What is the main focus of the video?

• How to encrypt data on networks, especially Wi-Fi

• How to troubleshoot network issues

• How to increase network speed

• How to set up a wired network

What does SSID stand for?

• Service Set Identifier

• Secure Set Identifier

• Service Security Identifier

• Secure Service Identifier

What can you do to make your SSID harder to detect?

• Change the SSID frequently

• Make the SSID hidden

• Use a longer SSID

• Broadcast the SSID to all devices

Why is it important to encrypt data on wireless networks?

• To improve signal strength

• To reduce network traffic

• To prevent unauthorized access

• To increase network speed

What is used to scramble data into cypher text on a wireless network?

• A master key

• A public key

• A private key

• A network key

What is the role of the master key in wireless network encryption?

• To reduce network traffic

• To increase network speed

• To scramble data into cypher text

• To broadcast the SSID

What happens if the master key is transmitted?

• The network traffic reduces

• The SSID becomes hidden

• Any device listening in can decrypt the data

• The network speed increases

• WPA2

• Both WPA and WPA2

Which protocol is the most recent for encrypting data on wireless networks?

• WEP

• WPA

• WPA3

• WPA2

When is the handshake protocol used?

• After data transmission

• Before transmission to the device begins

• During data encryption

• Before setting up the network
