CWNP Certified Wireless Analysis Professional 認定 CWAP-405 試験問題 (Q113-Q118):

質問 # 113
Protocol analyzers may present field values in either binary, decimal or hexadecimal. What preceeds a hexadecimal value to indicate it is hexadecimal?

正解：C

解説：
A hexadecimal value is a value that uses base 16 notation, which means it can have digits from 0 to 9 and letters from A to F.
A hexadecimal value is usually preceded by 0x to indicate that it is hexadecimal and not decimal or binary.
For example, 0x0A is hexadecimal for 10 in decimal or 00001010 in binary. The other options are not valid prefixes for hexadecimal values.

質問 # 114
In which element of a Beacon frame would you look to identity the current HT protection mode in which an AP is operating?

正解：D

解説：
The HT protection mode in which an AP is operating can be identified by looking at the HT Operations element in a Beacon frame. The HT Operations element is a part of the Beacon frame that contains information about the High Throughput (HT) capabilities and operation of an 802.11n BSS. The HT Operations element has a field called HT Protection, which indicates how the BSS protects its HT transmissions from interference or collisions with non-HT devices or BSSs. The HT Protection field can have four values: No Protection, Nonmember Protection, 20 MHz Protection, or Non-HT Mixed Mode. The other options are not correct, as they do not contain information about the HT protection mode. The HT Protection element does not exist, the ERP Information element is used for Extended Rate PHY (ERP) protection mode for 802.11g devices, and the HT Capabilities element is used for indicating the supported HT features of an individual device.

質問 # 115
Which Spectrum Analyzer plot would show the percentage of time a signal is measured at a particular frequency?

正解：B

解説：
A Real-Time FFT plot shows the percentage of time a signal is present at specific frequencies.
This allows you to see how often energy appears at a given frequency, making it useful for identifying intermittent or periodic transmissions.


質問 # 116
Which statement is true regarding the Association Identifier (AID) used in IEEE 802.11 WLANs?

正解：C


質問 # 117
You're the WLAN administrator for a large retailer based at the HQ in New York. The London- based office has been complaining about WLAN disconnections around lunch time each day. You suspect this might be interference from the staff microwave, how might you test your theory from the New York office?

正解：A

解説：
Placing an AP into spectrum analyzer mode allows remote monitoring of RF energy in the 2.4 GHz band during the suspected time of interference. Microwave ovens emit broadband RF interference that is clearly visible in spectrum analysis. By observing the RF activity over lunch time, you can correlate interference patterns with the reported WLAN disconnections without needing to be physically present.
