In WLAN networks, antenna gain refers to the ratio of the radiated power density of the antenna in a specified direction to the radiated power density of the reference antenna (usually an ideal radiation point source) when the input power is the same.
Which of the following are the main units for expressing antenna gain? (Multiple choice)
- A . dB
- B . dBi
- C . dBm
- D . dBd
Which of the following are common faults in WLAN networks? (Multiple choice)
- A . The terminal fails to associate with the wireless signal
- B . The terminal cannot access the Internet after connecting to the network
- C . The terminal frequently disconnects
- D . Device CPU utilization is too high
Which of the following descriptions about Mesh backhaul are correct? (Multiple choice)
- A . The Mesh backhaul channel should choose a 5G channel with better air interface quality.
- B . It is recommended to use different channels for Mesh backhaul and coverage channels
- C . Ensure line of sight on the Mesh backhaul path and avoid obstacles
- D . Avoid using DFS channels for Mesh backhaul channels
In VRRP hot standby networking, after hot standby is configured on the wireless controller, the master-slave channel cannot be established, and the information on the master device cannot be backed up to the backup device normally, resulting in abnormal hot standby function.
Which of the following may be the causes of this problem? (Multiple choice)
- A . The active and standby WAC models are inconsistent
- B . The primary and backup channel parameter configurations do not match
- C . The source IP address and source port number of the local end are inconsistent with the destination IP address and destination port number of the remote end.
- D . The number of retransmissions and retransmission intervals of the primary and backup service messages are inconsistent
In Mesh networking, which of the following are necessary conditions for two adjacent APs to establish a Mesh connection? (Multiple choice)
- A . Same security policy
- B . Same Mesh ID
- C . Same channel
- D . The MAC addresses of neighboring APs need to be added to the Mesh whitelist strategy
In wireless network coverage optimization, unreasonable AP point deployment will affect the coverage effect, so it is necessary to replace the AP point and redeploy it. Which of the following descriptions about AP point selection are correct? (Multiple choice)
- A . In office scenarios, the AP should be installed at a distance from the load-bearing column to avoid excessive signal attenuation.
- B . When one AP covers a room, it is recommended to install the AP in the center of the room.
- C . It is recommended to deploy APs separately at intersections or corners to ensure signal coverage continuity
- D . For continuous multi-room coverage scenarios, if the wall structure is concrete, it is recommended that one AP cover one room.
The WLAN network of a certain enterprise headquarters adopts WAC+FIT AP networking mode, and the branch adopts Leader AP networking mode. Now the headquarters is required to uniformly manage the WLAN network of the branch, so the Leader AP of the branch needs to be switched to FIT AP.
- A . True
- B . False
When optimizing wireless network planning, it is also necessary to collect wired network data, including network architecture, key equipment configuration and operating status, etc.
- A . True
- B . False
After a customer completed the wireless network deployment on the existing network, all APs worked on the same channel, causing serious interference. Automatic radio frequency adjustment was enabled on the wireless controller, and the current tuning progress was checked through the command line. The following is the result.
So which option is wrong in the description of the following command line echo?
- A . The sensitivity of RF tuning is medium
- B . 2.4G tuned channel set is 1.6, 11
- C . The current tuning has ended
- D . The configured tuning mode is manual mode
