A technician is setting up a SOHO wireless network for a healthcare office that does not have a server. The user requires the highest level of wireless security and various levels of desktop…

WPA uses TKIP encryption, which is weaker than WPA2's AES and is considered deprecated for security-sensitive environments.

WPA2 uses AES-CCMP encryption and is significantly stronger than WPA or WEP, making it the correct choice for the highest wireless security in a SOHO environment without enterprise infrastructure.

WEP is a severely broken encryption standard with known vulnerabilities that allow it to be cracked in minutes, making it unsuitable for any security-conscious deployment.

TKIP is the weaker encryption cipher associated with WPA; it is not a standalone security protocol and is inferior to WPA2's AES.

RADIUS is an enterprise authentication server protocol that requires a dedicated server, which this SOHO office explicitly does not have.

Multifactor authentication requires users to verify identity through two or more factors (e.g., password plus a mobile code), providing layered access control to cloud resources without requiring a local authentication server.

TACACS+ is a Cisco proprietary access control protocol that also requires a server infrastructure, which is unavailable in this scenario.

SSO (Single Sign-On) provides one set of credentials for multiple systems but does not itself provide multiple levels of authentication as required.
