When replacing the antenna of a WLAN device with a similar antenna type that has a higher passive gain, what antenna characteristic will decrease?
You are attempting to locate the cause of a performance problem in two WLAN cells in a mostly overlapping coverage area. You note that one AP is on channel 1 and the other is on channel 2. When you document your findings, what term do you use to describe the problem in this configuration?
You are evaluating access points for use in the 5 GHZ frequency band. What PHY supports this band and supports 80 MHz channels?
You are evaluating a connection that states the data rate is 150 Mbps. What is the expected throughput of this connection?
You are troubleshooting a controller-based AP that is unable to locate the controller. DHCP is not used 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?
What is always required to establish a high quality 2.4 GHz RF link at a distance of 3 miles (5 kilometers)?
What statement about 802.11 WLAN bridges is true?
When implementing PoE, what role is played by a switch?
As an RF wave propagates through space, the wave front experiences natural expansion that reduces its signal strength in an area. What term describes the rate at which this expansion happens?
You are troubleshooting an issue reported by several wireless users. The problem is contained to one cell (several users connected to the same AP). You manage the WLAN and no other network devices. After analysis it appears to be a switch problem. What action should be taken?
What non-standard WLAN solution attempts to give a longer transmission windows to devices with higher data rates than devices with lower data rates?
Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter.
What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?
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?
An IEEE 802.11 amendment is in the daft state. What impact does this draft amendment have on the 802.11 standard?
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?
What statement about 802.11 WLAN bridges is true?
What standard is referenced in the 802.11-2016 specification and is recommended for robust WLAN client security?
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?
An RF sigma sometimes bends as it passes through some material other than free space. What is the term that describes this behavior?
You are performing a post-implementation validation survey. What basic tool can be used to easily locate areas of high co-channel interference?
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?
You are tasked with performing a throughput test on the WLAN. The manager asks that you use open source tools to reduce costs. What open source tool is designed to perform a throughput test?
You are evaluating a connection that states the data rate is 150 Mbps. What is the expected throughput of this connection?
