The 802.11 protocol specifies a fundamental channel access method that is required for all stations and is used in all IBSS and BSS networks.
What is this fundamental channel access method called?
What WLAN system feature is required to produce a scenario with the following configuration on a single access point? (Choose 2)
1. SSID = Guest / BSSID = AA:AA:AA:AA:AA:AA /
VLAN = 22 / Subnet = 192.168.22.0 / RF Channel = 6
2. SSID = Corporate / BSSID = BB:BB:BB:BB:BB:BB /
VLAN = 33 / Subnet = 192.168.33.0 / RF Channel = 6 / User Type A
3. SSID = Corporate / BSSID = BB:BB:BB:BB:BB:BB /
VLAN = 44 / Subnet = 192.168.44.0 / RF Channel = 6 / User Type B
What is an advantage of using WPA2-Personal instead of WEP-128 as a security solution for 802.11 networks?
In addition to throughput enhancements, what other improvements does a dual-band 802.11ac AP provide when compared with 802.11a/g APs? (Choose 2)
As defined in the 802.11 specification, legacy Power Save requires an inefficient back-and-forth frame exchange process. Due to this inefficiency, many WLAN device implementations use a variation of 802.11 Power Save to accomplish the same function.
What non-standard power save behavior is used by most Wi-Fi devices in actual legacy Power Save implementations?
What item is essential for performing a manual RF site survey for a warehouse facility?
You are onsite with a client to perform a post-deployment site survey. When verifying a multiple channel VoWiFi deployment using a VoWiFi handset, which aspect is most important?
As a consultant, you have been hired by ABC Company to implement an outdoor WLAN connection between two buildings that are 2 kilometers (1.24 miles) from each other, with no obstructions in between.
Your first required objective is to create a point-to-point link between the two buildings within the local regulatory body’s 800 mW EIRP maximum.
Your second required objective is to provide an industry-standard security solution capable of supporting mutual authentication.
As an optional objective, you must minimize the amount of interference from, and to, nearby WLAN networks.
You install an OFDM wireless bridge at each building, configuring one in root mode and the other in non-root mode. You set each radio for 100 mW (20 dBm) and attach 9 dBi omni-directional antennas to both. You configure the network for WPA2-Enterprise with PEAPv0/EAP-MSCHAPv2 authentication.
Which statement is true about the solution you chose to deploy?
XYZ Company has hired you to perform an indoor site survey of their 5-story facility. They own the building and rents out unused floors (floors 2 and 4) to other companies, and the other companies already use 802.11 WLANs. XYZ Company wants all of the offices they occupy to be surveyed as part of the project.
What actions should be recommended as part of the site survey project? (Choose 2)
What are two channel modes specified by the 802.11n (High Throughput) PHY? (Choose 2)
What term describes the effect of increasing the intensity of an RF wave with an antenna by focusing the energy in a specific direction?
When planning an access point deployment that utilizes Power over Ethernet (PoE) switches at the network edge, what design decision could adversely affect the operation of 802.3-2012, Clause 33 APs?
What statements about the SSID are true? (Choose 2)
