Question No. 1

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)

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

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

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

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

Show Answer

Correct Answer: A, B

The load percentage of an AP is calculated by dividing the number of associated STAs by the maximum number of STAs supported by the AP. In this case, the load percentage of AP_1 is 4/10 = 40%, and that of AP_2 is 1/10 = 10%. The load balancing mechanism needs to be enabled to balance the load between AP_1 and AP_2. Then some STAs are steered from AP_1 to AP_2 based on the load balancing threshold and the load difference threshold.

Question No. 2

Which of the following configurations may cause ST As to experience a slow Internet connection? (Select All that Apply)

AQoS CAR is configured in the traffic profile.

BRadio 1 of APs is disabled.

CTKIP encryption is configured, causing a low link setup rate.

DRate limiting is configured in the SSID profile.

Show Answer

Correct Answer: A, C, D

B is false because disabling radio 1 of APs does not affect the Internet connection speed of STAs that use radio 2.

Question No. 3

Which of the followings is not a roaming optimization solution?

AProactive roaming

BSmart roaming

CFast roaming using PMK caching

D802.11r roaming

Show Answer

Correct Answer: B

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.

Question No. 4

Which of the following statements are true about the WLAN site survey In different typical scenarios? (Select All that Apply)

AIn a classroom scenario. If the walls are made of reinforced concrete, the signal attenuation Is high. In this case, you are advised to test the attenuation during the site survey. Additionally, pay attention to the locations of ELV rooms in the teaching building.

BIn an office scenario, the load-bearing columns and partitions affect the signal coverage. If an integrated ceiling is used, deploy APs near maintenance entrances. If a metal ceiling is used, mount APs on the ceiling or wall.

CIn a ward-round scenario, high requirements are posed on the coverage field strength, roaming effect, and bandwidth. Determine the interference of medical equipment and the areas where Wi-Fi signals are not allowed.

DIn a stadium scenario, the onsite environment is complex and cabling is difficult. Therefore, confirm with the property management company about ELV rooms and cabling. If the transmission distance is too long, consider deploying more switches. During the survey, focus on the interference between APs and AP mounting modes.

Show Answer

Correct Answer: A, B, C, D

Only: All statements are true about the WLAN site survey in different typical scenarios.

Question No. 5

Either of the two APs that have established a mesh connection can send a Mesh Peering Close frame to the other AP to tear down the

mesh connection.

ATrue

BFalse

Show Answer

Correct Answer: A

A mesh connection can be torn down by either of the two APs that have established it by sending a Mesh Peering Close frame to the other AP. This frame indicates that the sender no longer wants to maintain the mesh connection.
