Question 71

First of all, the multi-frequency combiner must be able to support the required working frequency band, and the closer its passband frequency is to the working frequency of the wireless system, the better, and there is no redundant passband, so as to ensure the best effect; secondly, it must be used for a combined with filtering function, the isolation between ports is generally greater than 80dB, which can minimize the interference between different systems.

A.False

B.True

Question 72

Which of the following are the shortcomings of FAT AP? (Multiple choice)

A.FAT AP software is stored on the AP, and the software needs to be upgraded one by one when the software is upgraded, which requires a lot of maintenance work

B.Each FAT AP supports individual configuration, and building a large network has a huge workload for AP configuration

C.No wireless controller required, can work independently

D.The configuration of the FAT AP is saved on the AP, and the loss of the AP device can cause the leakage of the system configuration

Question 73

Which statement about wireless link switch control parameters are correct? (Multiple choice)

A.Link Saturation RSSI: When the signal strength of the opposite end exceeds the threshold, the signal reception may be saturated, resulting in failure to demodulate and link failure. At this time, link switching will be performed immediately

B.Link Switch Margin: The backup link is switched to the signal threshold of the main link. When the RSSI of the backup link is compared with the RSSI of the main link, when the signal difference is greater than the Link Switch Margin value, the backup link is switched to the main link

C.Link Hold Time: In order to prevent frequent switching of the main link, when the backup link is switched to the main link, the shortest time the main link is kept.

D.Link Hold RSSI: The minimum signal strength required to establish and maintain a link

E.Link-maximum-number: The number of MESH links established between the vehicle MR and the trackside, including the main link and the backup link

Question 74

Regarding the local forwarding function of FIT AP, which of the following statements are correct? (Multiple choice)

A.After the local forwarding function is enabled, the control flow and data flow adopt different processing methods. The control flow of managing AP and users is processed by AC, while user data forwarding is directly processed by AP

B.The administrator can configure the user data accessed from the specified SSID to be forwarded locally, but cannot be configured to access from the specified vlan User data for local forwarding

C.After the local forwarding function is enabled, the AP directly forwards the client's data, and the AC is no longer involved in data forwarding, which greatly reduces the burden on the AC

D.To realize the local forwarding function, a configuration file needs to be issued to the AP. The function of the file is to connect the wired side of the AP to the Ethernet interface type is configured as a trunk type, and allows management VLAN and business VLAN data to pass

E.All FIT APs currently support local forwarding

Question 75

For coverage planning for areas with a large radius and few concurrent users, which of the following statement is correct? (Multiple choice)

A.deployed in such a multi-area AP, need to consider the AP divided between the channels, AP used between poor channel deployment with less interference, for example, when deploying three APs, the channels of AP1, AP2, and AP3 can be set to 1, 6 and 11 respectively

B.This type of area is the main WLAN indoor application place, such as comprehensive function area, hotel guest room, etc., this type of area can be divided into small areas according to rooms, walls, columns, etc., as a combination of multiple small radius and fewer users

C.Such areas can be covered by low-power APs respectively, and the coverage method can be based on the coverage of areas with small radius and few users. It is necessary to pay attention to the isolation of each AP frequency point during coverage.

D.This type of area can be covered by an indoor distributed system, using the sky of the original wireless network (such as PHS, CDMA, etc.) The feeder system combines WLAN systems to achieve the effect of one AP covering a larger area.
