A. high-data bandwidth application
B. real-time application
C. console management interfaces
D. mobile apps
E. web-based application
正解：B

質問 2：
When performing an indoor predictive site survey to make the WLAN planning and design cycle more efficient, what is a best practice for configuration of the simulated APs in the predictive modeling software?
A. If dynamic RRM will be used, AP transmit power should be set to an estimated average level of the expected client devices, such as 25 mW.
B. All simulated APs should be set to 20 MHz channels only.
C. Always use the default 2.2 dBi omnidirectional antenna patterns for simulated APs.
D. Defining custom AP and antenna patterns will yield more accurate prediction data than the pre-configured vendor AP/antenna combinations.
正解：A

質問 3：
During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame showing an incorrect FCS. This frame is typical of those that were captured by the analyzer.
What does this frame reveal about the RF network in this area?
A. One station seems to be streaming video, thus may have reserved significant bandwidth via admission control
B. Contention Free is in place in this network, which may starve some non-QoS stations from access
C. The AP seems to be too far to provide enough coverage to this area
D. Multipath or excessive collisions seem to be an issue in this area
正解：D

質問 4：
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. mW mW
B. mW
C. 0 dBm = 1 mW
正解：C

質問 5：
What is a radome?
A. A type of semi-circular ceiling found in atriums and that is a heavy cause of RF reflection.
B. A piece of metal positioned behind APs mounted on outdoor poles, designed to limit the butterfly effect.
C. A weatherproof piece of plastic covering an antenna or antenna system.
D. The unit used to measure the signal reflected backward by the end of a cable.
正解：C

質問 6：
Excessive uplink RTP frame retransmissions can result in ____________.
A. Lowering of the data transmission rate by the transmitting station
B. Head-of-Line blocking at the receiver
C. MOS scores in excess of 5
D. Deauthentication of the transmitter by the receiver
正解：A

質問 7：
In this question, you will compare the mobility processes of a network that supports WPA2-Personal and WPA2-Enterprise. Assume the use of a 15-character ASCII passphrase for WPA2-Personal and EAP-TTLS/MSCHAPv2 with WPA2-Enterprise. Also, assume that proprietary roaming protocols are not supported.
When a device transitions from one BSS to another within the same ESS, what step must be performed in the WPA2-Enterprise transition that are not performed in the WPA2-Personal transition?
A. Open System Authentication
B. 802.11 Reassociation
C. 4-Way Handshake
D. 802.1X authentication
正解：D

質問 8：
What is the DSCP Per Hop Behavior equivalent classification of the 802.11 AC_VO priority level?
A. VO
B. AF31
C. EF
D. CS3
正解：C
