- C.
All stations can hear traffic in the same segment / coverage boundary
- D.
Only station with correct address uses data. All others will ignore data.
Correct Answer(s)
A. Only one radio can transmit at a time
C. All stations can hear traffic in the same segment / coverage boundary
D. Only station with correct address uses data. All others will ignore data.Explanation
The CSMA/CA protocol used in Wireless LAN has the following characteristics: Only one radio can transmit at a time, all stations can hear traffic in the same segment/coverage boundary, and only the station with the correct address uses data while others ignore it. This protocol helps improve performance by terminating transmission as soon as a collision is detected, reducing the time required before a retry can be attempted.Rate this question:

Higher the Signal equals higher data rate. And higher the data rate equal higher capacity
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that a higher signal strength generally results in a higher data rate. This is because a stronger signal allows for more efficient transmission of data, reducing the chances of errors or data loss. Additionally, a higher data rate means that more data can be transmitted in a given amount of time, thereby increasing the capacity of the system to handle larger amounts of data.Rate this question:

Which if the following is not a feature of 11ac specs ?
- A.
Up to 8 spatial streams supported
- B.
256 QAM
- C.
80/160 Mhz channels
- D.
Dual band support
Correct Answer
D. Dual band supportExplanation
The given correct answer for this question is "dual band support." The 11ac specs do not include support for dual band. Dual band support refers to the ability of a device to operate on both the 2.4 GHz and 5 GHz frequency bands. However, 11ac only operates on the 5 GHz frequency band, providing faster speeds and better performance compared to previous standards.Rate this question:

Is it possible to deploy SPoT with just 1 AP ?
- A.
Yes. If accuracy is not important and only "Presence" is desired.
- B.
Yes. 1 AP can provides acuracy of between 5-8m. This level of accuracy is more than adequate for most deployments
- C.
No. Only 3 or more APs are required
- D.
Yes. 1 AP can provides acuracy of 8-15m. This level of accuracy is more than adequate for most deployments
Correct Answer
A. Yes. If accuracy is not important and only "Presence" is desired.Explanation
Yes, it is possible to deploy SPoT with just 1 AP if accuracy is not important and only "Presence" is desired. This means that the system will be able to detect the presence of a device in a general area but may not provide precise location information. In cases where a rough estimate of location is sufficient, deploying SPoT with just 1 AP can be a viable option.Rate this question:

Generally more APs are required to achieved better accuracy. For 5m accuracy, you will require at mean RSSI of at least ___ dBm or better with 3 or more APs.
- A.
-65 dBm
- B.
- 67 dBm
- C.
-75 dBm
- D.
-70 dBm
Correct Answer
D. -70 dBmExplanation
Generally, more access points (APs) are required to achieve better accuracy in wireless communication. In this case, for a 5m accuracy, you will need a mean Received Signal Strength Indicator (RSSI) of at least -70 dBm or better with 3 or more APs. RSSI is a measure of the power level of the received signal, and a lower value indicates a stronger signal. Therefore, a mean RSSI of -70 dBm or better ensures a stronger and more accurate signal for the desired accuracy level.Rate this question:

A reseller asked for guidance on deploying a high density Wi-Fi network. What is the common best practices that you can suggest to him ? (Choose 2)
- A.
Look for ways to shrink the cell size and place the APs close to the users if possible.
- B.
Utilize both bands to maximise the AP radio resources
- C.
Need large number of APs to get the needed capacity
- D.
Statically mapped each AP with the right channel to ensure the full spectrum is being used.
Correct Answer(s)
A. Look for ways to shrink the cell size and place the APs close to the users if possible.
C. Need large number of APs to get the needed capacityExplanation
The first best practice is to look for ways to shrink the cell size and place the access points (APs) close to the users if possible. This is important because it helps to improve signal strength and reduce interference, resulting in better performance for users. The second best practice is to deploy a large number of APs to meet the required capacity. This ensures that there are enough APs available to handle the high density of users and provide a reliable and fast Wi-Fi network experience.Rate this question:
