b) Router
c) Switch
d) Repeater
Answer: b) Router
Explanation: A router broadcasts the Wi-Fi signal and manages connections between devices and the internet.
9. Question: What encryption method is used in WPA3?
Options:
a) TKIP
b) Simultaneous Authentication of Equals (SAE)
c) RC4
d) WEP Key
Answer: b) Simultaneous Authentication of Equals (SAE)
Explanation: WPA3 uses SAE for enhanced security, making it more resistant to brute-force attacks.
10. Question: How does MIMO improve Wi-Fi performance?
Options:
a) By increasing signal range
