Q30. A company has hired you to perform a pre-deployment site survey of their facility. During an interview, the network manager informs you that the new wireless network must use 5 GHz bands and OFDM, and VoWiFi handsets will be used extensively over the wireless network.
What items do you need to include in the RF site survey report? (Choose 2)

Q31. What advantages does using predictive site survey modeling software offer over performing a manual site survey? (Choose 2)

Q32. Which unit of measurement, as formally defined, is an absolute unit that is used to quantify received signal power levels on a logarithmic scale?

Q33. Your manager asked you to locate a solution that allows for centralized monitoring of WLAN performance over time. He wants a single pane of glass for administration and monitoring of the solution. What do you recommend?

Q34. What is appended to the end of each 802.11 data frame after the payload?

Q35. What 802.11 PHY uses available space in very low frequency ranges that is not in use at the time by broadcast video signals?

Q36. In an 802.11 2.4 GHz system, what 22 MHz channels are considered non-overlapping?

Q37. A client STA must choose the best AP for connectivity. As part of the evaluation, it must verify compatible data rates. What can the client STA use to verify that an AP supports the same data rates that it supports?

Q38. To ease user complexity, your company has implemented a single SSID for all employees. However, the network administrator needs a way to control the network resources that can be accessed by each employee based in their department.
What WLAN feature would allow the network administrator to accomplish this task?

Q39. ABC Company is planning to install a new 802.11ac WLAN, but wants to upgrade its wired infrastructure first to provide the best user experience possible. ABC Company has hired you to perform the RF site survey.
During the interview with the network manager, you are told that the new Ethernet edge switches will support VoIP phones and 802.11 access points, both using 802.3 PoE.
After hearing this information, what immediate concerns do you note?

Q40. What statement about 802.3. Clause 33 Power over Ethernet is true?

Q41. An 802.11-based network uses an AP and has several connecting clients. The clients include iPhones, iPads, laptops and one desktop. What WLAN use case is represented?

Q42. A non-802.11 device is suspected of causing interference on the WLAN. You are not certain of the location or type of device. What is the best solution for locating this non-802.11 device?

Q43. What factors does not influence the distance at which an RF signal can be effectively received?

Q44. What term describes the effect of increasing the intensity of an RF wave with an antenna by focusing the energy in a specific direction?

Q45. You are troubleshooting a controller-based AP that is unable to locate the controller. DHCP is not use and the controller is located at 10.10.10.81/24 while the AP is on the 10.10.16.0/24 network.
What should be inspected to verify proper configuration?

Q46. You are troubleshooting a client problem with a 2.4 GHz WLAN connection. The client is experiencing surprisingly low data rates during the work day. You analyze the workspace outside of business hours and detect a strong signal with a typical noise floor at the client location. During working hours, the user works with a laptop in the area and uses an external USB hard drive for continuous data access. The user also states that the laptop works as expected on her home network. The user working approximately 8 feet away from this client experiences no problems.
Based on this information, what is the likely cause of the problem?

Q47. ABC Company is planning a point-to-multipoint outdoor bridge deployment with standalone (autonomous) 802.11 bridge units. 802.1X/EAP will be used for bridge authentication. A Linux- based RADIUS server will be used for authentication. What device in the bridge Implementation as the 802.1X Authenticator?

Q48. In addition to coverage analysis results, what should be included in a post-deployment site survey report to ensure WLAN users experience acceptable performance?
