click on 801.11 and select b/g click on SSID and select BYOD (since the ipad is personal and BYOD means bring your own device) click on frequency and select 2.4Ghz (it has longer range that can penetrate in which 5Ghz is poor at.) At Wireless Security Mode, Click on Security Mode,Select the WPA2 and the password should be set to TotallySecure! (WPA2 or Enterprise mode, more suited to organizational or business use. while WPA-PSK relies on a shared passcode for access and is usually used in home environments.)

Why would you select WPA2? It states in the example that the BYOD network is using WPA-PSK and the question is just about connecting the users device.

I would say select AC for the 802.11 then select WPA-PSK because its already configuredd that way in the 2nd to the last snapshpt shown. Yes I strongly recommend 2.4GHz as well because that has a longer reach

I think the reasoning for 5GHz is because 802.11ac runs at 5GHz.

802.11ac only operates on 5 GHz, 802.11ax and 802.11n operate in both

No, 802.11ac only works on the 5Ghz band

It is backward compatible to b/g/n which support 2.4GHz

I took this exam and about 60% of the questions on the exam were on here. Almost all of the performance-based questions were on this as well. There was 1 PBQ that was not and it was using windows CMD commands to view the hostname, IP, domain, and group policy of 3 workstations.

While I can't see the WiFi heat map, I'm going to assume based on the distance from the WAP that the 5 GHz would be slightly out of range. 802.11 -> b/g (the only 2.4 GHz options listed) SSID -> BYOD Frequency -> 2.4 GHz Security Mode -> WPA

Also, note that it says "without adjusting her home WiFi configuration" You are NOT supposed to change anything, the BYOD network is on WPA so you select WPA.

The question mentions a personal device to be operated in a corporation so we need to pick "BYOD", the reason for 2.4 GHz is that the heating map which not provided in the question should show 2.4 GHz covering room 3, unlike the 5 GHz spectrum (according to the heating map which is missed) then follow security procedures according to configuration page (BYOD ..........)

I had this simulation where I had to set up SOHO with two columns, UPS and Surge Protector. But I couldn't figure out what they were asking to properly solve this SIM. Did anyone encounter this SIM?

Why isn't WPA2 the answer? It is more secure than WPA. And when it states b/g, is this referring to 802.b and 802.g ? In other words 2.4GHz. Why would that be correct?

It's not asking you to make a secure WiFi configuration, you are just connecting the device. The BYOD network uses WPA so you connect using WPA. 2.4 GHz is correct likely because the 5 GHz would not reach the location the device is in.

The exam does have the heat map functioning. Unless they change it the Wi-Fi should be b/g with 2.4 GHz.

i'm leaning towards b/g but still a bit confused with the way the standards work. My understanding of 802.11ac is that due to its backwards compatibility and use of dualband that it should be the choice in most cases (basing this on most articles i've read about it that are dated later than 2013).

802.11ac runs at 5GHz. The ac supports beamforming which helps overcome the fact that range is shorter than 2.4. But the heat map is the key to the whole PBQ.

Why 5ghz over 2.4?

could be wrong or maybe it has something to do with the heat map if that's actually viewable in the real exam

I believe it should be 2.4 because of the distance of the iPad to the AP.
