9.3 wireless network design

You have been hired to design a wireless network for a SOHO environment. You are currently in the process of gathering network requirements from management. Which of the following questions should you ask? (Select three.)

Which type of data will be transmitted on the network? Is the size of the business expected to grow in the future? How many devices will need to be supported?

Which protocol is well known for its use in the home security and home automation industry, uses a mesh topology, makes devices act as repeaters, and has a low data transfer rate?

Z-Wave

You are designing a wireless network for a client. Your client needs the network to support a data rate of at least 150 Mbps. In addition, the client already has a wireless telephone system installed that operates at 2.4 GHz. Which 802.11 standard works best in this situation?

802.11n

Which of the following should you include in your site survey kit?

A tall ladder

Which of the following uses a 2.4 GHz ISM band, has fast transmission rates, and has been used for applications like geocaching and health monitors?

Ant+

Match each wireless term or concept on the left with its associated description on the right. Each term may be used more than once. (Not all descriptions have a matching term.)

Compares the Wi-Fi signal level 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

You are concerned that wireless access points might have been deployed within your organization without authorization. What should you do? (Select two. Each response is a complete solution.)

Conduct a site survey. Check the MAC addresses of devices that are connected to your wired switch.

Which of the following purposes do wireless site surveys fulfill? (Select two.)

Identify existing or potential sources of interference. Identify the coverage area and preferred placement of access points.

Which of the following does an SNR higher than 1:1 indicate?

More signal than noise

You have been hired to troubleshoot a wireless connectivity issue for two separate networks located within a close proximity. Both networks use a WAP from the same manufacturer, and all settings (with the exception of SSIDs) remain configured to their defaults. Which of the following might you suspect is the cause of the connectivity problems?

There are overlapping channels.
