Question 14

One thousand concurrent users stream video to their laptops. A 30/70 split between 2.4 GHz and 5 GHz is used.

Based on client count, how many APs (rounded to the nearest whole number) are needed?

    Correct Answer: B

    To determine the number of APs needed based on client count, we first calculate the number of users on each frequency band. With a 30/70 split on 1000 users, 700 users connect to the 5 GHz band and 300 users to the 2.4 GHz band. Each AP can handle 25 concurrent users on the 5 GHz band. Dividing 700 users by 25 users per AP, we get 28 APs to manage the 5 GHz connections. Since 28 is the higher number needed to cover the user load, that is the number of APs required.

DRHoppoOption: B

agree with B: The math(s) are 70% of 1000 = 700/25 =28 , and 30% of 1000 = 300/25 = 12. use the greater number out the two calculations, therefore 28

This is not correct. Number of Access Points = Max (Number of Access Points based on throughput, Number of Access Points based on client count).

Knightime14Option: B

It's easier for me to remember that each AP can handle 25 concurrent 5GHz connections. I know it's essentially the same thing as the formula, it's just easier for me to remember.

txamiOption: B

Agree with all, this calculation appears in https://documentation.meraki.com/Architectures_and_Best_Practices/Cisco_Meraki_Best_Practice_Design/Best_Practice_Design_-_MR_Wireless/High_Density_Wi-Fi_Deployments

azjlmpangOption: B

#APs = (concurrent 5 GHz clients) / 25 = (70% x 1000) / 25 = 28

clrf26Option: B

#APs = (Concurrent 5GHz clients) /25 28 = (70% of 1000) / 25

What if the question stated 100 users instead of 1000. What would the answer be then?

Nathan_

That would be 3 as the formula is as followed #APs = (Concurrent 5GHz clients) /25 So that means (70% of 100) / 25 = 2.8 and you need to round up so that means 3

rocketplutoOption: B

Correct answer is B - they are asking for client count and not the number of APs based on application. If they noted based on application then it would be aggregate app throughput/device throughput=number of APs. Depending on assumptions that could be C.
