質問 2：
While configuring your site survey software for an upcoming manual survey project, you notice the configuration option for "Network Card Simu-lation". What is the purpose of such a feature and when would you use it?
A. The site survey software manufacturer allows you to view the collected RF data as if it were collected by a different type of adapter. This functionality allows you to review survey data to determine how the RF environment will likely look based on the receive sensitivity and other RF capabilities of a specific client adapter.
B. This setting allows the site survey software to convert the AP's measured downlink RF data into a simulated data set as if the same data were transmitted by a specific client station. It is useful for determining uplink client performance when clients are located far from APs as well as projecting cell size for ad hoc networks.
C. Since WLAN adapters are not typically calibrated by manufacturers, this setting is a form of software calibration in which you can calibrate an (uncalibrated) adapter to match one of the calibrated adapters shown in the list. This process improves the reliability of RF data collection and reporting when uncalibrated adapters are used.
D. This is the configuration area in which you specify the adapter type that will be used for the site survey so that the survey software can interpret that adapter's reported metrics (based on proprietary formulas) into an RF measurement that is standardized by the survey software and known to its users. This is done for every survey.
正解：A

質問 3：
In a large enterprise (5000+ wireless users), by what would NOT be a recommended method by which IP addresses and VLANs are assigned to different clients associated to the same AP?
A. Multiple VLAN pools are designated for an SSID and user IP addresses are selected in a round-robin fashion from the associated pools
B. Upstream AAA servers dynamically assign VLANs to each user or group profile
C. Radio signal metrics (RSSI, SNR, etc.) of WLAN clients are triangulated for location-based VLAN assignment during association
D. Each SSID is mapped to a static VLAN assignment
正解：C

A. Autonomous
B. Cloud-based
C. SCA
D. MCA
正解：C
