Question 611 - N10-008 discussion

Report
Export

A wireless network technician is receiving reports from some users who are unable to see both of the corporate SSIDs on their mobile devices. A site survey was recently commissioned, and the results verified acceptable RSSI from both APs in all user areas. The APs support modern wireless standards and are all broadcasting their SSIDs. The following table shows some of the current AP settings:

Which of the following changes would result in all of the user devices being capable of seeing both corporate SSIDs?

Configuring both APs to use the 802.11ac wireless standard
Answers
D.
Configuring both APs to use the 802.11ac wireless standard
Suggested answer: D

Explanation:

The change that would result in all of the user devices being capable of seeing both corporate SSIDs is configuring both APs to use the 802.11ac wireless standard. 802.11ac is a wireless standard that operates in the 5 GHz frequency band and offers high data rates and performance. However, not all wireless devices support 802.11ac, especially older ones that only operate in the 2.4 GHz frequency band. In the table, AP1 uses 802.11b, which is an outdated wireless standard that operates in the 2.4 GHz frequency band and offers low data rates and performance. AP2 uses 802.11a, which is an older wireless standard that operates in the 5 GHz frequency band and offers moderate data rates and performance. Therefore, some user devices may not be able to see both SSIDs because they are incompatible with either 802.11b or 802.11a. By configuring both APs to use 802.11ac, which is backward compatible with previous wireless standards, all user devices should be able to see both SSIDs.
