WPA2 (WiFi Protected Access II) is a WiFi security option that uses encryption andauthentication to protect the wireless network from unauthorized access or eavesdropping.WPA2 is the most secure and recommended WiFi security option among the options given. Ifsome light switches are no longer communicating after replacing the wireless router with a newdevice that uses WPA2, the most likely cause is that the light switches do not support WPA2.The light switches may need to be updated or replaced to be compatible with WPA2. The routeroperating on a different channel, the key not meeting password complexity requirements, andthe SSID not being broadcast are not likely causes of the light switches not communicating afterreplacing the wireless router with a new device that uses WPA2.Reference: CompTIA ITFundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page311.

Password reuse is the practice of using the same password for multiple accounts or services.Password reuse would increase the risk of account security on other sites if a large paymentwebsite was breached recently. If the attackers obtained the user's password from thebreached website, they could try to use it to access the user's accounts on other sites.Password reuse should be avoided and different passwords should be used for differentaccounts or services. Password history, password expiration, and password age are notpassword best practices that would mitigate this risk. Password history is the record of previouspasswords that a user has used for an account or service. Password expiration is the time limitfor using a password before it needs to be changed.
