問題1

At a university, the WLAN has been successfully deployed for ubiquitous access for faculty, students, and guests. Many student computer labs are available throughout the campus with wired network connectivity, but there are also a few smaller lab areas and workstations where Ethernet cabling is not available. For student wireless use, the students must authenticate against RADIUS/Active Directory using PEAP. Also, the network administrators at this university would like administrative access to these workstations when they are not in use by students so that the administrators can manage group policies, update OS patches, and perform other routine software maintenance.
What deployment option is available and recommended for both student use and remote administration of these workstations?

A. Roaming user profiles should be used so that the users do not loser the family pictures on their desktops.

B. The WLAN infrastructure vendor is responsible for providing proprietary client connectivity options to facilitate device connectivity without user interaction.

C. Due to the architecture of 802.1X port-based access control, it is not possible for a wireless-only computer to access network services required by network administrators in this scenario.

D. These workstations should be Ethernet-connected to a wireless client bridge, which will maintain network connectivity independent of student connectivity status.

正確答案: D

問題2

When one AP among several in an ESS is elected to manage the others, what deployment model is in use?

A. Autonomous

B. Virtual controller-based

C. Cloud-based

D. Controller-based

正確答案: D

問題3

You are working with APs that support external antennas. One particular cell is experiencing link problems. It appears that several client devices have very low output power settings and a link mismatch is occurring with the AP.
Which one of the following actions would best resolve the problem?

A. Install higher gain antennas in the APs.

B. Increase the output power of the radio in all APs.

C. Decrease the output power of the client devices.

D. Install APs with only internal antennas.

正確答案: B

問題4

What might a PoE injector be used for during a site survey?

A. to test throughput

B. to act as a WLAN client

C. to power APs

D. to adjust signal strength

正確答案: C

問題5

Given: As the wireless network administrator for XYZ Company, you are planning to upgrade your aging wireless network infrastructure, as well as some clients, to support 802.11ac. In your research, you have discovered that your new wireless client devices and infrastructure are 802.11ac, WMM, and WMM-PS certified by the Wi-Fi Alliance. Some of your existing client devices are 802.11a/b/g devices that do not support WMM.
Given this information, what scenario is possible when your company's employees begin using both types of client devices on the new WLAN?

A. WMM-PS enabled APs will allow both WMM-PS and non-WMM-PS stations to use the trigger-and-delivery mechanism, but WMM-PS stations will get priority.

B. Performance and battery life will be inconsistent between WMM-PS and non-WMM-PS client devices when used with applications that support WMM-PS.

C. All WMM-PS certified client devices will be prevented from utilizing WMM-PS features until all stations in use on the wireless medium are WMM-PS certified.

D. The WLAN infrastructure will set the dozing times of the WMM-PS certified client devices based upon their WMM access category, while the non-WMM-PS client devices will continue to use PS-Poll frames.

正確答案: B

問題6

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. 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.

B. 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.

C. 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.

D. 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.

正確答案: D

問題7

Which one of the following is a valid argument against using 80 MHz 8902.11ac channels?

A. 80 MHz channels are not supported in any enterprise APs.

B. When 80 MHz channels are used; 40 MHz adapters or clients cannot connect.

C. The total number of unique channel configurations for each AP is lessened.

D. 80 MHz channels reduce the data rate, and therefore throughput, of the BSS significantly.
