Question 1 of 30

Which two statements about distributed automatic radio resource provisioning (DARRP) are correct? (Choose two.)

A.

DARRP performs continuous spectrum analysis to detect sources of interference. It uses this information to allow the AP to select the optimum channel.

B.

DARRP performs measurements of the number of BSSIDs and their signal strength (RSSI). The controller then uses this information to select the optimum channel for the AP.

C.

DARRP measurements can be scheduled to occur at specific times.

D.

DARRP requires that wireless intrusion detection (WIDS) be enabled to detect neighboring devices.

Correct Answer: BC

DARRP (Distributed Automatic Radio Resource Provisioning) technology enables APs to optimize their channels and power levels based on environmental factors. It performs measurements of the number of BSSIDs and their signal strength (RSSI) to determine the optimal channel. Additionally, DARRP measurements can be scheduled to occur at specific times, allowing administrators to control when the optimization process takes place. This scheduling capability helps in managing network resources efficiently. Therefore, the correct statements are that DARRP performs measurements of RSSI and BSSIDs, and that these measurements can be scheduled.

Question 2 of 30

Which factor is the best indicator of wireless client connection quality?

A.

Downstream link rate, the connection rate for the AP to the client

B.

The receive signal strength (RSS) of the client at the AP

C.

Upstream link rate, the connection rate for the client to the AP

D.

The channel utilization of the channel the client is using

Correct Answer: B

The receive signal strength (RSS) of the client at the AP is the best indicator of wireless client connection quality. RSS measures how well the client's device is able to hear the signal from the access point, which directly affects the overall quality of the wireless connection. Higher RSS values generally indicate a stronger and more reliable connection.

Question 3 of 30

When configuring Auto TX Power control on an AP radio, which two statements best describe how the radio responds? (Choose two.)

A.

When the AP detects any other wireless signal stronger that -70 dBm, it will reduce its transmission power until it reaches the minimum configured TX power limit.

B.

When the AP detects PF Interference from an unknown source such as a cordless phone with a signal stronger that -70 dBm, it will increase its transmission power until it reaches the maximum configured TX power limit.

C.

When the AP detects any wireless client signal weaker than -70 dBm, it will reduce its transmission power until it reaches the maximum configured TX power limit.

D.

When the AP detects any interference from a trusted neighboring AP stronger that -70 dBm, it will reduce its transmission power until it reaches the minimum configured TX power limit.

Correct Answer: AD

Automatic Transmission Power control in AP radios primarily adjusts the power based on the environment to minimize interference and optimize coverage. When the AP detects any other wireless signal stronger than a certain threshold, like -70 dBm, it typically reduces its transmission power to minimize interference, which aligns with statement A. Similarly, if interference is detected from a trusted neighboring AP with a strong signal, the AP will also reduce its transmission power to prevent overlap and interference, as mentioned in statement D. Therefore, the correct statements are A and D.

Question 4 of 30

Refer to the exhibits.

Exhibit A.

Exhibit B.

Exhibit C.

A wireless network has been installed in a small office building and is being used by a business to connect its wireless clients. The network is used for multiple purposes, including corporate access, guest access, and connecting point-of-sale and Io׀¢ devices.

Users connecting to the guest network located in the reception area are reporting slow performance. The network administrator is reviewing the information shown in the exhibits as part of the ongoing investigation of the problem. They show the profile used for the AP and the controller RF analysis output together with a screenshot of the GUI showing a summary of the AP and its neighboring APs.

To improve performance for the users connecting to the guest network in this area, which configuration change is most likely to improve performance?

A.

Increase the transmission power of the AP radios

B.

Enable frequency handoff on the AP to band steer clients

C.

Reduce the number of wireless networks being broadcast by the AP

D.

Install another AP in the reception area to improve available bandwidth

Correct Answer: D

The key issue identified is slow performance for the guest network. To address this, the most effective approach would be to improve available bandwidth in the reception area, which is best accomplished by installing another AP. Increasing the transmission power might exacerbate interference, and enabling frequency handoff won't help since the clients are already on the 5 GHz band. Reducing the number of wireless networks being broadcast by the AP would likely have minimal impact.

Question 5 of 30

Which two statements about background rogue scanning are correct? (Choose two.)

A.

A dedicated radio configured for background scanning can support the connection of wireless clients

B.

When detecting rogue APs, a dedicated radio configured for background scanning can suppress the rogue AP

C.

Background rogue scanning requires DARRP to be enabled on the AP instance

D.

A dedicated radio configured for background scanning can detect rogue devices on all other channels in its configured frequency band.

Correct Answer: AD

A dedicated radio configured for background scanning can support the connection of wireless clients as it scans periodically while also functioning as a regular access point when needed, providing service to clients. Additionally, a dedicated radio set for background scanning can detect rogue devices on all other channels in its configured frequency band, as it scans all channels within the frequency band periodically to identify potential rogue devices.
