Huawei H12-321 Online Questions & Answers

  • Question 121:

    The following is the correct command for creating a static load balancing group?

    A. [AC-wlan-view] regulatory-domain-profile name domain1
    B. [AC-wlan-view] air-scan-profile name wlan-airscan
    C. [AC-wlan-view] rrm-profile name profile-name
    D. [AC-wlan-view] sta-load-balance static-group name static-1

  • Question 122:

    Regarding the MP in the Mesh network, is the following description correct?

    A. MP nodes can also be called Mesh gateways.
    B. The MP node has a Portal function. Through this node, nodes inside the Mesh can communicate with the external network.
    C. MP nodes support automatic topology, automatic route discovery, packet forwarding, etc.
    D. MP nodes can provide both Mesh services and user access services.

  • Question 123:

    Although the Fresnel zone exists in all RF communication scenarios, its impact is mainly considered in which of the following communications?

    A. Outdoor point-to-point scene
    B. Indoor Mesh scene
    C. Indoor cellular coverage
    D. Outdoor cellular coverage

  • Question 124:

    The APs that enable the load balancing function do not need to be connected to the same AC, but the wireless terminal can scan the SSIDs of APs that are load balanced with each other.

    A. Correct
    B. False

  • Question 125:

    Which statements about reliability measurement are TRUE? (Multiple Choice)

    A. Generally, system reliability is determined by mean time between failure (MTBF) and mean time to repair (MTTR).
    B. MTBF refers to the average time (usually expressed in hours) from the fault occurrence time to the fault recovery time. A larger MTBF indicates a higher reliability.
    C. MTTR refers to the average time from the fault occurrence time to the fault recovery time.
    D. The formula for calculating the MTTR is as follows: MTTR= Fault detection time + Hardware replacement time + System initialization time + Link recovery time + Route convergence time + Forwarding recovery time A smaller MTTR indicates a higher reliability.

  • Question 126:

    In intelligent roaming, the following is the correct way to identify sticky terminals?

    A. When the results of three consecutive detection cycles are less than the set roaming threshold
    B. When the results of three consecutive detection cycles are greater than the set roaming threshold
    C. When the results of 6 consecutive detection cycles are less than the set roaming threshold
    D. When the results of 6 consecutive detection cycles are greater than the set roaming threshold

  • Question 127:

    As shown in the figure, four STAs (STA1 to STA4) are associated with API and STA5 is associated with AP2. The start threshold for load balancing is set to 5. API and AP2 each allow a maximum of 10 STAs and the load difference threshold is set to 10%. When STA6 sends an association request to API for the first time, which of the following statements is TRUE?

    A. API preferentially uses the load balancing algorithm for calculation and allows the association request from STA6.
    B. API preferentially uses the load difference threshold algorithm for calculation and allows the association request from STA6.
    C. API preferentially uses the load balancing algorithm for calculation and rejects the association request from STA6.
    D. API preferentially uses the load difference threshold algorithm for calculation and rejects the association request from STA6.

  • Question 128:

    As shown in the figure, a device needs to be added first during the configuration of the connection between the Agile Controller and AC6005. Which of the following addresses is the device IP address (172.16.1.2)?

    A. AC address that the AP obtains from Option43
    B. AP service VLAN gateway address
    C. IP address through which the switch connects to the Agile Controller
    D. IP address through which the AC connects to the Agile Controller

  • Question 129:

    Which of the following statements about rogue device identification on a WLAN with the WIDS function enabled are TRUE? (Multiple Choice)

    A. All ad-hoc deices are identified as rogue devices.
    B. APs not managed by the local AC are identified as rogue APs.
    C. STAs that do not go online through the local AC are identified as rogue STAs.
    D. If a STA does not go online through the local AC, the AC checks whether the STA is associated with an authorized AP.

  • Question 130:

    As shown in the figure, in a large enterprise WLAN network, the network administrator of the company recently discovered that the WLAN network traffic is abnormal, and the ping gateway has a delay or a large amount of packet loss. After excluding other possibilities, it is suspected that an illegal network attack has occurred. Which kind of illegal attack is the most likely?

    A. Flood attack
    B. Spoof attack
    C. Weak IV attack
    D. Violent cracking
