A high-density wireless network is designed.
Which Cisco WLC configuration setting must be incorporated in the design to encourage clients to use the 5 GHz spectrum?
Answer:
Question 17Selectable Answer
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.)
A customer is concerned about mesh backhaul link security.
Which level of encryption does the backhaul link use?
Answer:
Question 19Selectable Answer
Which statement about AP failover priority for access points when configured with priority 1 or 4 is true?
Answer:
Question 20Selectable Answer
An enterprise is using a Cisco AireOS controller and Wi-Fi 6 APs. The controller is installed in the head office, and the employees primarily use Apple OS devices. The APs broadcast WLAN ENT-WLAN406558520-1 for the employees and a guest WLAN with similar naming.
What needs to be enabled on the controller to optimize roaming?
Answer:
Question 21Selectable Answer
Campus users report a poor wireless experience. An engineer investigating the issue notices that in high-density areas, the wireless clients fail to switch the AP to which are automatically connected. This sticky client behavior is causing roaming issues.
Which feature must the engineer configure?
Answer:
Question 22Selectable Answer
What is the attenuation value of a human body on a wireless signal?
Answer: Explanation:
Signal Attenuation Signal attenuation or signal loss occurs even as the signal passes through air. The loss of signal strength is more pronounced as the signal passes through different objects. A transmit power of 20 mW is equivalent to 13 dBm. Therefore, if the transmitted power at the entry point of a plasterboard wall is at 13 dBm, the signal strength is reduced to 10 dBm when exiting that wall. This table shows the likely loss in signal
strength caused by various types of objects.

Each site surveyed has different levels of multipath distortion, signal loses, and signal noise. Hospitals are typically the most challenging environment to survey due to high multipath distortion, signal losses and signal noise. Hospitals take longer to survey, require a denser population of access points, and require higher performance standards. Manufacturing and shop floors are the next hardest to survey. These sites generally have metal siding and many metal objects on the floor, which result in reflected signals that recreate multipath distortion. Office buildings and hospitality sites generally have high signal attenuation but a lesser degree of multipath distortion.
