Which of the following methods are used in IPsec to ensure secure transmission of service data on the network through encryption and authentication?
- A. The receiver verifies the identity of the sender.
- B. The receiver rejects old or duplicate packets in order to prevent attacks initiated by malicious users who resend sniffed packets,
- C. The sender verifies the identity of the receiver.
- D. Data integrity is verified.
Answer: A,D
Explanation:
Explanation
IPsec uses authentication headers (AHs) and encapsulating security payloads (ESPs) to ensure secure transmission of service data on the network. AHs provide authentication and integrity verification for the sender and the receiver, while ESPs provide encryption and optional authentication for the data.

NEW QUESTION # 40
Drag the Huawei's wireless positioning solutions on the left to their corresponding features and application scenarios on the right.
Answer:
Explanation:
Explanation
According to the Huawei documents and resources, the features and application scenarios of the wireless positioning solutions are as follows:
Wi-Fi terminal positioning: Performs network-side positioning generally based on the RSSI, but provides low positioning accuracy. This method applies to scenarios such as precision marketing and customer flow analysis in shopping malls.
Bluetooth tag positioning: Runs based on the built-in Bluetooth module of an AP. The AP reports data to a positioning engine for location resolution. This positioning technology provides low positioning accuracy and applies to asset positioning and personnel positioning scenarios.
UWB positioning: Provides high positioning accuracy, and is applicable to scenarios that require high accuracy, such as intelligent manufacturing, warehousing logistics, and mechanical manufacturing.
Bluetooth terminal positioning: Runs based on the built-in Bluetooth module of an AP, which can be implemented on either the network side or terminal side.
Therefore, Wi-Fi terminal positioning - 3, Bluetooth tag positioning - 4, UWB positioning - 2, Bluetooth terminal positioning - 1 is the correct answer. References: :

- A. Echo
- B. Keepalive
- C. Join
- D. DTLS
Answer: A
Explanation:

NEW QUESTION # 42
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 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.
- 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 encapsulates EAP packets sent by an 802. IX client Into RADIUS packets, without processing the data in the EAP packets.
Answer: B,D
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:

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 # 44
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. If load balancing is performed, the load percentage of AP_1 changes to 30%.
- C. The load balancing mechanism needs to be enabled. Then some STAs are steered from AP_1 to AP__2.
- D. The load percentage of AP_1 is 40%, and that of AP_2 is 10%.
Answer: C,D
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.
