Free Huawei H12-351 Real Questions (page: 9)

The display sync-configuration compare command is executed on the backup WAC in HSB to check wireless configuration synchronization. Based on the command output, which of the following statements are true? (Select All that apply)

  1. This command is used to check whether the public configurations on two WACs are consistent after wireless configuration synchronization.
  2. The configuration of ssid-profile 2 exists on both the master and backup WACs.
  3. The configuration of vap-profile name 3 exists on the master WAC but not on the backup WA
  4. The configuration of vap-profile name 2 exists on the backup WAC but not on the master WAC.

Answer(s): A,C

Explanation:

The display sync-configuration compare command is used to check whether the public configurations on two WACs are consistent after wireless configuration synchronization. The command output shows the differences between the configurations on the master and backup WACs. In this case, the configuration of vap-profile name 3 exists on the master WAC but not on the backup WAC.

In a dual-link backup scenario, the active/standby link switchover mode is set to priority.
When the active link recovers, the AP detects that the original active link has a higher priority and triggers a switchback. How many Echo intervals does the AP wait for before switching back to the original primary WAC?

  1. 20
  2. 10
  3. 15
  4. 5

Answer(s): C

Explanation:

In a dual-link backup scenario, when the active link recovers, the AP waits for 15 Echo intervals before switching back to the original primary WAC. This prevents frequent link switchovers caused by unstable links.

In a dual-link HSB scenario, after an AP sets up CAPWAP links with the active and standby WACs, which of the following types of packets does the AP periodically send to the WACs to detect link status?

  1. DTLS
  2. Join
  3. Echo
  4. Keepalive

Answer(s): C

Explanation:

In a dual-link HSB scenario, after an AP sets up CAPWAP links with the active and standby WACs, the AP periodically sends Echo packets to the WACs to detect link status. The Echo packets are sent every 30 seconds by default.

Which of the followings is not a roaming optimization solution?

  1. Proactive roaming
  2. Smart roaming
  3. Fast roaming using PMK caching
  4. 802.11r roaming

Answer(s): B

Explanation:

Smart roaming is not a roaming optimization solution, but a feature that allows an AP to automatically adjust its transmit power based on signal strength and interference level. The other options are all roaming optimization solutions that can reduce roaming latency and packet loss.

DRAG DROP (Drag and Drop is not supported)
802. 11r fast roaming (over-the-air) is enabled on the WLAN shown in the figure. A STA roams from AP1 to AP2. Sort the steps in chronological order during the 802.11r fast roaming process between WACs.



  1. See Explanation section for answer.

Answer(s): A

Explanation:

According to the Huawei documents and resources, the chronological order during the 802.11r fast roaming process between WACs is as follows:

2.The STA accesses the network through API. This is the initial association process before roaming. 1.The STA initiates an 802.11 FT authentication request to AP2. This is the first step of the roaming process when the STA moves to a new AP.
3.AP2 starts the reassociation timer, and sends an 802.11 FT authentication response to the ST A. This is the second step of the roaming process when AP2 responds to the STA's request and sets a timer for reassociation.
4.The STA generates and installs a P TK based on the information contained in the response frame. This is the third step of the roaming process when the STA derives a new pairwise key for encryption.
5.The STA sends a reassociation request to AP2. This is the fourth step of the roaming process when the STA requests to reassociate with AP2.
6.AP2 generates and installs a PTK according to PMK-RI and information contained in the request frame. This is the fifth step of the roaming process when AP2 derives the same pairwise key as the STA.
7.After receiving the reassociation request, AP2 disables the reassociation timer, and then sends a reassociation reg onse to the STA. This is the sixth step of the roaming process when AP2 confirms the reassociation with the STA and stops the timer.
8.The STA receives the response frame of AP2. The roaming process is complete. This is the final step of the roaming process when the STA completes the handover to AP2. Therefore, 2, 1, 3, 4, 5, 6, 7, 8 is the correct answer.

question 35 is incorrect, the correct answer is c, it even states so: explanation: when a vm is infected with ransomware, you should not restore the vm to the infected vm. this is because the ransomware will still be present on the vm, and it will encrypt the files again. you should also not restore the vm to any vm within the companys subscription. this is because the ransomware could spread to other vms in the subscription. the best way to restore a vm that is infected with ransomware is to restore it to a new azure vm. this will ensure that the ransomware is not present on the new vm.
