B. Latency is a measurement of the time delay experienced in the delivery of a frame.

C. Jitter is a measurement of the variance of the number of frames received from an application for a specific time interval.

D. Jitter is a measurement of average latency based on a sample of >100 frames.

E. Latency is a measurement of the time required to transmit two subsequent frames.

문제3

Using a SCA means that all APs will be using the same channel in a given layer. How is the AP with which the client associates determined?

A. All APs share a virtual BSSID. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

B. All APs share a virtual Multicast Address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

C. All APs share a virtual IP address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

D. The client selects the AP based on a known set of MAC to BSSID mappings stored in the clients authorized SSID listing.

정답: C

문제4

A business traveler from North America is in Europe. The hotel only provides coverage in 2.4 GHz. The traveler connects to the hotel's SSID and notices an AP in the hotel room.
However, the laptop reports a very low RSSI when connected. The traveler does not have the same problem when connecting in the lobby.
What would be the most likely cause of the low RSSI in the hotel room?
Response:

A. The AP in the room is transmitting on channel 13 and the traveler associated to a non-channel 13 AP located elsewhere.

B. The AP in the room is using Bluetooth instead of Wi-Fi.

C. The AP in the room is using ZigBee instead of Wi-Fi.

D. The switchport that the AP is connected to is only capable of transmitting at 10 Mbps.

정답: A

문제5

When using a predictive design tool, you have selected APs with an antenna gain 3 dBi and set the transmit power of the predicted APs to 25 mW.
What should be EIRP of the APs in the design?

A. 125 mW

B. 6.25 mW

C. 11 dBm

D. 17 dBm

정답: D

문제6

What best describes ensuring coverage requirements in a deployed WLAN?

A. Measuring the signal strength and number of APs at each location and comparing it to the requirement specifications

B. Verifying that a 3x3:3 gaming laptop can connect to the WLAN from all required locations

C. Verifying that the WLAN can be seen from all required locations

D. Verifying that you can connect to the WLAN from all required locations with the least capable device

정답: D

문제7

Your new customer is concerned about maintaining privacy for their proprietary information when you conduct information gathering for their WLAN design. Which document can you use to directly address their concern?

A. NDA

B. Hold Harmless

C. SoW

D. BoM

정답: A

문제8

What type of site survey helps determine if roaming is functioning as intended?

A. Predictive

B. Passive

C. Active

D. Spectrum analysis walkthrough

정답: C

문제9

You ate evaluating CO impact in 2 4 GHz. During the post-validation survey, you determine that 2 or 3 APs are seen from every location in the 2 4 GHz band with signal strengths above -75 dBm from all seen Aps. Does this show that CO has been removed from the environment given that three non-overlapping channels exist in 2.4 GHz and why?

A. Yes because you would see 3 APs m every location with a signal strength above -75 dBm if CO exists

B. No, because the goal is to see only 1 AP at each location in 2 4 GHz

C. Yes, because the goal is to see only l AP at each location in 2 4 GHz

D. No, because CCI can exist even with signals as low as -85 dBm to -93 dBm

정답: D

문제10

What is the DSCP Per Hop Behavior equivalent classification of the 802.11 AC_VO priority level?

A. CS3

B. AF31

C. VO

D. EF

정답: D

A. Office environments

B. Retail

C. Warehouses

D. Education

E. Healthcare

정답: B,D,E

문제12

What are the best practices for belter location accuracy when deploying Wi-Fi RTLS?

A. Place APs on the perimeter and throughout the required area and make sure that every client device is able to "hear" at least three APs

B. Place APs on the center of the required area and make sure that every client device is able to hear at least two APs

C. Place APs on the center of the required area and make sure that every client device is able to hear" at least three APs

D. Place APs on the perimeter of the required area and make sure that every client device is able to "hear" at least one AP

정답: A

문제13

After designing a WLAN infrastructure using predictive design software. What's the best way to validate the predictive design in the physical space before deployment, if time and budget allow for it?

A. Deploy all of the APs as they're shown in the predictive design and perform a passive site survey.

B. Deploy all of the APs as they're shown in the predictive design and perform an active site survey.

C. Perform an AP-on-a-Stick survey using AP locations based upon the predictive design to confirm each AP's placement.

D. Use a client device positioned where the APs will be installed and measure the signal from the client device.
