NO.65 What term describes the effect of increasing the intensity of an RF wave with an antenna by focusing the energy in a specific direction?

NO.66 Which one of the following channels can be used for VHT transmissions?

NO.67 In a mesh BSS (MBSS), according to the 802.11-2016 standard, what device connect the mesh to an Ethernet network?

NO.68 A dual-band 802-1 lac AP must be powered by PoE. As a class 4 device, what power level should be received at the AP?

NO.69 What is always required to establish a high quality 2.4 GHz RF link at a distance of 3 miles (5 kilometers)?

NO.70 You are implementing a VHT-capable AP. Which one of the following channels is available in the
802.11-2016 standard, which was not available before the ratification of 802.11ac?

NO.71 The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The user indicate that they need more throughput and all stations are 5 GHz capable 802.11ac clients. The current AP configuration uses 20 MHz channels in both
2.4 GHz and 5 GHz. What is the least expensive solution available for increasing throughput for these users without implementing configuration options that are not recommended?

NO.72 Which data rate is supported by 802.11g radios that is not supported by 802.11a radios?

NO.73 What information is transmitted in the Beacon management frames of an HT access point to communicate about backward compatibility with ERP and HR/DSSS stations? (Choose 2)

NO.74 What is always required to establish a high quality 2.4 GHz RF link at a distance of 3 miles (5 kilometers)?

NO.75 You have been tasked with creating a wireless link between two buildings on a single campus. The link must support at least 150 Mbps data rates. What kind of WLAN technology role should you deploy?

NO.76 A string of characters and digits is entered into an AP and a client STA for WPA2 security. The string is 8 characters long. What is this string called?

NO.77 You are attempting to explain RF shadow and how it can cause lack of coverage. What common building item frequently causes RF shadow and must be accounted for in coverage plans?

NO.78 You are troubleshooting a controller-based AP that is unable to locate the controller. DHCP is not use and the controller is located at 10.10.10.81/24 while the AP is on the 10.10.16.0/24 network.
What should be inspected to verify proper configuration?

NO.79 You are deploying a WLAN with the access points configured for 10 mW of output power on the 2.4 GHz radios and 20 mW of output power on the 5GHz radios. Some semi-directional antennas are also in use. What kind of deployment is described?

NO.80 A natural disaster has occurred in a remote area that is approximately 40 miles from the response team headquarters. The response team must setup a local wireless network using 802.11 WLAN access points. What is the best method, of those listed, for implementation of network backhaul for communications across the Internet in this scenario?

NO.81 You are performing a post-implementation validation survey. What basic tool can be used to easily locate areas of high co-channel interference?

NO.82 You are deploying a WLAN with the access points configured for 10 mW of output power on the
2.4 GHz radios and 20 mW of output power on the 5 GHz radios. Some semi- directional antennas are also in use. What kind of deployment is described?

NO.83 You are deploying a WLAN with the access points configured for 10 mW of output power on the 2.4 GHz radios and 20 mW of output power on the 5GHz radios. Some semi-directional antennas are also in use. What kind of deployment is described?

NO.84 In addition to throughput enhancements, what other improvements does a dual-band 802.11ac AP provide when compared with 802.11a/g APs? (Choose 2)

NO.85 What is an advantage of using WPA2-Personal instead of WEP-128 as a security solution for
802.11 networks?

NO.86 Which IEEE 802.11 physical layer (PHY) specification includes support for and compatibility with both ERP and HR/DSSS?

NO.87 In addition to coverage analysis results, what should be included in a post-deployment site survey report to ensure WLAN users experience acceptable performance?
