質問 1：
When implementing a WLAN in a hospital environment, which one of the following is a common mistake made by designers?
A. Considering client devices over the laptops and tablets.
B. Feeling that health privacy regulations have an impact on WLAN security requirements.
C. Failing to consider multi-floor propagation.
D. Thinking that lead walls impact RF behavior.
正解：C
質問 2：
What commonly causes a client-to-AP link imbalance?
A. The AP's antenna gain is lower than the client's antenna gain
B. The AP's transmit power is significantly lower than the client's transmit power
C. The client's transmit power is significantly lower than the AP's transmit power
D. The client's antenna gain is lower than the AP's antenna gain
正解：C
質問 3：
What basic RF math formula should be used as a baseline to convert an RF value in units of dBm into a value of mW?
*Note: "dBm" in the formulas represents the known dBm value
A. 0 dBm = 1 mW
B. mW mW
C. mW
正解：A
質問 4：
As part of the design for a large WLAN that will include hundreds of APs operating in both 2.4 GHz and 5 GHz bands, you are changing AP settings so that APs on the same channel are spaced significantly far apart such that they have lessened impact on each other's BSAs. What common WLAN program are you attempting to diminish?
A. Bluetooth interface
B. CCI
C. Incorrect security settings
D. ACI
正解：B
質問 5：
Given: The 802.11ac APs you have selected for your public access deployment support many of the PHY and MAC enhancements offered by the 802.11n and 802.11ac amendments. The AP is configured for a single-band (2.4 GHz) and only allows 20 MHz channels. The WLAN radio in the AP is a 3x3 802.11n chip that supports two spatial streams.
What is the maximum MCS rate that could be supported by this AP?
A. 54 Mbps
B. 65 Mbps
C. 144 Mbps
D. 108 Mbps
正解：C
質問 6：
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. Each SSID is mapped to a static VLAN assignment
B. Radio signal metrics (RSSI, SNR, etc.) of WLAN clients are triangulated for location-based VLAN assignment during association
C. Upstream AAA servers dynamically assign VLANs to each user or group profile
D. Multiple VLAN pools are designated for an SSID and user IP addresses are selected in a round-robin fashion from the associated pools
