Huawei Certified Network Professional - Wireless Local Area Network- Constructing Enterprise WLAN Architecture - H12-321 Free Exam Questions

A. peer-ap mac

B. mesh-whitelist-profile

C. ap-system-profile

D. radio radio-id

A. The global radio calibration algorithm includes the Dynamic Channel Allocation (DCA) algorithm and Transmit Power Control (IPC) algorithm.

B. During dynamic power adjustment, it is necessary to select an optimal power to balance the signal coverage with system capacity.

C. An AP's transmit power determines its radio coverage area. APs with higher power have larger coverage areas.

D. A traditional method to control the radio power is to set the transmit power to the maximum value to maximize the radio coverage area. However, a high transmit power may cause interference to other wireless devices.

A. When configuring VRRP hot backup, you can set the priority of the VRRP to determine the priority of the AC.

B. In dual-link hot backup, the primary and backup ACs can be backed up through Layer 3 interworking on different Layer 2 networks.

C. In dual-link hot backup, load balancing can be implemented by configuring the priorities of the active and standby ACs to be consistent.

D. Configure VRRP hot backup. The active and standby ACs must be in the same Layer 2 network.

A. Calculate the load percentage of all members in the equilibrium group and get the minimum value.

B. If the STA continues to send an association request to the AP after rejecting the association, although the number of repetitions is greater than the set maximum number of rejection associations, the STA is eventually rejected.

C. The load percentage is calculated by the formula (the number of users associated with the current RF / the maximum number of associated users supported by the current RF) x 100%

D. Measure whether the allowed access is the difference between the percentage of the load of the AP radio that is pre-joined by the STA and the minimum value of the load percentage of all members, and compare this difference with the set load difference threshold (configured through the command line)

A. MAP is a special form of MPP

B. Any Mesh Point that supports AP functions can provide access functions for STAs.

C. MAP is a special form of MP

D. MAP is usually used to connect terminals

A. There is AP1 information on AC2, and AP1 is in standby state in AC2.

B. There is STA1 information on AC2, and the status of STA1 is unauthenticated.

C. There is no STA1 information on AC2.

D. There is AP1 information on AC2, and AP1 is in the normal state of AC2.

A. The AD server uses the LDAP directory service protocol.

B. The AD server uses the AD directory service protocol.

C. The AD server is a dedicated directory server for the Windows Server.

D. LDAP can be installed on the Windows Server.

A. If the interference caused by a neighbor is smaller than the lower interference threshold, the algorithm determines whether to reduce the transmit power according to the difference between the interference caused by the neighbor and the lower interference threshold.

B. The core of the Dynamic Channel Allocation (DCA) algorithm is the exhaustion and iteration algorithms, which list all possible AP-Channel combinations and choose the optimal combination.

C. Interference specified by the lower interference threshold is low, and within the allowed range. Two neighbor APs cannot detect interference from each other and can send packets simultaneously.

D. The Transmit Power Control (TPC) algorithm aims to choose a proper transmit power which can meet coverage requirements of an AP.

A. A-B-C-D

A. The source IP address and source port number of the local end are inconsistent with the destination IP address and destination port number of the peer.

B. The priority values of the two ACs are consistent.

C. The TCP channel sent by the active and standby mechanism packets is not established.

D. The number of retransmissions of the primary and backup service packets is different from the retransmission interval.
