- Q1Which statement about the 802.11a standard is true?The 802.11a standard uses the 2.4GHz spectrum.The 802.11a standard can use both the 2.4GHz and 5GHz spectrum.The 802.11a standard uses the 5GHz spectrum.The 802.11a standard uses the 400MHz spectrum.30s
- Q2In which standard was Multiple Input and Multiple Output (MIMO) introduced?802.11ac802.11n802.11g802.11b30s
- Q3What is the maximum data rate of 802.11n?300 Mbps600 Mbps288 Mbps54 Mbps30s
- Q4Which describes the spectrum in 802.11ac?The 802.11ac standard utilizes the 2.4GHz spectrum, as it is more resilient and capable of longer distances.The 802.11ac standard utilizes both the 2.4Ghz spectrum and 5GHz spectrum actively.The 802.11ac standard utilizes the 5GHz spectrum. It is also capable of utilizing the 2.4GHz spectrum, but then it is no longer the 802.11ac standard.The 802.11ac standard utilizes the 7GHz spectrum, since 2.4GHz and 5GHz were becoming too congested.30s
- Q5Which statement describes TDMA?TDMA uses code multiplexing techniques to separate the utilization of throughput given to separate subscribers.TDMA utilizes throughput on a single frequency and separates it into time slots to allocate throughput for subscribers. Each subscriber is given a separate time slot to send and receive data.TDMA uses time slots to allocate throughput for subscribers, putting each time slot on a different frequency to ensure they are secure.TDMA utilizes separate frequencies for each subscriber so that each subscriber has a dedicated frequency and throughput.30s
- Q6Which of the following is a hardware requirement in phones that utilize Global System for Mobile Communication (GSM)?GPSSIMLTEPIN30s
- Q7What does CDMA stand for?Creative Division Multiple AccessCollaborative Division Multiple AccessCaptive Division Multiple AccessCode Division Multiple Access30s
- Q8If there are no restrictions, how many channels are available in the 2.4GHz spectrum?1214131130s
- Q9Which of the following is a reason to use the 2.4GHz wireless spectrum over the 5.0GHz wireless spectrum?The 2.4GHz spectrum offers more available channels to utilize over the 5GHz spectrum.The 2.4GHz spectrum offers the capability of higher throughput over the 5GHz spectrum.The 2.4GHz spectrum provides a stronger, more resilient signal better suited for longer distances or obstructions.The 2.4GHz spectrum ensures less chance of interference from other devices in the spectrum.30s
- Q10Which of the following terms defines the wireless practice of adding additional antennas to an AP to provide additional spatial streams?IBSSMIMOCSMA/CDChannel bonding30s
- Q11What is a Yagi antenna?An omnidirectional antenna with a bar and fins.A unidirectional antenna shaped like a dish or grid.An omnidirectional antenna shaped like a dish or grid.A unidirectional antenna with a bar and fins.30s
- Q12What type of antenna sends the signal in all directions?Log periodicUnidirectionalOmnidirectionalParabolic30s
- Q13Which tool would be very valuable to assist with performing a site survey for a wireless implementation?Packet sniffersWEP cracking toolHeat mapCable crimpers30s
