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 > Prefix matching > Suffix matching > Keyword matching
- D. Exact matching > Keyword matching > Suffix matching > Prefix matching
正解：A
解説：
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.

質問 # 22
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%.
正解：C、D
解説：
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.
