To which of the following scenarios is radio calibration applicable?
- A. Enterprise office scenario
- B. High-density scenario
- C. Rail transportation scenario
- D. WDS or mesh backhaul scenario
Answer: B
Explanation:
Explanation
Radio calibration is applicable to high-density scenarios where a large number of users access the network simultaneously and require high bandwidth, such as stadiums, exhibition halls, and conference centers. Radio calibration can improve user experience by increasing the frequency bandwidth for high-load APs.

NEW QUESTION # 15
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: https://support.huawei.com/enterprise/en/doc

NEW QUESTION # 17
Which of the following advantages does BSS coloring provide in Wi-Fi 6? (Select All that Apply)
- A. Higher concurrency in high-density scenarios
- B. Higher packet rate on the air interface
- C. Enhanced encryption on the air interface
- D. More efficient channel use
Answer: A,B,D
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 # 18
Which of the following statements correctly arranges matching modes used by URL filtering in descending order of priority?
- A. Exact matching > Keyword matching > Suffix matching > Prefix matching
- B. Exact matching > Suffix matching > Prefix matching > Keyword matching
- C. Exact matching > Suffix matching > Keyword matching > Suffix matching
- D. Exact matching > Prefix matching > Suffix matching > Keyword matching
Answer: B
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 # 19
Which of the following statements about attack defense is true?
- A. Defense against flood attacks can be used to defend against Ping of Death attacks.
- B. Attack defense allows APs to analyze the contents and behaviors of incoming packets on ports to determine whether packets have attack characteristics. The APs then take defense measures on the packets that have attack characteristics.
- C. Fragmentation attack defense enables a device to detect packet fragments in real time and discard or rate-limit them to protect the device.
- D. Attack defense can defend against spoofing packet attacks, malformed packet attacks, fragmentation attacks, and flood attacks.
Answer: B
Explanation:
Explanation
Attack defense is a feature that allows APs to analyze the contents and behaviors of incoming packets on ports to determine whether packets have attack characteristics. The APs then take defense measures on the packets that have attack characteristics, such as discarding them or limiting their rate. Attack defense can defend against spoofing packet attacks, malformed packet attacks, fragmentation attacks, and flood attacks.

NEW QUESTION # 22
Which of the following statements about WLAN roaming and signal strength Is false?
- A. STAs can roam between WACs in dual-link HSB mode.
- B. In most cases, the signal strength of a STA should range from -45 dBm to -65 dBm.
- C. Generally, a STA roams when it detects that the signal strength is less than -75 dBm.
- D. Smart roaming can be enabled on the WAC to help ST As roam and associate with APs with better signals.
Answer: C
Explanation:
B is false because generally, a STA roams when it detects that the signal strength is less than -70 dBm or -65 dBm, not -75 dBm.

Which of the followings is not a roaming optimization solution?
- A. Fast roaming using PMK caching
- B. 802.11r roaming
- C. Proactive roaming
