1. Which of the following user access authentication modes are supported In Huawel's CloudCampus Solution? (Select All that Apply)

802. IX authentication

MAC address authentication

Portal authentication

2. In a multicast solution, there must be reachable unlcast routes between multicast sources and receivers.

True

False

3. Which of the fallowings is not an IPv6 address type?

Multicast address

Unicast address

Broadcast address

Anycast address

4. 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)

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

The load balancing mechanism needs to be enabled. Then some STAs are steered from AP_1 to AP_2.

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

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

5. Which of the followings is an IPv6 multicast address?

2222::11

FF02::18C

FE80:: A

FC00::1

6. Satellite positioning can achieve high positioning accuracy in both indoor and outdoor scenarios.

True

False

7. Drag the reasons for AP onboarding failures on the left to the corresponding troubleshooting operations on the right.

8. Which of the following statements about fingerprint-based positioning technology are true? (Select All that Apply)

The positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information.

Terminals learn from each other to form a fingerprint library that can be shared.

APs collect surrounding environment information to form a fingerprint library.

The fingerprint map is obtained through onsite information collection.

9. With protocol trace, iMaster NCE-Campuslnsight displays protocol-level Interaction details at the phases for wireless users. (Enter the acronyms in capital letters.)

10. After the HTTP domain name is entered in a browser, the user Is not redirected to the Portal URL.

Which of the followings is the possible cause for this failure? (Select All that Apply)

The DNS server IP address is not added to the authentication-free rule.

The URL template is incorrectly configured.

HTTPS redirection is disabled.

The web server is incorrectly configured.

11. To which of the following scenarios is radio calibration applicable?

Enterprise office scenario

Rail transportation scenario

High-density scenario

WDS or mesh backhaul scenario

12. Which of the following statements about EAP relay and EAP termination are false? (Select All that apply)

A. In EAP termination mode, an access device encapsulates EAP packets sent by an 802. IX client Into RADIUS packets, without processing the data in the EAP packets.

B. In EAP relay mode, an access device extracts information from EAP packets, encapsulates the information into RADIUS packets, and sends the RADIUS packets to an authentication server.

C. In EAP termination mode, an access device extracts client authentication information from the EAP packets sent by a client and encapsulates the information using the standard RADIUS protocol. The access device supports only the EAP MD5-Challenge authentication method.

D. The EAP termination mode simplifies the processing on an access device and supports various authentication methods. However, this mode requires an authentication server to support EAP and have high processing capability.

13. In a VRRP HSB scenario, if the VRRP preemption delay is set to a small value, which of the following problems may occur after a master/backup switchover? (Select All that apply)

The batch backup process cannot be started.

A master/backup switchback is triggered too quickly.

Backup information is incomplete.

Service data on the master and backup WACs is lost.

14. In mesh networking, APs have different roles. Drag the AP roles on the left to the role descriptions on the right.

15. Drag the short-range wireless IoT technologies on the left to their corresponding descriptions on the right.

16. Which of the followings is not a roaming optimization solution?

Proactive roaming

Smart roaming

Fast roaming using PMK caching

802.11r roaming

17. Which of the following tools are commonly used for WLAN network planning, acceptance, or health evaluation? (Select All that Apply)

WLAN Planner

iMaster NCE-Campuslnsight

eDesk

CloudCampus APP

18. When a STA roams from API to AP2 at Layer 2, AP2 notifies its neighbors of from this STA is encapsulated in a tunnel and sent to API for forwarding.

True

False

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

In 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.

In 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.

In 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.

In 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.

20. Which of the following types of non-Wi-R devices can be identified by Huawei APs? (Select All that Apply)

Bluetooth device

ZigBee device

Game controller

2.4 GHz wireless video and audio transmitter
