Huawei H12-321 HCIP-WLAN-CEWA Exam Practice Test Instant Access

Question 1

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.

ACorrect

BFalse

Answer : A

Question 2

Regarding the NAC statement, what is wrong with the following description?

ANAC (Network Admission Control) is called network admission control.

BNAC is an end-to-end security architecture that includes 802.1x, MAC and Portal authentication.

CNAC access terminal equipment, if you need Portal authentication, you need to install client software.

DNAC access terminals use 802.1x authentication, you need to install client software.

Answer : C

Question 3

If you are roaming between two APs, which of the following must be met?

AThe same security policy

BSame SSID

CThe same data forwarding mode

DThe same service VLAN

Answer : A, B, C

Question 4

The following description of load balancing is correct?

AThe same radio of an AP can only be added to a load balancing group.

BIf it is a multi-frequency AP, the load balancing between the radios in the same frequency band on the AP is implemented.

CA dual-band AP can be added to two load balancing groups at the same time.

DLimited members in each load balancing group, supporting up to 32 members

Answer : A, B, C

Question 5

The general antenna is reversible, that is, the same antenna can be used as a transmitting antenna or as a receiving antenn

a. The same characteristic parameters of the same antenna as transmitting or receiving are the same.

ACorrect

BFalse

Answer : A

Question 6

Which of the following measures are beneficial to guide wireless terminals to preferentially associate 5G bands?

A5G radio configuration transmission power is higher than 2.4G 3-8dB

BFor the terminal to send a probe request to probe the AP, the AP preferentially responds to the probe on the 5G, and responds to the probe on the 2.4G after responding several times on the 5G.

CIf the terminal initiates association with the 2.4G radio, the AP refuses to associate, and the association is allowed only after the number of rejections reaches a certain threshold. For the association on the 5G radio, the AP immediately allows the association.

DConfigure the rate of the beacon on the 5G to be higher than the 2.4G radio. The beacon period is greater than the 2.4G radio. The number of probe retransmissions is less than 2.4G.

Answer : A, B, C

Question 7

The following is a statement about WLAN hot backup, what is wrong?

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

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

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

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