Question1: What may occur when an RF wave encounters an object large in relation to the wavelength during propagation?

Question2: What is the maximum data rate of the original 802.11 standard DSSS PHY (Physical Layer)?

Question3: Which one of these vertical market facilities is most likely to require a high density deployment?

Question4: What process is used in 802.11 networks to provide confidentiality?

Question5: Why would you need to know about neighbor 802.11 networks to create an effective WLAN implementation plan for a site?

Question6: What is the name given to the WPA2 implementation that uses a PSK (Pre-Shared Key)?

Question7: Which one of the following is considered a data-intensive application?

Question8: Using Dynamic Rate Switching (DRS), when a client must change to a lower data rate, what best defines the action?

Question9: What term is used to define the variance in delay or latency between packets on a network?

Question10: When planning for a bridge link between locations, in addition to the link distance, what requirement should be known in order to determine the antennas, settings and bridges to use?

Question11: What kind of antenna is most frequently used with indoor APs?

Question12: Which one of the following is an example of an antenna used mostly for bridge links?

Question13: In a highly-reflective environment, what result can have a negative impact on SISO 802.11 devices?

Question14: What is defined as the strength of an RF wave?

Question15: In addition to coverage requirements, what primary requirements must be defined to ensure a WLAN performs as required?

Question16: In what frequency band does an 802.11g (ERP) device operate?

Question17: When an AP supports both 2.4 GHz and 5 GHz, what term is commonly used to define this AP?

Question18: You are recommending a solution for a hospital environment. What room is most likely to require an AP inside the room to ensure coverage in that area because the walls block RF signals?

Question19: An AP has two Ethernet wired networking ports. One (port 1) is labeled with a Power over Ethernet (PoE) indicator and the other (port 2) is not. What is unique about port 1 when compared to port 2?

Question20: What statement best defines a staggered channel plan or multiple channel architecture (MCA)?

Question21: What must be defined in order to properly determine capacity requirements?

Question22: What should be used to manage an AP that requires direct web-based configuration?

Question23: What 802.11 fast roaming solution allows a client to authenticate to a different AP than that to which it is connected through the AP to which it is connected?

Question24: An AP offers a captive portal within the AP software. For what is this feature most likely to be used?

Question25: What channel width rarely, if ever, should be used in the 2.4 GHz frequency band, even though it is supported by the standard and available devices?

Question26: Why is it considered a mistake to use 160 MHz channels in most 5 GHz frequency band enterprise deployments?

Question27: What 802.11 PHY (Physical Layer) operates in 60 GHz?

Question28: What is required for some 5 GHz channels that may prevent their consistent use near an airport?

Question29: Why must a cloud-managed AP have access to the Internet for initial setup?

Question30: What user behavior is most likely to require Wi-Fi coverage between buildings on the same campus?
