NO.72 The following is an incorrect way to refer to AP access control (Select 2 Answers).  By default, the access control mode of the AP to the AC is not authenticated.  By configuring the AP in the offline state, authentication is required to automatically access the AP.  The configuration whitelist can be authenticated based on the MAC or authenticated based on the SN.  If the AP access control adopts MAC authentication, the AP outside the MAC authentication list can also be online after being manually confirmed. NO.73 For the CAPWAP protocol, the following description is wrong.  Transmission protocol between AC and thin AP  Transmission protocol between thin AP and wireless client  Developed by the CAPWAP Working Group The development of the  CAPWAP protocol draws on the useful features of other protocols. NO.74 TKIP encryption is higher than WEP encryption in security, which of the following are correct? (Multiple choice)  adopt longer IV  joined the key distribution mechanism, instead of using a single key  adopt the more complicated the encryption algorithm  adopt the stronger data validation algorithm NO.75 Point-to-point wireless bridge can be used to connect two separate network located in different sites, in wireless backhaul connection, Root AP and Leaf AP should set different channels.  True  False NO.76 For outdoor long-distance point-to-point backhaul, the antenna of should be selected.  High gain, small lobe width  High gain, large lobe width  Omnidirectional  Low gain, large lobe width NO.77 Which of the following options is not the main purpose of roaming?  avoid roaming in the process of certification time is too long lead to packet loss and even business interruption  ensure that the user authorization information remains the same  ensure that the user IP address remains the same  ensure that the user’s network rate unchanged NO.78 How many subcarriers can 802.11a use to transmit data in 20M mode?  48  52  54  56 NO.79 What is the China WLAN security mandatory standard?  WiFi  WAPI  WLAN  WiMax NO.80 The modulation methods adopted by DSSS are BPSK and QPSK respectively.  TRUE  FALSE NO.81 The gain of antenna A is 11dBi, and the gain of antenna B is 8dBi. It can be said that antenna A has a larger gain than antenna B.  3dB  3dBi  3dBd  Uncertain NO.82 Which channels are not overlapped with each other in 802.11b protocol? (Multiple Choice)  1  3  6  11 NO.83 For the AC6605, the following commands can be used to check whether the AP is online.  display ap online all  display ap all  display ap-type all  dispay ap-run-info all NO.84 Engineer A deployed a large number of AP during the project implementation process. It was found that there were only 16 AP on AP, and it was not fixed 16. The following reasons which is correct?  AP authentication mode is mac-auth or sn-auth, which causes some AP failed to go online.  Some POE switches fail and AP can’t go online.  License number reaches the upper limit  AP failure can’t be online NO.85 In TKIP encryption, which bit is the length of IV vector?  12  24  48  64 NO.86 In Huawei eSight, the method of adding WLAN devices includes (Select 3 Answers).  Add manually  Add automatically  Add in batches  Add script NO.87 WEP encryption’ data algorithm using which algorithm?  RC4  AES  CCMP  asymmetric encryption NO.88 Configure the authentication mode of the AP.What are the authentication modes supported by the AP (Select 3 Answers)?  mac-auth  sn-auth  no-auth  mac-sn-auth NO.89 IEEE is the standard organization responsible for the use of wireless frequencies in the United States.  True  False NO.90 If the coverage area has a higher demand on WLAN capacity, it should consider the construction mode of ().  distribute system indoor  distribute system outdoor  Indoor installation  Indoor agile distributed system  Loading … Huawei H12-311 Dumps PDF Are going to be The Best Score: https://www.examslabs.com/Huawei/HCIA-WLAN/best-H12-311-exam-dumps.html --------------------------------------------------- Images: https://blog.examslabs.com/wp-content/plugins/watu/loading.gif https://blog.examslabs.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2022-09-07 10:40:27 Post date GMT: 2022-09-07 10:40:27 Post modified date: 2022-09-07 10:40:27 Post modified date GMT: 2022-09-07 10:40:27
