Begin to Test:

1. Regarding the establishment process of the standby CAPWAP link, which of the following statements is correct? (Multiple choice)

AP and AC establish the primary tunnel and backup tunnel at the same time and complete the configuration delivery

Ability to amplify electromagnetic waves

The antenna's ability to collect or emit electromagnetic waves in all directions is strong or weak

Question 8 of 25

9. The lobe width is a very important parameter commonly used in directional antennas. It refers to the width of the angle formed by the antenna's radiation pattern below the peak () dB.

Question 9 of 25

10. The port number of the control message of the CAPWAP tunnel protocol is ().

1645

1646

5246

5247

Question 10 of 25

11. Among the following priority queues, the () queue has the highest default priority.

AC-BE

AC-VI

AC-VO

AC-BK

Question 11 of 25

12. Which of the following description of TKIP encryption is wrong?

The length of IV used in TKIP encryption is 24 bits

TKIP encryption uses the same encryption algorithm as WEP encryption

The motivation for developing TKIP encryption is to upgrade the security of the old WEP hardware

TKIP encryption adds the mechanism of key generation, management and transmission

Question 12 of 25

13. If the terminal supports both 5GHz and 2.4GHz functions, the AP can be configured to control this terminal to preferentially access 5GHz.

True

False

Question 13 of 25

14. WEP encryption data algorithm adopts () algorithm.

RC4

AES

CCMP

Asymmetric encryption

Question 14 of 25

15. AAA is a management framework, which is more commonly used () protocol to achieve.

RADIUS

CAPWAP

802.11a/b/g/n

802.1X

Question 15 of 25

16. Which statement about power adjustment is wrong?

The AP's transmit power determines the coverage area of its radio frequency signal. The greater the AP's power, the greater the coverage area.

Global tuning algorithms mainly include dynamic channel adjustment algorithm TPC and transmit power control algorithm DCA

The traditional radio frequency power control method only statically sets the transmit power to the maximum value and purely pursues signal coverage, but excessive power may cause unnecessary interference to other wireless devices

When dynamically adjusting power, it is very necessary to choose an optimal power that can balance coverage and signal quality

Question 16 of 25

17. In the 802.11s routing protocol, which of the following is not a routing management frame?

RANN

PREQ

PREP

PS-Poll

Question 17 of 25

18. Provide WLAN Internet services in public places such as banks and airports, and users can access the Internet after searching for the SSID. However, if there is a private AP and an SSID that is the same as or similar to the legal SSID is set, the user may access the private AP by mistake when searching for the SSID, which may pose a security risk.
In order to solve this problem, what function can be used?

WIDS device countermeasure function

WIDS attack detection + WIDS blacklist function

WIDS attack detection + WIDS equipment countermeasures

Configure SSID counterfeit identification rules + WIDS device countermeasures

Question 18 of 25

19. Which of the following terminal access is most suitable for MAC authentication?

Port 1813 on the server is occupied

The authorization rule matching is to deny access

Question 21 of 25

FIFO model

DiffServ model

Question 22 of 25

23. When PPPoE authentication is used in WLAN, it has nothing to do with the authentication encryption adopted by the WLAN itself.

True

False

Question 23 of 25

24. After enabling user CAC, it is set to limit the number of users based on channel utilization. Assuming that the current channel utilization exceeds the configured threshold, the AP will not only reject the association of new terminals, but also kick existing terminals Line until the channel utilization is below the threshold.
