You are troubleshooting a client issue on a Windows laptop. The laptop can see and connect to
2.4 GHz APs, but it does not even see 5 GHz APs. While evaluating the issue, you determine that this problem is happening for all of the laptops of this model in the organization. Several other tablets connect on channel 48 and channel 52 in the same work areas. What is the likely problem?

• A.The antennas in the laptops have insufficient gain to detect the 5 GHz signals
• B.The client drivers are faulty and should be upgraded
• C.The access points are configured to disallow 5 GHz
• D.The clients are configured to use WPA and 5 GHz channels only support WPA2

In addition to coverage analysis results, what should be included in a post-deployment site survey report to ensure WLAN users experience acceptable performance?

• A.Application Layer protocol availability analysis results
• B.WAN interface analysts results
• C.Layer 4 protocol availability analysis results
• D.Capacity analysis results

XYZ Company has decided to install an 802.11 WLAN system that will support 1000 wireless users, but they are concerned about network security. XYZ is interested in deploying standardized security features. In addition to WPA2-Enterprise with PEAP and role-based access control, XYZ would like to support management frame protection as well as a fast secure roaming protocol for future mobile handsets.
As XYZ Company selects a product to deploy, what two IEEE amendments, which are included in
802.11- 2016, should be supported to provide the management frame protection and fast secure roaming security features?

• A.802.11z and 802.11w
• B.802.11r and 802.11w
• C.802.11r and 802.11k
• D.802.11j and 802.11k

A client complains of low data rates on his computer. When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11acAP. Both the client and AP are 2x2:2 devices.
What is the likely cause of the low data rate issue?

• A.Weak signal strength
• B.Too few spatial streams
• C.Lack of support for 802.11n
• D.CAT5e cabling run to the AP
