What type of antenna is used in cellular base towers to concentrate radio transmission coverage into specific geometric sectors (e.g., 120-degree slices)?
Directional/sector antennas focus electromagnetic energy into specific pie-shaped geographic sectors to reduce interference and increase frequency reuse.
Which optical transmission window is most commonly used in long-haul fiber optics due to achieving the lowest attenuation (~0.2 dB/km)?
The third optical telecommunications window around 1550 nm wavelength exhibits minimal fiber attenuation (about 0.2 dB/km), ideal for long-distance DWDM networks.
Which statements about the devices in a classic Bluetooth piconet are correct?
In classic Bluetooth, a piconet has one master and up to seven active slave devices simultaneously. Therefore A and B are correct.
What is the primary vulnerability exploited in an ARP Cache Poisoning (ARP Spoofing) attack?
ARP is stateless and lacks authentication. Devices will cache incoming ARP replies even if they never requested them, allowing attackers to forge IP-to-MAC associations.
