NEW QUESTION 3
An engineer is performing a predictive wireless design for a carpeted office space, which requires voice capability and location services. Which two requirements are inputs to the design? (Choose two.)

• A. overlapping -67 dBm coverage from three access points
• B. overlapping -75 dBm coverage from three access points
• C. overlapping-72 dBm coverage from two access points
• D. continuous -67 dBm coverage from one access point
• E. continuous -72 dBm coverage from one access point

Answer: AD

Explanation: For a voice network the APs are grouped closer together and have more overlap than a data-only installation because voice clients need to roam to a better AP before dropping packets. Generally, you should create smaller cells than for data-only networks and ensure the overlapping cell edges are at or above -67 dBm.

NEW QUESTION 10
An initial meeting has been scheduled for a proposed site survey of a customer headquarters location. Which two types of information would be valuable to collect prior to the formal kickoff meeting?

• A. Number of branch locations
• B. Plans for branch expansion
• C. Number of customers
• D. Business type
• E. Site type (urban, suburban, external environmental sensitivity, etc.)

Answer: AB

NEW QUESTION 11
What is a common cause for signal attenuation?

• A. Cinder block wall
• B. Office window
• C. Metal door
• D. Glass wall

Answer: C

NEW QUESTION 12
An engineer is planning for a 24 Mbps data rate for a new installation. What is the coverage area from the AP if the environment and other factors are not taken into consideration?

• A. 225 feet
• B. 80 feet
• C. 150 feet
• D. 100 feet

Answer: A

Explanation: Coverage (Cell Size)
Lower data rates can be demodulated across greater distances than higher data rates. This is because of the lower complexity encoding schemes — the signal can be understood at a lower SNR. Enable lower data rates in order to increase the effective range of the AP; disable the lower data rates in order to decrease the effective range of the AP.

NEW QUESTION 13
Which three options are benefits of U-APSD? (Choose three.)

• A. optimized power-save mode periods
• B. increased call capacity
• C. bandwidth reservation
• D. synchronization of the transmission and reception of voice frames
• E. efficient roaming
• F. priority bandwidth and polling

Answer: ABD

Explanation: Unscheduled automatic power-save delivery (U-APSD) is a feature that has two key benefits:
The primary benefit of U-APSD is that it allows the voice client to synchronize the transmission and reception of voice frames with the AP, thereby allowing the client to go into power-save mode between the
transmission/reception of each voice frame tuple. The WLAN client frame transmission in the access
categories supporting U-APSD triggers the AP to send any data frames queued for that WLAN client in that AC. A U-APSD client remains listening to the AP until it receives a frame from the AP with an end-of-service period (EOSP) bit set. This tells the client that it can now go back into its power-save mode. This triggering mechanism is considered a more efficient use of client power than the regular listening for beacons method, at a period controlled by the delivery traffic indication map (DTIM) interval, because the latency and jitter requirements of voice are such that a WVoIP client would either not be in power-save mode during a call, resulting in reduced talk times, or would use a short DTIM interval, resulting in reduced standby times. The
use of U-APSD allows the use of long DTIM intervals to maximize standby time without sacrificing call quality. The U-APSD feature can be applied individually across access categories, allowing U-APSD can be applied to the voice ACs in the AP, but the other ACs still use the standard power save feature.
The secondary benefit of this feature is increased call capacity. The coupling of transmission buffered data frames from the AP with the triggering data frame from the WLAN client allows the frames from the AP to be sent without the accompanying interframe spacing and random backoff, thereby reducing the contention experience by call.

NEW QUESTION 14

• A. the number of clients that will roam through the facility
