NEW QUESTION # 30
Drag the short-range wireless IoT technologies on the left to their corresponding descriptions on the right.

Answer:

Explanation:

Explanation
According to the Huawei documents and resources, the definitions of the short-range wireless IoT technologies are as follows:
ZigBee: IEEE 802.15.4-based wireless communication technology is a short-range, and low-power wireless communication technology that supports star, mesh, and hybrid networking.
Bluetooth: With the emergence of IoT industries such as smart wearables, smart home, and Internet of Vehicles, short-range communication technologies are attracting more and more developers.
REID: Its basic principle is to automatically identify objects based on the transmission characteristics of radio signals and space coupling (inductance or electromagnetic coupling) or radar reflection.
Wi-Fi: Wireless networking technology based on IEEE 802.11 is the most popular WLAN technology.
Therefore, ZigBee - 1, Bluetooth - 3, REID - 2, Wi-Fi - 4 is the correct answer. References: :

NEW QUESTION # 36
Which of the following statements about EAP relay and EAP termination are false? (Select All that apply)

A. 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.
B. 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.
C. 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.
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: B,C

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.

NEW QUESTION # 39
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: :

Explanation:
Explanation
The display sync-configuration compare command is used to check whether the public configurations on two WACs are consistent after wireless configuration synchronization. The command output shows the differences between the configurations on the master and backup WACs. In this case, the configuration of vap-profile name 3 exists on the master WAC but not on the backup WAC.

NEW QUESTION # 42
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)

A. Service data on the master and backup WACs is lost.
B. A master/backup switchback is triggered too quickly.
C. Backup information is incomplete.
D. The batch backup process cannot be started.

Answer: B,C

Explanation:
Explanation
According to the Huawei documents and resources, the VRRP preemption delay is the time that an AC waits before preempting another AC with a lower priority. If the VRRP preemption delay is set to a small value, the following problems may occur after a master/backup switchover:
B: A master/backup switchback is triggered too quickly. If the master AC recovers soon after a switchover, it may preempt the backup AC again and become the master AC. This may cause frequent switchovers and affect network stability C: Backup information is incomplete. If the backup AC takes over services from the master AC too quickly, it may not have received all the data synchronized from the master AC through HSB. This may cause service interruption or data loss Therefore, B and C are the correct answers. References:
