What is the most suitable antenna option to be used when designing a WLAN infrastructure with APs mounted on a ceiling with a height of more than 20 feet and having all of the client stations used from the floor?A . PatchB . DishC . GridD . Low-gain dipoleView AnswerAnswer:...
What metric implements the simplest algorithm and lowest accuracy in networks requiring locations?
What metric implements the simplest algorithm and lowest accuracy in networks requiring locations?A . Angle of Arrival (AoA)B . Time of Arrival (ToA)C . Time Difference of Arrival (TDoA)D . Received Signal Strength Indicator (RSSI)View AnswerAnswer: A Explanation: Reference: https://www.ijert.org/research/different-approaches-of-angle-of-arrival-techniques-in-wirelesssensor-networks-IJERTV2IS2346.pdf
What is the most likely reason for this result?
You performed a site survey with two USB Wi-Fi adapters using a special driver written for the site survey software. After deployment, you realized that the client devices used by your customer are getting lower RSSI values than that shown during your site survey. What is the most likely reason...
What issues could be caused by the use of USB 3.0 that will impact your site survey?
When surveying an existing WLAN infrastructure for a possible redesign, you use two Wi-Fi USB adapters to collect RSSI data and two USB spectrum analysis adapters to collect RF spectrum data. Since your laptop doesn’t have enough USB ports, you use a 4-port powered USB 3.0 hub. What issues could...
What’s the best way to validate the predictive design in the physical space before deployment, if time and budget allow for it?
After designing a WLAN infrastructure using predictive design software. What’s the best way to validate the predictive design in the physical space before deployment, if time and budget allow for it?A . Deploy all of the APs as they’re shown in the predictive design and perform an active site survey.B...
What is the most likely cause of this problem?
Your customer’s 802.11n laptops are not able to see the SSID in the 5 GHz band in the conference room. When doing a walkthrough using one of these laptops, you confirm that it is unable to see the SSID in the 5 GHz band in the conference room. When using...
What feature might be enabled on the WLAN infrastructure that is preventing you from communicating with other devices on that subnet?
You and 10 other people are connected to a public hotspot. You issue a ping sweep on the network, but you can’t find any devices on the same subnet as yours. What feature might be enabled on the WLAN infrastructure that is preventing you from communicating with other devices on...
When designing a static channel plan for an office using voice devices near an airport, which range of channels should be avoided to ensure optimal performance when implemented?
When designing a static channel plan for an office using voice devices near an airport, which range of channels should be avoided to ensure optimal performance when implemented?A . 36-40B . 44-48C . 116-124D . 1-11View AnswerAnswer: C
Why is this not sound advice?
During an RFP analysis, one of the vendors mentioned that you’ll need to upgrade your Gigabit Ethernet switches to MultiGig switches to ensure support for 802.11ac and 802.11ax, which both offer data rates over 1Gbps. Why is this not sound advice?A . Because neither of the technologies support data rates...
To support MultiGig, what is the best choice of cabling?
Switches and APs have already been chosen by your customer. All switches support 802.3bz MultiGig interfaces and APs are 4x4:4 802.11ac wave 2 capable of using dual-5GHz and have one MultiGig interface. Some cable drops for the APs will run for more than 180.5 feet (or 55 meters). To support...
