Questions # 61:

Which antenna type is best for covering a long corridor in a building?

Options:

Omni-directional antenna

Patch antenna

Yagi antenna

Dipole antenna

Answer

Questions # 62:

A wireless engineer must optimize RF performance for multiple buildings with multiple types of construction and user density. Which two actions must be taken? (Choose two.)

Options:

Configure Flexconnect groups for each building.

Configure WMM profiles for each building.

Configure AP groups for each area type.

Configure RF profiles for each area type.

Enable DTPC on the network.

Answer

C, D

Explanation

To optimize RF performance across different buildings and user densities: C. Configure AP groups for each area type - This allows for customized settings for APs serving different areas. D. Configure RF profiles for each area type - RF profiles enable the customization of RF parameters to suit the specific needs of each building or area type.

Questions # 63:

In a stadium deployment, which WLAN design approach is most recommended?

Options:

Few APs with maximum power on 2.4 GHz

High-density design with sectorized directional antennas

Ceiling-mounted omni antennas across the stadium bowl

Deploying APs only on one side of the stadium

Answer

Questions # 64:

An engineer changed the TPC Power Threshold for a wireless deployment from the default value to -65 dBm. The engineer conducts a new post-deployment Survey to validate the results. What is the expected outcome?

Options:

Increase cell size

Decreased client signal strength

Increased received sensitivity

Decreased channel overlap

Answer

Explanation

Changing the TPC Power Threshold to -65 dBm would generally result in a decrease in the transmit power of APs to maintain a smaller cell size. This helps in reducing interference and improving overall network performance. A lower threshold means the APs reduce their power to ensure the signal does not exceed -65 dBm, leading to decreased signal strength at the client side.

Questions # 65:

An engineer is designing a wireless network that will support many different types of wireless clients. When conducting the survey, which client must be used to ensure a consistent experience for all of the wireless clients?

Options:

the client that has the highest RF properties

the client that is used most by the company

the client that is used least by the company

the client with the worst RF characteristics

Answer

Explanation

When designing a wireless network for diverse clients, it’s crucial to ensure that the network will be reliable for all users. Therefore, surveys should be conducted with the client that has the worst RF characteristics, as indicated in option D. This approach ensures that the network is designed to support even the weakest client, thereby providing a consistent experience for all users.

Questions # 66:

A wireless engineer must assess constraints for a future WLAN deployment for a site that consists of o®ce cubicles. Which signal propagation attenuation result is associated with this environment?

Options:

re ection

absorption

noise

refraction

Answer

Explanation

In an office environment with cubicles, signal propagation is most commonly affected by absorption. This is because the materials used in cubicle walls, such as fabric and other dense substances, tend to absorb the radio frequency (RF) signals used in WLANs, leading to attenuation.

Questions # 67:

An engineer is designing a wireless network to support hyperlocation in an environment that already has APs installed. During the survey, the engineer notices that the APs are pointing in different directions. What is the recommended way to align the APs to easily determine AP

Azimuth, X-Y, and ceiling height information, and minimize confusion and user-entered errors?

Options:

APs must be aligned pointing toward the nearest wall.

APs must be aligned pointing toward each other.

APs must be aligned in the same direction.

APs can be aligned all four ways.

Answer

Explanation

For supporting hyperlocation, it is recommended that APs be aligned in the same direction. This uniform alignment helps in accurately determining the AP Azimuth, X-Y, and ceiling height information, which is crucial for hyperlocation accuracy and minimizes confusion and user-entered errors.

Questions # 68:

A stadium deployment requires handling a very high number of clients per AP. Which design principle should be applied?
