QUESTION 28
You have received a report of poor wireless connections on the third floor of a building under your administration. Three individuals have reported the problem. Apparently, the connections are reporting a strong signal, but the users cannot access the Internet. With the problem identified, what is the next logical step in the troubleshooting process?

Perform corrective actions

Discover the scale of the problem

Create a plan of action or escalate the problem

Verify the solution

QUESTION 29
What advantages does using predictive site survey modeling software offer over performing a manual site survey? (Choose 2)

Predictive modeling software can predict the ideal access point location 100% of the time, whereas the results from manual surveyingare less reliable.

Predictive modeling software makes it simple to assess multiple different AP locations and then adjust and display the AP’s expected coverage pattern in almost real-time.

Predictive modeling software provides more reliable data than manual surveys when fine-tuning and validating access point placement after the installation.

The exact impact of interference sources from external networks can be more accurately measured when using predictive modeling software than with manual surveys.

It takes less time to create an initial site survey for a large facility when using predictive modeling software than when performing a manual survey.

QUESTION 30
What is always required to establish a high quality 2.4 GHz RF link at a distance of 3 miles (5 kilometers)?

Minimum output power level of 2 W

Accurate Earth Bulge calculations

Grid antennas at each endpoint

A minimum antenna gain of 11 dBi at both endpoints

A Fresnel Zone that is at least 60% clear of obstructions

QUESTION 31
Which unit of measurement, as formally defined, is an absolute unit that is used to quantify received signal power levels on a logarithmic scale?

SNI

VSWR

dBm

dBi

QUESTION 32
XYZ Company has decided to install an 802.11 WLAN system that will support 1083 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
