質問 3：
You have been asked to determine the path loss to a particular client device and have been given the loss table below and the map exhibit at the bottom. Assume that the client device is located at the location identified by the red square in the bottom left hand section of the map exhibit and that this location is 44ft (37db free space loss) from AP207 and 68ft (55db free space loss) from AP 224. Which of the following represents the path loss at 5Ghz from the AP207 and AP224 to the client device?
A. 40db and 70db
B. 20db and 100db
C. 10db and 70db
D. 30db and 90db
正解：A
質問 4：
During the execution of the site survey, your assistant informs you that the data rate is decreasing as he moves away from the AP. How can this behavior be best explained?
A. It is not normal and must be a function of multipath.
B. It is normal and usually caused by other stations transmitting.
C. It is not normal and indicates a hardware problem.
D. It is a normal function of Dynamic Rate Shifting.
正解：D
質問 5：
After performing an initial site survey for a daily newspaper's editorial department, you determine that the only way to provide enough throughput in the main cubicle office area is by co-locating access points. The design will require numerous APs to be installed very near to each other. Which of the following WLAN standards would allow the greatest number of non-overlapping co-located APs in this situation?
A. 802.11g
B. 802.11
C. 802.11b
D. 802.11a
正解：D
質問 6：
You are working with a WLAN customer that has chosen to have a single flat network. When designing this network, which of the following can hinder network performance the MOST?
A. Having one Broadcast Domain
B. Setting the D71M to 10
C. Having too many VLANs
D. Putting the Access Points on different VLANS
正解：A
質問 7：
Which of the following design considerations is true of EVVB100 Voice Communicators but not of EVVP Series VoWLAN Smartphones?
A. Web access VLANs can use either band.
B. Bar code scans can be sent on 2.4 GHz band.
C. Bluetooth can be used only on 2.4 GHz band.
D. Voice ESSIDs can only be on 2.4 GHz band.
正解：D
質問 8：
You are designing a WLAN for a new customer and have been given a Customer Checklist for WLAN.
Given this checklist, please answer the test item(s) below.
Based on the data provided in the Customer Checklist for WLAN, select the most cost effective equipment for this deployment?
A. RFS4000and AP6511s
B. RFS4000 and AP7131S
C. AP7131NS
D. RFS4000 and AP650s
正解：D
質問 9：
You are using LANPlanner to design an 802.11b/g/n WLAN which is to be used by portable laptop PCs and 802.11b-only RTLS tags. In the LANPlanner predictive site survey shown in Exhibit A.4.1.04 at the bottom, an arrow points to a region that has been identified as having the weakest RSSI coverage (Cyan color) measuring -82 dBm. Using the raw values contained in Chart A in the exhibit at the bottom, and ignoring any additional fade margins or fudge factors, what is the maximum MCS level that can be supported using 20 MHz-wide 2.4 GHz channels?
A. MCS2
B. MCS5
C. MCS3
D. MCS7
E. MCS4
F. MCS6
G. MCS1
