NEW QUESTION # 35
Which of the following statements correctly arranges matching modes used by URL filtering in descending order of priority?
- A. Exact matching > Suffix matching > Prefix matching > Keyword matching
- B. Exact matching > Suffix matching > Keyword matching > Suffix matching
- C. Exact matching > Keyword matching > Suffix matching > Prefix matching
- D. Exact matching > Prefix matching > Suffix matching > Keyword matching
Answer: A
Explanation:
Explanation
URL filtering supports four matching modes: exact matching, suffix matching, prefix matching, and keyword matching. The priority order of these modes is as follows:
Exact matching: The highest priority. An exact match means that a URL entered by a user is exactly the same as a URL in a blacklist or whitelist.
Suffix matching: The second highest priority. A suffix match means that a URL entered by a user ends with a suffix in a blacklist or whitelist.
Prefix matching: The third highest priority. A prefix match means that a URL entered by a user starts with a prefix in a blacklist or whitelist.
Keyword matching: The lowest priority. A keyword match means that a URL entered by a user contains a keyword in a blacklist or whitelist.

NEW QUESTION # 37
After multicast-to-unicast conversion is enabled on an AP's air interface, which of the followings is the destination MAC address of multicast packets sent over the air interface?
- A. MAC address of the multicast source
- B. Multicast MAC address
- C. Broadcast MAC address
- D. MAC address of a STA
Answer: D
Explanation:
Explanation
After multicast-to-unicast conversion is enabled on an AP's air interface, the destination MAC address of multicast packets sent over the air interface is changed to the MAC address of a STA that has joined the multicast group. This improves the transmission efficiency and reliability of multicast packets.

NEW QUESTION # 38
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 periodically and proactively scans neighboring APs of STAs.
- C. STAs proactively report neighboring AP information.
- D. The AP listens to the Probe frames sent by 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 # 42
Which of the following advantages does BSS coloring provide in Wi-Fi 6? (Select All that Apply)
- A. More efficient channel use
- B. Higher concurrency in high-density scenarios
- C. Higher packet rate on the air interface
- D. Enhanced encryption on the air interface
Answer: A,B,C
Explanation:
Explanation
BSS coloring is a feature introduced in Wi-Fi 6 that assigns different colors to different BSSs to reduce co-channel interference. BSS coloring provides the following advantages:
Higher packet rate on the air interface: BSS coloring reduces collisions between packets from different BSSs on the same channel, improving packet transmission efficiency.
More efficient channel use: BSS coloring allows spatial reuse of channels by different BSSs, increasing channel utilization.
Higher concurrency in high-density scenarios: BSS coloring reduces interference among neighboring APs and improves network performance in high-density scenarios.

NEW QUESTION # 48
802. 11r fast roaming (over-the-air) is enabled on the WLAN shown in the figure. A STA roams from AP1 to AP2. Sort the steps in chronological order during the 802.11r fast roaming process between WACs.
Answer:
Explanation:
Explanation
According to the Huawei documents and resources, the chronological order during the 802.11r fast roaming process between WACs is as follows:
2.The STA accesses the network through API. This is the initial association process before roaming.
1.The STA initiates an 802.11 FT authentication request to AP2. This is the first step of the roaming process when the STA moves to a new AP.
3.AP2 starts the reassociation timer, and sends an 802.11 FT authentication response to the STA. This is the second step of the roaming process when AP2 responds to the STA's request and sets a timer for reassociation.
4.The STA generates and installs a P TK based on the information contained in the response frame. This is the third step of the roaming process when the STA derives a new pairwise key for encryption.
5.The STA sends a reassociation request to AP2. This is the fourth step of the roaming process when the STA requests to reassociate with AP2.
6.AP2 generates and installs a PTK according to PMK-RI and information contained in the request frame. This is the fifth step of the roaming process when AP2 derives the same pairwise key as the STA.
7.After receiving the reassociation request, AP2 disables the reassociation timer, and then sends a reassociation reg onse to the STA. This is the sixth step of the roaming process when AP2 confirms the reassociation with the STA and stops the timer.
8.The STA receives the response frame of AP2. The roaming process is complete. This is the final step of the roaming process when the STA completes the handover to AP2.
Therefore, 2, 1, 3, 4, 5, 6, 7, 8 is the correct answer. References:

NEW QUESTION # 51
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 balancing mechanism needs to be enabled. Then some STAs are steered from AP_1 to AP__2.
- C. The load percentage of AP_1 is 40%, and that of AP_2 is 10%.
- 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 # 52
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. APs collect surrounding environment information to form a fingerprint library.
- C. The fingerprint map is obtained through onsite information collection.
- D. The positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information.
Answer: C,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.

Which of the followings is not a roaming optimization solution?
- A. Smart roaming
- B. 802.11r roaming
- C. Proactive roaming
- D. Fast roaming using PMK caching
Answer: A
Explanation:
Explanation
Smart roaming is not a roaming optimization solution, but a feature that allows an AP to automatically adjust its transmit power based on signal strength and interference level. The other options are all roaming optimization solutions that can reduce roaming latency and packet loss.

- D. Although the static VXLAN tunnel mode supports the distributed gateway scenario, the configuration involves a heavy workload and is complex to adjust.
Answer: B,D
Explanation:
Explanation
B is false because a static VXLAN tunnel does not use any protocols on the control plane, saving device resources.
