If all indicators of the AP are always off, it is possible that the indicator light is currently configured to be turned off. It is recommended to configure the undoledoff command on the wireless controller to turn on the indicator light and then reset the indicator light status.
- A . True
- B . False
When using the terminal dial test tool to evaluate network quality, the exported dial test report not only gives a clear evaluation of various network indicators, but also provides troubleshooting directions for possible problems.
- A . True
- B . False
Use terminal dialing test tools to evaluate the quality of customer networks. After the test is completed, export the test report. The test results show that the Internet uplink performance and Internet downlink performance test results are poor. Internet uplink performance: average 5Mbps, failure rate 100%; Internet downlink performance: average 21Mlbps, failure rate 100%.
In response to the above problems, which of the following optimization and troubleshooting measures are recommended for customers? (Multiple choice)
- A . Determine the terminal wireless network card capabilities and whether it only supports low-speed protocols
- B . Confirm the current air interface wireless interference situation. If there is a high interference problem, optimize the air interface.
- C . Check whether there are bottlenecks on the wired side, such as speed limits, network congestion, etc.
- D . Log in to the wireless controller to check whether the dynamic speed limit is turned off. If not, turn off the function.
As shown in the figure, this is the customer’s demand for a conference room. Based on these parameters, how many APs are needed to meet the capacity requirements of the conference room?
- A . 5
- B . 6
- C . 3
- D . 7
In the WLAN network optimization solution, which of the following descriptions about networking optimization are correct? (Multiple choice)
- A . For medium and large enterprises, since they have a large number of APs, different service VLANs can be used when setting different SSIDs.
- B . It is recommended to separate the AP/WAC management address from the user business address for easy management and control
- C . In coverage scenarios with high user mobility, it is recommended to shorten the address pool lease period so that addresses can be recovered in a timely manner.
- D . It is recommended that AP avoid setting both management VLAN and user service VLAN to 1 to prevent loops.
In a WLAN network, the same VAP template can reference both the STA whitelist and the STA blacklist, thereby allowing legitimate users to access the WLAN network and denying illegitimate users access to the WLAN network.
- A . True
- B . False
Which of the following statements about AP installation location is correct? (Multiple choice)
- A . For aesthetic reasons, APs can be placed on the ceiling.
- B . The material of the ceiling is generally very thin, and the impact on the coverage can be ignored
- C . When wall-mounting or installing under the ceiling, drilling may be required. During the survey, please confirm with the property management whether this is feasible.
- D . If the site has an integral suspended ceiling, the AP should be placed near the maintenance port as much as possible.
Wireless communication allows only one device to send messages on a channel at the same time. Wireless terminals are in a competitive relationship. In order to prevent bandwidth resources from being monopolized by a certain terminal, user-based speed limits can be configured to solve the problem. For example, it is recommended to limit the terminal speed in multi-user and high-density scenarios.
The configuration for enabling user rate limiting on the wireless controller is as follows. Which of the following configuration descriptions is wrong? [WAC-wlan-view] traffic-profile name wlan-traffic
[WAC-wlan-traffic-prof-wlan-traffic] rate-limit client up 2048
[WAC-wlan-traffic-prof-wlan-traffic] rate-limit client down 3072
[WAC-wlan-traffic-prof-wlan-traffic] quit
- A . The total uplink rate of all terminals under a VAP is limited to 5 Mbps
- B . The uplink rate of each terminal is limited to 2 Mbps
- C . The above speed limit configuration is effective for all terminals under the VAP bound to the traffic template.
- D . The downlink rate of each terminal is limited to 3 Mbps
In WLAN networks, in addition to signal attenuation affecting the receiver’s recognition of wireless signals, interference and noise will also have an impact to a certain extent. Both interference and noise are related to the environment and do not change with the source signal.
- A . True
- B . False
The engineer deployed a wireless environment in the customer’s existing network. After completing the AP online and service configuration on the wireless controller, he used the terminal to associate the signal and found that the corresponding SSID could not be searched.
Which of the following is NOT the cause of this problem?
- A . AP power supply is insufficient
- B . The AP’s radio frequencies are all turned off
- C . The test terminal does not support the currently configured country code
- D . The AP’s working channel is a radar channel and needs to be silent for a period of time
