MAC authentication is an authentication method that controls user access rights based on the interface and terminal MAC address. Which of the following descriptions about MAC authentication are correct? (Multiple choice)
- A . By default, the user name used for MAC authentication is the terminal’s MAC address, and the password is the last six digits of the terminal’s MAC address (in hexadecimal).
- B . In MAC authentication, there are two ways to process user passwords: PAP and CHAP.
- C . The terminal does not need to install any client software, nor does it need to manually enter the username and password. It is suitable for dumb terminal access authentication scenarios
- D . The MAC authentication system consists of three components: terminal, access device and MAC authentication server
Which of the following options are the business demand characteristics of high-density venues? (Multiple choice)
- A . Various business access control types
- B . There are many user terminals and the types are concentrated
- C . The user only connects to a certain area and does not need to consider roaming
- D . Large number of user registration management, centralized user authentication
Initially, if you use a wireless connection to an AP, which of the following IP addresses can be used by default to log in and manage the FITAP?
- A . 192.168.1.1
- B . 169.254.2.1
- C . 192.168.2.1
- D . 169.254.1.1
In a WLAN network, how many spatial streams can a single radio support at most according to the 802.11ac and 802.11ax protocols?
- A . 6
- B . 10
- C . 8
- D . 12
As shown in the figure, which of the following descriptions of the CampusInsight interface is correct? 
- A . Engineers are checking the service topology
- B . Engineers checking performance experience
- C . Engineer looking at the wireless user journey
- D . Engineers are checking the health of wireless users
When designing indoor AP coverage, the number of obstacles that the signal passes through should be minimized. It is not recommended to penetrate 240m thick brick walls, concrete walls or metal walls for coverage.
- A . True
- B . False
Which of the following descriptions is correct about the relationship between power measurement units? (Multiple choice)
- A . If the power of A is 26dBm and the power of B is 20dBm, then it can be said that A is 6dBm greater than B.
- B . dB represents the relative value of power, 0dB represents the original power
- C . -3dBm power is equivalent to one fifth of the original power
- D . 10dBm is equivalent to ten times the original power
When two APs work on the same channel, there may be interference and delay when sending and receiving data at the same time, which will reduce network performance. Therefore, it is recommended to plan different working channels that do not interfere with each other between APs with overlapping coverage areas.
- A . True
- B . False
Which of the following working modes does the AP’s wired interface have? (Multiple choice)
- A . Auto mode
- B . root mode
- C . endpoint mode
- D . middle mode
Which of the following statements about the requirements for confirming on-site environmental information during WLAN on-site survey is correct? (Multiple choice)
- A . Confirm whether the site is completely consistent with the architectural drawings. Mark out the inconsistent areas, take photos as much as possible, and mark the room numbers on the site in the drawings.
- B . Take as many photos of the scene as possible indoors; pay special attention to the equipment installation location, overall coverage area, internal building structure, and new obstacles. For outdoor coverage, pay attention only to the obstacles between the AP and the coverage area.
- C . When surveying indoors, refer to the drawings to distinguish the types of obstacles, mark the actual location of each type of obstacle, mark obstacles of different materials with different colors, and test their 2.4G and 5G attenuation values
- D . When surveying indoors, be sure to mark out other obstacles that are not shown on the drawings but affect the coverage effect, such as load-bearing columns, partitions added during decoration, ceilings and other large objects
- E . Outdoors, you need to pay attention to the height and obstruction range of obstacles on site. For irregular obstacles (such as trees, etc.), try to take photos to record them.
