In an HSB scenario, WIDS entries on the active WAC cannot be backed up to the standby WAC. After an active/standby switchover, WIDS entries are lost.

A.

TRUE

B.

FALSE

Which of the following statements about WLAN roaming and signal strength Is false?

A.

Smart roaming can be enabled on the WAC to help ST As roam and associate with APs with better signals.

B.

Generally, a STA roams when it detects that the signal strength is less than -75 dBm.

C.

STAs can roam between WACs in dual-link HSB mode.

D.

In most cases, the signal strength of a STA should range from -45 dBm to -65 dBm.

When calculating the number of APs, you can divide the total required bandwidth by the maximum bandwidth of a single AP.

A.

True

B.

False

As shown in the figure, STA_1 through STA_4 are associated with AP_1, and STA_5 is associated with AP_2. Assuming that the load balancing threshold is 2, the load difference threshold is 25%, and API and AP2 support a maximum of 10 STAs, which of the following statements are true? (Select All that Apply)

A.

The load percentage of AP_1 is 40%, and that of AP_2 is 10%.

B.

The load balancing mechanism needs to be enabled. Then some STAs are steered from AP_1 to AP__2.

C.

If load balancing is performed, the load percentage of AP_1 changes to 30%.

D.

The minimum load percentage is 10%, which is greater than the load difference threshold. Therefore, load balancing needs to be enabled.

In Huawei ' s smart roaming solution, which of the following factors does not need to be considered when the WAC selects a roaming target for a STA?

A.

AP Ioad

B.

APSNR

C.

AP transmit power

D.

STA access rate

Multicast addresses are Class D addresses, and can be used only as destination addresses but not source addresses of data packets.

A.

TRUE

B.

FALSE

What is the Campusinaght page shown in the figure?

A.

General dashboard

B.

Device dashboard

C.

Client dashboard

D.

Wi-Fi 6 dashboard

Which of the following statements is false about STA roaming tracks on a Huawei WAC?

A.

If the values of In Rx/Tx, In RSSI, Out Rx/Tx, and Out RSSI are low, the signal coverage in this area may be abnormal.

B.

If the values of In Rx/Tx, In RSSI, Out Rx/Tx, and Out RSSI are good, the signal coverage in this area is excessively dense.

C.

It is unreasonable that the value of Out RSSI is lower than the signal strength of the next associated AP.

D.

It is reasonable that the value of Out Rx/Tx is lower than the signal strength of the next associated AR

Inter-WAC roaming and intra-WLAN roaming are supported in dual-link HSB scenarios.

A.

TRUE

B.

FALSE

For multi-band APs, load balancing can be implemented among radios working on the same frequency band.

A.

TRUE

B.

FALSE

An engineer configures the user CAC function on a Huawei WAC as follows. Which of the following statements are true about these configurations?

A.

When the SNR of a STA exceeds 10 dB, the STA is allowed to go online.

B.

CAC based on the number of STAs is used.

C.

CAC based on terminal SNR is used.

D.

When the SNR of a STA is lower than 10 dB, the STA is allowed to go online.

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.

A Wi-Fi RFID tag is a signal generator manufactured by tag vendors to help locate the objects. Which of the following types of tags can be located by Huawei devices?

A.

Hotspot tag

B.

AeroScout tag

C.

Location tag

D.

Ekahau tag

In the Huawei CloudCampus Solution, when cloud managed devices register with iMaster NCE-Campus in DHCP option mode, which of the following options is used to obtain the IP address of iMaster NCE-Campus?

A.

Option 158

B.

Option 43

C.

Option 53

D.

Option 138

E.

Option 148

Which of the following statements are true about the site design in Huawei ' s CloudCampus Solution?

A.

It is recommended that network devices at the same physical location be planned into multiple sites. Different sites correspond to different services on the campus network.

B.

Each site can have a tenant administrator to independently manage and maintain its network, or an MSP administrator can be authorized to perform unified network management and O & M for all sites.

C.

An independent branch can be planned as a site based on the physical location, for example, a financial branch of a bank or a campus of a university.

D.

For a midsize campus network, do not plan too many sites. Otherwise, the interconnection between sites and site management will be complex.

Deploying user authentication points at the access layer achieves fine-grained permission management and high network security. However, as the network scale is rapidly expanding, problems arise, such as heavy configuration workloads and high O & M difficulties. To mitigate these problems, user authentication points can be moved upward from the access layer to the aggregation or core layer. In this way, authentication information across the entire network is centralized and the number of user authentication points is decreased, thereby reducing the configuration and maintenance workload.

A.

TRUE

B.

FALSE

On a WLAN, if PoE+ + power supply is used, the distance between a PoE switch and an AP can exceed 100 m.

A.

TRUE

B.

FALSE

Which of the following statements are true about wireless configuration synchronization in Huawei ' s WAC backup solutions?

A.

During batch backup of wireless configuration synchronization, public configurations can be performed on the master AC.

B.

Wireless configuration synchronization requires that the models and software versions of all WACs be the same.

C.

In wireless configuration synchronization, the source-ip and nas-ip are not allowed to be configured based on profiles.

D.

Wireless configuration synchronization can be used only with VRRP HSB or dual-link HSB; it cannot be used with dual-link cold backup or N+1 backup.

During Portal authentication of a terminal, an authorization failure message is displayed when the user opens the push page using a browser. Which of the following could cause this problem?

A.

The authentication device does not support the authorization attribute delivered by the authentication server.

B.

The terminal attempts to access an HTTPS website before passing the authentication.

C.

No Portal server template is bound to the VLANIF interface of the access control device.

D.

No DNS server is configured in the pre-authentication domain.

After built-in Portal authentication is configured on a Huawei WAC. the Portal authentication page can be displayed but Portal authentication cannot be performed. What are the possible causes?

A.

The AP version is outdated.

B.

The data forwarding mode is direct forwarding, and the WAC does not allow packets from service VLANs to pass through.

C.

The route configuration is incorrect. As a result, the STA cannot communicate with the built-in Portal server.

D.

The password entered on the STA is incorrect
