The IEEE 802.11-2016 standard requires VHT capable devices to be backward compatible with devices using which other 802.11 physical layer specification (PHY)?

A WLAN is implemented using wireless controllers. The APs must locate the controllers when powered on and connected to the network.

Which one of the following methods is commonly used to locate the controllers by the APs?

Which one of the following channels can be used for VHT transmissions?

The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The users indicate that they need more throughput and all stations are 5 GHz capable 802.11ac clients. The current AP configuration uses 20 MHz channels in both 2.4 GHz and 5 GHz.

What is the least expensive solution available for increasing throughput for these users without implementing configuration options that are not recommended?

What non-standard WLAN solution attempts to give a longer transmission windows to devices with higher data rates then devise with lower data rates?

You administer a small WLAN with nine access point. As a small business, you do not rum a RADIUS server and use WPA2-Personal for security. Recently, you changed the passphrase for WPA2-personal in all Aps and clients. Several users are now reporting the inability to connect to the network at time and it is constrained to one area of the building. When using scanner, you see that the AP covering that area is online

You are using a site survey tool for post-implementation validation. You have installed the appropriate adapter driver and imported a floor plan. Now, you want to take the next step in proper tool use.

What must you do before gathering survey data after the floor plan is imported?

You are attempting to explain RF shadow and how it can cause lack of coverage.

What common building item frequently causes RF shadow and must be accounted for in coverage plans?

When using a spectrum analyzer to look for non-Wi-Fi interference sources, you notice significant interference across the entire 2.4 GHz band (not on a few select frequencies) within the desktop area of a user's workspace, but the interference disappears quickly after just 2 meters.

What is the most likely cause of this interference?

A standard PoE injector is used to power an access point requiring 802.3at. CAT6 cabling is in use.

What is the maximum distance supported between the access point and the Ethernet switch with the use of a midspan power injector?

What standard is referenced in the 802.11-2016 specification and is recommended for robust WLAN client security?

What statement about the beamwidth of an RF antenna is true?

When replacing the antenna of a WLAN device with a similar antenna type that has a higher passive gain, what antenna characteristic will decrease?

You are evaluating access points for use in the 5GHz frequency band.

What PHY supports this band and supports 80 MHz channels?

You are managing a wireless access point in autonomous mode using the Web based interface. You capture traffic during this management task and notice that you can see the HTML code of the Web pages for access point management.

What error in administration could be the cause of the security concern?

What ID is typically mapped to an AP's MAC address if a single BSS is implemented?

The center frequency of channel 1 in the 2.4 GHz band is 2.412 GHz (2412 MHz).

What is the center frequency of channel 4?

In a mesh BSS (MBSS), according to the 802.11-2016 standard, what device connect the mesh to an Ethernet network?

You are planning for PoE in a standard office deployment.

Which one of these devices is least likely to be a PoE PD?

A client complains of low data rates on his computer. When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11acAP. Both the client and AP are 2x2:2 devices.

What is the likely cause of the low data rate issue?

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?

In a mesh BSS (MBSS), according to the 802.11-2016 standard, what device connects the mesh to an Ethernet network?

Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter.

What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?
