NEW QUESTION # 32
In Huawei's smart roaming solution, which of the following methods can be used by a WAC to discover and maintain neighboring AP entries of STAs? (Select All that Apply)
- A. The WAC obtains such entries using 802. 11v.
- B. The AP listens to the Probe frames sent by STAs.
- C. STAs proactively report neighboring AP information.
- D. The AP periodically and proactively scans neighboring APs of STAs.
Answer: B,D
Explanation:
Explanation
In Huawei's smart roaming solution, the WAC can discover and maintain neighboring AP entries of STAs by using two methods: passive listening and active scanning. Passive listening means that the AP listens to the Probe frames sent by STAs and reports them to the WAC. Active scanning means that the AP periodically and proactively scans neighboring APs of STAs and reports them to the WAC.

NEW QUESTION # 33
Drag the reasons for AP onboarding failures on the left to the corresponding troubleshooting operations on the right.
Answer:
Explanation:
Explanation
According to the Huawei documents and resources, the troubleshooting operations for the AP onboarding failures are as follows:
APS fail to be authenticated by the WAC: Whitelist the APS. The WAC can authenticate APs based on their MAC addresses or SNs. If an AP is not whitelisted on the WAC, it cannot be authenticated and onboarded.
License resources on the WAC are insufficient: Expand the license capacity. The WAC can manage a limited number of APs based on its license. If the license resources are insufficient, some APs cannot be onboarded.
APS fail to obtain IP addresses: Check the DHCP server. The APs need to obtain IP addresses from a DHCP server before they can communicate with the WAC. If the DHCP server is not configured or reachable, the APs cannot obtain IP addresses and onboard.
APS fail to ping the WAC: Check the network between the WAC and APS. The APs need to ping the WAC to discover its IP address and establish a CAPWAP tunnel. If there is a network problem between the WAC and APs, such as incorrect VLAN configuration or firewall blocking, the APs cannot ping the WAC and onboard.
Therefore, APS fail to be authenticated by the WAC - c, License resources on the WAC are insufficient - b, APS fail to obtain IP addresses - d, APS fail to ping the WAC - a is the correct answer. References: :

NEW QUESTION # 36
Which of the following items is not involved in the HLD phase?
- A. Capacity planning
- B. Deployment planning
- C. Network design
- D. AP position planning
Answer: D
Explanation:
Explanation
According to the Huawei documents and resources, the HLD phase is the high-level design phase of a WLAN project. It involves the following items:
Capacity planning: Determines the number and types of devices required for the WLAN network based on the customer's requirements and network scale.
Network design: Designs the network topology, IP addressing scheme, VLAN division, security policies, and other network parameters for the WLAN network.
Deployment planning: Plans the deployment sequence, schedule, resources, and risks for the WLAN project.
AP position planning is not involved in the HLD phase. It is part of the LLD phase, which is the low-level design phase of a WLAN project. It involves the detailed design of AP positions, antenna types, channel allocation, power adjustment, and other wireless parameters for the WLAN network. Therefore, C is the correct answer.

NEW QUESTION # 37
Which of the following statements are true about data collection of IMaster NCE-Campuslnslght? (Select All that Apply)
- A. iMaster NCE-Campuslnsight uses telemetry to Implement efficient data collection.
- B. Calculated data can be displayed on iMaster NCE-Campuslnsight only after a license Is loaded on the device management page.
- C. To collect data from WLAN devices, ensure that WACs can communicate with the southbound IP address of iMaster NCE-Campuslnsight. APs do not need to communicate with the southbound IP address of iMaster NCE-Campuslnsight.
- D. The UTC time of iMaster NCE-Campuslnsight must be the same as that of its managed devices.

Explanation:
Explanation
B is false because calculated data can be displayed on iMaster NCE-CampusInsight without loading a license on the device management page. The license only affects the number of devices that can be managed by iMaster NCE-CampusInsight.
D is false because the UTC time of iMaster NCE-CampusInsight does not need to be the same as that of its managed devices. However, it is recommended that they use the same time zone to avoid confusion.

NEW QUESTION # 43
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.
- A. False
- B. True
Answer: A
Explanation:
Explanation
When a STA roams from AP1 to AP2 at Layer 2, AP2 notifies its neighbors of the MAC address learned from this STA. The MAC address is not encapsulated in a tunnel and sent to AP1 for forwarding. Instead, AP1 deletes the MAC address entry of the STA and releases the IP address lease.

NEW QUESTION # 46
Which of the following statements about fingerprint-based positioning technology are true? (Select All that Apply)
- A. Terminals learn from each other to form a fingerprint library that can be shared.
- B. The positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information.
- C. APs collect surrounding environment information to form a fingerprint library.
- D. The fingerprint map is obtained through onsite information collection.
Answer: B,D
Explanation:
Explanation
Fingerprint-based positioning technology is a method that uses the signal strength or phase difference of wireless signals to locate objects. There are two types of fingerprint-based positioning technology: virtual fingerprint-based positioning and real fingerprint-based positioning. In virtual fingerprint-based positioning, the positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information. In real fingerprint-based positioning, the fingerprint map is obtained through onsite information collection.

NEW QUESTION # 47
Which of the following statements about EAP relay and EAP termination are false? (Select All that apply)
- A. 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.
- B. 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.
- C. 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.
- D. 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.
Answer: A,B
Explanation:
Explanation
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. This statement is false because in EAP termination mode, an access device extracts information from EAP packets, encapsulates the information into RADIUS packets, and sends the RADIUS packets to an authentication server2.
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. This statement is false because it describes the EAP relay mode, not the EAP termination mode2.
Therefore, A and D are the correct answers. References: 2:
