Choice)
The networking of IRF is created to meet the market demands of high reliability and high performance. Currently, only mid-to-high-end wireless controller products support IRF features.
Among the newly developed products of V7, the supported products include WX3500H series, WX5500H series, WBC series and wireless controller card series supporting IRF feature;
In products upgraded from V5 to V7, only WX5500E series and wireless card series support IRF feature.

A.Cassette devices are directly connected for stacking

B.stacking devices in the same frame

C.Boxed devices are stacked across devices

D.Cross-frame device stacking

Question 125

Regarding the wireless client roaming among multiple H3C wireless controllers, which of the following statements is true ______

A.When the user associates with any AC (HA) in the roaming group for the first time, the terminal will obtain the service, after that, the authorization information of the terminal will be synchronized to other ACs in the roaming group by the HA

B.When the user goes offline, FA will notify HA, and HA will notify other AC users in the roaming group to go offline

C.To realize client roaming between multiple wireless controllers, multiple wireless controllers need to be configured into the same roaming group, and the wireless controllers will automatically negotiate and establish an I ACT P tunnel as the wireless xxx

D.When roaming occurs, the user's newly accessed AC will be called the user's FA. When roaming occurs again, the user's HA remains unchanged, and the FA is replaced with the AC that was accessed last time

E.After a wireless terminal associates with a wireless controller for the first time, the wireless controller is the HA of the terminal. After roaming occurs, the newly associated controller
