A hospital's wireless network is used for both life-critical monitoring devices and general internet access. The network administrator must ensure that the monitoring devices have priority over other traffic. The current network uses a single SSID for all devices. Which approach would best ensure the monitoring devices receive priority?

Creating a separate SSID for monitoring devices and using QoS policies

Using the same SSID but enabling WMM

Increasing the transmit power of the APs

Using a different frequency band for monitoring devices

A company deploys a new wireless network in a large open-plan office. After installation, users on the far side of the office report weak signals and dropped connections. The network administrator checks the access point placement and finds that the APs are mounted on metal support beams. Which RF propagation issue is most likely causing the problem?

Signal absorption by the metal beams

Signal reflection off the metal beams creating nulls and dead zones

Interference from the office's fluorescent lighting

Excessive transmit power causing clients to be unable to hear the AP

A warehouse uses handheld scanners that connect to a wireless network. The scanners are moved throughout the facility, and the network administrator notices that some scanners lose connectivity when they are behind large metal shelving units. Which wireless principle best explains this behavior?

RF signals are absorbed by metal, so the signal strength drops significantly behind the shelving.

RF signals are reflected by metal surfaces, creating areas where the signal is weak or null due to multipath cancellation.

The scanners are experiencing interference from other wireless devices in the warehouse, not from the shelving.

The scanners are operating on a frequency that cannot penetrate metal, so the signal is blocked entirely.

A retail store's wireless network is used for point-of-sale (POS) terminals and customer Wi-Fi. The store manager notices that during peak hours, the POS terminals experience frequent disconnections and slow transactions. A wireless audit reveals that a nearby competitor has installed a new Wi-Fi network using the same channel as the store's POS network. Which type of wireless threat is most directly affecting the POS terminals?

Rogue access point on the same channel

Jamming attack using a high-power transmitter

Denial of service via co-channel interference

Eavesdropping on POS transactions

A network engineer is planning a wireless network for a multi-story office building. The engineer wants to minimize interference between floors. Which RF propagation concept should the engineer consider when placing access points on different floors?

Multipath reflection off the ceiling

Signal attenuation through floor materials

Diffraction around the building edges
