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

NEW QUESTION # 58
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 minimum load percentage is 10%, which is greater than the load difference threshold. Therefore, load balancing needs to be enabled.
- B. The load percentage of AP_1 is 40%, and that of AP_2 is 10%.
- C. The load balancing mechanism needs to be enabled. Then some STAs are steered from AP_1 to AP__2.
- D. If load balancing is performed, the load percentage of AP_1 changes to 30%.
Answer: B,C
Explanation:
Explanation
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.

NEW QUESTION # 60
Which of the followings is an IPv6 multicast address?
- A. FC00::1
- B. FE80:: A
- C. 2222::11
- D. FF02::18C
Answer: D

NEW QUESTION # 64
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. 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 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:
