Huawei Huawei Certification H12-321 Questions & Answers

• Question 521:

  After channel switching without service interruption is configured on an AP, when the AP channel needs to be switched, the AP will notify associated STAs in advance and switch to the new channel with STAs at the same time without interrupting services.

  A. TRUE

  B. FALSE

  Correct Answer: A

• Question 522:

  The following are the commands that can check whether the AP channel and transmit power enable the auto select function?

  A. [AC-wlan-view] display station ssid wlan-net

  B. [AC-wlan-view] display rrm-profile name profile-name

  C. [AC-wlan-view] display radio all

  D. [AC-wlan-view] display yap-profile name profile-name

  Correct Answer: B

• Question 523:

  In the WLAN network with WIDS enabled, what is the correct statement about the illegal device counter-function?

  A. When the AC determines that the device is a rogue AP, it notifies the monitoring AP of the rogue AP. The monitoring AP sends a broadcast deauthentication frame as an illegal AP.

  B. When the AC determines that the device is a rogue AP, it notifies the monitoring AP of the rogue AP. The monitoring AP sends a unicast deauthentication frame as an illegal AP.

  C. When the AC determines that the device is an illegal user terminal, the monitoring AP uses the BSSID or MAC address of the illegal device to send a unicast deauthentication frame.

  D. When the AC determines that the device is an illegal user terminal, the monitoring AP uses the BSSID or MAC address of the illegal device to send a broadcast deauthentication frame.

  Correct Answer: AC

• Question 524:

  The "5W" in "5W1H" in the Agile Controller function introduction refers to: Who is connected to the network; Where is the access from the network; When is the time access; Why is the access; What is the device access.

  A. Correct

  B. False

  Correct Answer: B

• Question 525:

  Which is the correct sequence for selecting a proper AP for 802.Ilk-capable STAs in smart roaming?

  1.

  Determine whether latency-sensitive services exist.

  2.

  Filter out APs that do not support load balancing.

  3.

  Filter out APs that do not meet the CAC requirement.

  4.

  Select the AP with the strongest signal strength as the target AP.

  5.

  Select APs meeting the difference threshold conditions.

  A. 1->2->3->4->5

  B. 1->3->4->5->2

  C. 1->5->3->2->4

  D. 1->4->5->3->2

  Correct Answer: C

• Question 526:

  Which statement about the Mesh network is FALSE?

  A. The Mesh network conforms to IEEE 802.11m.

  B. The Mesh network can both provide user access and forward wireless link signals.

  C. Multiple APs can form a Mesh network.

  D. Signals are routed from an AP to another within the Mesh network, and then transmitted to the wired network through the APs on a fixed path.

  Correct Answer: A

• Question 527:

  On an N+1 backup network, the AP establishes a CAPWAP link with the primary AC. The standby AC sends the primary discovery packets to the local device. The resource consumption of the AP is smaller than that of the dual link.

  A. Correct

  B. False

  Correct Answer: A

• Question 528:

  What is the correct description of load balancing between dual frequencies?

  A. When the load difference between the 5G and 2.4G radios is within the equalization threshold, the AP will direct the terminal to associate with the 5G.

  B. When the load on the 5G radio exceeds 2.4G at the equalization threshold, the AP will direct the terminal to associate with 2.4G.

  C. When the load on the 5G radio exceeds 2.4G in the equalization threshold, if the terminal is associated with 5G, the AP will always reject the terminal association until the terminal associates 2.4G.

  D. If the load balancing difference threshold is set to 10, it means that if the number of terminals on the 5G radio exceeds more than 10 of the 2.4G radio, the load between the two frequencies is considered to be unbalanced.

  Correct Answer: AB

• Question 529:

  On an intra-frequency Mesh network, two APs provide 200 Mbps bandwidth. Which is the average bandwidth if one more AP is added to the network?

  A. Up to 200 Mbps

  B. Up to 150 Mbps

  C. Up to 100 Mbps

  D. Up to 50 Mbps

  Correct Answer: C

• Question 530:

  Which of the following APs and STAs cannot communicate with each other? (Multiple Choice) A. API and STA1

  

  B. API and STA2

  C. AP2 and STA1

  D. AP2 and STA2

  Correct Answer: ACD
