question
You are building a wireless network within and between two buildings. The buildings are separated by more then 3000 feet. The wireless network should meet the following requirements....
answer
Building 1-location A Right-facing directional Antenna/WPA2 with CCMP Building 1-location B Omni directional Antenna/WPA2 with CCMP Building 1-location C Left-facing directional Antenna/WPA2 with CCMP Building 1-location D Right-Facing Parabolic Antenna/WPA2 with CCMP Building 2-location A Omni Directional/WEP with Open authentication Building 2-location B Left-facing Parabolic Antenna/WPA2 with CCMP
Explanation: You are building a wireless network within and between two buildings. The buildings are separated by more then 3000 feet. The wireless network should meet the following requirements.The network should have a single SSID that is broadcasted from both locationsThe network should have the same password at both locationsUsers should be able to seamlessly connect to the network as they move between buildingsTo meet these requirements, you will need to use a wireless access point (WAP) at each location. The WAPs will need to be configured with the same SSID and password. You will also need to configure the WAPs to use the same wireless channel. This will allow users to connect to the network as they move between buildings.
question
Your wireless network consist of multiple wireless 802.11n access points that are configured as follows.....This network is required to support an ever-increasing number of devices. what should you do?
answer
Double the bandwidth assigned per channel to 40MHz
question
What purpose does a wireless site survey serve? select two
answer
To Identify existing or potential sources of interference To identify the coverage area and preferred placement of access points.
Explanation: A wireless site survey can serve two purposes: 1. To assess the feasibility of using wireless technology in a particular location 2. To determine the optimal placement of wireless access points and other wireless infrastructure
question
You are designing a wireless network for a client. Your client needs the network to support data rate of at least 150Mbps. In addition, the client already has a wireless telephone system installed that operates 2.4GHz. Which 802.11 standard will work best in this situation?
answer
802.11n
question
You are designing a wireless network for a client. Your client needs the network to support a data rate of at least 54Mbps. Which 802.11 standard will work best in this situation? select two
answer
802.11n 802.11a
question
You are designing an update to your clients wireless network. The existing wireless network uses 802.11g equipment, which your client complains runs to slowly. She wants to upgrade the network to run 150Mbps or faster. Which 802.11 standard will work best in this situation.
answer
802.11n
question
You have been hired to design a wireless network for a SOHO environment. Which of the following questions should you ask? select three
answer
How many devices will need to be supported Is the business expected to grow in size in the future What type of data will be transmitted on the network
question
To optimize your network, you want to configure your wireless AP to use a channel that meets the following criteria. non-overlapping, low utilization, low interference.
answer
channel 1
Explanation: When configuring a wireless AP, you want to use a channel that is non-overlapping with other channels in use, has low utilization, and is low in interference. Non-overlapping channels will provide the best possible signal for your devices, while low utilization and low interference will help to keep your connection speeds high.
question
Match each wireless term or concept on the left with its associated description on the right
answer
Compares the level of the WIFI signal to the level of background radio signals/ Signal to Noise ratio Checks channel utilization and identifies sources of RF inference/ Spectrum analysis Identifies how strong a radio signal is at the receiver/Received Signal Level Identifies the number of useful bits delivered from the senders to the receiver/ Causes multiple copies of the same radio signal to be received by the receiving antenna/ Bounce Degrades wireless network performance/ Device saturation
Explanation: 1. 802.112. Ad hoc3. Infrastructure4. Wireless access point1. 802.11 is a set of standards for wireless LAN communication.2. Ad hoc is a type of wireless network where nodes communicate directly with each other without the use of an access point.3. Infrastructure is a type of wireless network where nodes communicate with each other through an access point.4. A wireless access point is a device that allows wireless devices to connect to a wired network.
