What is a recommended practice to prevent unauthorized access to a wireless network?

Allow open access and rely on MAC filtering

Use WPA2 or WPA3 with a strong passphrase

Disable all encryption for better performance

A security analyst is investigating a series of Bluetooth attacks in a corporate environment. The analyst finds that an attacker was able to pair with a victim's phone and read contacts and messages without the victim's knowledge. The phone was in discoverable mode. Which attack occurred, and what is the most effective countermeasure?

Bluejacking; set the phone to non-discoverable mode

Packet sniffing; use WPA2 encryption

Bluesnarfing; disable Bluetooth when not in use

A company has a wireless network that uses WPA2-Personal with a shared passphrase. The security team discovers that an attacker has set up an evil twin AP and is capturing credentials from users who connect to it. The company wants to prevent this attack without replacing all client devices. Which solution is most effective?

Implement WPA3-Enterprise with certificate-based authentication

Disable SSID broadcast on the legitimate network

Change the WPA2-Personal passphrase to a longer, more complex one

Use MAC address filtering on the legitimate AP
