Huawei H12-321 Online Questions & Answers

• Question 461:

  In the hot standby, the following statement about the HSB backup channel is wrong?

  A. The HSB backup channel between the primary and backup ACs is recommended to be connected separately to ensure high reliability.
  B. The HSB backup combination backup service is independent of each other, and the HSB backup group can work normally without binding.
  C. In the VRRP hot standby, the active/standby status of the HSB backup channel changes with the active/standby status of the VRRP.
  D. Under dual-link hot backup, the HSB channel has no active/standby status, only the data backup channel.
  B. The HSB backup combination backup service is independent of each other, and the HSB backup group can work normally without binding.

  B. Improves the overall performance of the wireless channels.
  C. Implements load balancing.
  D. Implements band steering.
  A. Improves service experience of the end users.
  B. Improves the overall performance of the wireless channels.

• Question 463:

  The zone surrounding the line of sight (LOS) is called the Fresnel zone, which is also called the RF LOS.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 464:

  Which of following statements about load balancing between the 2.4 GHz and 5 GHz radios are TRUE? (Multiple Choice)

  A. When the load difference on the 5 GHz and 2.4 GHz radios is smaller than the load balancing threshold, the AP instructs STAs to preferentially associate with the 5 GHz radio.
  B. When the bad on the 5 GHz and exceeds the load balancing threshold, the AP instructs STAs to preferentially associate with the 2.4 GHz radio.
  C. When the load on the 5 GHz exceeds the load balancing threshold, if a STA requests to associate with the 5 GHz radio, the AP will reject the association request until the STA associates with the 2.4 GHz radio.
  D. If the load difference threshold between the two radios is set to 10, the two radios are not load balanced only when there are ten more STAs associated with the 5 GHz radio than with the 2.4 GHz radio.
  A. When the load difference on the 5 GHz and 2.4 GHz radios is smaller than the load balancing threshold, the AP instructs STAs to preferentially associate with the 5 GHz radio.
  B. When the bad on the 5 GHz and exceeds the load balancing threshold, the AP instructs STAs to preferentially associate with the 2.4 GHz radio.

• Question 465:

  The typical networking of Huawei outdoor AP6510DN, AP6610DN, AP8030DN, and AP8130DN supports access point mode and bridge mode.

  A. Correct
  B. False
  A. Correct

• Question 466:

  What does the OU in the directory server stand for?

  A. User
  B. User group
  C. Organizational unit
  D. Domain

• Question 467:

  Which of the following statements about AP-based dynamic load balancing are TRUE? (Multiple Choice)

  A. Dynamic load balancing overcomes the limitation on the number of group members in static load balancing mode.
  B. The number of members in a dynamic load balancing group is the same as that in a static bad balancing group.
  C. Members can be automatically added to a dynamic load balancing group and can work on different frequency bands.
  D. Members can be automatically added to a dynamic load balancing group and must work on the same frequency band.
  A. Dynamic load balancing overcomes the limitation on the number of group members in static load balancing mode.

• Question 468:

  Globally, the AC runs the () and () algorithms based on the neighbor relationship, interference, and load information to generate the new transmit power and working channel of the AP.

  A. EDCA
  B. DCA
  C. CAC
  D. TPC
  B. DCA
  D. TPC

• Question 469:

  Which statement about smart roaming is FALSE?

  A. Smart roaming directs sticky STAs to APs with better signals, preventing STAs from sticking to the original AP.
  B. Smart roaming directs STAs to APs with better signals in a timely manner.
  C. Smart roaming can be implemented only when it is supported by STAs.
  D. Smart roaming enables the active probe function, so that APs can quickly collect neighbor information. Once a neighboring AP meets the condition, active roaming is triggered.
  C. Smart roaming can be implemented only when it is supported by STAs.

• Question 470:

  Regarding the establishment process of the backup CAPWAP link, the following statement is correct?

  A. The AP and the AC establish the primary tunnel and the backup tunnel at the same time.
  B. The AP sends a broadcast Discovery Request message to the standby AC.
  C. The Join message sent by the AP carries a custom message type, and the AC configuration has been sent.
  D. When the AC receives the Join message, the AC will skip the configuration and deliver the configuration.
  C. The Join message sent by the AP carries a custom message type, and the AC configuration has been sent.
  D. When the AC receives the Join message, the AC will skip the configuration and deliver the configuration.
