QUESTION 17
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

The AP that covers the problem area requires a firmware update

The clients are improperly configured

The AP that covers the problem area has failed

The AP that covers the problem area is improperly configured

QUESTION 18
Which one of the following channels can be used for VHT transmissions?

QUESTION 19
You have been tasked with creating a wireless link between two buildings on a single campus. The link must support at least 150 Mbps data rates. What kind of WLAN technology role should you deploy?

QUESTION 20
You are troubleshooting a problem with interference from a non-802.11 device. Given that the device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum analyzer. You want to view the signal from the interfering device over time to see the activity that is generating.
What common spectrum analyzer view should you use for this analysis?

APs

Waterfall/Spectrogram

Real-time FFT

Clients

QUESTION 21
Which one of the following is not a factor considered when calculating the Link Budget for an outdoor point-to- point WLAN bridge link?

Operating frequency

MU-MIMO capabilities of the bridges

Receive antenna gain

Transmit power

QUESTION 22
What statement about 802.11 WLAN bridges is true?

WLAN bridges only work in the 2.4 GHz frequency band and they support only SISO communications

WLAN bridges must use a channel with acceptable SNR at both transceivers to maintain the desired data rate bi-directionally

WLAN bridges may support MIMO communication, but only if used in the GHz frequency band

WLAN bridges must be implemented such that no interference occurs on the channel anywhere between the two endpoints used to establish the bridge

QUESTION 23
You are implementing a VHT-capable AP. Which one of the following channels is available in the
802.11-2016 standard, which was not available before the ratification of 802.11ac?

153

161

144

QUESTION 24
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?

The laptop has a falling wireless adapter

The AP is overloaded during the work day

The external hard drive is USB 3.0 and is causing a significant increase in the noise floor when in use

The drivers in the laptop are corrupt

QUESTION 25
Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?

Dipole and yagi

Grid and sector

Patch and panel

Dish and grid

QUESTION 26
When replacing the antenna of a WLAN device with a similar antenna type that has a higher passive gain, what antenna characteristic will decrease?

Range

Beamwidth

Active gain

Receive sensitivity

QUESTION 27
What 802.11 network configuration would result in multiple stations broadcasting Beacon frames with the same BSSID but with different source addresses?

A single AP supports multiple BSSs with different SSIDs.

An IBSS is used instead of a BSS.

An SCA network is in use.

Laptop-based spectrum analyzer with a directional antenna

Laptop-based protocol analyzer with an omni-directional antenna

QUESTION 30
What fact is true regarding controllers and Aps in a split-MAC architecture?

Using centralized data forwarding, frames leaving the Aps are never tagged Ethernet frames with VLAN identifiers

An IP tunnel is established between the AP and controller for AP management and control functions

With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator

Management and data frames must be processed locally by the AP, while control frames are sent to the controller

QUESTION 31
You are troubleshooting a client issue on a Windows laptop. The laptop can see and connect to 2.4 GHz APs, but is does not even see 5 GHz APs. While evaluating the issue, you determine that this problem is happening for all of the laptops of this model in the organization. Several other tablets connect on channel 48 and channel 52 in the same work areas. What is the likely problem?

The clients are configured to use WPA and 5 GHz channels only support WPA2.

The client drivers are faulty and should be upgraded.

The antennas in the laptop have insufficient gain to detect the 5 GHz signals.

The access points are configured to disallow 5 GHz.

QUESTION 32
