Exam N10-008 topic 1 question 50 discussion

This question is not worded well. First off: Wireless Client Isolation is a security feature that prevents wireless clients from communicating with one another. This feature is useful for guest and BYOD SSIDs adding a level of security to limit attacks and threats between devices connected to the wireless networks. This question I think assumes the guest network is coming from one building and not the other. For this I would Vote A (but it's a crummy question)

Correct answer is A. Enabling wireless client isolation(Answer C) cannot be correct. wireless client isolation means users using wireless connection cannot have access to the internal network resources only. Even if wireless client isolation is enables, they can download inappropriate content from the internet.

It is A, you have to check the wording "adjacent building"

I think the key words in the question are "adjacent building", so A-reducing the power is the correct answer. I guess users in the main building can continue to download inappropriate content, if they wish. Sucks to be a heathen in the adjacent building. Seriously, though, the question is not well-phrased.

Reducing the power levels of the wireless network will decrease the range of the wireless signal, which can prevent users in the adjacent building from connecting to the network.

The power level should be reduced for the radio transmitter in the wireless access points. With a reduced power level, the signal will not travel as far. You can ensure the signal remains within the building's interior only by conducting a site survey and adjusting your power levels of each wireless access point. The other options, if changed, would affect the availability of the network. Adjustments for new wireless signal strength requires you to consider the following: * Client = Received Signal Strength Indication (RSSI) (decibel) * Access Point = Effective Equivalent Isotropic Radiate Power (EIRP) Decibels over Isotropic (dBi) Wireless channel frequencies must meet the Federal Communication Commission (FCC) rules & therefore can still easily be accessed. Enabling wireless client isolation only protects the Internal network (Intranet). Port security would allow you to block external & internal network accesses, but would affect every client on the network lest you were to use a whitelisting protocol authentication service like RADIUS, this change would take time to implement however.

To most easily mitigate the issue of users in an adjacent building connecting to the company's guest wireless network to download inappropriate material, the network administrator should consider option C: Enable wireless client isolation.

Guys the easiest solution is reduce the power.

the question say ( the MOST easily mitigate this issue).. so the answer must be A , other wise C will be correct here.

Reducing the wireless power levels could be a possible solution to limit the coverage area of the guest wireless network, but it might not be the easiest solution. A determined user could still find a way to connect to the network, and legitimate guests may also have a harder time connecting. Enabling wireless client isolation would be the easiest solution to mitigate this issue as it would prevent clients on the same wireless network from communicating with each other, effectively blocking any unwanted file sharing or downloads. Therefore, the correct answer should be C.

reduce the power and problem sorted

I agree with the A for reducing the SSID broadcasting scenario. If this was my network, I would have a syslog server, text monitoring, & deploy an internet shutoff trigger if a user was looking at inappropriate material. Not on my network.

Both A and C are correct, but question is which is the "Easiest" solution.

Answer is A

Should'nt be C ?

Reduce the wireless power level
