NEW QUESTION 102
Which of the following descriptions of the room sub-system is correct? (Multiple choice)
- A. The AP installation location should ensure that the Ethernet is reachable (less than 100 meters from the access switch), and local power supply should be guaranteed if there is no POE switch.
- B. It is generally not recommended to add a WLAN power amplifier behind the AP
- C. According to the actual measurement experience, in the indoor distributed system, the wlan signal power of the antenna port is ideally about 10dBm, and the minimum is not less than 5dBm. Generally, the transmit power of the wlan AP junction point is at least not less than 3G/GSM/CDMA signal power.
- D. limited by the number of users; a single AP is connected to the number of antennas should not exceed 15.
- E. AP junction point must be at the second stage of active equipment (mainly dry amplifier), because active equipment cannot pass wlan signals, and all wireless components of the feed-free system (including power splitters, cables, jumpers, etc.), must be able to support the WLAN frequency band (2.4GHZ~2.4835Ghz), and the attenuation control point is within a certain range.
Answer: A,B,C,D,E

The following description of the antenna, which is correct? (Multiple choice)
- A. The choice of antenna should meet the requirements of the coverage scenario, not the larger the gain, the better
- B. The greater the antenna gain, the smaller the coverage angle
- C. The greater the gain of the antenna, the higher the convergence of the signal
- D. The larger the gain of the antenna, the better, using a large gain antenna can get more transmit power
Answer: A,B,C
NEW QUESTION 109
Regarding the method and logic of thin AP P data forwarding, which of the following statements are correct? (Multiple choice)
- A. In the option43 mode of layer three registration, the AP will first send a broadcast discovery message after obtaining an IP address, and will try to send a unicast discovery request message when it does not receive the corresponding AC.
- B. If you manually configure the AC's IP address directly on the AP, you can also complete the three-layer registration. However, this method requires initial configuration and is troublesome to implement, so it is not recommended.
- C. In the three-layer registration Option43 mode, after the AP obtains the IP address, it will directly send a Discovery unicast discovery request message to the AC address specified by Option43
- D. In DNS mode, you only need to specify the relevant domain name on the DNS server to map to the AC IP address, and no special configuration by the DHCP server is required.
Answer: B,C
