D. 30db and 90db
正解：A

質問 2：
You are a Wireless Design Expert for your Manufacturing Company and require a new wireless network to be deployed in your facility. The site is approximately 100,000 sq. ft. (30,000 sq. meters). The Access Points need to provide 802.11n connectivity at speeds up to 100mbps using 2X3:2 MIMO at a minimum. There is also a requirement for the Access Points to bridge data traffic for short periods of time (<30 minutes) locally but be managed via a centralized controller which resides in a NOC in another site. The WAN connection between the sites is low bandwidth and is known to lose connectivity for short periods of time. Which AP model would meet the given requirements in a cost effective solution?
A. AP650
B. AP6532
C. AP7131
D. AP7181
正解：B

質問 3：
You are designing a new 802.11 installation that will be built on an IEEE 802.3 10/100/1000 BaseT-backbone infrastructure. All IEEE 802.11n access points and VoIP phones will be IEEE 802.3 Power over Ethernet (PoE) powered devices. The 802.11n access points will utilize dual band 3X3 MIMO and require 802.3at PoE. Which is a true statement regarding a WLAN deployment of this nature?
A. Only IEEE 802.3af PoE devices can operate on a Gigabit network infrastructure.
B. VoIP phones and access points cannot be located on the same access layer PoE switches.
C. An accurate power sourcing equipment (PSE) power budget must be performed.
D. This installation can only use endpoint Power Sourcing Equipment (PSE) devices.
正解：C

質問 4：
Quality of Service (QoS) features available on Motorola Wi-NG 5.x controllers and access points can give preferred access to the voice users of a WLAN. If this feature is not properly configured it is possible to squeeze out normal data users. Which of the following are Wi-NG 5.x methods that allow the administrator to adjust the WLAN capacity for QoS and non-QoS capacity (select TWO)?
A. Transmission Opportunity (TXOP)
B. Unscheduled Automatic Power Saved Delivery (UAPSD)
C. Traffic Specification (TSPEC)
D. Voice Call Admission Control (VCAC)
正解：C,D

質問 5：
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.

Assume this implementation now requires support for SMART RF. This being the case, what is the MOST likely effect this would have on the design?
A. You may need more APs to provide the overlap of coverage needed to support SMART RF functionality
B. You will need less APs as SMART RF will compensate for the coverage holes
C. You wouldn't need to modify the design to support SMART RF
D. You will need to add another switch to support SMART RF
正解：A

質問 6：
You are designing a system for an indoor customer site that will have 6 Independent APs (IAPs). In order to minimize co-channel interference on the 802.11b/g/n band, how should the IAPs be configured?
A. The IAPs should use channels 1, 6 and 11 and should be placed such that no two neighbor IAPs are on the same channel
B. Co-channel interference only occurs on the 802.11a/n wireless band and is not a factor for 802.11b/g/n
C. All the IAPs should be on the same channel
D. The IAPs should be replaced with standard Access Ports
正解：A

質問 7：
After preparing a LAN Planner predictive site survey to visualize data rate coverage for an upgrade to an existing 802.11b/g WLAN, you are informed that the customer will also need to continue to provide support for 802.11b bar code scanners throughout the facility. Using LANPlanner, you predict that with the current placement of APs, a maximum 802.llg data rate of 18 Mbps will be available in the locations indicated by arrows on the heatmap shown in Exhibit A.4.2.01 at the bottom. This is due to dense wall construction materials and low AP output power settings. Using the raw values shown in Chart A in the exhibit, and ignoring any additional fade margins or fudge factors, what would be the maximum, possible 802.11b connection rate at the indicated locations?

A. 11Mbps
B. 2 Mbps
C. 6 Mbps
D. 5.5 Mbps
E. 1 Mbps
正解：B

質問 8：
You are a network design engineer and are assigned to provide an enterprise S02.1X/EAP solution to secure your company's IEEE 802.11n WLAN. What networking protocol/service that provides centralized Authentication, Authorization, and Accounting (AAA) management for computers to connect and use wireless network resources can be implemented?
A. Remote Authentication DialinUser Service (RADIUS)
B. Virtual Private Networking (VPN)
C. Secure Shell (SSH)
D. Public Key Infrastructure (PKI)
E. Wi-Fi Protected Access (WPA) Passphrase
正解：A

質問 9：
The IEEE 802.lln amendment to the standard addresses several PHY layer enhancements. One of these enhancements is "Channel Bonding" allowing for 40 MHz wide channels. Without taking any specific local regulatory domain into consideration, what is the maximum number of non-overlapping 40 MHz wide channels that can exist in the 2.4 GHz ISM band?
A. 1
B. 3
C. 20
D. 11
E. 6
F. 2
正解：A
