In an enterprise WLAN, what condition will prevent a dual-band VHT/HT client device from performing a fast and seamless transition (i.e. latency-sensitive applications are not disrupted) between two access points that are managed by the same WLAN controller?
What is always required to establish a high quality 2.4 GHz RF link at a distance of 3 miles (5 kilometers)?
The IEEE 802.11a/n/ac physical layer technologies utilize the 5 GHz frequency band. What is true of the channels in this frequency spectrum?
The center frequency of channel 1 in the 2.4 GHz band is 2.412 GHz (2412 MHz).
What is the center frequency of channel 4?
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?
In an 802.11 2.4 GHz system, what 22 MHz channels are considered non-overlapping? (Choose 2)
In a long-distance RF link, what statement about Fade Margin is true?
As XYZ Company’s wireless specialist, you have been asked to troubleshoot some unexpected frame patterns in a wireless protocol capture. Your peers explain that the network’s beacon frames are inconsistent. That is, the BSSID is the same for all beacons, but the source address varies between three different addresses.
What network configuration would cause this beacon frame behavior?
As you prepare for a site survey in a multi-floor corporate office, you have learned about several wireless devices that support connection-oriented, real-time applications. These applications are sensitive to service interruptions and require excellent signal quality, low latency, and low loss. For that reason, it is important to identify sources of RF interference as well as building characteristics that would cause RF blockage or dead spots.
What systems or environmental characteristics are most likely to cause interference or RF blockage and disrupt service for these applications? (Choose 2)
How is throughput capacity scaled in a single channel architecture (SCA) WLAN system?
When using an RF splitter to connect one transceiver to sector antennas loss is incurred. What is this loss called?
You are using a tool that allows you to see signal strength for all APs in the area with a visual representation. It shows you SSIDs available and the security settings for each SSID. It allows you to filter by frequency band to see only 2.4 GHz networks or only 5 GHz networks. No additional features are available. What kind of application is described?
What word describes the bending of an RF signal as it passes through a medium of a varying density from that of free space?
You are onsite with a client to perform a post-deployment site survey. When verifying a multiple channel VoWiFi deployment using a VoWiFi handset, which aspect is most important?
Your consulting firm has recently been hired to complete a site survey for a company. Your engineers use predictive modeling software for surveying, but the company insists on a pre-deployment site visit.
What tasks should be performed as part of the pre-deployment visit to prepare for a predictive survey? (Choose 2)
In a Wi-Fi client configuration utility, what feature is most likely to be user configurable?
When planning an access point deployment that utilizes Power over Ethernet (PoE) switches at the network edge, what design decision could adversely affect the operation of 802.3-2012, Clause 33 APs?
What advantages does using predictive site survey modeling software offer over performing a manual site survey? (Choose 2)
